MARCHF8 and non-small cell lung carcinoma: Overexpression of MARCH8 has been found to inhibit NSCLC cell proliferation and metastasis via the phosphoinositide 3-kinase and mTOR signaling pathways.15 Consistently, in our present study, we verified that the cytoplasmic expression of MARCH8 in NSCLC tissues was lower than that in normal lung tissues.
