Abstract:
B7-H6 is a ligand of NKp30, which is an activating receptor of natural killer (NK) cells. High expression of B7-H6 is found in certain types of tumor cells, such as lymphoma, leukemia and gastric carcinoma. The expression of B7-H6 can be induced by inflammatory stress in healthy cells. The expression of B7-H6 is significantly correlated with distant metastasis status and post-operative prognosis in cancer patients. The effectiveness of B7-H6 modified antitumor immunotherapy strategies had been verified in tumor-bearing mice, which opened a new door to targeted therapy. In this review, we will focus on the recent development on the roles of B7-H6 in tumor immunity, as well as mechanisms involved in the regulation of B7-H6 expression.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
