MICA and small cell lung carcinoma: Further, we found MICA and MICB, the most widely expressed NKG2DL, on SCLC-N cells were suppressed by MYC (Figure 2 and Figure S2), whose encoded protein, c-Myc, was higher expressed in SCLC-N cells than in other types of SCLC cells [8], indicating the key role of MYC in the immune characteristics of SCLC.
