Development and validation of a prognostic classifier based on HIF-1 signaling for hepatocellular carcinoma.

Development and validation of a prognostic classifier based on HIF-1 signaling for hepatocellular carcinoma. Aging (Albany NY). 2020 Feb 21;12: Authors: Deng F, Chen D, Wei X, Lu S, Luo X, He J, Liu J, Meng T, Yang A, Chen H Abstract HIF-1 (hypoxia-inducible factor 1) signaling played a vital role in HCC (hepatocellular carcinoma) prognosis. We aimed to establish an accurate risk scoring system for HCC prognosis prediction and treatment guidance. 424 samples from TCGA (The Cancer Genome Atlas) and 445 samples from GSE14520 dataset were included as the derivation and validation cohort, respectively. In the derivation cohort, prognostic relevant signatures were selected from sixteen HIF-1 related genes and LASSO regression was adopted for model construction. Tumor-infiltrating immune cells were calculated using CIBERSORT algorithm. HIF-1 signaling significantly increased in HCC samples compared with normal tissues. Scoring system based on SLC2A1, ENO1, LDHA and GAPDH exhibited a continuous predictive ability for OS (overall survival) in HCC patients. PCA and t-SNE analysis confirmed a reliable clustering ability of risk score in both cohorts. Patients were classified into high-risk and low-risk groups and the survival outcomes between the two groups showed significant differences. In the derivation cohort, Cox regression indicated the scoring system was an independent predictor for OS, which was validated in the validation cohort. Different infiltrating im...

Authors: Jia M, Xiong Y, Li M, Mao Q Abstract Chemotherapy is critical for the treatment of hepatocellular carcinoma (HCC). Despite the pro-apoptotic effects of corosolic acid (CA) treatment, its underlying mechanism is not completely clear. The aim of this study was to determine the molecular mechanism of CA in HCC treatment. MTT assay was used to determine the IC50 of CA. Immunoprecipitation and immunofluorescence were used to detect the interaction between and subcellular localization of Yes-associated protein (YAP) and mouse double minute 2 (MDM2). In addition, in vivo xenotransplantation was performed to asses...

This study aims to compare survival outcome after receiving radiofrequency ablation (RFA) and surgical resection (SR) for solitary hepatocellular carcinoma (HCC) with size large as 5 cm.Methods: The SEER database was queried for patients with HCC tumors who were treated with RFA or SR between 2004 and 2015. Univariate and multivariate Cox analysis was used to assess the influence of potential variables on the patients' outcome. Additionally, propensity score matching (PSM) and multiple imputations (MI) were used as sensitivity analyses.Results: Of 1,985 cases, 934 patients received RFA treatment, while the rest underwent s...

This study aimed to investigate the effect of hydroxypyridinone-coumarin (HPC) on MHCC97 and HepG2 human HCC cells and the mechanisms involved. MATERIAL AND METHODS MHCC97 and HepG2 human HCC cells were cultured in vitro. An MTT cytotoxicity assay was used to assess cell viability and proliferation, with and without treatment with HPC. Cell autophagosomes were labeled with GFP-LC3 using confocal fluorescence microscopy. Western blot was used to measure protein expression. RESULTS HPC significantly reduced the cell proliferation rate in a concentration-dependent manner, with 2 µM of HPC resulting in a reduced prolifer...

Jeon Hepatocellular carcinoma (HCC) accounts for approximately 90% of all cases of primary liver cancer; it is the third most frequent cause of cancer-related death worldwide. In early-stage disease, surgical resection and liver transplantation are considered curative treatments. However, the majority of HCC patients present with advanced-stage disease that is treated using palliative systemic therapy. Since HCC is heterogeneous owing to its multiple etiologies, various risk factors, and inherent resistance to chemotherapy, the development of an effective systemic treatment strategy for HCC remains a considerable chall...

Authors: Wang J, Yang X, Han S, Zhang L Abstract Disrupted centrosome-associated family protein expression can result in the detrimental duplication of centrosomes, causing genomic instability and subsequent carcinogenesis. Limited research has demonstrated that centrosomal protein 131 (CEP131) exhibits oncogenic activity in osteosarcoma, hepatocellular carcinoma and breast cancer. The present study demonstrated that there is an association between CEP131 expression and advanced Tumor-Node-Metastasis stage (P=0.016), and positive regional lymph node metastasis (P=0.023) in 91 cases of non-small cell lung cancer. A5...
