Cyclin d1 overexpression sensitizes breast cancer cells to fenretinide.
PURPOSE Fenretinide has shown promise in the chemoprevention of breast cancer, a tumor type in which the oncogene cyclin D1 is overexpressed frequently. We aimed at determining the effect of cyclin D1 level on the response to fenretinide treatment. EXPERIMENTAL DESIGN Stable clones of T47-D cells were created to overexpress cyclin D1 or a mutant of cyclin D1, injected in nude mice for xenogra...
متن کاملEvaluation of Cyclin D1 Expression in Esophageal Squamous Cell Carcinoma and its Effect on Response Rate to Neo- adjuvant Chemoradiotherapy
Background and Objective: Esophageal cancer especially squamous cell carcinoma (SCC) is one of the most common gastro intestinal malignancies in north part of Iran (Khorasan). The standard treatment for esophageal cancer is surgical resection, but its outcome remains poor. Then, the oncologists try to treat this cancer with sandwich protocols especially neo-adjuvant chemo-radiotherapy. Sever...
متن کاملInterphase APC/C–Cdc20 inhibition by cyclin A2–Cdk2 ensures efficient mitotic entry
Proper cell-cycle progression requires tight temporal control of the Anaphase Promoting Complex/Cyclosome (APC/C), a large ubiquitin ligase that is activated by one of two co-activators, Cdh1 or Cdc20. APC/C and Cdc20 are already present during interphase but APC/C-Cdc20 regulation during this window of the cell cycle, if any, is unknown. Here we show that cyclin A2-Cdk2 binds and phosphorylate...
متن کاملT-loop deletion of CDC2 from breast cancer tissues eliminates binding to cyclin B1 and cyclin-dependent kinase inhibitor p21.
The eukaryotic cell cycle is regulated by a highly conserved family of protein kinases, the cyclin-dependent kinases (CDKs). Monomeric free CDKs do not possess enzymatic activity, largely due to the steric hindrance caused by the T-loop at the entrance of the catalytic cleft, making ATP inaccessible to the substrate. Binding of a cyclin, primarily to the NH2-terminal lobe of the CDK that surrou...
