  2020-11-06

  

  During DNA replication p21 protein binds PCNA, in its role as processivity factor, to stop replication when there is DNA damage, and apparently p21 also binds PCNA when this is in complex with Cyc/CDKs [11]. In plants, KRPs (functional analogs of p21), inhibit kinase activity in CycD/CDKs complexes

  Rat pheochromocytoma PC12 cells have been widely used as a cell system to study intracellular signaling leading to neurite outgrowth. The advantages of using PC12 cells in the CHK studies are the fact that they naturally express the rat form of CHK and the observation that down-regulation of CHK fun

  2020-11-05

  

  Key molecules in the EP1 second messenger signaling cascade that are necessary for potentiation of GluK2/GluK5 were identified. We also identified three GluK5 serines located in a membrane-proximal C-terminal domain that, when mutated to the phosphomimetic aspartate and expressed with GluK2, rendere

  Another question concerns the mechanism of PC reduction during the phosphate starvation response. There are at least three main mechanisms of PC depletion: suppression of PC synthesis due to substrate exhaustion, downregulation of PC synthase expression by suppression of gene transcription or intens

  2020-11-05

  

  Prostaglandins production and some of their possible biological functions have been reported in protozoa, helminths, and fungi organisms, for example amphizoic amoebas of the genus Acanthamoeba and Entamoeba (E. histolytica) produce PGA2, PGE2 and PGF2α [5,6]. PGA2 is believed to be an intrinsic osm

  Additionally, although the membrane-localized ER signaling described in this review has generally been studied in isolation from nuclear signaling, it is becoming clearer and clearer that integration of these mechanisms must be considered (Frick, 2015). Perhaps the distinct estradiol signaling mecha

  Crystallographic and NMR-based analyses have revealed that RINGs and U-boxes have a common mode of interaction with E2s (Fig. 2A). The key structural elements are two loop-like regions, which, in the case of RINGs, coordinate Zn. The loops surround a shallow groove formed by the central α-helix. Tog

  In another study, Nutlin-3a-mediated p53 activation induced strong negative impact on NF-κB signaling in LPS-stimulated neutrophils and macrophages [34]. Nutlin-3a limited cellular immune response to LPS, partly by attenuating DNA binding activity of NF-κB and impairing transcription of its target c

  For example, 200nM MTX markedly stimulates the differentiation of the monocytic U937 A-1210477 [39], but only 10nM MTX is sufficient for the inhibition of clonogenicity in the ALL and APL cell lines [22]. Furthermore, an even lower concentration of MTX (2nM) selectively induces the expression of p2
