To study the effect of Baidu Powder on protecting ARDS mice model and its underlying active ingredients and targets intervening in COVID-19. The optimal LPS concentration was selected for the induction of mouse ARDS model, and the protective effect of Baidu Powder prophylactic administration on LPS-induced ARDS mouse models was explored by mouse survival time analysis, lung wet/dry weight (W/D) ratio, pathological staining, and inflammatory factor detection. On the basis of pharmacodynamics, the network pharmacological analysis was used for target prediction for future mechanism study. 5 mg/kg LPS was selected for the construction of a mouse ARDS model, based on a mortality rate of 87% and the lung W/D ratio of 5.29 ± 0.23. Prophylactic administration of Baidu Powder at 125 g/L significantly reduced death, lung damage, inflammatory cell infiltration, and cytokine production (TNF-α, IL-6, and IL-10) caused by LPS-induced ARDS. The results of network pharmacological analysis showed that 42 target genes of Baidu Powder intervening in COVID-19 were involved in 30 biological processes related to COVID-19 and inflammation, and 11 signaling pathways related to lung diseases or inflammation. 5 mg/kg LPS can successfully establish a mice ARDS disease model; 125 g/L Baidu Powder prophylactic administration does not have toxicity and has a certain effect on protecting ARDS mouse models induced by LPS.

This study aimed to identify the key target genes for IH treatment and explore their possible roles in the IH pathophysiology. Gene records were acquired from the Gene Expression Omnibus database. Utilizing integrated weighted gene co-expression network examination, gene clusters were determined. Single-sample gene set enrichment analysis was performed to gauge immune infiltration.

Ultimately, a set of five pivotal genes associated with the ailment was identified (<i>NETO2</i>, <i>IDO1</i>, <i>KDR</i>, <i>MEG3</i>, and <i>TMSB15A</i>). A nomogram for predicting IH diagnosis was constructed based on hub genes. The calibration curve showed valid agreement between the prediction and conclusion that the key genes in the model were clinically significant.

Protein levels of apoptosis-related proteins (Bax and Bcl-2) and ZG16 were quantified by western blotting. In vitro function analysis referred to western blotting, wound healing assay and CCK-8.

The functional role of HAND2-AS1 was analyzed using xenograft tumor models in vivo<i>.</i> In tissues and cells of CC, HAND2-AS1 was downregulated. We observed that HAND2-AS1 overexpression declined CC cell proliferation and migration while facilitating apoptosis. We further verified that when HAND2-AS1 is overexpressed it reduced CC tumor development in vivo. In CC cells and tissues, miR-3118 competed with HAND2-AS1 and was elevated. Further it was noted that the HAND2-AS1 when overexpressed, lessened the survival of CC cells, however overexpression of miR-3118 restored these changes. ZG16 was shown to be a target of miR-3118, it was found that ZG16 was downregulated in CC tissue and cells. We observed, high expression of ZG16 partially restored the enhanced malignant phenotype caused by miR-3118 overexpression.

Studies have demonstrated that antioxidants (MnSOD, CAT, and GPx1) may reduce the complications associated with T2DM. The purpose of the study is to correlate the role of antioxidant gene polymorphisms in the pathogenesis of DN among T2DM individuals in the South Indian population. It clarifies the importance of early manifestation and reliable genetic indicators modulating the oxidative stress mechanism in DN. The study participants were divided and grouped as Group 1: Control, Group 2: T2DM without DN, and Group 3: T2DM with DN (n = 100 in each group). The levels of plasma glucose, HbA1c, renal profile, SOD, CAT, GPx1, MDA, and TAS were assessed. MnSOD (rs4880), CAT (rs1049982), and GPx1 (rs1050450) polymorphisms were genotyped via Tetra-arms PCR. The genotypes of GPx1 depict a significant role in the progression of DN in T2DM patients (co-dominant [OR: 2.134; 95% CI (1.202–3.788), <i>p</i> &lt; 0.01], dominant [OR: 2.015; 95% CI (1.117–3.634), <i>p</i> = 0.02], and recessive model [OR: 2.215; 95% CI (1.235–3.972), <i>p</i> = 0.008]); whereas rs4880 and rs1049982 polymorphisms are not associated with DN progression. As a result, GPx1 (rs1050450) polymorphism could be a diagnostic risk factor for developing DN in T2DM patients. Moreover, the genotypes of rs4880 and rs1049982 polymorphism show significant difference in the antioxidant parameters compared to the genotypes of rs1050450. In contradiction to earlier studies, the current study demonstrates that the genotypes of rs1050450 (GPx1) can be considered as an influential component for higher susceptibility and risk of developing DN in T2DM patients among the South Indian population.</p>","PeriodicalId":482,"journal":{"name":"Biochemical Genetics","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142219730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
