  2023-12-05

  

  Osteoblasts have been thought to be the major cell type that expresses RANKL (Suda et al., 1999) which is a ligand for osteoprotegerin (OPG) and which functions as a key factor for osteoclast differentiation and activation. Recently, Nakashima and his colleagues (Nakashima et al., 2011) demonstrated

  Antioxidative stress and anti-inflammation Oxidative stress is a major cause of reduced endothelial NO bioavailability in hypertension, and inflammatory response is thought to play an important role in these processes (Blake and Ridker, 2001, Landmesser et al., 2006). Reactive oxygen species (ROS

  Several 16-dehidropregnenolone derivatives functionalized at C3, C4, C5 and C6 (Fig. 7) were prepared and evaluated as 5α-reductase inhibitors bearing in mind that after the formation of an enzyme-steroid complex a nucleophilic portion of the enzyme attacks the double bond of the steroid through Mic

  As previously mentioned when hypoxia-treated cells become re-oxygenated they sustain a significant amount of DNA damage which has been attributed to the formation of reactive oxygen species . This finding represents more than just an interesting in vitro phenomenon as within a tumor, cells have been

  Growth-inhibition assays are the most commonly used to identify antifungal small molecules. However, they have several facts that limit their use since many pathogenic fungi grow as filaments making difficult a correlation between growth and OD (optical density). They are not useful for identifying

  There are several reports providing evidences that functional and mechanistic connection between Sirt1 and LKB1/AMPK in metabolic regulation [26], [32], [33]. It has been reported that the deacetylation of LKB1 by Sirt1 is one of the determining factors of the subcellular localization of LKB1. In ag

  In addition, AMPK reduces protein synthesis and stimulates apoptotic and autophagic pathways through the inhibition of the mechanistic target of rapamycin (mTOR), which regulates cellular metabolic homeostasis, insulin secretion, insulin resistance, autophagy and apoptosis (Maiese, 2016). mTOR is th

  HIF-1α HIF-1α signaling in cancer cells contributes to tumor progression by promoting angiogenesis, invasion, metastasis, and the recruitment of immunosuppressive cells via secreted modulators 36, 37. One example of a HIF-1α immunosuppressive pathway is through increased expression of inducible n

  The importance of insulin in controlling lipolysis and fat mass is further emphasized by mouse models with alterations in the insulin signaling pathway of adipocytes. For example, mice with a tamoxifen-inducible knockout of the insulin receptor in mature adipocytes reveal a substantial decrease of a

  The AChR is composed of five homologous, membrane-spanning subunits. AChRs containing two α, one β, one δ and one γ subunit (AChRγ) predominate during embryonic development and mice lacking AChRγ die at birth (Takahashi et al., 2002). After birth, the AChRγs are replaced during the first 2 postnatal

  The structure of 5-LO is divided in two domains, the catalytic C-terminal domain and the N-terminal regulatory C2-like domain (C2ld) [59,60]. The C2ld spans the 2-Deoxycytidine 1-114 and is responsible for translocation and binding of calcium and membranes [61–63]. The catalytic domain is primarily
