Furthermore, MFHAS1, reported to promote the progress of cancer,36 was regulated by MYCN. Interestingly, both MYCN and MFHAS1 may be targets of miR-429, which implied miR-429-MYCN-MFHAS1 may form an FFL taking part in the progress of T-ALL (Figure 5B). The gene discussed is MFHAS1; the disease is cancer.
