This was confirmed at the protein level by immunohistochemistry (IHC) for ZFP36L1 using human lung tumor tissue microarrays (TMAs) where ZFP36L1 protein levels were significantly lower in SCLC TMAs compared to lung adenocarcinoma TMAs (Fig. 3c, d). The gene discussed is ZFP36L1; the disease is lung adenocarcinoma.
