(Indian Sandalwood), a valued tree species known for its fragrant heartwood and essential oil is facing increasing threat due to severe anthropogenic pressures compounded by climate change which has resulted in depletion of its adaptive gene pool. The present study investigates the transcriptome-level responses of nine sandalwood genotypes sourced from diverse climatic zones to identify adaptive genes in the species. Comparative transcriptomics predicted 727, 1141 and 479 differentially expressed transcripts (DETs) across wet vs. dry; monsoon vs. dry and wet vs. monsoon conditions, respectively, and majority of DETs were up-regulated in samples sourced from high rainfall areas. Transcripts including heat shock proteins, Zinc finger binding protein, ribosomal proteins, transcription factors and protein kinase were identified as probable regulators of climate adaptation in <i>S. album.</i> The expression changes of eight selected transcripts were further validated by real-time quantitative PCR. Protein-protein interaction analysis revealed key hub transcripts involved in climate response, while alternative splicing events in transcripts such as SURP and G-patch domain-containing protein 1-like protein, G-type lectin S-receptor-like serine/threonine protein kinase B120, Tetraspanin-3 and ARM repeat superfamily protein indicated the probable role of alternate splicing in increasing the transcript diversity during adaptation. This study presents the first insight into the molecular mechanisms of climate adaptation in the species and can form the basis for specific interventions such as selective breeding, genetic manipulation, and habitat management for conservation and long-term survival of sandalwood.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s13205-025-04218-4.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":"15 3","pages":"64"},"PeriodicalIF":2.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11829887/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439371","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}

Here in this research, we studied the effects of <i>E. mollis</i> (<b>EM</b>) petroleum ether extract (EM-PE) on the highly aggressive breast cancer cell line MDA-MB-231. The result from phytochemical analysis demonstrated the presence of tannins and saponins in EM-PE, of which, saponins made up more than 50% of the extract's mass. Cytotoxicity results, which were obtained from MTT assay and microscopic observation, suggested the potential of EM-PE to inhibit the growth of MDA-MB-231 cells with low IC₅₀ value (approximately 30 μg/mL) and remarkably high selectivity index (> 4.78). Further evaluation indicated that EM-PE inhibited MDA-MB-231 cells growth in a dose-dependent manner. Interestingly, we found that EM-PE induced senescence in MDA-MB-231 cells via the activation of senescence-associated β-galactosidase and the transcriptional upregulation of p21 (3.7 times) and p27 (1.4 times). In consistent with this effect, pre-treated cancer cells showed no proliferative recovery after EM-PE removal. In addition, EM-PE could dramatically hinder breast cancer cells invasion (as much as 15.07-fold), which was shown in Transwell invasion assay, together with the decreased transcription of the important metastatic-involved <i>SNAIL1</i> gene. Overall, our study, for the first time, exhibits the anti-proliferation and anti-invasion effects of EM extract on highly metastasis breast cancer cell line MDA-MB-231.

Irrespective of tremendous advancements in early detection and treatment, this disease still has high mortality rates. This is due to the development of antibiotic resistance, which significantly reduced the efficacy of antibiotics, rendering them useless against this bacterial infection. This, in turn, causes immune system evasion, antibiotic treatment failures, and recurrence of disease in patients. Regarding this, photodynamic inactivation (PDI) may serve as a useful substitute for antibiotic therapy against drug-resistant <i>mycobacteria</i>. This century-old therapy is already being used in cancer treatment, dentistry, and skeletal and cardiovascular diseases, but it is not yet used in tuberculosis treatment. Researchers have previously used PDI to eradicate other members of the genus <i>Mycobacteria</i> in both in vitro and in vivo settings. This suggests PDI can be explored against <i>M. tuberculosis</i> too. The one limitation associated with PDI is the use of chemical photosensitizers, which are fatal to normal tissues and induce side effects. Recent studies suggest herbal photosensitizers are equally potent as chemically synthesized ones. Therefore, herbal photosensitizers could be used to solve the problem because of their less toxicity to healthy tissues and decreased frequency of side effects. This review emphasizes the importance of herbal photosensitizers and their role as anti-tuberculosis drugs in PDI therapy and also presents five potential herbal photosensitizers-curcumin, quercetin, resveratrol, aloe emodin, and phloretin that could be utilized in the clinical development of PDT-mediated tuberculosis therapies.</p>","PeriodicalId":7067,"journal":{"name":"3 Biotech","volume":"15 2","pages":"48"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11747057/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143021420","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}

AMPs, derived from natural sources, exhibit promising antiviral properties by disrupting viral membranes, inhibiting viral entry, and modulating host immune responses. Preclinical studies demonstrate that peptides such as defensins, cathelicidins, and lactoferrin can effectively reduce SARS-CoV-2 replication and inhibit viral spread. In addition, AMPs have shown potential in enhancing the host's antiviral immunity. Despite these promising outcomes, several challenges require assessments before transforming into clinical translation. Several issues related to peptide stability, cytotoxicity, and efficient delivery systems pose significant limitations to their therapeutic application. Recent advancements in peptide engineering, nanotechnology-based delivery systems, and peptide conjugation strategies have improved AMPs stability and bioavailability; however, further optimization is essential. Moreover, whilst AMPs are safe, their effects on host cells and tissues need a thorough investigation to minimise potential adverse reactions. This review concludes that whilst AMPs present a promising route for antiviral therapies, particularly in targeting SARS-CoV-2, extensive clinical trials and additional studies are required to overcome current limitations.

Additionally, network pharmacology analyses were conducted to identify potential molecular targets of I3C in GCI. Bilateral common carotid artery occlusion (BCCAO) surgery was performed to induce GCI. I3C was administered orally for 14 days, and cognitive and memory functions were assessed using the Y-maze and Morris water maze paradigms. Biomarkers of oxidative stress (MDA, Nrf2, SOD, and CAT), inflammatory markers (NF-κB, TNF-α, and IL-10), and AChE enzyme activity were evaluated. The results demonstrated that I3C treatment significantly inhibited AChE activity, improved spontaneous alternation (%) in the Y-maze test, increased the number of entries and time spent in the platform zone, and reduced escape latency in the Morris water maze test, indicating enhanced cognitive and memory functions. I3C treatment also increased brain levels of Nrf2, SOD, and CAT while reducing MDA levels. Furthermore, it decreased pro-inflammatory markers such as NF-κB and TNF-α and elevated the anti-inflammatory marker IL-10, suggesting neuroprotection through the mitigation of oxidative stress and inflammation.
