Bifaceted functions of histone methyltransferases

Area of Science:

• Biochemistry
• Molecular Biology
• Cancer Research

Background:

• Enhancer of Zeste Homolog 2 (EZH2) and SET and MYND-domain containing 3 (SMYD3) are key histone methyltransferases.
• These enzymes exhibit dual roles as gene transcription activators and repressors.
• Their dysregulation is implicated in various cancers.

Purpose of the Study:

• To provide an overview of EZH2 and SMYD3 functions in cancer.
• To highlight the significance of understanding their bifaceted regulatory mechanisms.
• To identify rational pharmaceutical strategies for targeting these enzymes.

Main Methods:

• Literature review and perspective synthesis.
• Analysis of the dual roles of EZH2 and SMYD3 in gene transcription.
• Evaluation of potential therapeutic targeting strategies.

Main Results:

• EZH2 and SMYD3 possess complex roles in cancer gene regulation.
• Understanding their bifaceted functions is crucial for effective cancer therapy.
• Protein and mRNA degradation pathways present promising therapeutic platforms.

Conclusions:

• Targeting the bifaceted nature of EZH2 and SMYD3 is essential for novel cancer pharmacologic interventions.
• Pharmaceutical strategies focusing on protein or mRNA degradation offer a biologically rational approach.
• Further research into these mechanisms can lead to improved cancer treatments.
