It is a group of diseases, often resulting from the dysregulation of multiple cellular pathways involved in differentiation, cell proliferation, cell cycle regulation, and DNA repair. These disruptions are primarily caused by genetic mutation and epigenetic alterations which lead to uncontrolled growth and tumor formation. Targeted therapy is a precise and effective strategy to overcome the shortcomings of conventional therapy. RNA interference (RNAi) is a gene-silencing mechanism that has an uncanny ability to target disease-associated genes. Small interfering RNA (siRNA) is a key component of RNAi and has shown promise in silencing oncogenes and inhibiting cancer progression. However, the therapeutic application of siRNA faces several challenges such as poor cellular uptake, short half-life, endosomal escape, immune system activation, and off-target. Strategies to address these challenges are optimized designing of siRNA, advanced delivery systems, and chemical modification to improve cellular uptake and protect from degradation. This review focuses on the therapeutic potential of siRNA in cancer treatment and discusses the action mechanism of siRNA, barriers in siRNA, and strategies to overcome them. The review shed light on the current clinical trial of siRNA-based cancer therapy, along with outcomes and limitations.</div></div>","PeriodicalId":53463,"journal":{"name":"Journal of Genetic Engineering and Biotechnology","volume":"23 2","pages":"Article 100484"},"PeriodicalIF":3.5,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bacteria from tannery wastes are naturally adapted to Cr; eight Cr(III) tolerant bacteria, namely bacterial isolate (BI) 1 to 8, were isolated from the collected waste samples. The isolated bacteria showed the maximum tolerance concentration (MTC) range of 700 to 1500 ppm for Cr(III) and 200 to 600 ppm for Cr(VI). Physiological and biochemical analysis, including the gelatin hydrolysis activity, identified those isolates up to the genus level. Among the isolates, BI 4, 5, and 7 were able to hydrolyze gelatin. Therefore, 16S rRNA molecular characterization was conducted for those isolates, which confirmed BI 4, 5, and 7 as <em>Bacillus wiedmannii</em> (Accession No: OR564007), <em>Enterococcus faecium</em> (Accession No: OR564008), and <em>Bacillus cereus</em> (Accession No: OR564009), respectively.

Immunoinformatics approaches have been utilized for epitope prediction, focusing on B-cell and T-cell epitopes of the Nipah virus nucleoprotein. The multi-epitope vaccine was constructed using linkers and adjuvants to enhance immunogenicity. Structural refinement, molecular docking with human ephrin B2 receptor, and immune simulations were performed to validate the vaccine’s stability, binding efficiency, and immune response potential. The designed multi-epitope vaccine exhibited high antigenicity (0.56), non-allergenicity, and non-toxicity. Docking analysis showed a strong binding affinity with the ephrin B2 receptor (binding energy: −920 kcal/mol). Immune simulations indicated significant immune responses with high IgG and IgM levels and memory B-cell activation. Population coverage analysis revealed a global coverage of 88.3 %, supporting its potential for broad immunization. The designed vaccine against the Nipah virus demonstrates promising antigenicity, stability, and strong binding with the ephrin B2 receptor.
