  2021-01-11

  

  While oxysterols were most extensively studied for its potent ability to mediate feedback regulation of cholesterol biosynthesis, some early investigations showed that the enzymes involved in its syntheses were highly upregulated in macrophages and dendritic cells—an indication of possible roles in

  Concholepas concholepas, our model species for this study, is a marine gastropod found along the Chilean coast that has become commercially important [25], [26], [27]. Until now, the main focus of immunology related to C. concholepas is the production of a novel hemocyanin that has been useful for t

  The repair pathway of DNA-DSBs through HR and the role of BRCA1 in repair kinetics by HR is also an important factor to unravel the radiation sensitization of novel small molecule inhibitors. The involvement of the breast cancer susceptibility gene 1 (BRCA1) in tumorigenesis and its role in facilita

  2021-01-09

  

  Given the structural similarity of BMAA to other amino acids, our hypothesis was that N-nitrosation of BMAA might result in a toxic alkylating agent, providing a previously unrecognised mechanism for BMAA action. Materials and methods Results and discussion We first examined whether chemical

  2021-01-09

  

  Bovine collagen type II, a fibrillar collagen mainly found in cartilage, comprises 24 potentially glycosylated lysine residues within its collagen domain. Detailed analysis revealed that 22 out of 23 of these lysine residues are hydroxylated and carry variable numbers of Gal(β1-O) and Glc(α1-2)Gal(β

  2021-01-09

  

  Trk receptors critically support the development and maintenance of the nervous system, , but their over-expression in various neural and non-neural neoplasms such as breast, pancreatic, lung and neuroendocrine tumors also confers aggressive phenotypes to tumor calcium sensing receptor and correla

  2021-01-09

  

  ClC-3 is not only a chloride ion channel but also a regulatory protein involved in the regulation of multiple signaling pathways. The PI3K/AKT/mTOR signaling pathway plays a crucial role in regulating cell growth, migration, invasion, and distant metastasis [13,14]. Although abnormal PI3K/AKT/mTOR a

  2021-01-09

  

  Thus, the exact mechanisms responsible for progestogen-induced changes in immune response are not known but the effects are believed to be exerted through receptor-mediated interactions. Since the mPR α is known to be a G protein-coupled receptor in fish, downstream signaling cascades via secondary

  Thus, the understanding of the various mechanisms of action of estrogen and SERMs is an important medical challenge and could help to develop an “ideal” SERM, preserving the beneficial effects of estrogen in the bone and urogenital system, and reducing the unwanted side effects, mainly increased ris

  We found all cases to show at least some IGF-1R expression by immunohistochemistry. This is consistent with its ubiquity at the mRNA or protein level in ES/PNET cell lines or clinical samples as shown by others.12, 14 Evidence that IGF-1R expression is required for EWS-FLI1 transformation of mouse f

  2021-01-09

  

  The reaction of chitosan with DVS should take place primarily through a nucleophilic attack of the vinyl sulfone groups to the amino groups in chitosan [39,50], although its hydroxyl groups can also be involved, as it happens when using agarose [35]. These reactions create very stable secondary amin

  Our approach, including the characterization of histone modifications in scarce NK subsets, allowed us to identify super-enhancers, which associate with genes endowing a given cell type with its unique identity (Hnisz et al., 2013). Especially intriguing were SEs with distinct activities in NK subse

  Significance Our understanding of the ubiquitin biology has been rapidly expanding. The role of the ubiquitin system in the pathogenesis of numerous disease states has increased the interest in finding new strategies to pharmacologically interfere with the enzymes responsible of the ubiquitinatio

  The quaternary structure of many of the family B members (i.e., secretin, glucagon, glucagon-like peptide and Liproxstatin-1 receptors) have been actively studied and it has been demonstrated that they can form homodimers/oligomers (Gao et al., 2009; Ng & Chow, 2015; Ng, Lee, & Chow, 2013).

  Enzymes involved in microbial steroid degradation are generally not expressed constitutively, but they are upregulated depending on which steroid substrates are present [17,81]. Thus, a cell-free extract prepared from testosterone-adapted C. testosteroni ATCC 11996 cells displayed a 1(2)-dehydroge
