In our data, hsa-miR-21-5p and hsa-miR-92a-3p (the hsa-miR-92a-5p passenger strand) were up-regulated by both T. vaginalis and P. bivia and hsa-miR-146a-5p was up regulated by P. bivia. While in silico analysis fails to correlate hsa-miR-21-5p with proteins assigned to cancer pathways, it links hsa-miR-146a-5p to cancer by targeting ERBB4, a protein enriched in two KEGG terms associated with cancer (‘ErbB signaling pathway’ and ‘proteoglycans in cancer’). The gene discussed is ERBB4; the disease is cancer.
