Petits ARN interf érents : applications potentielles pour les néphrologues Small interfering RNA: potential applications for nephrologists
Nephrol Ther. 2022 Dec;18(6S1):6S1-6S6. doi: 10.1016/S1769-7255(22)00646-0.ABSTRACTSmall interfering RNA (siRNAs) are double-stranded RNAs of around 20 base pairs in length that trigger RNAi machinery, which promotes degradation of a target mRNA avoiding protein translation. SiRNAs are liver-targeted, using tris N-acetylgalactosamine (GalNAc) as the targeting ligand. This discovery received the Nobel Prize for medicine and physiology in 2006 and lead to substantial therapeutic advances. Application field and development of these siRNA has been very fast. Indeed, patisiran has been released in 2018 for hereditary transthyre...

Novel Complement C5 Small-interfering RNA Lipid Nanoparticle Prolongs Graft Survival in a Hypersensitized Rat Kidney Transplant Model
Conclusions. C5 siRNA-LNP combined with immunosuppressants CsA and DSG downregulated C5 activity and significantly prolonged graft survival compared with control siRNA-LNP with CsA and DSG. Downregulation of C5 expression using C5 siRNA-LNP may be an effective therapeutic approach for AMR.

Tumor and stroma COL8A1 secretion induces autocrine and paracrine progression signaling in pancreatic ductal adenocarcinoma
Matrix Biol. 2022 Nov 11:S0945-053X(22)00134-2. doi: 10.1016/j.matbio.2022.11.002. Online ahead of print.ABSTRACTSeveral collagen subtypes are involved in pancreatic ductal adenocarcinoma (PDAC) desmoplasia, which constrains therapeutic efficacy. We evaluated collagen type VIII alpha 1 chain (COL8A1), whose function in PDAC is currently unknown. We identified COL8A1 expression in 7 examined PDAC cell lines by microarray analysis, western blotting, and RT‒qPCR. Higher COL8A1 expression occurred in 2 gemcitabine-resistant PDAC cell lines; pancreas tissue (n=15) from LSL-KrasG12D/+; Pdx-1-Cre mice with advanced PDAC predisp...

Cyclophilin A/CD147 signaling induces the epithelial-to-mesenchymal transition and renal fibrosis in chronic allograft dysfunction by regulating p38 MAPK signaling
CONCLUSIONS: Our study reported the positive relationship of CyPA-CD147 signaling with renal allograft dysfunction. The in vitro study suggested that CyPA-CD147 signaling induce the development of the EMT process by p38 MAPK signaling, thus contributing to renal allograft fibrosis and CAD.PMID:36203223 | DOI:10.1080/0886022X.2022.2126788
