Hypoxia inducible factor-la and colorectal cancer / 国际肿瘤学杂志

HIF-1α, a transcriptional activator regulating cells and tissues' response to hypoxia, can induce expression of a variety of factors and facilitate adaptation to hypoxia. Tumor hypoxic microenvironment and expression of HIF-1α is closely related to the occurrence of colorectal cancer, development, invasion, metastasis and prognosis, which becomes a hot spot in colorectal cancer research. To further clarify the process of colorectal cancer and to explore new treatment methods in colorectal cancer, HIF-1α in colorectal cancer studies was briefly reviewed.

Homeodomain-interacting protein kinase 2 and tumor signal transduction / 国际肿瘤学杂志

Homeodomain-interacting protein kinase 2(HIPK2)is a member of a member of the serine/threonine protein kinase family which localized in the mucleus.It is not only involved in advanced stage embryogenesis,development of nerve tissue,retina and muscular tissue,but also takes part in regulation of tumor signaling transduction,down-modulated expression of oncogene,induced apoptosis of tumor cells,and inhibited angiogeuesis of tumor.The regulation of HIPK2 in tumor signaling transduction pathway is associated with P53 signaling,Wnt/β-catenin pathway and hypoxia.
