In Figure 4, F–J, and Supplemental Figure 2, quantitative PCR analysis of the above tumors using human and murine primers that distinguished tumor cell (human) and host cell (mouse) intrinsic gene transcripts were used to evaluate expression of CC-associated cyto/chemokines and other molecules associated with STK11/LKB1 NSCLC gene alterations (4, 11). Here, STK11 is linked to non-small cell lung carcinoma.
