  2020-11-28

  

  Except for S-adenosylmethionine (SAM, Fig. 1), sources of endogenous DNA alkylation are not well defined. Other possible sources include nitroso compounds related to the well known mutagen methylnitrosourea which are generated in vitro by nitrosation of cellular amines including amino acids, protein

  2020-11-28

  

  DGKε is not the only DGK isoform that has been associated with p53. It has been shown that DGKζ binds to p53 and modulates its activity in both the cytoplasm and the nucleus [39]. In the cytosol DGKζ promotes the degradation of p53 through the ubiquitin-proteosome system [39], also a likely mechanis

  2020-11-28

  

  In contrast, DGAT1 does not interact with mitochondria and LDs but can form dimers and tetramers [76]. It has been reported that the hydrophilic N-terminal region of DGAT1, which is not required for acyltransferase activity, has the roles in regulating enzyme activity and the formation of dimers and

  2020-11-28

  

  Effect of a C4-C5 double bond — The presence of a double bond at the substrate’s C4-C5 position affects the reactivity of Δ1-KSTDs to varying extent, depending on the enzyme. Most 3-ketosteroids that are converted by Δ1- KSTDs have this double bond. For some Δ1-KSTDs this double bond is even require

  Functionally, all members of the IL-12 family have been annotated along major inflammatory signaling axes but their roles have often weighed on opposing sides of the immunological balance. For instance, IL-12 and IL-23 are classified as pro-inflammatory cytokines [10] as opposed to the rather protec

  Introduction Natural killer (NK) cells have an unique ability to directly lyse transformed, virus-infected or stressed cells without prior sensitization or major histocompatibility complex (MHC) class I restriction [1], [2]. They were initially defined and shown to be important effectors of the i

  2020-11-28

  

  The small GTPase Ran regulates karyopherin–cargo interactions and the directionality of karyopherin-mediated transport. Like other Ras-family GTPases, Ran cycles between GTP- and GDP-bound states, and the two surface loops in Ran, referred to as the switch I and switch II loops, undergo significant

  2020-11-28

  

  Dopamine activity in the PFC and striatum may be antagonistic, meaning that lower levels of dopamine in the striatum tend to correspond to higher levels of dopamine in the PFC and vice versa (Cools and D'Esposito, 2011; Tunbridge et al., 2006). Human PET studies have reported that dopaminergic PFC f

  2020-11-27

  

  Among the different factors that modulate Schwann cell biology, several studies pointed out the role played by neuroactive steroids, in particular progesterone (P4) and its derivatives dihydroprogesterone (DHP) and allopregnanolone (ALLO). Schwann CGS 21680 are steroidogenic, possessing the entire e

  Estrogen receptors activate mGluR signaling pathways In order to distinguish the opposing effects of estradiol on CREB phosphorylation, we turned to a “bottom-up” approach, working backwards from CREB phosphorylation to pharmacologically isolate the two signaling pathways (Boulware et al., 2005).

  We further analyzed the transcriptional mechanisms underlying the synergistic action of IL-23 and PGE2 and found that this action is mediated by not only STAT3 but also CREB1 and NF-κB. Involvement of CREB1 is analogous to that in the PGE2-EP2/EP4–mediated Il12rb2 induction during TH1 cell different

  Acknowledgments Introduction Endothelin receptors Shortly after the discovery of ET‐1, two types of seven transmembrane G protein‐coupled receptors were cloned called endothelin receptor A (ETA) (Arai et al., 1990) and ETB (Sakurai et al., 1990). The affinity of the ETA receptor for ET-3 is
