TIAM1 and small cell lung carcinoma: TIAM1 gene expression positively correlated with NE score (Figures 1C, S1B, and S1G) and was higher in SCLC tumors, CDXs, or cell lines classified as NE compared to non-NE (Figures 1D, S1C, and S1H), confirming the association between TIAM1 and NE gene expression.
