Potential liquid biopsy markers of exosomal microRNAs in renal interstitial fibrosis blood and urine.
Indian J Pathol Microbiol
October 2024
Department of Pathology, Sichuan Taikang Hospital, Chengdu, China.
Objective: To explore more and better liquid biopsy markers of exosomal microRNAs (exo-miRNAs) in renal interstitial fibrosis (RIF) and to preliminary investigate the biological functions and signaling pathways involved in these markers.
Materials And Methods: High-throughput miRNA sequencing was performed on blood and urine exo-miRNAs from three RIF patients and three healthy volunteers, and differential expression analysis and bioinformatic processing were performed.
Results: There were 13 differentially expressed exo-miRNA (DEexo-miRNA) between RIF and healthy blood, and 20 DEexo-miRNAs in urine.
miRNA Expression Profile in Primary Limbal Epithelial Cells of Aniridia Patients.
Invest Ophthalmol Vis Sci
January 2025
Dr. Rolf M. Schwiete Center for Limbal Stem Cell and Congenital Aniridia Research, Homburg/Saar, Germany, Saarland University, Homburg/Saar, Germany.
Purpose: This study evaluates the microRNA (miRNA) expression profile in primary limbal epithelial cells (pLECs) of patients with aniridia.
Methods: Primary human LECs were sampled and isolated from 10 patients with aniridia and 10 healthy donors. The miRNA profile was analyzed using miRNA microarrays.

Oregon Health & Science University, Portland, OR, USA.
Background: Alzheimer's disease (AD) is the most common cause of dementia, and the fifth leading cause of death for those 65 and older. Brain changes in AD begin 10-20 years before symptoms appear, yet markers for early brain changes are lacking. We discovered and validated miRNAs in human cerebrospinal fluid (CSF) that differentiate AD from Controls.

Our approach is based on targeted selection and quantitative analysis of microRNAs enriched in the brain and detectable in blood plasma. Here, we report the comparative analysis of 24 microRNAs comprising CogniMIR panel in 200 plasma samples with our Gen1 and Gen2 software algorithms towards distinguishing cognitively unimpaired (CU), MCI and AD cohorts.

Aims: Gestational diabetes mellitus (GDM) provides offspring with a hyper-metabolic intrauterine microenvironment. In this study, we aimed to identify key differential microRNAs in GDM-derived exosomes and explore the potential mechanisms of abnormal embryonic development of islets in offspring.
Main Methods: Exosomes were extracted from umbilical vein blood of GDM and non-GDM (NGDM) parturients for microRNA sequencing.
