Our results indicated that both MEF2C and MIG6 could be upregulated in gefitinib-resistant cancer tissues and cancer cell lines compared with gefitinib-sensitive ones.
Loss of Mig6 is a driving event in human cancer; analysis of 1,057 gliomas reveals frequent focal deletions of ERRFI1, the gene that encodes Mig6, in EGFR-amplified glioblastomas.
Here we will highlight recent discoveries on the role of Mig-6 in stress response, tissue homeostasis, and cancer development; review the transcriptional regulation of Mig-6 expression; share insight into its mechanism in regulating signal transduction; and discuss the paradox of its action modes under different pathophysiological conditions.
