The experimental results showed that compared with the model control group, the expression of autophagy-related proteins LC3 and beclin-1 were significantly upregulated and that of the proliferation-related protein PCNA was significantly downregulated, which were consistent with the effects of the previous cell experiment (Figures 5(a)–5(c)), further confirming the induction of NSCLC cells autophagy by patchouli alcohol. The gene discussed is MAP1LC3A; the disease is non-small cell lung carcinoma.
