ErbB2 and cell cycle control

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...

Syngamy and Cell Cycle Control

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...

Cell cycle control and cancer

Cancer is a multifaceted disease, but a common feature of most tumours is that they harbour one or more genetic mutations that allow them to proliferate outside their normal growth restraints. Proliferation is normally restrained through control of the cell division cycle, which in turn, is regulated by the Cdk family of serine/threonine kinases and their regulatory partners the cyclins. Here, ...

Cell growth and cell cycle control

Our understanding of the control of cell division has recently advanced through the application of new technologies (e.g., sequencing, cryo–electron microscopy [cryoEM], microfluidics) and crosspollination from different fields (e.g., signal processing and applied mathematics). The success of this approach is demonstrated by the fact that our session hosted not one, but two, ASCB award winners:
