TFAM knockdown functional analysis

Exploratory Score: 0.850 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: mtDNA levels, mitochondrial function, cytokine release

Description

Gene silencing experiment using siRNA or shRNA to knockdown TFAM expression in HK2 cells to directly test the role of TFAM in mitochondrial function and cytokine release. This loss-of-function study aimed to determine whether TFAM deficiency alone could recapitulate the mitochondrial dysfunction and inflammatory responses observed with mtROS treatment. The experiment included assessment of mtDNA levels, mitochondrial respiratory capacity, and inflammatory cytokine production following TFAM silencing, with or without Mito-Tempo treatment.

Protocol

TFAM knockdown using siRNA/shRNA in HK2 cells, followed by assessment of mtDNA copy number, mitochondrial respiratory function, and cytokine production, with and without Mito-Tempo treatment

Expected Outcomes

TFAM knockdown would impair mitochondrial function and increase cytokine release, and would prevent Mito-Tempo from rescuing these defects

Success Criteria

TFAM silencing recapitulates mtROS-induced mitochondrial dysfunction and abolishes Mito-Tempo rescue effects
