Because MGO is mainly removed by the action of glyoxalase I (GLO1), the activity of this enzyme contributes to the accumulation of MGO. We recently found that quinetazone, a diuretic pharmaceutical agent, has the potential to inhibit GLO1 activity. Therefore, we explored whether diuretics that have a similar structure to quinetazone inhibit GLO1. The inhibitory characteristics of diuretics with recombinant GLO1 were spectrophotometrically determined. Cell proliferation and accumulation of MGO-derived AGEs were evaluated by MTT assay and Western blotting. Among the thiazide, thiazide-like, and loop diuretics, metolazone and azosemide were found to inhibit GLO1 activity by 97% at 100 µM. Furthermore, we examined whether the substructures of these diuretics have inhibitory activity, quinazolinone or phenyltetrazole were determined to be the minimal structures of metolazone or azosemide required for inhibition of GLO1, respectively. In proximal renal tubule-like HK-2 and vascular endothelial cell-like EA.hy926 cells, these diuretics were shown to inhibit cell proliferation and induce accumulation of MGO-derived AGEs. In contrast, the substructures of these diuretics that did not affect GLO1 activity did not cause these changes. Metolazone and azosemide have inhibitory effects against GLO1. Considering that these diuretics are clinically employed as pharmaceutical agents, high or prolonged dosages may contribute to pathogenesis through GLO1 inhibition, followed by MGO and/or AGE accumulation.</p>","PeriodicalId":9274,"journal":{"name":"Biotechnology and applied biochemistry","volume":" ","pages":"e2760"},"PeriodicalIF":3.2,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810488","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}

Despite its potential significance, the role of RYR2 in LUAD remains poorly understood. In this study, we obtained transcriptomic data (normal n = 59, tumor n = 541) from TCGA portal and RYR2 protein abundance data from cProSite, which includes 86 normal and 91 tumor samples. Additionally, we assembled a cohort of 38 patients with LUAD and collected paired tumor and adjacent non-tumor control samples. To investigate the functional impact of RYR2, we employed 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry analysis to assess cell viability and apoptosis, respectively. While mitochondria function was evaluated via measuring oxygen consumption rate. The relationship between RYR2 expression level and immune cell infiltration was analyzed by immunohistochemistry and flow cytometry analysis. Furthermore, RT-qPCR and enzyme-linked immunosorbent assay were used to quantify the expression levels of CCL14 and CXCL12. Our findings demonstrated that both the mRNA and protein levels of RYR2 were significantly downregulated in LUAD samples, and lower RYR2 levels are associated with the poor patient prognosis. Overexpression of RYR2 in A549 and H1299 cells resulted in impaired mitochondrial function, decreased cell viability, and increased apoptosis. Notably, RYR2 levels exhibited a negative correlation with tumor purity, and tumors with lower RYR2 levels showed diminished infiltration of T cells and dendritic cells. Knockdown of RYR2 in LUAD cells inhibited the production of chemokines, particularly CCL14 and CXCL12. In conclusion, our study reveals that RYR2 functions as a tumor suppressor in LUAD by inducing mitochondrial dysfunction and promoting immune cell infiltration.</p>","PeriodicalId":9274,"journal":{"name":"Biotechnology and applied biochemistry","volume":" ","pages":"e2759"},"PeriodicalIF":3.2,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810486","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}

This study has developed a codetection system based on DNA methylation markers (cytosine-phosphate-guanine [CpG]) and an STR amplification system for simultaneous personal identification and biofluid origin determination using capillary electrophoresis. This system integrates a 7-plex amplification system, comprising 5 biofluid-specific CpG markers (cg05261336 for semen, cg04011671 for peripheral blood, cg09107912 for saliva, cg15988970 for vaginal secretion, and cg18069290 for menstrual blood) and 2 control markers, with a 20-plex STR amplification system. The combined system successfully distinguished five types of body fluids from single sources (peripheral blood, semen, saliva, menstrual blood, and vaginal secretion) and generated DNA methylation profiles in mixed samples of two to four body fluids in varying proportions. The cumulative discrimination power for personal identification was calculated to be 1-3.5120 × 10^-25. Additionally, semen and vaginal secretion with 0.1 ng DNA input or kept at room temperature for 5 months could still be efficiently identified.

NPC is correlated with substantial illness and death; thus, superior treatment is desired. Rosmanol (RM) is a phenolic diterpene antioxidant extracted from the medicinal herb Rosemary (Rosmarinus officinalis). RM has been investigated for its anti-inflammatory and anti-tumor properties by numerous signaling cascades. However, the fundamental anticancer latent mechanism of RM persists as unidentified. Hence, this present research proposes to search for the anti-cancer efficacy of RM on human NPC cells CNE2 using an in vitro approach. To assess the possible molecular mechanisms of proliferation, apoptosis, cell-cycle regulatory proteins, and MAPKs/NF-κB signaling of NPC cells were administered RM (20 and 30 µM) and assayed through MTT, DCFH-DA, Rh-123 staining, AO/EB, PI, Rh-123/DAPI merge form staining, RT-PCR, and Western blot. The result was recognized that RM could reduce NPC cell viability by elevated intracellular ROS, MMP damage, and generate apoptosis. RM inhibits the Cyclin-D1, Bax, TNF-α, and NF-κB, and induces BCl-2 analyzed via RT PCR. RM attenuates the cell cycle mechanism by repressing NPC cell cycle-related proteins: CDK4/CDK6, pRB, cyclin-D1, and MAPKs/NF-κB signaling. These data established that the MAPKs/NF-κB pathway is a potential target for the remedial action of RM.

Among them, compound 4a displayed the highest ALR2 inhibitory potency (K_i: 0.211 µM) and was superior to epalrestat. In terms of α-Glu, compound 4k was shown to be more potent with a K_i of 0.049 µM, particularly versus acarbose. Compound 4d showed excellent inhibitory activity (K_i: 1.43 µM) in tyrosinase assays, much more potent than kojic acid. Molecular docking studies revealed the details of enzyme-binding interactions, which justify the respective inhibitory mechanisms observed. Structure-activity relationships reflected that compounds with strong hydrogen bonding and hydrophobic interactions led to higher potency.

Its pathogenesis includes inflammation, an excess of reactive oxygen species, and kidney damage. The present study intended to explore the nephroprotective effects of acacetin (ACN) in streptozotocin-induced diabetic animals. The following are the experimental groups: One millilitre of 0.9% saline was given to Group I (control), Streptozotocin (STZ) (diabetic animals) + 0.9% saline to Group II (DN group) (negative control), DN + ACN (15 mg/kg body weight [bw]) to Group III, and DN + Valsartan (150 mg/kg bw) to Group IV. According to the findings, ACN decreased the levels of glucose, serum creatinine (Scr), blood urea nitrogen (BUN), malondialdehyde (MDA), and proinflammatory cytokines while increasing the bw, superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) in comparison to the DN animals. The histopathological analysis revealed that the animals treated with ACN showed recovery of renal damage in the tissues caused by STZ. In the STZ-induced DN mice, ACN reduced renal damage by upregulating the proteins of 5' adenosine monophosphate-activated protein kinase (AMPK), p-AMPK, and SIRT1 and downregulating the proteins of TGF-β, COL-1, COL-IV, NF-κB, ASC, NLRP3, and GSDMD, according to western blot analysis.
