(a) Positive expression of INSR in NSCLC tissues. (b) Negative expression of INSR in NSCLC tissues. (c) Negative expression of INSR in adjacent normal tissues. (d) Positive expression of IRS-1 in NSCLC tissues. (e) Negative expression of IRS-1 in NSCLC tissues. (f) Negative expression of IRS-1 in adjacent normal tissues. (g) Positive expression of PD-L1 in NSCLC tissues. (h) Negative expression of PD-L1 in NSCLC tissues.
