The Indian macrofungal flora consists of a diverse range of distinct species that have long been valued by various tribal groups for their medicinal and culinary qualities. During the process of documenting indigenous mushroom species, one unique edible Russula sp. was collected from the Pinus-dominated forest of the East Khasi Hills district of Meghalaya. Following a thorough assessment of the morphological traits and molecular phylogenetic analysis, this distinct species has been identified as Russula pseudojaponica, a new record from India. In order to investigate its therapeutic potential, a methanolic fraction was prepared and characterized for myco-chemicals. A substantial quantity of different secondary metabolites like carotenoids, ascorbic acid, and phenolics has been detected. The methanolic fraction also had notable antioxidant activity, displaying strong capabilities in scavenging DPPH and ABTS radicals, possessing high reducing power, and chelating capacity. In addition, the extract demonstrated the capacity to hinder the growth of Listeria monocytogenes, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, Salmonella typhi, and Staphylococcus aureus, as seen in the broth microdilution experiment. Furthermore, it induced morphological changes in bacterial cells, which were seen by scanning electron microscopy. Moreover, the extract demonstrated the ability to inhibit the proliferation, clonogenicity, and migratory potential of lung carcinoma cells, suggesting its potential as an anticancer agent. The extract successfully arrested the cell cycle progression in the S phase of cell division. Involvement of the intrinsic mitochondrial pathway of apoptosis was also observed after extract treatment. Hence, based on the findings of this study, this exceptional fungus has the capacity to function as an organic reservoir for the creation of novel medications to counteract illnesses associated with oxidative stress, bacterial ailments, and cancer.</p>","PeriodicalId":9274,"journal":{"name":"Biotechnology and applied biochemistry","volume":" ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143954760","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}

The liver plays a vital role in metabolism; however, hyperglycemia can induce liver damage and disrupt its normal functions. Wharton's jelly mesenchymal stem cells (WJMSCs) engineered to express the carboxyl terminus of HSP70-interacting protein (CHIP) have demonstrated protective effects against hyperglycemia-induced damage in various organs. Nonetheless, the potential hepatoprotective effects and underlying mechanisms of these modified stem cells in diabetic livers remain unclear. Therefore, this study aimed to evaluate the efficacy of CHIP-transfected WJMSCs in mitigating hyperglycemia-induced hepatic injury in diabetic rats and to elucidate the associated protective mechanisms. Diabetic rats received tail vein injections of WJMSCs either overexpressing or silenced for CHIP. Seven weeks post-transplantation, all rats were sacrificed, and liver tissues were harvested for histological staining and Western blot analysis. The findings indicated that CHIP-overexpressing WJMSCs significantly reversed hyperglycemia-induced liver damage, reducing tissue injury, fibrosis, and glycogen deposition. These cells also alleviated hepatic inflammation and apoptosis. Moreover, they regulated oxidative stress pathways by lowering gp91-phox, Rac1, and phosphorylated PKCζ levels, while enhancing phosphorylated Nrf2 and SOD-2 expression. Additionally, the modified WJMSCs suppressed STAT3 activation and downregulated FOXO3a, suggesting a role in attenuating fibrosis and triglyceride accumulation in diabetic livers. Overall, CHIP-overexpressing WJMSCs reversed hyperglycemia-induced hepatic alterations by mitigating inflammation and oxidative stress while also modulating pathways related to fibrosis and lipid metabolism. These results highlight the therapeutic potential of CHIP-modified WJMSCs in managing diabetic liver complications and offer promising avenues for future treatment strategies.</p>","PeriodicalId":9274,"journal":{"name":"Biotechnology and applied biochemistry","volume":" ","pages":"e2771"},"PeriodicalIF":3.2,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143966239","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}

Treatment strategies for AD vary depending on cognitive and behavioral symptoms, with cholinergic replacement therapy using acetylcholinesterase (AChE) inhibitors being one of the primary approaches. Recent studies have also identified human carbonic anhydrases (hCAs) as significant therapeutic targets for AD, offering new opportunities for the development of innovative treatments. Carbonic anhydrase inhibitors have been shown to prevent early mitochondrial damage and inhibit H₂O₂ production, thereby reducing amyloid plaque formation. Building on the promising potential of hydrazones particularly sulfonyl hydrazones as anticholinesterase agents, we synthesized 12 novel chlorine-substituted sulfonyl hydrazone compounds containing aryl sulfonate ester groups.

The long noncoding RNA plasmacytoma variant translocation 1 (PVT1) and its targets, microRNA-146a and sirtuin 1 (SIRT1), affect BC development; however, their predictive abilities in early detection of BC and its metastatic potential are largely unknown. This study investigated serum PVT1, miR-146a, and SIRT1 as potential diagnostic and predictive biomarkers for BC and its metastasis. 120 BC patients, 40 breast fibroadenoma (BFA) patients, and 80 healthy volunteers were enrolled. An upregulation of serum PVT1 expression and SIRT1 protein levels was observed in BC patients compared to controls and BFA patients. miR-146a was downregulated in BC and BFA patients compared to controls, with lower levels in BFA compared to BC. Metastatic BC patients showcased higher PVT1 and SIRT1 and lower miR-146a levels than the nonmetastatic group. PVT1 and miR-146a were associated with the risk of developing BC among healthy controls. Combining PVT1 and miR-146a in a predictive panel showed substantial diagnostic accuracy for BC (area under the curve [AUC] = 0.91, 95% CI = 0.87-0.95). Only PVT1 was a predictor of the risk of developing BC among BFA cases and the risk of metastasis among BC patients. In BC, PVT1 was negatively correlated with miR-146a and positively correlated with SIRT1 and invasive lobular tumor type. Conclusively, our results highlight the PVT1/miR-146a/SIRT1 trajectory as a potential biomarker for early diagnosis and prognosis of BC.

The yeast surface display (YSD) technology is a powerful tool for the expression of recombinant laccases that can be used to design robust oxidative biocatalysts and combine stability and flexibility in a whole-cell system. In order to gain insights on improving the laccase performance, we investigated the release, from the yeast's surface, of a recombinant laccase (OB1) from Saccharomyces cerevisiae EBY100's cell surface. The laccase, or derivatives thereof, was released as a fusion protein connected, by a flexible peptide linker, to a carrier protein (Aga2 adhesin). The optimum conditions for the release of the fused protein were determined by applying a 2² factorial experimental design, exploring biomass and dithiothreitol concentration as the variables. The released Aga2-3x(G4S)-OB1 derivatives were biochemically characterized and compared to the whole-cell system. Laccase variant TX13A-OB1 was the best-performing fusion protein out of six variants, with a K_m value of 0.0137 ± 0.0032 mM and V_max 0.0075 ± 0.0001 (µmol min^-1) for ABTS. All variants showed thermostability at 60°C and retained over 50% relative activity within a pH range of 3-5, compared to the parental protein. No significant differences in oxidation performance were determined with respect to the oxidation profile of gallic acid, vanillic acid, and catechol. On the other hand, there was an improvement in ferulic acid. Additionally, laccase relative activity remained above 60% in the presence of 10%-20 % ethanol for all variants.
