    Article Snippet: Proteins were transferred to PVDF membranes using a semidry blotter (Bio-Rad) and incubated in a blocking solution (5% nonfat dry milk in TBS containing 0.1% Tween-20) for 1 hour to reduce nonspecific binding. .. Immunoblots were performed using anti-GAPDH, pCXCL12, AKT, pAKT, ERK, pERK, NOTCH1, NOTCH2, and NOTCH3 antibodies (1:1000) followed by goat anti-rabbit secondary antibodies, conjugated to horseradish peroxidase (1:2000) in 5% milk (Santa Cruz Biotechnology). .. Western blots were developed using an enhanced chemiluminescence detection assay following the manufacturer's directions (BioRad).

    A proposed model illustrating the exosome-mediated lncRNA OTUD6B-AS1/miR-128/Notch2 axis in aggravating endometritis. Upon LPS-induced damage, endometrial epithelial cells (EECs) release increased exosomes carrying elevated levels of lncRNA OTUD6B-AS1. These exosomes are taken up by endometrial macrophages. The transferred lncRNA OTUD6B-AS1 acts as a molecular sponge to sequester miR-128, leading to the derepression and upregulation of its target gene, Notch2. The enhanced Notch2 signaling subsequently promotes macrophage polarization towards a pro-inflammatory M1 phenotype, characterized by increased NF-κB activation and iNOS expression, thereby exacerbating endometrial inflammation and tissue damage.
