circAMN1/miR-205_R-1/SLC39A8 axis regulates ferroptosis in endometrial epithelial cells and regulates the occurrence of retained placenta in cows

In this study, we performed RNA-sequencing to characterize the expression profiles of circRNAs in caudal vein blood samples of postpartum Holstein cows whose fetal membranes were discharged normally or retained to identify retained placenta (RP)-related genes and evaluate their molecular mechanisms. Comparative gene expression profiling analysis of RNA-seq data for caudal vein blood samples of postpartum Holstein cows whose fetal membranes were discharged normally (NC) or retained (n=3).
