Ovarian cancer (OC) is the fifth most frequent cause of cancer-associated mortality worldwide, and is accompanied by asymptomatic progression. Sirtuins (SIRTs) are a family of nicotinamide adenine dinucleotide-dependent protein deacetylases, comprising seven members (SIRT1, SIRT2, SIRT3, SIRT4, SIRT5, SIRT6 and SIRT7). Accumulating evidence has demonstrated that SIRTs act as prognostic estimators in certain types of cancer such as lung cancer, prostate cancer, gastric cancer, breast cancer and colorectal cancer. However, it remains unknown whether individual SIRTs can serve as independent prognostic factors in OC. In the present study, the Kaplan-Meier plotter online database was utilized to examine the prognostic values of SIRT mRNA expression in patients with OC. The results demonstrated that the overexpression of SIRT3, SIRT5, SIRT6 and SIRT7 mRNAs was associated with a good prognosis in patients, whereas elevated mRNA levels of SIRT1 and SIRT4 indicated poor survival in patients with OC. In addition, among the favorable predictors, SIRT3, SIRT5, SIRT6 and SIRT7 overexpression were associated with overall survival (OS), according to clinical characteristics, such as histological classification, clinical stage, pathology grade, drug therapy and tumor protein p53 mutation status in patients with OC. Similarly, SIRT4 mRNA overexpression was associated with poor OS in pathological grade III cancer. High SIRT1 and SIRT4 expression were associated with unfavorable OS at all clinical stages. Selleck Nafamostat Furthermore, SIRT1 and SIRT4 were negatively associated with OS in drug-treated patients. In summary, the present study demonstrated that the SIRT family is associated with the prognosis of human OC, suggesting that individual SIRTs may also act as prognostic predictors in patients.

Previous studies have demonstrated that Res can inhibit various different types of tumor growth. However, its role in renal cell carcinoma (RCC) remains largely unknown. The present study first demonstrated that Res inhibited cell viability and induced apoptosis in RCC 786-O cells. Further experiments revealed that Res damaged the mitochondria and activated caspase 3. In contrast, Z-VAD-FMK, a pan-caspase inhibitor, suppressed Res-induced apoptosis. Reactive oxygen species (ROS) were involved in the process of Res-induced apoptosis, and antioxidant N-acetyl cysteine could significantly attenuate this. Furthermore, Res activated c-Jun N-terminal kinase via ROS to induce autophagy, whereas inhibition of autophagy with chloroquine or Beclin 1 small interfering RNA aggravated Res-induced apoptosis, indicating that autophagy served as a pro-survival mechanism to protect 786-O cells from Res-induced apoptosis. Therefore, a combination of Res and autophagy inhibitors could enhance the inhibitory effect of Res on RCC.

MicroRNAs (miRNAs) represent a type of short endogenous non-coding RNA containing approximately 22 nucleotides, which are capable of regulating mRNAs at the post-transcriptional level in human cells. miRNAs have been demonstrated to mediate gene expression by influencing important regulatory genes. Accumulating evidence indicates that certain miRNAs are involved in RCC development. The present study investigated the underlying mechanism and functional role of miR-92a-3p in RCC cells using reverse transcription-quantitative polymerase chain reaction, western blotting, 3' UTR luciferase assay, cell proliferation assay and soft agar assay. The results demonstrated that miR-92a-3p expression level is significantly upregulated in RCC tissues and cell lines; however, F-box and WD repeat domain containing 7 (FBXW7) expression level was significantly downregulated in RCC tissues and cell lines. Subsequently, whether FBXW7 could be considered as a direct target of miR-92a-3p in RCC cells was investigated. The results demonstrated that miR-92a-3p overexpression significantly promoted RCC cell proliferation and colony formation. Conversely, miR-92a-3p downregulation significantly inhibited RCC cell proliferation and colony formation. In addition, FBXW7 knockdown significantly enhanced RCC cell proliferation and colony formation. Conversely, FBXW7 overexpression significantly inhibited RCC cell proliferation and colony formation. Collectively, these results demonstrated that miR-92a-3p/FBXW7 pathway may represent a novel strategy and therapeutic target for RCC.

The aim of the present study was to develop an early risk warning system for distant metastasis of hepatitis B virus (HBV)-associated primary HCC (HBV-HCC) with PVTT. Data from 346 patients (263 and 83 in the modeling and validation cohorts, respectively) who had received primary diagnoses of HBV-HCC and PVTT between January 2012 and June 2015 at Beijing Ditan Hospital (Beijing, China) were retrospectively examined. In the modeling cohort, univariate and multivariate logistic regression analyses were conducted to determine the factors that were significantly associated with distant metastasis. Furthermore, an early risk warning model for distant metastasis was proposed and validated through receiver operating characteristic curve analysis in the validation cohort. The results revealed that neutrophil to lymphocyte ratios of ≥2.31, red blood cell counts of ≥4.07×1012 cells/l, C-reactive protein levels of ≥7.02 mg/l, aspartate aminotransferase levels of ≥118.5 U/l and tumor thrombus site (at branch) were significantly positively associated with distant metastasis of HBV-HCC with PVTT (P1.000). A formula for predicting distant metastasis was obtained with an accuracy of ~70%. The results of the present study may allow for the early prediction of distant metastasis and facilitate the administration of appropriate treatment to improve the outcomes and prognosis of patients with intermediate to advanced HCC.
