Abstract Background: MicroRNAs (miRNAs) are dysregulated in hypoxia-induced hepatocellular carcinoma (HCC). This study probed the regulatory mechanism of miR-3156-5p on HCC under hypoxia. Methods: HCC cells (HepG2) were exposed to normoxia or hypoxia, and the conditioned medium (CM) of HepG2 was applied. Quantitative reverse transcription PCR (qRT-PCR) was implemented to analyze the miR-3156-5p profile. The cell counting kit-8 (CCK-8) assay and the colony formation experiment were conducted to measure cell proliferation, colony formation, and angiogenesis. Results: The results manifested that miR-3156-5p was up-regulated in HCC cells and endothelial cells under hypoxia, and up-regulating miR-3156-5p boosted HCC cell proliferation, endothelial cell angiogenesis, and HIF-1α/VEGF expression. Conclusions: miR-3156-5p activates the HIF-1α/VEGF pathway by hampering SOCS5, thereby enhancing the angiogenic potential of hypoxia-induced endothelial cells in HCC cells.

Background/Aims: Overexpression of cytosolic sulfotransferase 2B1b (SULT2B1b) has been commonly found in colorectal and hepatocellular carcinoma, suggesting that SULT2B1b might act as a potential oncogenic protein. However, its clinical significance and biological role in gastric cancer progression remain largely unknown. Methods: Expressions of SULT2B1b in clinical gastric cancer (GC) samples were examined using qRT-PCR and Western blot. Results: SULT2B1b was markedly overexpressed in human GC samples, and positively correlated with vessel density and associated with poor clinical features. We also demonstrated that overexpression of SULT2B1b resulted in increased tumor angiogenesis and tumor growth in mouse GC models. In addition, ablation of SULT2B1b in human GC cells lines BGC823 and MKN45 decreased the capability of the cells to recruit endothelial cells. Moreover, depletion of SULT2B1b in GC cells reduced VEGF-A expression by downregulating SP1 and AP2. Conclusion: Our results suggested that the SULT2B1b-mediated angiogenic pathway could serve as biomarkers for GC diagnosis and prognosis, and suppressing SULT2B1b-mediated angiogenic signaling might be a promising strategy for developing novel GC treatment.
