Inhibition of heat shock protein 47 suppressed collagen production in Tenon's capsule fibroblasts
CONCLUSIONS: HSP47 siRNA inhibits the production of COLI in rat Tenon's fibroblasts, and may be the potential therapeutic method in bleb scarring after glaucoma filtration surgery.PMID:37724035 | DOI:10.5603/fhc.96514

HBSP improves kidney ischemia-reperfusion injury and promotes repair in properdin deficient mice via enhancing phagocytosis of tubular epithelial cells
Phagocytosis plays vital roles in injury and repair, while its regulation by properdin and innate repair receptor, a heterodimer receptor of erythropoietin receptor (EPOR)/β common receptor (βcR), in renal ischaemia-reperfusion (IR) remains unclear. Properdin, a pattern recognition molecule, facilitates phagocytosis by opsonizing damaged cells. Our previous study showed that the phagocytic function of tubular epithelial cells isolated from properdin knockout (PKO) mouse kidneys was compromised, with upregulated EPOR in IR kidneys that was further raised by PKO at repair phase. Here, helix B surface peptide (HBSP), derive...

Short interfering RNA in colorectal cancer: is it wise to shoot the messenger?
This study focuses on many innovative siRNA therapies and methodologies for delivering siRNA therapeutics to the malignant site safely and effectively for the treatment of CRC. Treatment of CRC using siRNA-associated nanoparticles (NPs) may inhibit the activity of oncogenes and MDR-related genes by targeting a range of signaling mechanisms. This study summarizes several siRNAs targeting signaling molecules, as well as the therapeutic approaches that might be employed to treat CRC in the future.PMID:37011722 | DOI:10.1016/j.ejphar.2023.175699

siRNAs pools generated in Escherichia coli exhibit strong RNA-interference activity against influenza virus genomic sequences
Virology. 2022 Dec 31;579:38-45. doi: 10.1016/j.virol.2022.12.013. Online ahead of print.ABSTRACTDue to the recurrent pandemic outbreaks that occurred during the last century, Influenza A viruses are considered a serious potential danger to human health. Among the innate immune pathways in eukaryotes, RNA interference plays a significant role in the interaction between viruses and host cells. RNA interference is addressed by small dsRNA molecules produced by the host itself (miRNAs, i.e. "micro-RNAs") but can be triggered also by the administration of exogenous short RNAs (siRNAs, "short interfering RNAs"). In this work, a...

Both LmDicer-1 and two LmDicer-2s participate in siRNA-mediated RNAi pathway and contribute to high gene silencing efficiency in Locusta migratoria
In this study, we identified one LmDicer-1 and two LmDicer-2 (LmDicer-2a and LmDicer-2b) genes in Locusta migratoria. The RNAi of RNAi assay showed that knockdown of each of the Dicer genes reduced RNAi efficiency against a target gene (Lmβ-Tubulin), suggesting that all these genes participated in the siRNA-mediated RNAi pathway. Sequence analyses of the siRNAs generated from dsLmβ-Tubulin after silencing each LmDicer gene showed no significant difference in the pattern of siRNAs mapped to dsLmβ-Tubulin. This result indicated that all the three LmDicers are capable of generating siRNAs from the dsRNA. We then generated ...

Persistent Escherichia coli infection in renal tubular cells enhances calcium oxalate crystal-cell adhesion by inducing ezrin translocation to apical membranes via Rho/ROCK pathway
In this study, Escherichia coli, the most common bacterium found in recurrent UTI was used to establish the in vitro model for persistent infection of renal epithelial cells. The promoting effects of persistent E. coli infection on kidney stone formation were validated by COM crystal-cell adhesion assay, followed by immunofluorescence study for changes in surface expression of the known COM crystal receptors. Among the five receptors examined, only ezrin had significantly increased level on the surface of persistently infected cells without change in its total level. Such translocation of ezrin to apical membranes was conf...

In Vitro Method for Synthesis of Large-Scale dsRNA Molecule as a Novel Plant Protection Strategy
Methods Mol Biol. 2022;2408:211-226. doi: 10.1007/978-1-0716-1875-2_14.ABSTRACTDouble-stranded RNA (dsRNAs) molecules are the precursors and effective triggers of RNAi in most organisms. RNAi can be induced by the direct introduction of dsRNAs in plants, fungi, insects, and nematodes. Until now RNAi is usually established by transformation of the plant with a construct that produces hairpin RNAs. Alternatively, advances in RNA biology demonstrated efficiently the in vitro method of large-scale synthesis of dsRNA molecule. Here we describe the de novo synthesis of dsRNA molecule targeting the specific gene of interest for f...

Molecules, Vol. 27, Pages 1936: A Comprehensive Computational Investigation into the Conserved Virulent Proteins of Shigella species Unveils Potential Small-Interfering RNA Candidates as a New Therapeutic Strategy against Shigellosis
In this study, we analyzed 264 conserved sequences from 15 different conserved virulence genes of Shigella sp., through extensive rational validation using a plethora of first-generation and second-generation computational algorithms for siRNA designing. Fifty-eight siRNA candidates were obtained by using the first-generation algorithms, out of which only 38 siRNA candidates complied with the second-generation rules of siRNA designing. Further computational validation showed that 16 siRNA candidates were found to have a substantial functional efficiency, out of which 11 siRNA candidates were found to be non-immunogenic. Fi...
