Research Article: FKBP4-HSP90 Interaction in Colorectal Cancer: A Novel Therapeutic Target

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Background:

• Colorectal cancer (CRC) progression involves key molecular pathways like heat shock protein 90 (HSP90), PI3K/AKT, TP53, and mismatch repair (MMR).
• Identifying novel biomarkers and therapeutic targets is crucial for improving CRC patient outcomes.

Purpose of the Study:

• To investigate the role of FKBP4 in colorectal cancer.
• To explore the association between FKBP4 and HSP90 in CRC.
• To evaluate the FKBP4-HSP90 interaction as a potential therapeutic target for CRC.

Main Methods:

• Analysis of FKBP4 expression in CRC patient samples at transcript and translational levels.
• STRING network analysis to identify associations between FKBP4 and other proteins.
• Utilizing TCGA CRC patient data to assess correlations between FKBP4 and HSP90.
• Employing molecular docking, dynamics simulations, and hydrogen bond analysis to confirm FKBP4-HSP90 interactions.

Main Results:

• FKBP4 was found to be overexpressed in CRC patient samples.
• A strong association and positive correlation were identified between FKBP4 and HSP90.
• Molecular simulations confirmed a significant interaction between FKBP4 and HSP90, highlighting its role in CRC cell survival and progression.

Conclusions:

• FKBP4 may serve as a predictive biomarker for CRC diagnosis.
• The FKBP4-HSP90 complex plays a critical role in colorectal cancer progression.
• Disrupting the FKBP4-HSP90 interaction presents a promising therapeutic strategy for CRC treatment.
