Abstract

Insights

Basil polysaccharides show potential in inhibiting key epigenetic targets linked to breast cancer. This study used molecular docking to identify specific polysaccharides that bind effectively to histone deacetylases (HDACs) and histone acetyltransferases (HATs), offering new avenues for breast cancer research.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Pharmacology

Background:

  • Breast cancer (BC) is a leading cancer in women, often linked to epigenetic dysregulation.
  • Histone deacetylases (HDACs) and histone acetyltransferases (HATs) are critical epigenetic targets in cancer, including BC.
  • Basil (Ocimum basilicum) possesses known anti-cancer properties, but its polysaccharides' effects on epigenetic targets are unclear.

Purpose of the Study:

  • To investigate the binding potential of basil polysaccharides (BPSs) against key epigenetic targets implicated in breast cancer.
  • To explore the molecular interactions between BPSs and specific HDACs and HATs using computational methods.

Main Methods:

  • Utilized molecular docking studies to screen various BPSs against a panel of breast cancer-related epigenetic targets (HDAC1-8 and HAT).
  • Conducted swissADME studies to assess the drug-likeness and pharmacokinetic properties of the BPSs.

Main Results:

  • Several BPSs, including glucosamine (ring and linear), glucuronic acid (linear and ring), rhamnose (linear), galactose (ring), mannose, glucose, and xylose, demonstrated consistent binding affinity.
  • These BPSs showed potential interactions with HDAC1, HDAC2, HDAC4, HDAC5, HDAC6, HDAC7, HDAC8, and HAT, all relevant to BC pathogenesis.

Conclusions:

  • This study provides the first report on the binding of BPSs to these specific epigenetic targets in breast cancer.
  • The findings suggest that BPSs could serve as novel inhibitors for epigenetic targets in BC, warranting further experimental validation.
  • Understanding these molecular mechanisms can guide the development of new therapeutic strategies for breast cancer.
