Previous research has also shown that the CYP4Z2P pseudogene and the 3′UTR of the CYP4Z1 gene collectively enhance breast cancer angiogenesis by activating the PI3K and extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathways, functioning as ceRNAs for CYP4Z1.150. The gene discussed is CYP4Z1; the disease is breast carcinoma.
