BMP2 and nonpapillary renal cell carcinoma: The expression of lncRNAs was successfully validated for upregulated (lnc-BMP2-2, lnc-CPN2-1, lnc-FZD1-2, lnc-ITPR2-3, lnc-SLC30A4-1, lnc-SPAM1-6), downregulated (lnc-ACACA-1, lnc-FOXG1-2, lnc-LCP2-2, lnc-RP3-368B9, lnc-TTC34-3), and unregulated (lnc-ERCC5-1, lnc-RP11-480I12.4.1-1) transcripts using qPCR in a cohort of 55 ccRCC and 52 normal renal specimen, thus the specificity of the microarray results is confirmed.
