Also, the expression of Cyclin D should be decreased at the G2/M checkpoint (Figure 4). (ptgcn.com)

Based on these results, two phase III trials are evaluating abemaciclib in combination with a hormonal agent: MONARCH 2 -(abemaciclib plus fulvestrant [Faslodex] in endocrine-pretreated hormone receptor-positive HER2-negative breast cancer), and MONARCH 3 (abema-ciclib plus a nonsteroidal aromatase inhibitor as first-line treatment for metastatic hormone receptor-positive or HER2-negative breast cancer).

The synthesis of another G1 phase cyclin, cyclin E, increases in late G1 and decreases once DNA replication is initiated. (biomedcentral.com)

The cell cycle is a tightly regulated process that is controlled by the conserved cyclin-dependent kinase (CDK)-cyclin protein complex 1 . (nature.com)

It helps regulate the transition to S PHASE and its kinase activity is inhibited by CYCLIN-DEPENDENT KINASE INHIBITOR P18. (bvsalud.org)

D-type cyclins are frequently deregulated in human cancer and promote cell division in part through activation of CDK4/6. (bvsalud.org)

These two antibodies detect unique, non-overlapping epitopes on human CDK6. (cellsignal.com)
There are many kinases (over 500 in the human body ). (callaix.com)
