ERBB4 and non-small cell lung carcinoma: Other evidence of miR-193a association with PI3K/Akt has been shown in non-small-cell lung cancer, where it suppresses metastasis by targeting the receptor tyrosine-protein kinase ERBB4, a member of the epidermal growth factor (EGF) receptor subfamily, and inhibiting the downstream PI3K/Akt cascade [52].
