  2024-11-19

  

  How does the ATM-to-ATR switch occur at DSBs? The progressive attenuation of ATM activation could be attributed to the loss of DNA structures that activate ATM, or to the generation of DNA structures that interfere with ATM activation. Our finding that SSOs do not directly affect the binding of pur

• The downstream targets of ATR involved

  2024-11-19

  

  The downstream targets of ATR involved in mediating human telomerase recruitment have not yet been identified. Under stalled fork conditions, activated ATR is able to phosphorylate and activate ATM (Stiff et al., 2006, and Figures 4C and 4D); whether this Deoxycholic acid of ATM participates in a p

  2024-11-19

  

  The canonical bafilomycin a1 receptor to which α2, α3, or α5 contribute are highly similar. Therefore, differences in ligand affinity will not be large even if a ligand makes optimal use of the small differences in the pockets. As a possible alternative approach to achieve separation of compound ef

  2024-11-19

  

  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

  2024-11-19

  

  Cerebral ischemia occurs following the occlusion of a cerebral artery by a thrombus and causes cell swelling due to cytotoxic edema and BBB disruption with vasogenic edema (Loreto and Reggio, 2010, Nakaji et al., 2006, Shibata et al., 2004). Vasogenic edema is directly linked to alteration of the BB

• Placental cells also express P aromatase CYP

  2024-11-19

  

  Placental cells also express P450 aromatase (CYP19A1, encoded by CYP19A1). In the placenta, this enzyme requires an external source of androgens, provided by the adrenal gland of the fetus, to form estrogen. The fetal adrenal gland produces dehydroepiandrosterone (DHEA) [9] and, in the placenta, it

  2024-11-19

  

  Enhanced arginase activity and the resultant decreases in L-arginine levels can also impair T cell mediated immune function and allow tumor growth by limiting the supply of L-arginine needed for the formation of cytotoxic levels of NO by iNOS [10]. Increased arginase expression/activity may also lim

• Apelin is a peptide hormone and

  2024-11-19

  

  Apelin is a peptide hormone and an endogenous ligand for a G protein-coupled receptor named APJ [7], [8], and apelin and APJ are widely expressed in human organs including hypothalamus, heart, lungs, kidneys, adipose tissue, muscles, and others [9]. Apelin is initially synthesized as a 77-amino-acid

• There are several AP binding

  2024-11-19

  

  There are several AP-1 NLG919 in the sequence of TIMP-1 promoter [18,19]. EBV could up-regulate TIMP-1 expression by binding to the AP-1 site in the TIMP-1 promoter [18]. IL-32, a newly multi-function cytokine, could activate AP-1, NF-κβ, p38MAPK signal pathways, and induce cytokine expressions, su

  2024-11-19

  

  HMGN proteins are subject to extensive post-translational modifications which influence both their mode of binding to 3'-O-(2-nitrobenzyl)-2'-dATP and their functional activity. Like the other HMG protein families, HMGNs are substrates for many of the same enzymes that modify histone proteins (revi

  HMGB proteins and chromatin structure The multifaceted roles played by HMGB (formerly called HMG-1 and -2) proteins in modulating chromatin structure, gene transcriptional activity and cellular phenotype have been covered in a number of recent reviews and readers are referred to these for in-dept

  2024-11-19

  

  Cellular detoxification is an important process that helps remove excess oxidants from the cellular environment through endogenous antioxidants or other molecules capable of reduction. One of the key regulators of antioxidant production is the transcription factor, nuclear factor (erythroid-derived

  2024-11-18

  

  Phytoremediation technology is defined as the use of plants to remove contaminants from soils or to render them harmless, and is regarded as a cost-effective, environmental-friendly method for reclaiming soils contaminated by toxic metals (Lasat, 2002, Mahar et al., 2016, Marrugo-Negrete et al., 201

  In summary, the different types of interstitial cells found in the current study are illustrated in Fig. 7A (see legend for further details), which is suggestive of a heterogeneous complex network of interstitial cells communicating with each other. The possible signaling pathways involving this int
