WebChemotaxis proteins encoded in the same cluster as ParC have a similar unipolar-to-bipolar transition; however, they reach the new pole after the arrival of ParC. Cells lacking ParC exhibit aberrantly localized foci of chemotaxis proteins, reduced chemotaxis, and altered motility, which likely accounts for their enhanced colonization of the proximal small … WebPhosphoinositide 3-kinases (PI3Ks) are a family of lipid kinases that phosphorylate the 3' OH position of the inositol ring of phosphoinositides on the inner leaf of the plasma membrane. Receptor-mediated activation of the PI3K pathway plays a crucial role in numerous signaling pathways and regulate …
WebChemotaxis is an important virulence factor in some enteric pathogens, and it is involved in the pathogenesis and colonization of the host. However, there is limited knowledge regarding the environmental signals that promote chemotactic behavior and the sensing of these signals by chemoreceptors. To … Web12 Apr 2024 · It is generally believed that histone deacetylase (HDAC) inhibitors, which represent a new class of anticancer agents, exert their antitumor activity by directly causing cell-cycle arrest and apoptosis of tumor cells.
