  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).

  In a recent report, Yoshihara and colleagues (2016) used transcriptomes derived from freshly isolated islets of 2-week-old neonatal, 6-week-old young adult, or 12-week-old adult mice to interrogate how maturation is regulated to acquire glucose responsiveness. The authors observed that estrogen-rela

  ACAT1 may act as a dimer of dimer [38]. Within each dimer, it may contain two identical sterol substrate sites (designated as site S), and one or two sterol activator site(s) (designated as site A). Site S preferentially binds pregnenolone (PREG); it can also bind a variety of sterols that contain 3

  2020-12-02

  

  The UPR is composed of three different pathways that fall under the control of three respective ER transmembrane proteins: PERK, IRE1α (inositol-requiring enzyme 1α) and ATF6 (activating transcription factor 6). As a starting signal for the UPR, misfolded proteins induce the release of GRP78 from th

  The modification of proteins with the small 76-amino phorbol myristate acetate protein ubiquitin (Ub) plays a central role in many key cellular processes. Ubiquitylation of a target protein requires the concerted action of a cascade of three enzymes (Figure 1). The ubiquitin-activating enzyme (E1) c

  Introduction DNA ligation is required during DNA replication and to complete almost all DNA repair events. In human cells, the DNA ligases encoded by three LIG genes are responsible for joining interruptions in the phosphodiester backbone [1]. These enzymes have distinct but overlapping functions

  Our recent discovery (M.P., H.R., A.S.) of a highly selective and in vivo active DDR1 small-molecule inhibitor provides evidence that DDR1 is a druggable pharmaceutical target, and some details of our efforts are provided below. To avoid the repurposing of known kinase inhibitor structural motifs, w

  Arsenic could cause apoptosis in both benign and malignant cells (Akao et al., 2000, Gupta et al., 2003, Namgung and Xia, 2001). However, at present, little is known about the consequences of arsenic-treated urothelial cells in autophagy and expression of its related proteins. In addition, the alter

  ICV injection of UCN2 or UCN 3 performed in the morning of the 8th day (12h after the last IP administration) seems to increase further the time spent in the open arms of mice exposed to saline or nicotine treatment. Interestingly, in mice exposed to saline treatment ICV injection of UCN 2 or UCN 3

  2020-12-01

  

  Two additional hydrogen-bonds are formed by the -substituted methoxy-group with Ser and Asp. Ser exerts the role of a gate keeper in CK1: Entry of the ATP in the binding-site causes a conformational change into the closed form by Ser, which locks the binding-site and prevents ATP-diffusion out of th

  The relatively low overall response rates suggest the need for better predictive markers for response. The patient demographics in the SARC trial did not reflect typical Ewing sarcoma demographics as the patients tended to be older and had primarily soft tissue tumors. In addition, although accrual

  The mechanisms by which Cav-1 enhances embryonal tumor progression are currently unknown. Given the documented ability of Cav-1 to drive increased biogenesis of caveolae and accelerate the flow of nutrients (mostly glucose and fatty acids) across the membrane, as observed in particular in adipocytes

  Which other approaches can complement signaling optogenetics to paint a more complete picture of developmental Erk signaling? For now, the authors have dynamically manipulated Erk signaling but measured the Erk output at steady-state using classic immunofluorescence techniques (Johnson and Toettcher

  In sum, although it is reasonable to assume that the activities of an enzyme on alternative (metabolically available) substrates may often depend on neutral drift, the point is difficult to prove because various types of selective pressures can be at play, and these will be different in different or
