PELI1 and systemic lupus erythematosus: To further confirm whether PELI1 involves the regulation of miR-301a-3p on SLE, the inhibitors of miR-301a-3p and si-PELI1 were cotransfected into the PBMCs of the patients, and the change of the inflammatory factors in the PBMCs of the patients was observed by ELISA.
