GenomeJack

GenomeJack analyzes nuclear respiratory factor 1 (NRF1) ChIP-Seq data to identify NRF1 target genes and characterize their roles in mitochondrial biogenesis, mitochondrial function, and potential involvement in neurodegenerative diseases.

Key Features:

• NRF1 target gene identification: Uses stringent ChIP-Seq peak analysis on datasets (including ENCODE) to identify NRF1-bound protein-coding genes from SK-N-SH human neuroblastoma cells.
• Promoter-proximal peak detection: Identifies highly stringent peaks accumulated in proximal promoter regions that contain an NRF1-binding consensus sequence.
• Pathway enrichment analysis: Determines enrichment of NRF1 target genes in mitochondrial respiratory function and extra-mitochondrial processes including RNA metabolism, splicing, cell cycle regulation, DNA damage repair, translation initiation, and ubiquitin-mediated protein degradation.
• Disease-relevant gene discovery: Reports NRF1 targets implicated in neurodegenerative diseases, including PARK2 (Parkin), PARK6 (Pink1), PARK7 (DJ-1), PAELR (GPR37) for Parkinson's disease, and PSENEN (Pen2) and MAPT (tau) for Alzheimer's disease.

Scientific Applications:

• Neurodegenerative disease mechanism discovery: Enables investigation of how NRF1-regulated genes contribute to the molecular pathology of Parkinson's disease and Alzheimer's disease.
• Mitochondrial biology studies: Supports analysis of genes involved in mitochondrial biogenesis and respiratory function regulated by NRF1.
• Gene regulatory network analysis: Facilitates exploration of NRF1-centered regulatory networks affecting RNA metabolism, cell cycle, DNA repair, translation initiation, and ubiquitin-mediated degradation.

Methodology:

Analysis of ChIP-Seq datasets (e.g., ENCODE) with highly stringent peak calling focused on protein-coding genes in SK-N-SH cells, emphasizing peaks in proximal promoter regions with an NRF1-binding consensus sequence.
