Living with or without cyclins and cyclin-dependent kinases [PDF]
Entry into, progression through, and exit from the G1 phase of the mammalian cell cycle in response to extracellular mitogenic cues are presumed to be governed by cyclin-dependent kinases (Cdks) regulated by the D-type and E-type cyclins. Studies performed over more than a decade have supported the view that these holoenzymes are important, if not ...

Cyclin E, a redundant cyclin in breast cancer [PDF]
Cyclin E is an important regulator of cell cycle progression that together with cyclin-dependent kinase (cdk) 2 is crucial for the G 1 /S transition during the mammalian cell cycle. Previously, we showed that severe overexpression of cyclin E protein in tumor cells and tissues results in the appearance of lower ...

Overexpression of Cyclin A and Cyclin B1Proteins in Astrocytomas
Abstract Background. —Cyclins are proteins that are expressed during the progression of a normal cell through the cell cycle. In a number of cancers, overexpression of cyclin A and cyclin B1 proteins has been reported, and in some instances the levels of expression correlated well with the ...

Cyclin C: The Story of a Non-Cycling Cyclin [PDF]
The class I cyclin family is a well-studied group of structurally conserved proteins that interact with their associated cyclin-dependent kinases (Cdks) to regulate different stages of cell cycle progression depending on their oscillating expression levels.

Increased protein synthesis is a key process in melanoma, which is regulated by the ALDH18A1 gene encoding pyrroline-5-carboxylate synthase (P5CS). P5CS is involved in proline biosynthesis and targeting ALDH18A1 has previously been shown to inhibit ...

Background The cell cycle is promoted by activation of cyclin dependent kinases (Cdks), which are regulated positively by cyclins and negatively by Cdk inhibitors. Proliferation of carcinoma is associated with altered regulation of the cell cycle. Little

Cyclins play a fundamental role in the cell cycle. Recent studies have focused on their role in the development of various malignancies. The objective of this study was to evaluate and compare the expression of cyclins A and E in common nevi, dysplastic ...

LIN-9 phosphorylation on threonine-96 is required for transcriptional activation of LIN-9 target genes and promotes cell cycle progression. [PDF]
Cell cycle transitions are governed by the timely expression of cyclins, the activating subunits of Cyclin-dependent kinases (Cdks), which are responsible for the inactivation of the pocket proteins.

Asynchronous nuclear division cycles in multinucleated cells [PDF]
Synchronous mitosis is common in multinucleated cells. We analyzed a unique asynchronous nuclear division cycle in a multinucleated filamentous fungus, Ashbya gossypii.
