KRAS and lung adenocarcinoma: In order to test whether FSP1 expression may be upregulated in KRAS-driven cancer, we probed publicly available tumor (TCGA) and normal (GTEX) datasets for FSP1 expression in colorectal cancer, lung adenocarcinoma and pancreatic adenocarcinoma in comparison to their respective normal tissue of origin using Gene Expression Profiling Interactive Analysis (GEPIA).
