Candidate gene analysis revealed strong associations with key regulators of hormonal and metabolic pathways. Notably, ethylene biosynthesis and signalling genes-OsACO (LOC_Os09g39720, LOC_Os06g37590), CTR1 (LOC_Os09g39320), and ERS1 (LOC_Os03g49500) were linked to enhanced coleoptile elongation under hypoxia.

However, there is limited knowledge about the potential use of zeolite and nano-zeolite in alleviating Cd-induced stress in plants, particularly in <i>Datura stramonium</i> L. This study aimed to investigate how the application of zeolite and nano-zeolite affects various traits of Jimsonweed under Cd toxicity stress. Key aspects examined included plant growth, Cd absorption, relative water content of leaves (RWC), photosynthetic pigments, malondialdehyde (MDA) content, hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) levels, proline, nitrogen content, and the activity of the enzyme glutathione-S-transferase (GST). The Jimsonweed plants successfully grew from the onset of cultivation, even in soil contaminated with Cd. They were subjected to various levels of zeolite and nano-zeolite during their growth. Exposure to Cd resulted in decreased root and shoot dry weight, lower nitrogen content in leaves, reduced levels of photosynthetic pigments and RWC, and increased Cd accumulation in the roots, particularly within the shoots. Higher Cd transfer to the shoots was accompanied by elevated levels of H<sub>2</sub>O<sub>2</sub>, MDA, proline, and enhanced GST enzyme activity. In contrast, the use of zeolite and nano-zeolite had a significant positive impact on several aspects of the plants. It significantly (<i>p</i> < 0.05) increased root and shoot dry weight, leaf nitrogen content, levels of photosynthetic pigments, proline, GST activity, and RWC. Moreover, it effectively reduced damage caused by lipid peroxidation and H<sub>2</sub>O<sub>2</sub>. Furthermore, the application of zeolite resulted in decreased concentrations of Cd in plant tissues and inhibited the transfer and accumulation of Cd in the shoots. The findings indicated that Jimsonweed can accumulate Cd. Additionally, using zeolite, especially nano-zeolite, can effectively limit Cd absorption. Both zeolite and nano-zeolite treatments led to higher accumulations of hyoscyamine and scopolamine, with increases of 67% and 71% over the control, respectively, when exposed to 200 mg/kg of Cd. In conclusion, Jimsonweed has the potential to be used in remediating Cd-contaminated soils. The application of zeolite and nano-zeolite not only helps purify Cd-contaminated soil and reduces the accumulation and transfer of Cd but also enhances the activity of alkaloids and antioxidants, thereby protecting against the damaging effects of Cd-induced stress.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13205-025-04442-y.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":"15 8","pages":"266"},"PeriodicalIF":2.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12290145/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726436","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}

At farrowing, lambs were identified as having low birth weights (LBWs, < 4.0 ± 0.35 kg) or normal birth weights (NBWs, > 5.50 ± 0.50 kg). NBW lambs were selected for further experiments. On day 60, lambs were weaned onto a common diet. A total of 120 NBW Tibetan male lambs (18.39 ± 1.25 kg) were randomly assigned to four groups. The control group (PKM control, PC) was fed a basal diet, while the three experimental groups were fed diets supplemented with 15% (low-PKM, LP), 18% (moderate-PKM, MP), and 21% (high-PKM, HP) PKM for 120 d, respectively. On days 1 and 120, body weight was recorded per pen to calculate average daily gain (ADG). At the end of the experiment, twenty Tibetan sheep (<i>n</i> = 5 per treatment) were selected randomly for slaughter at a commercial slaughterhouse. The rumen fluid was collected for fermentation parameter and microbiome analysis. The results indicated that both the final weight and ADG of the lambs were significantly lower in the HP group than in the PC, LP, and MP groups (<i>P</i> < 0.05). Furthermore, the NH<sub>3</sub>-N content and pH of the rumen fluid samples were significantly lower in the HP group than in relative to the PC group (<i>P</i> < 0.05). In addition, the relative abundances of Actinobacteria and Patescibacteria were greater in the MP group than in the PC group (<i>P</i> < 0.05). The abundances of <i>F082_unclassified</i>, <i>Succiniclasticum</i>, and <i>Prevotella_1</i> (<i>P</i> < 0.05) were greatest in the PC group, whereas the abundances of <i>Ruminococcaceae_NK4A214_group</i> and <i>Christensenellaceae_R-7_grou</i>p were significantly lower (<i>P</i> < 0.05). In summary, the dietary 18% PKM never negatively affected growth, rumen pH and NH<sub>3</sub>-N content of the rumen in Tibetan sheep, potentially related to alterations in the ruminal fibrinolysis-associated microbiota. Our findings provide practical evidence for the supplementation of PKM in Tibetan sheep feeds.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":"15 8","pages":"268"},"PeriodicalIF":2.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12290156/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726433","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}

Tau is phosphorylated by Ser/Thr kinases such as GSK3β, CDK5, MAPK14, and MARK2, as well as Tyr kinases like Fyn. Given the large crosstalk among these kinases, targeting one of these kinases is ineffective in treating tauopathies such as AD, highlighting the need for a multi-targeted approach. In this study, we targeted key kinases involved in Tau hyperphosphorylation using compounds derived from the medicinal plant <i>Berberis lycium (B.ly.)</i>, which is reported to have anti-inflammatory, autophagy, and antioxidant properties. We employed virtual screening, ADMET evaluation, PASS analysis, DFT, molecular dynamics (MD) simulation, and MM/PBSA studies to assess the interaction of <i>B.ly.</i> compounds with CDK5, Fyn, GSK3β, MARK2, and MAPK14. Apigenin-7-O-glucoside (A7OG) was selected for its strong binding affinity within the ATP-binding pockets of these kinases. MD simulations demonstrated that A7OG exhibited promising inhibitory effects on CDK5, Fyn, MARK2, and MAPK14, with minimal fluctuation in its interaction with GSK3<sub>β</sub>. MM/PBSA analyses indicated stable binding energies for all the kinase-A7OG complexes. Our multitargeted investigations revealed that A7OG could be a promising molecule implicated in modulating tau hyperphosphorylating kinases that could lead to the development of therapeutic interventions in AD treatment.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13205-025-04413-3.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":"15 8","pages":"252"},"PeriodicalIF":2.6,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12254455/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625256","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}
