Thymus transplantation regulates blood pressure and alleviates hypertension-associated heart and kidney damage via transcription factors FoxN1 pathway
2023, International ImmunopharmacologyAn analytical quality by design approach towards a simple and novel HPLC-UV method for quantification of the antifibrotic peptide N-acetyl-seryl-aspartyl-lysyl-proline
2022, Analytical BiochemistryCitation Excerpt :Pradelles et al. first described an EIA for Ac-SDKP in 1990, using acetylcholinesterase-Ac-SDKP conjugate as the tracer, rabbit antiserum, and mouse anti-rabbit IgG antibody-coated 96-well plate. However, a limitation of this method was the lack of specificity, resulting in cross-reactivity with Ac-SDKP-like materials [12]. Junot et al. reported an improved EIA assay for the amidated analogue of the peptide, with successful quantification of the peptide analogue in the mouse plasma samples without interference from the endogenous Ac-SDKP.
Ac-SDKP ameliorates the progression of lupus nephritis in MRL/lpr mice
2012, International ImmunopharmacologyCitation Excerpt :In human active LN, the expression of TGF-β1 and MCP-1 mRNA in the urinary sediment was significantly elevated and correlated with SLEDAI score and histologic activity index, suggesting the importance of inflammatory infiltration and TGF-β1 expression in the progression of LN [7]. N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) is an endogenous tetrapeptide present in plasma and mononuclear cells [8]. Ac-SDKP is produced by cleavage of its precursor thymosin-β4 under catalyzation of prolyl oligopeptidase [9].
Quantification of N-acetyl-seryl-aspartyl-lysyl-proline in hemodialysis patients administered angiotensin-converting enzyme inhibitors by stable isotope dilution liquid chromatography-tandem mass spectrometry
2011, Journal of Pharmaceutical and Biomedical AnalysisCitation Excerpt :However, the few useful and reliable assays to screen endogenous Ac-SDKP in human plasma such as hemodialysis whom was administered ACE inhibitors have been reported. The old papers described that the enzyme immunoassay (EIA) was developed for the investigation of distribution of N-terminal thymosin β tetrapeptides [11,12]. Junot et al. reported that specific EIA was developed for sensitive and selective monitoring Ac-SDKP in mouse plasma and tissues [13].
