Abstract:
Clear cell renal cell carcinoma (ccRCC) is characterized by loss of the von Hippel-Lindau tumor suppressor gene (VHL), and the functional tumorigenic consequences of this loss have been used to develop therapies for advanced ccRCC, such as targeting activation of the HIF pathway. Yao and colleagues elucidate how VHL loss contributes to chromatin alteration at both gene promoters and enhancers/superenhancers, in both an HIF-dependent as well as independent manner, and how this may provide additional targets for therapeutic intervention in advanced ccRCC.

Insights
Loss of the von Hippel-Lindau (VHL) gene in clear cell renal cell carcinoma (ccRCC) alters chromatin. This study reveals VHL loss impacts gene promoters and enhancers, offering new therapeutic targets for advanced ccRCC.
Area of Science:
- Oncology
- Cancer Biology
- Molecular Biology
Background:
- Clear cell renal cell carcinoma (ccRCC) is strongly associated with the loss of the von Hippel-Lindau (VHL) tumor suppressor gene.
- Therapies for advanced ccRCC currently target downstream consequences of VHL loss, such as the hypoxia-inducible factor (HIF) pathway.
Purpose of the Study:
- To investigate the role of VHL loss in chromatin alterations at gene regulatory elements in ccRCC.
- To identify potential novel therapeutic targets beyond HIF pathway activation.
Main Methods:
- Analysis of chromatin accessibility and modifications in ccRCC models with VHL loss.
- Investigation of both HIF-dependent and HIF-independent mechanisms of VHL's effect on chromatin.
Main Results:
- VHL loss induces widespread chromatin alterations at both gene promoters and enhancers/superenhancers.
- These chromatin changes occur through both HIF-dependent and HIF-independent mechanisms.
- Identified specific chromatin alterations that could be targeted therapeutically.
Conclusions:
- VHL loss profoundly impacts the ccRCC epigenome, affecting gene regulation beyond the HIF pathway.
- These VHL-dependent chromatin alterations represent promising new therapeutic targets for advanced ccRCC.

Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
