Designing potential siRNA molecules for silencing the gene of the nucleocapsid protein of Nipah virus: A computational investigation
Infect Genet Evol. 2022 May 27:105310. doi: 10.1016/j.meegid.2022.105310. Online ahead of print.ABSTRACTNipah virus (NiV), a zoonotic virus, engenders severe infections with noticeable complications and deaths in humans and animals. Since its emergence, it is frightening that this virus has been causing regular outbreaks in various countries, particularly Bangladesh, India, and Malaysia. Unfortunately, no efficient vaccine or drug is available to combat this baneful virus. It employs the nucleocapsid protein in its genetic material encapsidation, which is a crucial for viral replication. The small interfering RNAs (siRNAs)...

Designing an effective therapeutic siRNA to silence RdRp gene of SARS-CoV-2
Infect Genet Evol. 2021 Jun 2:104951. doi: 10.1016/j.meegid.2021.104951. Online ahead of print.ABSTRACTThe devastating outbreak of COVID-19 has spread all over the world and has become a global health concern. There is no specific therapeutics to encounter the COVID-19. Small interfering RNA (siRNA)-based therapy is an efficient strategy to control human viral infections employing post-transcriptional gene silencing (PTGS) through neutralizing target complementary mRNA. RNA-dependent RNA polymerase (RdRp) encoded by the viral RdRp gene as a part of the replication-transcription complex can be adopted as an acceptable targe...

Bioinformatics analysis reveals four major hexon variants of human adenovirus type-3 (HAdV-3) as the potential strains for development of vaccine and siRNA-based therapeutics against HAdV-3 respiratory infections.
This study was designed to evaluate HAdV-3 hexon variants for the selection of potential vaccine candidates and the use of hexon gene as a target for designing siRNA that can be used as a therapy. Based on the data of worldwide distribution, duration of circulation, co-circulation and their percentage among all the variants, 3Hv-1 to 3Hv-4 were categorized as the major hexon variants. Phylogenetic analysis and the percentage of homology in the hypervariable regions followed by multi-sequence alignment, zPicture analysis and restriction enzyme analysis were carried out. In the phylogram, the variants were arranged in differ...

Patterns of molecular evolution of RNAi genes in social and socially parasitic bumblebees.
Abstract The high frequency of interactions amongst closely related individuals in social insect colonies enhances pathogen transmission. Group-mediated behavior supporting immune defenses tend to decrease selection acting on immune genes. Along with low effective population sizes this might result in relaxed constraint and rapid evolution of immune system genes. Here, we show that antiviral siRNA genes show high rates of molecular evolution with argonaute 2, armitage and maelstrom evolving faster in social bumblebees compared to their socially parasitic cuckoo bumblebees that lack a worker caste. RNAi genes show ...

Inflammasome signaling pathways exert antiviral effect against Chikungunya virus in human dermal fibroblasts.
Abstract Arboviruses represent an emerging threat to human. They are transmitted to vertebrates by the bite of infected arthropods. Early transmission to vertebrates is initiated by skin puncture and deposition of virus in this organ. However, events at the bite site remain largely unknown. Here, we report that Chikungunya virus (CHIKV) and West Nile virus (WNV), despite belonging to distinct viral families, elicit a common antiviral signature in primary human dermal fibroblasts, attesting for the up regulation of interferon signalling pathways and leading to an increased expression of IFN-β, interleukins and che...

Inhibition of porcine reproductive and respiratory syndrome virus by specific siRNA targeting Nsp9 gene.
Abstract To screen siRNAs for effectively inhibiting the replication of porcine reproductive and respiratory syndrome virus (PRRSV).Four pairs of siRNA targeting Nsp9 gene of PRRSV and one non-efficient pair used as control were designed, synthesized and cloned into pSilencer4.1-CMV neo, designated as pSi-294, pSi-367, pSi-409, pSi-1488, pSi-Ctr. The recombinant plasmids were transfected into Marc-145 cells and infected with PRRSV 24h post transfection. Subsequently, IFA, real-time PCR, TCID50 and western blot were used for evaluating the inhibitory effect of the siRNA. IFA and western-blot results showed that pSi...
