The authors suggested that the alteration of miRNA levels may contribute to the upregulation of genes involved in the androgen signalling pathway, such as macrophage colony-stimulating factor (CSF-1), macrophage colony-stimulating factor receptor (CSF-1R), and Erb-B2 receptor tyrosine kinase 4 (ErbB4), during the initial stages of ovarian cancer [72]. The gene discussed is ERBB4; the disease is ovarian carcinoma.
