  2020-10-26

  

  Collagen type 1 is the most abundant extracellular matrix (ECM) protein found in vertebrates. Collagen exerts its role as a load bearing structure and regulator of cell function, only after it has assembled into fibrils., The equilibrium between the synthesis and degradation of collagen fibrils and

  2020-10-26

  

  What are the molecular signals that guide Tfh cells as they navigate around the lymph node in the course of the immune response? It was recently reported that Tfh cells inside GCs have high expression of SIPR2, which acts to repel them from the S1P-rich lymph in the SCS and promote their retention i

  2020-10-26

  

  Our finding that one enzyme acts both as a primase and a DNAP poses evolutionary and mechanistic questions. In particular, why do cellular organisms require two enzymes to fulfill de novo DNA synthesis? The inability of cellular replicases to perform as primases might be dictated by the challenges a

  2020-10-26

  

  The IP3R is a ubiquitously expressed Ca2+-release channel from the ER, activated by IP3, produced upon cellular stimulation by hormones, growth factors or neurotransmitters. Three genes are coding for the IP3R and their gene products (IP3R1, IP3R2, IP3R3) assemble in functional homo- or heterotetram

  The underlying mechanisms of how progesterone prolongs pregnancy, although not completely understood, are thought to have to do with reduction in uterine contractility, antimicrobial protein up-regulation, immunosuppression, and inflammatory inhibition. Specific to preterm PROM, progesterone has bee

  2020-10-23

  

  Angiomatoid fibrous histiocytoma (originally described as angiomatoid malignant fibrous histiocytoma) is a soft tissue tumor of intermediate biologic potential. AFH typically arises within extremity deep dermis and subcutis in children and young adults,157, 158, 159 but can arise in older adults and

  2020-10-23

  

  Nitrid oxide (NO) and its potential endogenous production as an endothelium-derived factor was the first gaseous molecule accepted to be a signaling mediator in the organism [4,5]. NO plays a key role in physiological regulation of the pterostilbene and exerts physiological functions in the nervous

  2020-10-23

  

  Introduction Mammalian proteases comprise both the peptidases or exopeptidases, which act at the N- or C-terminal positions of polypeptides, and proteinases or endopeptidases, which are capable of cleaving peptide bonds in the central regions of polypeptides. The endopeptidases are classified in

  2020-10-23

  

  The ability of minor groove binding agents to inhibit the activity of DNA helicases is not without precedence. Similar effective inhibition of the unwinding of DNA by the BLM and Werner\'s DNA helicases by the minor groove binder distamycin A has been observed. Further, and similar to RecBCD, interc

  2020-10-23

  

  QSAR based on the 3D structures of ligands plays an important role in the ligand-based drug discovery and design [12]. Comparative molecular field analysis, CoMFA [11], and comparative molecular similarity index analysis, CoMSIA [12] are among the most popular QSAR models. They focus on changes in 3

  2020-10-23

  

  A number of studies have been carried out to understand lipid production pathways and to increase TAGs level in higher plants. Overexpression of key GDC-0834 of the Kennedy pathway until now is by far the most successful strategy to increase TAG lipid content in Brassica napus, Arabidopsis thaliana

  Aspergillus nigerA. niger is another filamentous fungus, in which alternative dehydrogenases have been described. Filamentous fungi are a very important group of microorganisms that are used in industry (O’Donnell et al. 2011). Biotechnological production processes using these organisms are often hi

  2020-10-23

  

  In the cytoplasm, the ternary CRM1–cargo–RanGTP complex is disassembled by the action of Ran-binding proteins RanBP1/2 and RanGAP. A recent kinetic study showed that the Ran-binding domains (RanBDs) of the cytoplasmic proteins RanBP1 and RanBP2, but not RanGAP, accelerate dissociation of NES from CR

  2020-10-22

  

  Ubiquitination and deubiquitination pathways Ubiquitination is a part of the post-translational modification (PTM) process. Ubiquitination affects proteins in various ways, but its main functions are to signal protein degradation via the 26S proteasome, modify cellular location of proteins, affec

  These data from developing guanylate cyclase are in contrast to noradrenergic receptor regulation in the adult brain. In adult animals, a persistent increase in the α2-AR high affinity state is elicited as a result of DSP-4 lesion or reserpinization, as measured by [3H]clonidine binding to membrane
