  2024-02-23

  

  In addition to pH regulation by ion (counter-) fluxes, acidification is regulated by the abundance of V-ATPase on organelles, by the pumping activity of the complex and by proton leakage. In yeast, the V-ATPase VO subunit a is the only subunit expressed in two isoforms termed Stv1p and Vph1p. V-ATPa

  2024-02-23

  

  Here, we investigate the ATM to ATR switch in normal human fibroblasts (82-6 cells) after irradiation with γ-rays, or high LET 56Fe and 28Si and moderate LET 16O particles. Our data provide important evidence of LET dependence on the transition of ATM to ATR as well as end resection at the sites of

  Conclusion This is the first report to show that treatment of lung cancer cell lines, A549 and H1299, with ovatodiolid stimulates intracellular reactive oxygen species generation and induces DNA damage. Subsequently activates ATM/ATR and CHK1/2 signaling pathway, inhibits CDC25C and p21WAF1/CIP1,

  2024-02-23

  

  The protective role of HMW-HA in inflammatory diseases and pulmonary damage led us to investigate whether PM2.5-induced ALI could be attenuated by HMW-HA and the underlying mechanisms. In this study, we used a rat model to evaluate the effect of HMW-HA on pulmonary histology, lung inflammation, oxid

  2024-02-23

  

  AT2 signaling is distinct to that of AT1 (Kaschina and Unger, 2003). As shown here, opposite to the stimulating effect of AT1 signaling, it inhibits apelin secretion. Activation of AT2 receptor, which is also G-protein coupled, is known to decrease cAMP and cGMP levels by inhibiting adenylyl cyclase

  Antibiotic drug discovery approaches Traditionally, novel Irsogladine were largely discovered by phenotypic screening approaches of various sources of compounds, such as natural products isolated from extracts of soil microbes and semi-synthetic or fully synthetic compound libraries derived from

  Role of AMPK in inflammation signaling Pro-inflammatory cytokines, such as interleukin (IL)-6 and tumor necrosis factor-α (TNF-α), activate Ikβ kinase (IKKβ), which phosphorylates IκBα, triggering the degradation of proteasomal IκB. This liberates active nuclear factor kB (NF-kB) to translocate i

  2024-02-22

  

  AR is an enzyme involved in conversion of glucose into sorbitol using NADPH as a cofactor [46]. This AR polyol pathway generates sorbitol accumulation and NADPH depletion. NADPH participates in detoxification via glutathione (GSH) reductase pathway [47]. Therefore, reduction of NADPH attenuates remo

  Renal fibrosis is regarded as the final common pathway for most forms of progressive renal disease, and mouse UUO is a widely accepted experimental model of renal injury leading to extreme fibrosis localized to the interstitial compartment.

  2024-02-22

  

  The first suggestions that the cleaved intracellular domain of APP, AICD, might transit to the nucleus and hence selectively regulate gene transcription arose from analogies with the Notch receptor signalling system where similar intra-membrane proteolysis occurs [84], [85] and it was later confirme

  The difficulty of characterizing nAChRs in the central nervous system is also exemplified by early observations that nicotine caused no detectable effect when applied on a brain slice and it is only with the focal and high time resolution of more recent experiments that the effects of nicotinic neur

  In many PS 341 α1-AR mediated activation of PLC has been shown to be the downstream process for NA-induced signalling. The activated PLC initiates subsequent signalling by breakdown of PIP2 to IP3 and DAG (Fisher and Agranoff, 1987) and the process continues. To confirm if such mechanism exists in
