Among 25 cases with cyclin D1 expression, 6 had metastases, whereas only 2 of 45 cases with no cyclin D expression had metastases ([chi square]-test: p=0.014; Fisher exact test: p=0.021), indicating that the expression of cyclin D1 is not crucial for the development of metastases in lymph nodes.
Cyclin D mainly regulates the G1 phase of cells, and its major synthesis is activated by AP1 (activation of growth factor GF).
Therefore, besides direct downregulation of the level of actin protein, RRI and SI reduce the level of p53 and p21, subsequently invert their inhibition on cyclin D or cyclin E, probably together with a direct promotion of cyclin B with SI, and finally result in MK endomitosis.
The synthesis of Cyclin D starts during G1 and helps in cell cycle transition from G1 to S phase.
FoxO 1a participates in the regulation of gluconeogenesis and glycogenolysis by controlling the expression of glucose-6-phosphatase and phosphoenolpyruvate carboxykinase, and it also participates in cell cycle regulation by downregulating the transcription of cyclin D [15, 16].
Ongoing studies are assessing the role of cyclin D, a CDK activator corresponding to progression through the cell cycle.
New York, NY, May 10, 2013 --(PR.com)-- One of the researchers said, “Blocking cyclin D represents a highly selective anticancer strategy that specifically targets cancer cells without significantly affecting normal tissues."
Daidzein treatment resulted in decreases in cyclin D, CDK2, and CDK4, whereas the expression of CDK6 and cyclin E was unchanged.
