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}

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. Histopathological analysis revealed improved integrity of CA1 neurons in BCCAO rats treated with I3C. Network pharmacology studies identified TP53, AKT1, TNF, STAT3, BCL2, SRC, ESR1, CCND1, CASP8, and CASP3 as the top ten molecular targets for I3C in the context of GCI. Our in vivo data, supported by network pharmacology studies, suggest that I3C's neuroprotective and cognitive-enhancing effects are driven by its ability to alleviate oxidative stress, inflammation, and apoptosis.

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.

Comprehensive bioinformatics analyses were conducted using data from The Cancer Genome Atlas (TCGA) and various advanced database, including cBioPortal, UALCAN, TIMER, Prognoscan, TISIDB, KM Plotter, and The Human Protein Atlas, to provide a detailed evaluation of MRPL55's role in cancer. The findings were further validated through experimental studies. Pan-cancer analysis of TCGA/ICGC data revealed significant amplification of MRPL24 across multiple cancer types, with the highest amplification rate of 60% observed in metastatic breast cancer. MRPL24 was found to be overexpressed in primary breast tumors, metastatic, and various molecular subtypes of breast cancer. High MRPL24 expression was associated with poor prognosis and lower survival rates in breast cancer patients. RT-PCR and western blot confirmed MRPL24 depletion in breast cancer cells. Knockdown of MRPL24 was shown to suppress proliferation, and clonogenic potential in breast cancer cells and inhibit cell migration. Additionally, MRPL24 depletion sensitized breast cancer cells to PD0325901 and 5-FU treatment. Mechanistic studies revealed that MRPL24 knock-down downregulates mRNA levels of oncogenic genes, including c-MYC, BRD4, WNT3, and STAT3. Positive correlations were observed between MRPL24 and key genes involved in ferroptosis regulation, such as ERBB2, ERBB3, GRB2, PIK3CA, AKT1, MAPK3, and MAPK1. Finally, through virtual screening and molecular dynamics simulations, we have identified three FDA-approved drugs with strong binding affinities and interactions with MRPL24.

We extracted 430 genes from literature associated with both insulin resistance and inflammation. The highly significant pathways were Toll-like receptor signaling, PI3K-Akt signaling, cytokine-cytokine receptor interaction, pathways in cancer, TNF signaling, and NF-kappa B signaling. Among the 297 common genes in all datasets of various T2D patients' tissues including blood, muscle, liver, pancreas, and adipose tissues, 71% and 60% of these genes were differentially expressed in pancreas (GSE25724) and liver (GSE15653), respectively. A total of 169 genes contain highly conserved motifs for various transcription factors involved in immune response, thereby suggesting coordinated expression. Through co-expression analysis, we obtained three modules. The respective modules had 78, 158, and 55 genes, and <i>TRAF2</i>, <i>HMGA1</i>, and <i>RGS5</i> as hub genes. Further, we used the BioNSi pathways simulation tool and identified the following five KEGG pathways perturbed in four or more tissues, namely Toll-like receptor signaling pathway, RIG-1-like receptor signaling pathway, pathways in cancer, NF-kappa B signaling pathway, and insulin resistance pathway. The genes <i>NFKBIA</i> and <i>IKBKB</i> are common to all these five pathways. In addition, using the NF-κB computational activation model, we identified that the reversal of NF-κB constitutive activation through overexpression of NFKB1 (P50 homodimer), PPARG, PIAS3 could reduce insulin resistance by almost half of its original value. To conclude, co-expression studies, gene expression network simulation, and NF-κB computational modeling substantiate the causal role of NF-κB pathway in insulin resistance.

Further, the strain was used to produce the <i>Magnetospirillum</i> Liquid Biofertilizer (MLB) and analyzed using GC-MS and LC-HRMS to identify beneficial compounds for agriculture. The findings indicated the presence of biostimulant compounds including proline, indole-3-acetic acid, koninginin, and glutamate. Furthermore, different dilutions (20%, 40%, 60%, 80%, and 100%) of MLB were supplemented to <i>V.radiata</i> to explore its nitrogen-fixing capacity, iron enhancement effects, plant growth and yield. Plants treated with 20% MLB exhibited a significant increase in plant length (85.6%), seed weight (74.5%), total chlorophyll content (58.3%), protein (95.91%), leaf nitrogen content (71.72%) compared to the control group treated with distilled water.

This study reports, for the first time, a highly efficient transformation and regeneration protocol for N22 using a CRISPR/Cas9 vector. Mature seeds were used to induce embryogenic calli on CHU(N6)-based callus induction media (CIM) with varying concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D). The highest callus induction efficiency (~ 94%) was achieved using 3 mgL<sup>-1</sup> 2,4-D. For regeneration, calli were transferred to different regeneration media-I (RM-Ia to RM-Ie), where a combination of 5 mgL<sup>-1</sup> 6-benzylaminopurine (BAP) and 0.02 mgL<sup>-1</sup> naphthalene acetic acid (NAA) resulted in ~ 44% regeneration frequency. Subsequent optimisation of regeneration media-II (RM-II) with low NAA concentration enhanced shoot elongation and root development. Furthermore, reducing basal salt concentration in the resuspension media significantly enhanced transformation efficiency to 44%, achieved, by only using sterile distilled water (SDW) with 150 mM acetosyringone for calli infection. The optimised protocol was successfully validated using CRISPR/Cas9 vector, facilitating targeted gene knockouts for functional genomic studies.
