Differentiated embryonic chondrocyte (DEC) 1 has been reported to be involved in cell differentiation, hypoxia response, and cancer progression. Recent studies have demonstrated that hypoxia-inducible factor (HIF)-1α induces epithelial-mesenchymal transition (EMT) in carcinoma cells to facilitate cell invasiveness and metastasis. However, it remains unclear whether DEC1 participates in hypoxia-mediated EMT processes. In the present study, we reported that hypoxia induced DEC1 expression in hepatocellular carcinoma (HCC) HepG2 cells, and DEC1 negatively regulated expression of HIF-1α and E-cadherin in transcriptional/translational levels. Cell morphological changes were evaluated with hematoxylin and eosin (H-E) staining. Exposure to hypoxia caused spindle-like shape in some of the HepG2 cells, and DEC1 overexpression furthered these changes. In conclusions, DEC1 is involved in hypoxia-induced EMT processes via negatively regulating E-cadherin expression in HepG2 cells.

Multidrug resistance (MDR) refers to the ability of cancer cells to resist various anticancer drugs and release them from the cells. This phenomenon is widely recognized as a significant barrier that must be overcome in chemotherapy. MDR varies depending on the number and expression level of the ATP-binding cassette transporter (ABC transporter), which is expressed differently in various cancer cells.

Bisphenol S (BPS) is a typical endocrine disruptor associated with obesity. To observe BPS effects on lipid metabolism in HepG2 and SK-Hep-1 human HCC cells, a CCK-8 assay was used to assess cell proliferation in response to BPS, and the optimal concentration of BPS was selected. Biochemical indices such as triglyceride (TG) and total cholesterol (T-CHO), and oxidative stress indices such as malondialdehyde (MDA) and catalase (CAT) were measured.

, a dinoflagellate responsible for producing diarrhetic shellfish poisoning (DSP) toxins, poses significant threats to marine ecosystems, aquaculture industries, and human health. DSP toxins, including okadaic acid (OA), dinophysis toxin (DTX), and their diverse derivatives, continue to be identified and characterized. In this study, we report the isolation of four new diol esters of OA/DTX-1 from large-scale cultures of .

Despite the popular belief in the anti-tumor properties of venom (VBV), there is limited scientific evidence to support this claim. This study is the first to examine the anti-tumor effects of VBV on liver cancer, both alone and in combination with cisplatin (DDP), through in vitro and in vivo experiments. In vitro experiments evaluated VBV and its combination with DDP on HepG2 cell proliferation, invasion, migration, and apoptosis.
