YBX1 and non-small cell lung carcinoma: To further confirm the involvement of YBX1 in autophagy-mediated NSCLC survival, we examined the expression of YBX1 and LC3I/II in clinical lung tumor tissue samples and analyzed the relationship of these proteins with the prognosis of patients with 100 NSCLC using IHC assay (Fig. 6a), and 48 (48%) patients showed high expression of YBX1, 43 (43%) patients showed high expression of LC3I/II.
