MtDNA depletion influences the transition of CD44 subtypes in human prostate cancer DU145 cells.

Our earlier study revealed that long-term ethidium bromide application causes mitochondrial DNA depletion in human prostate cancer DU145 cell line (DU145(MtDP)), and this DU145(MtDP) subline appears to have expanded CD44(Bright) cell population than its parental wild type DU145 cells (DU145(WT)). Increasing evidence suggests that CD44(Bright) cells are highly cancer stem cell like, but it is not clear about their dynamic transition between CD44(Dim) and CD44(Bright) phenotypes in prostate cancer cells, and how it is affected by mitochondrial DNA depletion. To address these questions, four cell subpopulations were isolated from both DU145(WT) and DU145(MtDP) cell lines based on their CD44 expression level and mitochondrial membrane potential. The cell motility and colony formation capability of the fluorescence activated cell sorting-sorted cell subpopulations were further examined. It was discovered in the DU145(WT) cells that CD44(Dim) cells could transit into both CD44(Dim) and CD44(Bright) phenotypes and that CD44(Bright) cells were prone to sustain their CD44(Bright) phenotype as renewal. However, such transition principle was altered in the DU145(MtDP) cells, in which CD44(Bright) cells showed similar capability to sustain a CD44(Bright) phenotype, while the transition of CD44(Dim) cells to CD44(Bright) were suppressed. It is concluded that mitochondrial DNA depletion in the human prostate cancer DU145 cells influences their renewal and CD44 subphenotype transition. Such alterations may be the driving force for the enrichment of CD44(Bright) DU145 cells after the mitochondrial DNA depletion, although the molecular mechanisms remain unclear.

Circular RNA hsa_circ_0001564 facilitates tumorigenesis of osteosarcoma via sponging miR-29c-3p.

Circular RNAs are a novel type of non-coding RNAs generated from back splicing, which has been verified to mediate multiple tumorigenesis. However, the role of circular RNA in osteosarcoma is still unclear. In this study, we preliminarily screened the circular RNAs expression profiles in osteosarcoma and investigated the potential regulation mechanism. The circular RNAs expression profiles in osteosarcoma were screened using circular RNA microarray analysis, and results showed that there were 1152 circular RNAs upregulated and 915 circular RNAs downregulated in tumor tissue compared to adjacent tissue. Hsa_circ_0001564, located at 5q35.3 and its associated gene symbol is CANX, was one of the significantly overexpressed circular RNAs in osteosarcoma tissue, as well as in osteosarcoma cell lines. In functional experiments, hsa_circ_001564 knockdown significantly suppressed the proliferation activity, induced cell-cycle arrest in G0/G1 phase, and promoted apoptosis in HOS and MG-63 cells. Subsequently, we explored the probable mechanism of hsa_circ_001564, and fortunately, bioinformatics analysis revealed that miR-29c-3p contained the complementary binding region with hsa_circ_0001564, which was confirmed by dual-luciferase reporter assay. Moreover, rescue experiments illustrated that miR-29c-3p could reverse the oncogenesis effect of hsa_circ_001564. Our study discovers that hsa_circ_0001564 acts as miR-29c-3p sponge to mediate the tumorigenicity, which could act as a potential biomarker for the osteosarcoma and provide a novel insight for competing endogenous RNA mechanism in osteosarcoma.

Effect of Azithromycin on Airflow Decline-Free Survival After Allogeneic Hematopoietic Stem Cell Transplant: The ALLOZITHRO Randomized Clinical Trial.

Bronchiolitis obliterans syndrome has been associated with increased morbidity and mortality after allogeneic hematopoietic stem cell transplant (HSCT). Previous studies have suggested that azithromycin may reduce the incidence of post-lung transplant bronchiolitis obliterans syndrome.

Acute Kidney Injury in Patients with Cancer.

Optimising assessment of kidney function when managing localised renal masses.

Increased early and incidental detection, improved surgical techniques and technological advancement mean that the management of renal mass lesions is constantly evolving. The treatment of choice for renal mass lesions has historically been radical nephrectomy. Partial nephrectomy is now recommended for localised renal masses, owing to favourable renal functional outcomes. Ablative renal surgery confers a significant risk of chronic kidney disease. There are few studies assessing long term outcomes of nephrectomy on renal outcomes, and virtually no studies assessing long term outcomes for less invasive therapies such as ablation. Unless a renal mass is clearly benign on imaging, management decisions will be made with an assumption of malignancy. The content of this review applies to both benign and malignant renal mass lesions. We advocate for improved strategies for kidney function assessment and risk stratification, early targeted referral, and regular screening for chronic kidney disease for all patients after surgery.

Project DRIVE: A Compendium of Cancer Dependencies and Synthetic Lethal Relationships Uncovered by Large-Scale, Deep RNAi Screening.

Elucidation of the mutational landscape of human cancer has progressed rapidly and been accompanied by the development of therapeutics targeting mutant oncogenes. However, a comprehensive mapping of cancer dependencies has lagged behind and the discovery of therapeutic targets for counteracting tumor suppressor gene loss is needed. To identify vulnerabilities relevant to specific cancer subtypes, we conducted a large-scale RNAi screen in which viability effects of mRNA knockdown were assessed for 7,837 genes using an average of 20 shRNAs per gene in 398 cancer cell lines. We describe findings of this screen, outlining the classes of cancer dependency genes and their relationships to genetic, expression, and lineage features. In addition, we describe robust gene-interaction networks recapitulating both protein complexes and functional cooperation among complexes and pathways. This dataset along with a web portal is provided to the community to assist in the discovery and translation of new therapeutic approaches for cancer.

Defining a Cancer Dependency Map.

Most human epithelial tumors harbor numerous alterations, making it difficult to predict which genes are required for tumor survival. To systematically identify cancer dependencies, we analyzed 501 genome-scale loss-of-function screens performed in diverse human cancer cell lines. We developed DEMETER, an analytical framework that segregates on- from off-target effects of RNAi. 769 genes were differentially required in subsets of these cell lines at a threshold of six SDs from the mean. We found predictive models for 426 dependencies (55%) by nonlinear regression modeling considering 66,646 molecular features. Many dependencies fall into a limited number of classes, and unexpectedly, in 82% of models, the top biomarkers were expression based. We demonstrated the basis behind one such predictive model linking hypermethylation of the UBB ubiquitin gene to a dependency on UBC. Together, these observations provide a foundation for a cancer dependency map that facilitates the prioritization of therapeutic targets.

Fusobacterium nucleatum Promotes Chemoresistance to Colorectal Cancer by Modulating Autophagy.

Gut microbiota are linked to chronic inflammation and carcinogenesis. Chemotherapy failure is the major cause of recurrence and poor prognosis in colorectal cancer patients. Here, we investigated the contribution of gut microbiota to chemoresistance in patients with colorectal cancer. We found that Fusobacterium (F.) nucleatum was abundant in colorectal cancer tissues in patients with recurrence post chemotherapy, and was associated with patient clinicopathological characterisitcs. Furthermore, our bioinformatic and functional studies demonstrated that F. nucleatum promoted colorectal cancer resistance to chemotherapy. Mechanistically, F. nucleatum targeted TLR4 and MYD88 innate immune signaling and specific microRNAs to activate the autophagy pathway and alter colorectal cancer chemotherapeutic response. Thus, F. nucleatum orchestrates a molecular network of the Toll-like receptor, microRNAs, and autophagy to clinically, biologically, and mechanistically control colorectal cancer chemoresistance. Measuring and targeting F. nucleatum and its associated pathway will yield valuable insight into clinical management and may ameliorate colorectal cancer patient outcomes.

Clustered Mutation Signatures Reveal that Error-Prone DNA Repair Targets Mutations to Active Genes.

Many processes can cause the same nucleotide change in a genome, making the identification of the mechanisms causing mutations a difficult challenge. Here, we show that clustered mutations provide a more precise fingerprint of mutagenic processes. Of nine clustered mutation signatures identified from >1,000 tumor genomes, three relate to variable APOBEC activity and three are associated with tobacco smoking. An additional signature matches the spectrum of translesion DNA polymerase eta (POLH). In lymphoid cells, these mutations target promoters, consistent with AID-initiated somatic hypermutation. In solid tumors, however, they are associated with UV exposure and alcohol consumption and target the H3K36me3 chromatin of active genes in a mismatch repair (MMR)-dependent manner. These regions normally have a low mutation rate because error-free MMR also targets H3K36me3 chromatin. Carcinogens and error-prone repair therefore redistribute mutations to the more important regions of the genome, contributing a substantial mutation load in many tumors, including driver mutations.

Virus-directed enzyme prodrug therapy and the assessment of the cytotoxic impact of some benzimidazole derivatives.

Virus-directed enzyme prodrug therapy is one of the major strategy of increasing cytotoxicity of bioreductive agents. This research intended to examine new selected benzimidazole derivatives as a substrate for nitroreductase, the enzyme involved in nitroreduction which is responsible to the production of cytotoxic metabolites. In this way, the selectivity and strength of cytotoxicity can be raised. The effect of benzimidazoles on virus transfected cells and non-virus transfected cells A549 cell line was established by Annexin V + propidium iodide test, western blot, and polymerase chain reaction analysis of specific pro- and anti-apoptotic proteins in the corresponding gene expression and additionally nitroreductase gene expression. Our results proved the pro-apoptotic properties of all tested compounds in normoxia and hypoxia, especially according to virused A549 cells where the time of exposition was reduced from 48 to 4 h. In this shorten period of time, the strongest activity was shown by N-oxide compounds with nitro-groups. The apoptosis was confirmed by generation of BAX gene and protein and reduction of BCL2 gene and protein.

Novel targeted therapies for cancer cachexia.

Anorexia and metabolic alterations are the main components of the cachectic syndrome. Glucose intolerance, fat depletion, muscle protein catabolism and other alterations are involved in the development of cancer cachexia, a multi-organ syndrome. Nutritional approach strategies are not satisfactory in reversing the cachectic syndrome. The aim of the present review is to deal with the recent therapeutic targeted approaches that have been designed to fight and counteract wasting in cancer patients. Indeed, some promising targeted therapeutic approaches include ghrelin agonists, selective androgen receptor agonists, β-blockers and antimyostatin peptides. However, a multi-targeted approach seems absolutely essential to treat patients affected by cancer cachexia. This approach should not only involve combinations of drugs but also nutrition and an adequate program of physical exercise, factors that may lead to a synergy, essential to overcome the syndrome. This may efficiently reverse the metabolic changes described above and, at the same time, ameliorate the anorexia. Defining this therapeutic combination of drugs/nutrients/exercise is an exciting project that will stimulate many scientific efforts. Other aspects that will, no doubt, be very important for successful treatment of cancer wasting will be an optimized design of future clinical trials, together with a protocol for staging cancer patients in relation to their degree of cachexia. This will permit that nutritional/metabolic/pharmacological support can be started early in the course of the disease, before severe weight loss occurs. Indeed, timing is crucial and has to be taken very seriously when applying the therapeutic approach.

Profiles of lipids, blood pressure and weight changes among premenopausal Chinese breast cancer patients after adjuvant chemotherapy.

Adjuvant chemotherapy improves outcome of patients with early breast cancer. However, chemotherapy may be associated with long term toxicities. In this retrospective cohort study, the objectives were to determine body weight, body mass index (BMI), blood pressure and fasting lipids levels of young premenopausal Chinese breast cancer patients after adjuvant chemotherapy. Potential factors associated with these parameters were identified.

Vitamin D insufficiency correlates with peripheral B10 cells in patients with pituitary tumours.

The mechanism of pituitary gland tumour (PGT) is unclear. Aberrant immune tolerance is associated with the pathogenesis of tumour. Vitamin D and vitamin D receptor (VDR) are involved in the immune regulation. Interleukin (IL)-10 is one of the important immune regulatory molecules. This study aims to elucidate the role of VDR in the regulation of IL-10 in peripheral B cells of PGT patients. In this study, the peripheral blood samples were collected from PGT patients and healthy subjects. B cells were purified from the blood samples and analysed by RT-qPCR and Western blotting. The correlation between the expression of IL-10 and VDR in the B cells was assessed. We observed that the serum VitD levels were negatively correlated with IL-10 expression in peripheral B cells of patients with PGT. Low levels of VDR expression were found in peripheral B cells of PGT patients. Exposure to VitD suppressed the expression of IL-10 in B cells. The VDR bounds the transcription factor of IL-10 to interfere with the expression of IL-10 in B cells. The VDR agonists inhibited IL-10 expression in B cells from PGT patients. In conclusion, modulation of the expression of VDR can regulate the expression of IL-10 in peripheral B cells of PGT patients, which may contribute to the treatment of PGT.

MiR-429 suppresses glioblastoma multiforme by targeting SOX2.

Accumulating evidence has shown that miR-429 plays an important role in the development and progression of tumour. However, the role of miR-429 in glioblastoma multiforme (GBM) remains largely unknown. The present study is designed to investigate the function of miR-429 in GBM and to explore the molecular mechanism underlying its function. The expression level of miR-429 was detected in GBM tissues and cell lines by quantitative real-time polymerase chain reaction. The effect of overexpression of miR-429 on in vitro cell proliferation, apoptosis and invasion was examined. Western blot analysis was used to detect the influence of miR-429 on the expression of target gene, and Pearson analysis was used to calculate the correlation between the expression of targets gene and the miR-429 in GBM tissues. Our study shows that miR-429 is downregulated in GBM tissues compared with noncancerous tissues (P < .01). In addition, the expression of miR-429 in GBM cell lines is also significantly lower (P < .01). Enforced expression of miR-429 inhibits GBM cells proliferation, induces apoptosis and suppresses invasion and leads to the downregulation of the SOX2 protein. Moreover, the expression level of miR-429 in GBM tissues shows inverse relationship with the expression level of SOX2 protein. Our findings suggest that miR-429 represents a potential tumour-suppressive miRNA and plays an important role in GBM progression by directly targeting SOX2.

Desquamative erythrodermia.

Paraneoplastic dermatoses are a spectrum of cutaneous manifestations which may precede, coincide with or follow the diagnosis of cancer. Our study aims to remind clinicians that desquamative erythrodermia is a form of paraneoplastic dermatosis which may occur during hematologic malignancies. Hence the importance of a complete assessment to identify a neoplastic process in the presence of these clinical signs and especially when they are suspect.

Chondroblastic osteosarcoma of the distal tibia: a rare case report.

Chondroblastic osteosarcoma, representing about 25% of osteosarcoma, is a fatal primary malignancy of the skeleton if not diagnosed and treated appropriately. It most commonly occurs in the long bones of the extremities near the metaphyseal growth plates. In this report, we describe the occurrence of chondroblastic osteosarcoma involving the left distal tibia in a 14-year-old male. The diagnosis was confirmed by the histological examination of a surgical biopsy. The patient was treated by both surgery and neoadjuvant chemotherapy. No recurrence was noted at 3 years of follow-up. To our knowledge, only two cases describing chondroblastic osteosarcoma of the distal tibia had been reported through English medical literature. Therefore, the aim of our article is to make the clinician aware of this rare clinical presentation and also to provide a comprehensive review of the literature related to this uncommon malignant tumour.

Cascade Fumarate Hydratase mutation screening allows early detection of kidney tumour: a case report.

Fumarate hydratase (FH) deficiency is a rare autosomal recessive disorder which results in a major defect in cellular metabolism. It presents in infancy with progressive encephalopathy, hypotonia, seizures and failure to thrive and is often fatal in childhood. It is caused by mutations in the FH gene (1q42.1) that result in deficiency of the citric acid cycle enzyme fumarate hydratase, resulting in accumulation of fumaric acid. Heterozygous germline mutations in the FH gene predispose to an aggressive autosomal dominant inherited early-onset kidney cancer syndrome: hereditary leiomyomatosis and renal cell cancer (HLRCC).

TACE plus percutaneous chemotherapy-lipiodol treatment of unresectable pedunculated hepatocellular carcinoma.

Pedunculated hepatocellular carcinoma (P-HCC) is rare type of HCC. The study aimed to evaluate the clinical features and outcomes of unresectable P-HCC treated with transcatheter arterial chemoembolization (TACE) and percutaneous chemotherapeutic agents lipiodol emulsion (CALE) injection. The clinical features and outcomes of 25 patients with unresectable P-HCC treated with TACE plus percutaneous CALE injection were retrospectively reviewed, and factors associated with outcomes were analyzed. Comparison with nonpedunculated unresectable HCC was also performed. Patients underwent a median of 4 TACE sessions and received a median of 2 percutaneous CALE injections. The 1-, 2-, 3-, and 5-year actuarial survival rates were 78.9%, 52.6%, 42.1%, and 12.0%, respectively, for patients with P-HCC, and median survival was 27 months (95% confidence interval, 22.6-43.2 months). Patients with P-HCC had better overall survival than those with nonpedunculated HCC (NP-HCC) (P = .002). Vascular invasion and abdominal lymph node metastasis were poor prognostic factors for overall survival in patients with P-HCC. TACE plus percutaneous CALE injection is a safe and effective treatment for unresectable P-HCC. Patients with unresectable P-HCC might have better overall survival than those with NP-HCC after TACE plus percutaneous CALE injection. However, their prognosis remains poor.

The prognostic value of preoperative inflammation-based prognostic scores and nutritional status for overall survival in resected patients with nonmetastatic Siewert type II/III adenocarcinoma of esophagogastric junction.

Immune and nutritional status of patients have been reported to predict postoperative complications, recurrence, and prognosis of patients with cancer. Therefore, this retrospective study aimed to explore the prognostic value of preoperative inflammation-based prognostic scores [neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR)] and nutritional status [prognostic nutritional index (PNI), body mass index (BMI), hemoglobin, albumin, and prealbumin] for overall survival (OS) in adenocarcinoma of esophagogastric junction (AEG) patients.

Copy number variations of neurotrophic tyrosine receptor kinase 3 (NTRK3) may predict prognosis of ovarian cancer.

Platinum resistance is a critical barrier for clinicians to improve the survival of ovarian cancer. Our study evaluated the correlation between copy number variations (CNVs) of neurotrophic tyrosine receptor kinase 3 (NTRK3) and the prognosis of ovarian cancer, which might predict platinum resistance in ovarian cancer patients.Array comparative genomic hybridization (CGH) was used to test gene backgrounds between platinum-sensitive and platinum-resistant relapsed populations and CNVs of NTRK3 were indicated by cluster analysis. Fluorescence in situ hybridization (FISH) was adopted in 41 cases for further verification, which confirmed the results of array CGH. Spearman's rank correlation analysis and χ test were used to evaluate the accuracy of CNVs of NTRK3 which predicted platinum-sensitive or platinum-resistant recurrence.We detected CNVs of NTRK3 between 2 groups by array CGH, and amplification of NTRK3 was confirmed by FISH in the platinum-sensitive recurrence group with enlarged samples. The test concordance of 2 methods was 78.6%. Among 41 cases with satisfied FISH results, the median time to recurrence (TTR) of patients with amplified and nonamplified NTRK3 were respectively 18 and 5 months (P <.01). The cut-off value of TTR to differentiate platinum-sensitive or platinum-resistant recurrence was 6 months in accordance with clinical practice. According to the above standard, 15 cases with NTRK3 amplification were platinum-sensitive and 12 cases without NTRK3 amplification were platinum-resistant recurrences which demonstrated that the accuracy of NTRK3 amplification/nonamplification to predict recurrent types was 65.9% (27/41).CNVs of NTRK3 were associated with platinum-sensitive and platinum-resistant recurrences. Amplification of NTRK3 perfectly predicted platinum-sensitive relapse of ovarian cancer.

18F-fluoro-deoxy-glucose positron emission tomography combined with computed tomography can reliably rule-out infection and cancer in patients with anti-neutrophil cytoplasmic antibody-associated vasculitis suspected of disease relapse.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of autoimmune diseases characterized by systemic inflammation in small- to medium-sized blood vessels. Although immunosuppressive therapy has greatly improved the prognosis for these patients, there are still significant comorbidities, such as cancer and infection, associated with AAV. These comorbidities are often indistinguishable from an underlying AAV disease relapse, and create a clinical conundrum, as these conditions are normally contraindications for immunosuppressive treatment. Thus, it is important to be able to rule out these comorbidities before initiation of immunosuppressive treatment. We examined F-fluoro-deoxy-glucose positron emission tomography combined with computed tomography (FDG-PET/CT)'s value in ruling out cancer or infection in patients with AAV.Data were obtained retrospectively for a clinically based cohort of AAV patients who underwent FDG-PET/CT during 2009 to 2014 owing to a suspicion of cancer, infection, or both cancer and infection indistinguishable from disease relapse. FDG-PET/CT conclusions were compared to the final diagnoses after follow-up analysis (mean 43 months).A total of 19 patients were included who underwent a total of 26 scans. The results of FDG-PET/CT outcome compared to final diagnosis were: 9 true positives, 3 false positives, 13 true negatives, and 1 false negative. The diagnostic probabilities for FDG-PET/CT with respect to overall comorbidity (i.e., cancer or infection) were: sensitivity 90% ( 95% confidence interval [CI] 60%-98%), specificity 81% ( 95% CI 57%-93%), positive predictive value 75% (95% CI 47%-91%), negative predictive value 93% (95% CI 68%-99%), and accuracy 84% (95% CI 66%-94%).FDG-PET/CT had a high negative predictive value and ruled out the comorbidities correctly in all but one case of urinary tract infection, a well-known limitation. Our study showed FGD-PET/CT's promise as an effective tool for ruling out cancer or infection in patients with AAV albeit in a limited population.

S-1 monotherapy versus S-1 combination therapy in gemcitabine-refractory advanced pancreatic cancer: A meta-analysis (PRISMA) of randomized control trials.

Pancreatic cancer (PC) is one of the most lethal digestive system tumors. Most new cases are diagnosed based on metastasis or local aggression and are known as "advanced PC." Recently, studies investigating S-1 have indicated that it has a better clinical curative effect on PC. We conducted a meta-analysis to evaluate the efficacy and safety of S-1 monotherapy compared with S-1 combination regimens in patients with gemcitabine (GEM)-refractory PC.

Intermediate-stage hepatocellular carcinoma patients with a high HBV-DNA load may benefit from postoperative anti-hepatitis B virus therapy.

Liver resection may be beneficial in intermediate-stage hepatocellular carcinoma (HCC), though the benefit of postoperative anti-hepatitis B virus (HBV) therapy in these patients remains unclear. In this study, we sought to evaluate the efficacy of postoperative anti-HBV for intermediate-stage HCC patients who underwent radical liver resection.According to inclusion and exclusion criteria, this study enrolled 202 HCC patients who underwent liver resection and had a high HBV-DNA load. The patients were divided into 2 groups on the basis of postoperative anti-HBV therapy: group A included patients undergoing postoperative anti-HBV therapy, whereas group B patients did not receive any postoperative anti-HBV therapy. Factors including baseline demographics, tumor characteristics, overall long-term survival, tumor-free survival, and tumor recurrence rate were compared between the 2 groups. Moreover, univariate and multivariate analyses were used to identify risk factors of HCC recurrence.Baseline demographics and tumor characteristics were comparable between the groups. The 1-, 3-, and 5-year overall survival rates in group A were 91.3%, 80.9%, and 66.1%, respectively, values that were significantly increased compared with group B (91.7%, 60.7%, and 52.4%, respectively, P = .019). Group A patients also exhibited enhanced 1-, 3-, and 5-year tumor-free survival compared with group B patients (87.0%, 67.0%, and 62.6%, respectively, in group A; 82.1%, 50.0%, and 42.9% in group B, P = .002). In addition, the tumor recurrence rate in group B was significantly increased compared with group A (P < .01). Univariate and multivariate analyses indicated lack of postoperative anti-HBV therapy [hazard ratio (HR) = 0.882; 95% confidence interval (CI), 0.712-0.938; P = .042] to be a predictor of tumor recurrence.For intermediate-stage [Barcelona Clinic Liver Cancer (BCLC) stage B] HCC with a high HBV-DNA load, postoperative anti-HBV therapy after curative resection should be routine adjuvant therapy.
