Unveiling Let-7a's Therapeutic Role in Ewing Sarcoma Through Molecular Docking and Deformation Energy Analysis

Area of Science:

• Oncology
• Molecular Biology
• Bioinformatics

Background:

• Ewing sarcoma is a rare pediatric bone and soft tissue cancer.
• Understanding the molecular mechanisms driving Ewing sarcoma is crucial for developing new therapies.

Purpose of the Study:

• To investigate the role of hsa-let-7a as a target molecule in Ewing sarcoma pathophysiology.
• To explore the potential of hsa-let-7a as a therapeutic candidate using computational methods.

Main Methods:

• Retrieved miRNA (hsa-let-7a) and mRNA (EWSR1) sequences from public databases.
• Predicted 3D structures of hsa-let-7a and EWSR1 mRNA using MC-Fold and RNAComposer.
• Utilized HNADOCK and PatchDock servers for miRNA-mRNA molecular docking.
• Performed anisotropic network model analysis and generated heatmap graphs.

Main Results:

• Docking analysis showed favorable binding scores and interaction profiles between hsa-let-7a and EWSR1 mRNA.
• Anisotropic network model analysis provided insights into nucleotide interactions and fluctuations.
• Heatmap analysis indicated hsa-let-7a's involvement in cellular signaling pathways relevant to Ewing sarcoma.

Conclusions:

• hsa-let-7a demonstrates significant interactions with EWSR1 mRNA, suggesting its role in Ewing sarcoma.
• hsa-let-7a is a promising therapeutic target for Ewing sarcoma based on miRNA-driven predictive modeling.
• Computational approaches offer valuable insights for identifying novel cancer therapeutic strategies.
