SLC14A1 and neoplasm: Figure 2b illustrates its gene expression profile across all tumor samples and paired normal tissues, revealing that SLC14A1 gene expression levels in kidney chromophobe (KICH), kidney renal clear cell carcinoma (KIRC), and kidney renal papillary cell carcinoma (KIRP) tissues (red) are significantly lower than that in normal renal tissue (brown, Fig. 2b).
