  In the present work, we ask whether rNMP incorporation is an evolutionarily conserved property of DNA synthesis in Archaea. For this purpose, we used the best characterized hyperthermophilic anaerobe, Pyrococcus abyssi GE5 [47]. This strain duplicates its genome as fast as Bacteria, supported by euk

  Genomic and non-genomic signaling crosstalk As exemplified in the previous sections, it is evident that the mechanisms of action of estrogen in the various cell targets represent a combination of complex multifactorial processes. Besides the independent genomic and non-genomic pathways described

  The mechanism by which OC use leads to impaired glucose tolerance is yet to be fully clarified. Decreased insulin sensitivity appears to be mainly accounted for by estrogenic component and this effect may be modified by progestogenic component [14], [15]. Estrogenic effect on glucose tolerance has b

  Acknowledgements Introduction α-L-Rhamnosidases (EC 3.2.1.40) are glycosyl hydrolases (GHs) that cleave terminal α-l-rhamnose from a large number of natural products [1]. The action of α-L-rhamnosidases (α-RHAs) has been reported, among others, on different complex substrates such as heteropol

  2021-01-05

  

  One possible pitfall of using EPAC2 activators in the treatment of T2DM is their potential to increase glucagon levels. As discussed previously, although the ability of EPAC2 to increase glucagon expression and production is controversial, several studies show that this protein increases Gcg mRNA le

  2021-01-05

  

  In addition to vasoconstrictor actions (acute effects), ET-1 exerts potent mitogenic actions on vascular smooth muscle cells and cardiac myocytes (chronic effects), hence causing vascular and cardiac hypertrophy [19,24,25]. These effects are mediated via stimulation of either ETA or ETB receptors, a

  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

  2021-01-05

  

  Protein deubiquitination is becoming increasingly instrumental in understanding the complexities of the Ub system. Adding to this complexity is the discovery of bacterial effectors with DUB activity that have structurally adapted themselves to interfere with the eukaryotic Ub system (Pruneda et al.,

  The changes in the chemokine receptors CCR-5 and CXCR-4 in women and men with PTSD are completely different. In the group of women with PTSD alone the level of this Y-27632 increased six times, whereas, in women with APD and PTSD, the level of the receptor CCR-5 was eight times higher than in the c

  COMT expression, protein level and activity are down regulated by E2. Using estrogen receptor (ER) positive MCF-7 cells, Xie et al. demonstrated an E2 dose dependent (1, 10 and 100 nM) decrease in S-COMT 1.3 kb mRNA that was maximum after 48 h (Xie et al., 1999). A similar decrease was not observed

  To avoid the difficulty of the nonsmooth constraints, a sequence of smooth problems by using smoothing functions have been progressively approximated this nonsmooth problem. To date, there have been many smoothing functions, such as perturbed Fischer–Burmeister (FB), Chen–Harker–Kanzow–Smale (CHKS),
