Abstract:
Cancer therapy is moving beyond traditional chemotherapy to include epigenetic approaches. KDM6 demethylases are dynamic regulation of gene expression by histone demethylation in response to diverse stimuli, and thus their dysregulation has been observed in various cancers. In this review, we first briefly introduce structural features of KDM6 subfamily, and then discuss the regulation of KDM6, which involves the coordinated control between cellular metabolism (intrinsic regulators) and tumor microenvironment (extrinsic stimuli). We further describe the aberrant functions of KDM6 in human cancers, acting as either a tumor suppressor or an oncoprotein in a context-dependent manner. Finally, we propose potential therapy of KDM6 enzymes based on their structural features, epigenetics, and immunomodulatory mechanisms, providing novel insights for prevention and treatment of cancers.
Insights
KDM6 demethylases are key epigenetic regulators in cancer, acting as tumor suppressors or oncoproteins. Understanding their regulation and function offers novel therapeutic strategies for cancer prevention and treatment.
Area of Science:
- Oncology
- Epigenetics
- Molecular Biology
Background:
- Cancer therapy is evolving to incorporate epigenetic strategies beyond traditional chemotherapy.
- KDM6 demethylases play a crucial role in regulating gene expression through histone demethylation.
- Dysregulation of KDM6 demethylases is implicated in the development of various human cancers.
Purpose of the Study:
- To review the structural features and regulation of the KDM6 subfamily of demethylases.
- To explore the context-dependent roles of KDM6 enzymes as tumor suppressors or oncoproteins in cancer.
- To propose novel therapeutic strategies targeting KDM6 enzymes for cancer treatment.
Main Methods:

- Review of intrinsic (cellular metabolism) and extrinsic (tumor microenvironment) regulators of KDM6.
- Analysis of KDM6 aberrant functions in human cancers.
- Exploration of epigenetic and immunomodulatory mechanisms related to KDM6.
Main Results:
- KDM6 regulation is influenced by both cellular metabolism and the tumor microenvironment.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
