  2021-07-07

  

  DNA-PK (Jackson, 1997) is activated by DNA double-stranded breaks (DSBs). It is a trimeric complex composed of the catalytic subunit, DNA-PKcs, and the Ku70/80 heterodimer. DNA-PK mediates non-homologous end joining (NHEJ), which joins programmed DSBs created during V(D)J recombination and class swi

  2021-07-07

  

  The most significant source of DAG originates from the PLC family of enzymes, which produces DAG in an agonist-regulated reaction. PLCs constitute a wide family of enzymes acting on both phosphatidilinositols (PI) and phosphatidilcoline (PC) (Li et al., 2010) in the plasma membrane and other intrace

  To compare glucose metabolism via oxidative phosphorylation to that via glycolysis, a bioenergetics plot was constructed (Fig. 3A). In most cells, a decrease in one bioenergetics pathway is compensated by an increase in the other. However, following NAT1 deletion, there was a decrease in both oxidat

  A surprising second functional effect was found in culture experiments. Inclusion of LTD4 reduced the frequency of Fas receptor (CD95) expression. Once again, this effect, although modest, was reversed by a cysLT1 receptor antagonist. The biologic significance of this effect or its mechanism remaine

  The data presented above clearly indicate an important role of eIF4E for the nucleocytoplasmic transport of the human iNOS mRNA. To analyze the sequence elements of the iNOS mRNA that are important for this eIF4E-mediated transport we performed transient transfection experiments using constructs con

  2021-07-07

  

  More recently, it was discovered that BChE hydrolyzes the neuropeptide gut hormone, ghrelin [25], [26], [27], [28]. Nonetheless, because the enzyme reaction is very slow, those who first reported this finding were initially reluctant to attribute a real physiological role for that phenomenon. Our ow

  2021-07-07

  

  ClC-3 is a member of the voltage-gated chloride channel superfamily and has many roles in cell proliferation, apoptosis, Calcium Gluceptate receptor progression and so on (Dai et al., 2005). A growing number of studies showed that ClC-3 encoded a volume-regulated Cl− channel (ICl,Vol) in heart, tha

  2021-07-07

  

  Our earlier experimental studies showed "neutral", i.e. non-proliferative, effects of progesterone but a large increase in proliferation using certain progestins; however, this was only in the presence of PGRMC1 [[13], [14], [15], [16], [17], [18], [19]]. The next step was to investigate whether thi

  2021-07-07

  

  It has previously been shown that human melanocytes are responsive to a multiplicity of hormonal triggers [10], particularly to pituitary or ovarian hormones [11]. Studies concerning the effects of Eplerenone receptor on human melanocytes led to inconsistent data [12], [13]. Im et al. [14] reported

  The effects of the endocrine active agents on hepatic ERα were varied. Both nonylphenol and genistein caused an increase in hepatic ERα in female rats, whereas EE2 did not. It is doubtful that the small changes in hepatic ERα induced by genistein and nonylphenol in female rats are sufficient to alte

  Materials and Methods Results Discussion ROS generated by SFN target many signaling pathways involved in initiating cancer cell death (Sestili and Fimognari, 2015). For example, ROS have been shown to activate both intrinsic and extrinsic caspase cascades in prostate cancer cells (Singh et

  A structural explanation for how RBR RING1s handle their bound E2~Ubs differently from canonical RINGs has not been readily apparent. Only a few residue positions are strongly conserved in RING and RING1 domains, most of which are zinc-coordinating Cys and histidine residues. A key position in canon

  Another example of negative regulation is the inhibition of the yeast endosome-associated DUB Doa4 by Rfu1 (free ubiquitin chains 1). In a yeast genetics screen, deletion of Rfu1 was serendipitously found to alter global ubiquitin levels [69]. DUBs can regulate these levels by liberating conjugated

  Our ex vivo analysis demonstrates that IL-15 promotes CD122 expression in DGKζ-deficient CD8+ T cells. CD122, which forms a dimer with CD132 in response to IL-2 or IL-15, activates the JAK/STAT and PI3K/mTOR pathways. Whereas antigen-stimulated new product promote IL-2 sensitivity through up-regula

  Results Discussion Repair by NHEJ implicitly requires the pairing together of broken chromosome ends. A complex of Ku, XRCC4, DNA ligase IV, and XLF (PEC) is necessary and sufficient for this purpose (Reid et al., 2015). Here, we describe dynamic changes in this complex that are triggered by d
