Syngamy and Cell Cycle Control

Cell cycle control of BRCA2.

Identifying the conditions and kinetics of the induction of BRCA2 gene expression may implicate roles for the function of the tumor suppressor gene. In this study, expression of BRCA2 mRNA is shown to be regulated by the cell cycle and associated with proliferation in normal and tumor-derived breast epithelial cells. Cells arrested in G(0) or early G1 contained low levels of BRCA2 mRNA. After r...

Cell Cycle: Principles of Control

tion at the end of each case. For students desiring a more in-depth review, the analysis section of each case provides a great and more detailed overview. An extra index organized by disorder name in the back also allows the reader to focus on particular aspects of internal medicine. Details such as this make it obvious that the authors have tried to cater to the varying needs of their readers,...

Adenovirus and cell cycle control.

Adenovirus infection of quiescent cells induces transition from G0 or G1 into the S phase of the cell cycle and allows cellular proliferation. This is beneficial for the virus since cells in S phase provide optimal conditions for viral replication. Adenovirus E1A, E1B and E4 gene products contribute to cell cycle deregulation. E1A proteins inactivate the pRb checkpoint, allowing the E2F transcr...

Calcium and cell cycle control.

The cell division cycle of the early sea urchin embryo is basic. Nonetheless, it has control points in common with the yeast and mammalian cell cycles, at START, mitosis ENTRY and mitosis EXIT. Progression through each control point in sea urchins is triggered by transient increases in intracellular free calcium. The Cai transients control cell cycle progression by translational and post-transl...
