The hub genes in males included nine Y chromosome genes and six autosomal genes, while females had six specific genes. Further predictions using the NetworkAnalyst online tool suggested that transcription factors (REST, androgen receptor) and microRNAs (miR-27a-3p, miR-146a-5p) may be involved in regulating the above sex-related hub genes.
