RESUMEN

Signaling pathways in hepatocellular carcinoma are primarily mediated by the phosphorylation and ubiquitination of post-translational proteins. In mammalian cells, ubiquitin-specific proteases (USPs) account for the majority of protein deubiquitination activities. In addition to transcriptional and post-translational regulation, ubiquitination plays an important role in the regulation of key proteins. There is a possibility that altered biological processes may lead to serious human diseases, including cancer. Recent studies have revealed the role of USPs in hepatocellular carcinoma tumorigenesis. The purpose of this review is to summarize the involvement of this class of enzymes in the regulation of cell signaling in hepatocellular carcinoma and the therapeutic development of inhibitors that target USPs, which may lead to novel therapies to treat hepatocellular carcinoma.

RESUMEN

Osteosarcoma (OS) is the most common malignant bone tumor in children and adolescents. It is characterized by a rapid progression, poor prognosis, and early pulmonary metastasis. Over the past 30 years, approximately 85% of patients with osteosarcoma have experienced metastasis. The five-year survival of patients with lung metastasis during the early stages of treatment is less than 20%. The tumor microenvironment (TME) not only provides conditions for tumor cell growth but also releases a variety of substances that can promote the metastasis of tumor cells to other tissues and organs. Currently, there is limited research on the role of the TME in osteosarcoma metastasis. Therefore, to explore methods for regulating osteosarcoma metastasis, further investigations must be conducted from the perspective of the TME. This will help to identify new potential biomarkers for predicting osteosarcoma metastasis and assist in the discovery of new drugs that target regulatory mechanisms for clinical diagnosis and treatment. This paper reviews the research progress on the mechanism of osteosarcoma metastasis based on TME theory, which will provide guidance for the clinical treatment of osteosarcoma.

RESUMEN

PURPOSE: To investigate the synergistic effect of vitamin D and neferine on the growth and metastasis of colorectal cancer (CRC). METHODS: The synergistic effect of biologically active form of vitamin D, VD3 and neferine on the treatment of CRC was investigated by bliss analysis. Colony formation and wound healing ability, migration and invasion ability, and epithelial mesenchymal transition of HCT-116 cells, as a response to the combination treatment with VD3 and neferine were evaluated. RESULTS: VD3 and neferine showed a synergistic effect on CRC cell growth at a relatively low dose. The wound healing and colony formation capacity, cell migration and invasion abilities were all decreased by combination use of VD3 and neferine, compared to the VD3 or neferine treated single group. Furthermore, VD3 and neferine significantly decreased the expressions of N-cadherin, vimentin, snail, and slug in HCT-116 cells. CONCLUSION: These data suggest that neferine enhances the anticancer capability of VD3 and reduces the dose dependency of VD3. The combination of vitamin D with neferine appears to be a potential therapeutic strategy for CRC.
