Project description:This study investigates the gut microbiome composition and diversity in three groups of rats: control, radiation enteritis model, and treatment (TG) groups. Total DNA was extracted from stool samples, PCR-amplified targeting 16S rRNA gene variable regions, and sequenced using Illumina MiSeq or NovaSeq platforms. Downstream bioinformatics analyses included sequence quality control, denoising (DADA2/OTU clustering), taxonomic classification, alpha and beta diversity evaluation, differential species abundance analysis, and functional prediction. The processed data include ASV/OTU tables, taxonomy assignments, and sample metadata.
Project description:Preeclampsia is one of the most common pregnancy disorders, and characterized by insufficient trophoblast invasion and placental inflammation. RNA sequencing was performed using placental tissues collected from PE patients and control healthy pregnant women. The results showed that OTU deubiquitinase, ubiquitin aldehyde binding 2 (OTUB2) was downregulated in placenta from PE patients.
