GAS5 and renal cell carcinoma: Earlier studies linked aberrant expression of individual lncRNAs to RCC in small-scaled studies (n ≤ 12; i.e. GAS5, also termed SERPINC1 [8,14]; aHIF [15]; MALAT1 [8]); we could not confirm GAS5 downregulation in our microarray study; aHIF and MALAT1 was not deregulated.
