Nitric oxide (NO)-induced relaxation is associated with increased levels of cGMP in vascular smooth muscle cells. However, the mechanism by which cGMP causes relaxation is unknown. This study tested the hypothesis that activation of Ca-sensitive K (KCa) channels, mediated by a cGMP-dependent protein kinase, is responsible for the relaxation occurring in response to cGMP. In rat pulmonary artery...
Chromatin relaxation is one of the earliest cellular responses to DNA damage. However, what determines these structural changes, including their ATP requirement, is not well understood. Using live-cell imaging and laser microirradiation to induce DNA lesions, we show that the local chromatin relaxation at DNA damage sites is regulated by PARP1 enzymatic activity. We also report that H1 is mobil...
Nucleoside reverse transcriptase inhibitors (NRTIs) have been used successfully to reduce acquired immunodeficiency syndrome mortality. However, the use of these compounds is associated with numerous tissue toxicities, including cardiomyopathy. These studies address the effects of NRTIs on vascular function. Functional assays of contraction and relaxation were performed on isolated mouse aorta ...
The anomalous transport of particles in the presence a time-dependent field is considered framework comb model. This turbulent-like dynamics consists inhomogeneous advection along x-backbone and Brownian motion y-side branches. geometrically constrained leads to diffusion backbone, which described by fractional equation with coefficients. time periodic process localization particular form relax...
