  Other membrane currents are affected as well. Some studies have provided evidence that sulfonylureas, in addition to blocking KATP channels, also inhibit chloride and calcium channels. GLYB has been shown to almost inhibit the current generated by Na+–K+ pumps in a concentration-dependent manner (wi

  MdHCLB channels expressed in Xenopus oocytes produced currents in response to HA and GABA (Fig. 1, Fig. 3). This is in agreement with the findings with Drosophila HCLB channels (Gisselmann et al., 2004). In the HA concentration-response curves, the effects of GABA were additive to those of HA only i

  Introduction The physiological significance of hypoxia is undisputed, although largely over looked in the cancer therapeutics field focused on DNA-damage induced by ionizing radiation or drug treatment. Regions of hypoxia occur during a range of diverse biological situations including embryogenesis

  Nuclear estrogen receptors: Indirect genomic signaling As mentioned earlier, the transcription of several genes that do not contain EREs in their promoter regions can also be regulated by estradiol, without direct binding of the estrogen receptors to the DNA. According to the most recent reports,

  Tinnitus Met carriers with severe hearing loss perceive their tinnitus as being louder, which is associated with increased activity in the PHC, increased PHC→pgACC connectivity, as well as decreased pgACC→PHC connectivity. This indicates that Met carriers with severe hearing loss have increased tinn

  Among RAS mutant tumors analyzed, we found that the efficacy of either the SHP2 inhibitor SHP099, or combined MEK and SHP2 inhibition was best in those expressing RAS mutations at G12 (Figure 7B). Recent studies revealed that cellular RAS(G12C) activity depends on RTK-mediated nucleotide exchange, a

  Although information regarding the influence of PGE2 on cardiac fibroblast cell growth is sparse, the effect of PGE2 on other cell types has been studied extensively, particularly in cancer and cancer cell lines where COX-2 is over-expressed. Constitutive high levels of COX-2 expression have been no

  Expression of both CH25H and CYP7B1 by lymphoid stromal Z-YVAD-FMK is required for the synthesis of 7α,25-OHC in lymphoid tissues and the correct positioning of B cells. Production of EBI2 ligand by hematopoietically derived cells appears limited [24] but may occur under some circumstances, given th

  Two primary members of the TRIM family – TRIM5α and TRIM25 – function as antiviral effector and immune regulator, respectively. TRIM5α is one of the best characterized members of the TRIM family (both structurally and functionally) and reported to be an important ubiquitin-mediated regulator of a ma

  Since the initial identification of DNA ligase inhibitors by a structure-based approach [[18], [26]], there have been several reports describing LigI inhibitors using computer modelling and derivatives of the original DNA ligase inhibitors [[49], [50], [51]]. While these studies have shown that the

  The first example of a broadly-acting antiviral drug is ribavirin, a nucleoside analogue that was proposed to act directly at the level of the viral polymerase, although an indirect effect via inhibition of the host-cell IMP dehydrogenase and depletion of the GTP pool seems more plausible [9].
