Abstract:
Chromosome instability syndromes (CIS) are autosomal recessive genetic disorders associated with defects in cell cycle regulation following DNA damage. Although most of the proteins involved in these syndromes have been identified as part of the MRN complex, little is known about their physiological functions and their interactions with other molecules that might explain the wide clinical presentation found in CIS patients. Here we discuss several observations suggesting that PC3 (BTG2/TIS21) - a protein involved in G1-S checkpoint progression control - might play a role in these pathologies.

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.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
