MicroRNAs are small regulatory molecules that control gene expression. An emerging property of muscle miRNAs is the cooperative regulation transcriptional and epitranscriptional events controlling phenotype. miR-155 has been related to muscular dystrophy cell atrophy. However, function its molecular targets in dystrophies remain poorly understood. Through silico vitro approaches, we identify distinct profiles induced by miR-155-5p cells. The treated myotubes changed expression 359 genes (166...

Coronavirus disease 2019 (COVID-19) presents a wide spectrum of symptoms, the causes which remain poorly understood. This study explored associations between autoantibodies (AABs), particularly those targeting G protein-coupled receptors (GPCRs) and renin‒angiotensin system (RAS) molecules, clinical manifestations COVID-19. Using cross-sectional analysis 244 individuals, we applied multivariate variance, principal component analysis, multinomial regression to examine relationships AAB levels...

Interleukin-6 (IL-6) is a pro-inflammatory cytokine associated with skeletal muscle wasting in cancer cachexia. The control of gene expression by microRNAs (miRNAs) involves the regulation thousands target transcripts. However, miRNA-target networks IL6-induced atrophy remain to be characterized. Here, we show that IL-6 promotes C2C12 myotubes and changes 20 miRNAs (5 up-regulated 15 down-regulated). Gene Ontology analysis predicted targets revealed post-transcriptional genes involved cell...

ABSTRACT The coronavirus disease 2019 (COVID-19) displays a broad spectrum of symptoms, with the underlying reasons for this variability still not fully elucidated. Our study investigates potential association between specific autoantibodies (AABs), notably those that targeting G protein-coupled receptors (GPCRs) and renin-angiotensin system (RAS) related molecules, diverse clinical manifestations COVID-19, commonly observed in patients autoimmune conditions, including rheumatic diseases,...
