In another recent study, Wang et al. [164] reported differentially expressed circRNAs in lipopolysaccharide-induced mastitis using bovine mammary epithelial cells (bMECs) and found two novel circRNAs (named novel_circ_0004830 and novel_circ_0003097 in the study) which may endogenously regulate bovine mastitis by binding to inflammation-related microRNAs such as the bta-miR-145 that has been reported to regulate S. aureus-induced mastitis in MAC-T cells by regulating the FSCN1 gene expression level [121]. The gene discussed is FSCN1; the disease is mastitis.
