Abstract:
Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) was identified in 1997 as a tumor suppressor gene through mapping of homozygous mutations occurring in multiple sporadic tumor types and in patients with cancer predisposition syndromes including Cowden disease (Song et al., 2012). Since that time, PTEN has emerged as one of the most frequently mutated or deleted genes in human cancers, including human skin cancers. In particular, loss of PTEN function through mutation or deletion has been observed in up to 70% of melanoma cell lines, and epigenetic silencing of PTEN has been observed in 30-40% of malignant melanomas (Mehnert and Kluger, 2012).

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

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.

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
