The transition from mitosis (M phase) to G1 phase is controlled by complex interactions between two key components of the cell-cycle machinery, the anaphase-promoting complex or cyclosome (APC/C) and cyclin A. The APC/C is a multisubunit ubiquitin ligase that controls sister-chromatid ...
Whi3 binds the mRNA of the G1 cyclin CLN3 to modulate cell fate in budding yeast Eukaryotic cells commit in G1 to a new mitotic cycle or to diverse differentiation processes. Here we show that Whi3 is a negative regulator of , a G1 that... E Garí,T Volpe,HY Wang,... - 《Gene...

While, the loss is evaluated using a quasi-Newtonian approach and the gradients are evaluated using finite difference. In Lagaris et al [89], the solution of a differential equation is expressed as a constant term and an adjustable term with unknown parameters, the best parameter values are ...
molecules. Although the pathway of hapten-specific T-cell activation is now well established, several questions need to be addressed: first, what is the nature of the hapten-modified peptides displayed by MHC? Second, how many of these peptides stimulate T-cells?; third, what are the ...
However, while it is clear that EAC originates from glandular cells near the stomach, BE consists of many cell types, and thus it remains uncertain which cells are the main drivers of EAC. In contrast, ESCC is derived from squamous epithelial cells and appears to be driven by carcinogenic ...
