Addressing this challenge, we devised an innovative biocatalytic strategy and biological solution for large-scale SI production. Endo 15, an endophyte from <i>Siraitia grosvenorii</i>, exhibited excellent proficiency in SI synthesis, achieving a remarkable 50.65% SI abundance. By harnessing the extracellular protein of Endo 15 (EP), we further escalated SI abundance to 83.59 ± 2.5%, accompanied by full substrate conversion. Delving into the underlying mechanisms, we identified Exo15, a distinct functional protein derived from EP, displaying merely 48.88% amino acid similarity to the yeast exo-1,3-beta glucanase (Exg1). Successfully overexpressing Exo15 in <i>E. coli</i>, we confirmed its functionality in line with EP. Exo15 exhibited exceptional catalytic prowess, efficiently hydrolyzing mogroside V into the high-potency sweetener SI, with unparalleled activity and specificity. Our groundbreaking approach yielded an impressive SI titer of 54 g/L, coupled with an average conversion rate of 2.5 g/L per hour. These outstanding outcomes underscore the immense potential of Exo15 in cost-effective industrial production of the premium natural sweetener, siamenoside I, paving the way for its widespread adoption.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13205-025-04260-2.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":"15 4","pages":"94"},"PeriodicalIF":2.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11926301/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This comprehensive review explores the potential of bacterial biofilms in bioremediation, focusing on their ability to degrade and transform a wide array of pollutants, including heavy metals, persistent organic pollutants (POPs), oil spills, pesticides, and emerging contaminants, such as pharmaceuticals and microplastics. The unique structural and functional characteristics of biofilms, including their extracellular polymeric substance (EPS) matrix, enhanced genetic exchange, and metabolic cooperation, contribute to their superior pollutant degradation capabilities compared to planktonic bacteria. Recent advancements in biofilm-mediated bioremediation include the application of genetically engineered microorganisms, nanoparticle-biofilm interactions, and innovative biofilm reactor designs. The CRISPR-Cas9 system has shown promise in enhancing the degradative capabilities of biofilm-forming bacteria while integrating nanoparticles with bacterial biofilms demonstrates significant improvements in pollutant degradation efficiency. As global pollution rises, biofilm-based bioremediation emerges as a cost-effective and environmentally friendly approach to address diverse contaminants.

The complex interaction between antioxidants and acetylation is an important factor that contributes to the slow progression of treatment. This study highlights the development of GC resistance in COPD through 4-hydroxynonenal (4-HNE), multidrug resistance-associated protein 1 (MRP1), histone deacetylase 2 (HDAC2), and nuclear related factor 2 (Nrf2), using enzyme-linked immunosorbent assays, western blotting, and siRNA silencing. Our results suggest that long-term exposure to cigarette smoke can increase 4-HNE toxicity via reactive oxygen species (ROS)-induced lipid peroxidation and decrease the expression of MRP1, histone HDAC2, and Nrf2. Together, these molecules form and enhance the cyclic resistance pathway in COPD, including MRP1 reducing 4-HNE efflux, 4-HNE down-regulating HDAC2 expression by oxidation, HDAC2 reducing Nrf2 transcription by deacetylation, and Nrf2 reducing MRP1 expression through acetylation. The HuaTanJiangQi Capsule (HTJQ) reduces GC resistance via a triple regulatory pathway by enhancing the activity of HDAC2, promoting the transcription of Nrf2, up-regulating the expression of MRP1, and reducing lipid peroxidation induced by ROS.

That autism-associated protein POGZ has recently been involved in tumorigenesis intrigues us exploring its relevant molecular regulatory network in THCA. Clinical characteristics and intermolecular relationships were dissected by bioinformatics. Interaction between POGZ and MAD2L2 was examined by Co-IP assay. Targeting relationships between miR-27b-3p and POGZ/LINC01355 was verified by sequence prediction and dual-luciferase reporter detection. Cellular effects of genes were assessed by CCK-8 assay, clone formation assay, and Transwell assay, and further confirmed by a tumor-bearing nude mice model. Our results demonstrated a decrease in POGZ expression in THCA tissues and cell lines, and an interaction between POGZ and MAD2L2 protein. POGZ inhibited both the proliferation and motility of THCA cells, with these effects being reversed upon MAD2L2 silencing. LINC01355 exhibited low expression level and a positive correlation with POGZ in THCA. Both miR-27b-3p and LINC01355 were identified as regulators of POGZ through targeting. Elevated miR-27b-3p suppressed POGZ expression. LINC01355 promoted POGZ and counteracted the inhibitory effects of miR-27b-3p. Furthermore, miR-27b-3p increased the proliferation and motility of THCA cells, an effect that was blocked by LINC01355. At the animal level, POGZ, LINC01355, and MAD2L2 all attenuated tumor growth in THCA. Collectively, POGZ restrains THCA growth by interacting with MAD2L2 protein, and POGZ modulation involves a complex interplay orchestrated by LINC01355-targeted miR-27b-3p.
