Von Hippel-Lindau (VHL) is an important tumor suppressor that is lost in the majority of clear
cell carcinoma of renal cancer (ccRCC). Its regulatory pathway involves the activity of E3
ligase, which targets hypoxia inducible factor α (including HIF1α and HIF2α) for proteasome
degradation. In recent years, emerging literature suggests that VHL also possesses other
HIF-independent functions. This review will focus on VHL-mediated signaling pathways

Von Hippel-Lindau (VHL) is an important tumor suppressor that is lost in the majority of clear cell carcinoma of renal cancer (ccRCC). Its regulatory pathway involves the activity of E3 ligase, which targets hypoxia inducible factor α (including HIF1α and HIF2α) for proteasome degradation. In recent years, emerging literature suggests that VHL also possesses other HIF-independent functions. This review will focus on VHL-mediated signaling pathways involving the latest identified substrates/binding partners, including N-Myc downstream-regulated gene 3 (NDRG3), AKT, and G9a, etc., and their physiological roles in hypoxia signaling and cancer. We will also discuss the crosstalk between VHL and NF-κB signaling. Lastly, we will review the latest findings on targeting VHL signaling in cancer.
