We have confirmed that LINC00944 was highly expressed in RCC tissues, so we used qRT-PCR to detect the expression of LINC00944 in six human renal carcinoma cell lines with different malignant potentials (ACHN, Caki-2, Caki-1, 769-P, 786-O, and OSRC) and one human normal renal tubular epithelial cell line HK-2. The gene discussed is LINC00944; the disease is renal cell carcinoma.
