Functional studies revealed that CYP4F2 overexpression inhibited HCC cell proliferation and migration, and induced apoptosis. Furthermore, CYP4F2 overexpression repressed the expression of genes in the nuclear factor, erythroid 2 like 2 (Nrf2) signaling pathway, including Nrf2, heme oxygenase-1 and ferritin heavy chain 1, while increasing NAD(P)H quinone dehydrogenase 1 expression, suggesting that CYP4F2 overexpression reversed the antioxidant response of liver cancer cells. Overall, the present findings indicated that CYP4F2 may be a potential prognostic biomarker for predicting tumorigenesis and long-term survival rates in patients with HCC.Skin cutaneous melanoma (SKCM) is the most aggressive type of skin cancer, with a high rate of metastasis and mortality; however, identification of biomarkers for the treatment of SKCM is required. Cluster of differentiation (CD)38 has emerged as an effective target for therapeutic drugs in several types of cancer, such as chronic lymphocytic leukemia and multiple myeloma. In the present study, to determine the contribution of CD38 to the diagnosis of SKCM, Gene Expression Profiling Interactive Analysis 2 and University of Alabama Cancer Database online tools were used to analyze The Cancer Genome Atlas-SKCM dataset. Moreover, Search Tool for the Retrieval of Interacting Genes/Proteins and GeneMANIA databases were used to determine protein-protein interaction networks and potential functions. To the best of our knowledge, the results of the present study indicated for the first time that high expression levels of CD38 were a favorable diagnostic factor for SKCM. Moreover, a correlation between CD38 expression levels and the survival probability of patients with SKCM was identified. Integrative analysis predicted that nine genes were correlated with CD38 in SKCM, and the similarity of these genes in SKCM expression and a survival heatmap was verified. Gene ontology enrichment analysis using the Metascape tool revealed that CD38 and its correlated genes were significantly enriched in lymphocyte activation and T cell differentiation regulation. Collectively, the bioinformatics analysis revealed that CD38 might serve as a potential diagnostic predictor for SKCM.Sirtuins are mammalian homologs of yeast silent information regulator two (SIRT) and are a highly conserved family of proteins, which act as nicotinamide adenine dinucleotide (NAD+)-dependent histone deacetylases. The seven sirtuins (SIRT1-7) share a conserved catalytic core domain; however, they have different enzyme activities, biological functions, and subcellular localizations. Among them, mitochondrial SIRT4 possesses ADP-ribosyltransferase, NAD+-dependent deacetylase, lipoamidase, and long-chain deacylase activities and can modulate the function of substrate proteins via ADP-ribosylation, delipoylation, deacetylation and long-chain deacylation. SIRT4 has been shown to play a crucial role in insulin secretion, fatty acid oxidation, amino acid metabolism, ATP homeostasis, apoptosis, neurodegeneration, and cardiovascular diseases. In addition, recent studies have demonstrated that SIRT4 acts as a tumor suppressor. Here, the present review summarizes the enzymatic activities and biological functions of SIRT4, as well as its roles in cellular metabolism and human cancer, which are described in the current literature.The fibrinogen-to-albumin ratio (FAR), reflecting the systemic coagulation, nutritional and inflammation status of patients, has matured into a prognostic marker for several tumor types. However, only a few studies have assessed the utility of the FAR as a prognostic indicator in patients with advanced gastric cancer (GC) receiving first-line chemotherapy. In the present study, 273 patients with advanced GC who received first-line chemotherapy between January 2014 and January 2019 at the Cancer Hospital of China Medical University (Shenyang, China) were retrospectively analyzed. Using the cut-off values determined by receiver operating characteristic (ROC) analysis, the patients were divided into low-FAR (≤10.03) and high-FAR (>10.03), low-fibrinogen ( less then 3.8 g/l) and high-fibrinogen (≥3.8 g/l), and low-albumin ( less then 40.55 g/l) and high-albumin (≥40.55 g/l) groups. Elenestinib ic50 The associations of the pretreatment FAR and clinicopathological characteristics with progression-free survival (PFS) and overall surprognosis, including multiple metastases, TNM stage IV and abnormal CA72-4 levels, the FAR may be used as an accurate prognostic marker (all P less then 0.05), and may also reliably identify patients with poor prognosis among those with normal fibrinogen and albumin levels (all P less then 0.001). The FAR was indicated to be a valuable marker for predicting PFS and OS in patients with advanced GC receiving first-line chemotherapy and is superior to either fibrinogen or albumin alone.Since human bladder cancer (BC) is a common malignancy of the urinary system with poor prognosis, it is crucial to clarify the molecular mechanisms of BC development and progression. To the best of our knowledge, the current study demonstrated for the first time that miR-489-3p suppressed BC cell-derived tumor growth in vivo via the downregulation of histone deacetylase 2 (HDAC2). According to the results, expression levels of miR-489-3p were lower in BC tissues compared with corresponding normal tissues. Expression of miR-489-3p mimics in BC-derived T24 and 5637 cells resulted in a significant reduction in proliferation and migration rates. Furthermore, bioinformatics analyses indicated that HDAC2 may be a potential downstream target of miR-489-3p. In contrast to miR-489-3p, HDAC2 was expressed at higher levels in BC tissues compared with corresponding normal tissues. Additionally, small interfering RNA-mediated knockdown of HDAC2 caused a marked decrease in the proliferation and migration rates of T24 and 5637 cells. Consistent with these observations, expression of miR-489-3p mimics attenuated the growth of xenograft tumors arising from T24 cells and resulted in HDAC2 downregulation. In conclusion, the results of the current study indicated that the miR-489-3p/HDAC2 axis serves a role in the development and/or the progression of BC and may be a potential molecular target for the development of a novel strategy to treat patients with BC.
