Epigenetic Profiling of Curcumin on Histone Signatures in Breast Cancer using 3D Network

Area of Science:

• Epigenetics and Cancer Biology
• Neuropharmacology
• Computational Biology

Background:

• Aberrant epigenetic alterations drive cancer development and can be reversed, making them therapeutic targets.
• Curcumin exhibits anticancer and neuroprotective effects through epigenetic regulation, but its mechanisms are unclear.
• Chemotherapy-induced peripheral neuropathy (CIPN) is a significant concern in breast cancer treatment.

Purpose of the Study:

• To investigate curcumin's epigenetic modifications and associated signaling pathways in breast cancer using a 3D network model.
• To identify novel histone codes and phosphoprotein signatures linked to curcumin's effects.
• To explore the relevance of these findings to dorsal root ganglion (DRG) gene expression and neuropathy management.

Main Methods:

• Utilized a 3D network model to analyze multi-omic data from the NIH LINCS program.
• Profiled histone codes modified by curcumin and identified associated phosphoproteins.
• Correlated epigenetic signatures with gene expression in the dorsal root ganglion (DRG).

Main Results:

• Identified two novel histone codes associated with curcumin's action.
• Discovered 23 phosphoproteins mediating these epigenetic changes through cell signaling.
• Linked these signatures to genes expressed in the dorsal root ganglion (DRG).

Conclusions:

• Curcumin's epigenetic modifications involve specific histone codes and phosphoprotein pathways.
• Identified potential biomarkers for chromatin-targeted therapies in breast cancer.
• Proposed new strategies for managing neuropathy in breast cancer patients.
