Abstract:
Cyclin D1 (CCND1) is a key regulatory protein, playing a critical role in the transition from G1 to S phase of the cell cycle. We have evaluated the association between CCND1 A870G polymorphism and risk of cervix cancer in north Indian women by using PCR-RFLP method. This association was estimated by computing odds ratio (ORs) and a 95% Confidence Intervals (95% CI) using a Multivariate Logistic Regression Analysis. No significant association was observed between CCND1 genotypes and overall risk of cervix cancer. But when stratified histologically, statistically significant (OR: 3.7, 95% CI: 1.56-8.87, P: 0.001) increased risk of squamous cell carcinoma (SCC) was observed for individuals with AA genotype. Thus our findings suggest that CCND1 (G870A) polymorphism may be associated with increased risk of SCC of the uterine cervix in north Indian women.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

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,...
