Among the 150 ccRCC tissue spots included in the TMA, 147 (98.00%) spots were positive for LPCAT1 (staining in the membrane and cytoplasm of cancer cells), while only 4/30 (13.33%) normal renal tissue spots showed positive signals (staining in the renal tubular) (χ2 test, p < 0.001). This evidence concerns the gene LPCAT1 and nonpapillary renal cell carcinoma.
