Systematic Multi-Omics Investigation of Androgen Receptor Driven Gene Expression and Epigenetics changes in Prostate...

Area of Science:

• Oncology
• Molecular Biology
• Genomics

Background:

• Prostate cancer is a prevalent malignancy driven by androgen receptor (AR) signaling.
• Understanding AR signaling is crucial for advancing prostate cancer research and treatment strategies.

Purpose of the Study:

• To conduct a comprehensive multi-omics analysis of AR signaling in the androgen-sensitive LNCaP cell line.
• To investigate the transcriptomic and epigenomic changes induced by androgen deprivation therapy (ADT).

Main Methods:

• Multi-omics data analysis including RNAseq, ATACseq, and ChIPseq from the LNCaP cell line.
• Curation and processing of high-quality public datasets using advanced bioinformatics tools.

Main Results:

• Identified significant gene expression changes (1004 up-regulated, 707 down-regulated) in response to ADT, diminishing AR signaling.
• AR primarily binds to distal enhancers, influencing chromatin accessibility without altering proximal promoters.
• AR signaling impacts pathways including neuron differentiation, cell adhesion, P53 signaling, and inflammation.

Conclusions:

• This study provides a valuable, publicly accessible multi-omics dataset on AR signaling in prostate cancer.
• The findings offer insights into the transcriptomic and epigenomic landscape of prostate cancer under ADT.
• The data serves as a resource for future research into AR-driven prostate cancer mechanisms.
