mtROS effects on TFAM and mtDNA in HK2 cells

Exploratory Score: 0.900 Price: $0.50 acute kidney injury HK2 cells Status: proposed

What This Experiment Tests

Exploratory experiment designed to discover new patterns targeting TFAM in HK2 cells. Primary outcome: TFAM levels, mtDNA copy number, mitochondrial respiration, cytokine release

Description

In vitro study using human kidney tubular epithelial cells (HK2) under oxidative stress conditions to investigate the impact of mitochondrial ROS on TFAM (mitochondrial transcription factor A), Lon protease, mitochondrial DNA copy number, mitochondrial respiration, and cytokine release. The experiment involved treating HK2 cells with oxidative stress inducers and measuring changes in TFAM protein levels, mtDNA copy number, and various mitochondrial function parameters. This cellular model was used to mechanistically investigate how mtROS affects mitochondrial DNA maintenance.

Protocol

HK2 cells treated with oxidative stress conditions, with measurements of TFAM protein levels, mtDNA quantification, mitochondrial respiratory function, and inflammatory cytokine production

Expected Outcomes

mtROS would decrease TFAM levels and mtDNA copy number, leading to impaired mitochondrial function and increased cytokine release

Success Criteria

Demonstrable decrease in TFAM and mtDNA with oxidative stress, reversible by mtROS inhibition
