New evidence is also presented whereby starving plant cells of sucrose did not affect expression of Rb which would be consistent with an arrest of those cells in G1 in these conditions. Dynamin -related proteins are important at cytokinesis, and recent evidence suggests that one subset plays a ...
DNA damage or other senescence-inducing stimuli induce cell cycle arrest through the activation of thep53/p21CIP1orp16INK4A/phospho-Rbtumor suppressor pathways. These cascades induce senescence by inhibiting kinases associated with cell cycle progression and blocking the transcription of proliferation prom...

The magnetic cycle is believed to be caused by a magnetohydrodynamic (MHD) dynamo process in the solar interior, where the flows and the magnetic fields interact in the strongly turbulent convective zone. The intrinsic features of the solar interior, e.g., the stratification, the turbulence and...
The probable initiating molecular events are inactivation of TP53 and RB1, as well as frequent disruption of several signalling networks, including Notch signalling. SCLC, when diagnosed, is usually widely metastatic and initially responds to cytotoxic therapy but nearly always rapidly relapses with ...
In addition, signal transducer and activator of transcription 3 (STAT3) is activated. The collective impact favors an increase in cell metabolism, cell cycle progression, and a decreased sensitivity to apoptosis. (b) Cell signaling in 'wild-type' gastrointestinal stromal tumors (GISTs). Mutations ...

A deeper understanding of the role of autophagy, literally ‘self-eating’, in normal and cancer cell biology has emerged over the last few years. Autophagy serves as a vehicle for cells to respond to various stressors including genomic, hypoxic and nutr
Conjugative plasmids employ proteins encoded on the leading region to antagonize defense systems in the recipient cell. The backbone of a generic CP is composed of thetraregion that encodes all proteins necessary in conjugal transfer (green); the origin of transferoriT(red); the leading region (...
