  PGE2 exerts its functions by binding to different receptors. Four different subtypes of PGE2 receptors are found in mammals and are designated as EP1-4. These are G-protein coupled receptors that belong to a family of seven rhodopsin-like transmembrane spanning receptors. They are structurally diffe

  Methods Results First, we compared Aβ plaque number, Aβ concentration, and neurobehavior functions between naive APP/PS1 and APP/PS1xEP1−/− mice. Significantly lower Aβ burden in APP/PS1xEP1−/− mice was evidenced by fewer plaques in the hippocampal area and a lower concentration of soluble Aβ42

  2021-08-12

  

  The EGFR belongs to the ErbB family of receptor tyrosine kinases (RTKs), comprised of four members: EGFR (ErbB1, HER1), HER2 (ErbB2), HER3 (ErbB3) and HER4 (ErbB4) [24]. HER receptors are activated by a group of epidermal growth factor (EGF) ligands and undergo homo- or hetero-dimerization during th

  In addition to grouping cases of B-ALL by cell of origin, these lymphomas can also be subcharacterized by genetic rearrangements. Fusion of the purinergic receptor P2RY8 promoter to the CRLF2 (cytokine receptor like factor 2) gene frequently occurs in B-ALL but reports of the functional consequences

  2021-08-12

  

  Elevated DPP-4 activity has been strongly associated with diabetes mellitus, IR (Röhrborn et al., 2015), metabolic syndrome (Lamers et al., 2011) and inflammation (Zhong et al., 2015). However, report has it that GC exposure increases DPP-4activity in thymocyte homogenates (Kraml et al., 2003) but t

  2021-08-12

  

  In the current study, cocaine did not significantly increase negative subjective effects and nepicastat did not increase these responses. This outcome is somewhat surprising given that the most commonly reported effect to date has been to increase the aversive properties of cocaine such as anxiety,

  2021-08-12

  

  In Arabidopsis the quartet1 (qrt1) mutant enables the same type of analysis of gametophytes (pollen) in sets of four (tetrads) derived from individual meioses 61., 62.. Pollen tetrads from one accession (Columbia-0) are used to pollinate a second polymorphic accessions (Landsberg erecta) resulting i

  2021-08-12

  

  ATP-dependent DNA ligases in vertebrates are divided in three families [7]. Family I DNA ligases are responsible for sealing the nicks during DNA replication and in long-patch base excision repair (BER). Family III DNA ligases are involved in short-patch BER. Lastly, family IV DNA ligases are involv

  2021-08-12

  

  In summary, these results are consistent with our hypothesis that chemical nitrosation of BMAA to N-BMAA results in the formation of an alkylating agent. Furthermore, we have shown that N-BMAA is more toxic than BMAA itself. Previously, methylazoxymethanol (MAM), which is also present in the cycad n

  2021-08-12

  

  It is well established that Shp-2 can function as a substrate for several RTK, such as PDGF or EGFR [23], [36]. To test whether DDR1 recognizes Shp-2 as its substrate, we overexpressed a catalytically inactive Shp-2 mutant together with DDR1b in 293 cells [31]. Immunoprecipitation of Shp-2 followed

  Gene amplification. PCR amplifications were performed using genomic DNA from the different organisms studied as template and two degenerate oligonucleotides (PP1 and PP2) as primersPP1 corresponded to the sense codons of the amino iCRT 14 motif AGGI(A/S)EM, and PP2 to the antisense sequence of the m

  2021-08-12

  

  Perturbation in the cytokine network is correlated with disruption of growth hormone and glucocorticoid (GC) homeostasis (Thissen and Verniers, 1997; Sahid El-Radhi et al., 2000; Waxman and Holloway, 2009; Zhao et al., 2014), with important physiological consequences because cytokines affect the reg

  2021-08-12

  

  Previously, to detect CDKL5 activity, we used a radioactive phosphorylation assay with amphiphysin 1 protein as a substrate [,,]. However, it is necessary to establish a safe and rapid method for analyzing CDKL5 mutant activity. Here, we report a new method for investigating autophosphorylation acti

• Application of the CPH model

  2021-08-11

  

  Application of the CPH model relies on the assumption that the hazard ratio of two observations is constant over time [2]. This enables us to infer the rate of risk of the treatment. For example, in the study of patients with pulmonary arterial hypertension (PAH) [5], the hazard ratio of a group of

  Yet, the standards fall back on the development process with justification. As shown by Littlewood and Strigini (1993), the extent to which the reliability of software (both OTS and bespoke) can be proved by testing is severely limited––not because appropriate tests cannot be devised, but because a
