Fig. 6From: Interplay between lncRNA RP11-367G18.1 variant 2 and YY1 plays a vital role in hypoxia-mediated gene expression and tumorigenesisRP11-367G18.1 variant 2–YY1 complex is essential for hypoxia-induced tumorigenicity. (A) Knockdown of YY1 decreased the colony formation of FADU cells overexpressing RP11-367G18.1 variant 2. (B) Knockdown of RP11-367G18.1 variant 2 suppressed the colony formation of FADU cells overexpressing YY1. (C) Knockdown of RP11-367G18.1 variant 2 or YY1 suppressed the colony formation of H1299 cells overexpressing HIF-1α (ΔODD). (D) Knockdown of RP11-367G18.1 variant 2 or YY1 suppressed HIF-1α (ΔODD)-enhanced tumor volume of FADU cell-derived xenografts. Scr, Scrambled; Cont, control; V2, variant 2.
