Next Generation Sequencing of 786-O-Ctrl and786-O-VHL Transcriptomes

Inactivation of the E3 ubiquitin ligase protein von Hippel-Lindau (VHL) is critical to clear cell renal cell carcinomas (ccRCC) and VHL syndrome. VHL loss leads to stabilization of hypoxia-inducible factor α (HIFα) and other substrate proteins, which may drive various tumor-promoting pathways. This process is likely reversible, because even in the highly aggressive human VHL-deficient ccRCC cell line 786-O, restoring VHL expression almost completely abolishes orthotopic tumor formation in immuno-deficient mice. This result highlights the potential of treating ccRCC by re-expressing VHL with gene therapy. However, there is inadequate understanding of the consequence of VHL restoration at the molecular level. Here, we reinstalled VHL expression in 786-O and performed transcriptome, proteome and ubiquitome profiling to assess the molecular impact. Transcriptomic profiles of 786-O-TR-Ctrl and 786-O-TR-VHL
