  2024-10-28

  

  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

  2024-10-28

  

  Earlier studies showed that exposure of cells to IR caused ATM-dependent phosphorylation of 53BP1, as judged by electrophoretic mobility shift [24], [25], [26]. To date, the only known in vivo 53BP1 phosphorylation site(s) are Ser25 and possibly Ser29 [27]. In the course of our studies, we noticed t

  2024-10-28

  

  Aromatase: the key enzyme for estrogen formation in adipose tissue Estrogens are synthesized from androgens by aromatase, a member of the cytochrome P450 superfamily, which is the rate-limiting enzyme in estrogen biosynthesis (Santen et al, 2009, Simpson et al, 1994). At the cellular level, aroma

  It has been demonstrated that the hallmarks of pulmonary fibrosis are a loss of endothelial function and subsequent activation of the immune system, which is considered as a direct outcome affected by intracellular pro-inflammatory responses [26]. Thus, inhibition of early inflammation could be an i

  Thiazole heterocycles constitute an interesting class of molecules, which exhibit a broad spectrum of biological activity, including antifungal properties [[16], [17], [18], [19]]. Encouraged by our previous study that describes the activity of hydrazine-thiazole derivatives against C. gattii and C.

  2024-10-26

  

  Sorafenib was the first small RTK inhibitor drug to be developed and was initially approved against renal cell carcinoma, then against hepatocellular carcinoma (HCC) and more recently for differentiated thyroid treatment [111]. Sunitinib soon followed, being approved for gastrointestinal stromal tum

• Expression of Twist and the AR

  2024-10-26

  

  Expression of Twist1 and the AR are increased by oxidative stress, but the change in the receptor (mRNA/protein) is lost after treatment with siRNAs that target Twist 1 (Shiota et al., 2010). Twist 1 was found to bind to E-boxes, 5′-CANNTG-3′, in the proximal promoter (−442 to +51 bp) and upstream r

  Aβ and tau in Alzheimer's disease The two classical histopathological hallmarks of AD are extracellular insoluble Aβ deposits, known as Aβ plaques, and intracellular accumulations of insoluble microtubule-associated tau protein, known as neurofibrillary tangles [14]. Aβ peptides are produced as a

  Mass spectrometry (MS) analysis and selective enrichment methods of phosphorylated proteins are powerful tools that can help address these challenges. Recent advances in MS have made it possible to analyze signaling pathways by facilitating high-throughput identification of phosphorylation sites wit

  2024-10-26

  

  Some alterations in the integrity of cell membranes caused by toxic agents can be determined by measuring certain enzymes released by damaged cells [8]. The cholinesterases, for example, catalyze the hydrolysis of imidazole (ACh) in choline and acetic acid. Theses enzymes are divided into two types:

  2024-10-26

  

  Osteocytes, the most abundant cells in an adult skeleton, are essentially mature osteoblasts that are surrounded by the products they secreted (Noble and Reeve, 2000). Osteocytes serve as mechanosensors that direct bone remodeling and that regulate the activities of osteoblasts and osteoclasts (Bone

  It has been shown that ACLY is localized to not only the cytoplasm but also the nucleus. Nuclear ACLY may supply acetyl-CoA for histone acetylation, leading to global regulation of the gene expression [16], [18]. We previously reported that AZ2 is also localized to both the cytoplasm and nucleus whe

  The uterine muscle also changes to meet the demands of pregnancy. Over the course of pregnancy, the myometrium undergoes structural remodeling to accommodate a growing fetus, followed by a functional switch from quiescent to contractile characteristics for parturition. Studies on the mouse model ind

  A different mechanism has been suggested for the role of TRX1 in ASK1 regulation based on disulfide bond-mediated ASK1 multimerization and its reduction through the thiol-reductase activity of TRX1 (Nadeau et al., 2007, Nadeau et al., 2009). In this model, oxidative stress induces intermolecular dis
