While size-exclusion chromatography (SEC) coupled with mass spectrometry (MS) is commonly used in the biopharmaceutical industry for analyzing protein therapeutics, its application to intact AAV VP components has not gained traction, presumably due to difficulties in achieving adequate resolution of VP(1−3) monomers. Herein, we describe the development of a denaturing SEC method and optimization of SEC parameters, including stationary phase pore size, column temperature, and mobile phase composition, to achieve effective chromatographic separation of VP(1−3).

Additionally, dSEC integrated with fluorescence (FLR) and ultraviolet (UV) detection can be used to semi-quantitatively identify both AAV DNA and VP components from empty and full AAV samples.

A dosage of 12.5 g crude drug/kg/d of the low-polarity fraction of Radix Bupleuri (LBR) demonstrated effectiveness in treating depression in our previous study. However, the mechanism through which BR ameliorates depression remains unclear. This study aimed to explore the polar fractions of BR and their mechanisms of action in the treatment of depression. Chronic unpredictable mild stress (CUMS) rats were continuously administered BR by oral gavage for 4 weeks. Behavioral and biochemical indicators were evaluated to assess the antidepressant effects of LBR, and transcriptomics was used to explore the relevant pathways. In addition, pseudo-targeted bile acid (BA) metabonomics was used to quantify the BA profiles. Molecular biology techniques have been used to investigate the underlying mechanisms. LBR serves as a more effective active fraction with antidepressant activity. Intervention with LBR, which is characterized by a clearly defined chemical composition, significantly ameliorated depression-like behavior and biochemical indicators in rats subjected to CUMS. Notably, marked improvements were observed in the levels of total bile acids (TBAs) in the blood, liver, and ileum. Mechanistically, liver transcriptome analysis suggested that bile secretion may be a crucial pathway for alleviating depression after LBR treatment. Ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS) BA metabonomics indicated that TCA, β-MCA, γ-MCA, Tβ-MCA, and UDCA in the liver, Tβ-MCA, TCA, βMCA, GHDCA, and GLCA in the ileum, and β-MCA, CA, and DCA in the hippocampus were the potential therapeutic targets. In addition, molecular biology experiments showed that LBR exerts antidepressant effects by regulating the FXR/SHP/CYP7A1 pathway in the liver, the FXR/FGF15/ASBT pathway in the ileum, and the FXR/CREB/BDNF pathway in the hippocampus. In conclusion, LBR attenuated depression by moderating BA homeostasis through FXR and related genes within the liver-gut-brain axis.</div></div>","PeriodicalId":16685,"journal":{"name":"Journal of pharmaceutical and biomedical analysis","volume":"253 ","pages":"Article 116523"},"PeriodicalIF":3.1,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142531557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, analysis of clinical samples reveals that YJTQG can reduce the inflammatory factors and alleviate the symptoms of RA patients. Quantitative proteomic analysis of serum proteomes of RA patients identifies the potential therapeutic targets of YJTQG.

Network pharmacology analysis discloses COX1/2 and NOS2 as potential targets of key compounds in YJTQG and protein-protein interaction network analysis reveals TNFα, IL-6, and STAT3 as possible core targets of YJTQG. Bioinformatic and patient sample analyses indicate that YJTQG may reduce S100A8 expression by suppressing its transcription.

Recently, we developed a novel nano liquid chromatography coupled to high resolution mass spectrometry (nanoLC-HRMS) method for the analysis and thus the detection of the intact glycoforms of hCG. Here, a sorbent functionalized with the Jacalin lectin was evaluated in solid-phase extraction (SPE) for its potential to fractionate the hCG glycoforms prior to their nanoLC-HRMS analysis at the intact level, which may facilitate the detection of low-abundance glycoforms and may lead to a more detailed characterization of the hormone glycosylation. A commercial sorbent based on Jacalin immobilized on Sepharose and having a lectin density of 4.5 mg per ml of gel was selected to carry out SPE and its capacity was estimated to be of some tens of μg of hCG per ml of lectin sorbent. Next, the SPE protocol was modified to improve the extraction recoveries. Especially, it was noticed that an extensive pre-conditioning procedure prior to the first use of a cartridge was necessary to remove the residual non-grafted lectins. Indeed, if non-grafted lectins are not eliminated, they may bind a part of hCG glycoforms preventing their retention by the sorbent, leading to low extraction recoveries (around 10 %). With the extensive pre-conditioning procedure, the average extraction recoveries for both hCGα and hCGβ glycoforms were about 50 %, with either recombinant or urinary hCG. Qualitatively, the fractionation of hCG glycoforms between the washing and elution fractions was achieved with the urinary hCG sample by determining the number of glycoforms detected in each fraction. It appears that 12 hCGα glycoforms have a low affinity (detected only in the washing fraction), 1 a low-medium affinity (detected in washing and elution 1 fractions), 16 a medium affinity (detected in washing, elution 1 and 2 fractions), and 12 a high affinity (detected only in elution 1 and 2 fractions). For the hCGβ glycoforms, similarly, 3 have a low affinity and 12 a low-medium affinity. Additionally, the 3 hCGβ glycoforms were detected better. A different behavior was observed with the recombinant hCG sample, which indicates glycosylation differences between the two hCG samples. This shows the potential of lectin-based affinity fractionation before nanoLC-HRMS analysis to better characterize the glycosylation state of hCG at the intact level.</div></div>","PeriodicalId":16685,"journal":{"name":"Journal of pharmaceutical and biomedical analysis","volume":"252 ","pages":"Article 116525"},"PeriodicalIF":3.1,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142502441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An alcoholic liver disease (ALD) model in male rats was established, and the rats were treated with PTH given at a prescribed dosage. The hepatoprotective components of PTH and their exposure in the serum of PTH-treated rats were systematically identified. Quantitative proteomics was employed to find differentially expressed proteins. The key targets were screened by bioinformatic analysis and further validated by Western blotting (WB) and molecular docking.

A total of 53 differentially expressed proteins that were reversed by PTH were successfully identified in rat liver tissues. Retinol metabolism and the PPAR signaling pathway may play a key role in ameliorating alcohol-induced liver injury after PTH intervention. In particular, protein CYP2, FATCD36, FATP, ACS, and CPT-2 in these two pathways may be key targets for the therapeutic effects of PTH, with the same reversal observed by WB. Molecular docking analysis further revealed that these five proteins exhibited generally stable binding with the five main components of PTH. The hepatoprotective effects of PTH may be exerted through the modulation of key targets within pivotal pathways.
