  2021-12-29

  

  Typically, upon chronic agonist exposure GPCRs undergo desensitization and internalization resulting in a loss of receptor responsiveness over time (Drake et al., 2006, Kelly et al., 2008). However, not all GPCR systems conform to this model of acute agonist-mediated regulation. Some receptors have

  Introduction Lichen-forming fungi (LFFs) have evolved in various classes, including Arthoniomycetes, Coniocybomycetes, Dothideomycetes, Eurotiomycetes, Lecanoromycetes, Leotiomycetes and Lichinomycetes, in Ascomycota (James et al., 2006, Schoch et al., 2009a, Lumbsch and Rikkinen, 2017, Prieto et

  Hepatic drug-metabolizing protease inhibitor cocktail and transporters expression were regulated by nuclear receptors [19], [20], [21]. The effects of HFD-induced fatty liver on drug metabolizing enzymes in mice were recently studied, and the results provided a systematic evaluation of the changes

  2021-12-28

  

  The ability of GPX4 and other selenoproteins to be selectively induced by ferroptotic stimuli suggests that the stress-induced increase in the transcription of a number of putative, “antioxidant” selenoproteins is an adaptive homeostatic, but insufficient response to prevent cell death in the face o

  Our data show that oxidative stress (high levels of ROS) suppresses the process of lysosomal exocytosis, which would be predicted to impair the expulsion of toxic compounds from cells. Therefore, we propose that ROS have a biphasic effect on the lysosomal clearance: consistent with their role as a s

  However, HDACi can also increase the acetylation of other transcription factors that regulate p65 transcriptional activity. The HDACi-induced activation of p65 can be negated by acetylated STAT1, which can specifically bind to p65 and inhibit its transcriptional activity 81, 82, 83. Interestingly, a

  2021-12-28

  

  HBV is an enveloped, double-stranded DNA virus, which is transcripted into four major transcripts [6]. Among them, the 3.5 kb pregenomic RNA (pgRNA) directs the translation of HBV polymerase, core protein and acts as template for reverse transcription. So viral transcription is a key step of virus l

  GPR55 GPR55 has been described as a type 3 cannabinoid receptor due to its ability to detect endocannabinoids and may play a role in the endocannabinoid lipid sensing system [28]. GPR55 is activated by both cannabinoid endogenous agoinsts (endocannabinoids) and non-cannabinoids fatty acids namely

  Gene expression of both GPR109A and GPR81 in adipocytes has been linked to PPARγ activation [22]. Treatment with the thiazolidinedione (TZD) PPARγ agonist, rosiglitazone, increases GPR109A and GPR81 expression, and knockdown of PPARγ suppresses receptor expression in fully differentiated human multi

  Based on the role of NMDA receptors in initiation and propagation of epileptic seizures and on potentiation of NMDA function by glycine, it has been hypothesized that glycine will have proconvulsant activity (Foster and Kemp, 1989). Indeed, there is some evidence that human epileptogenic foci, remov
