The ATP5PO Knockout HeLa Polyclonal Cells are a CRISPR/Cas9-edited polyclonal knockout cell population targeting the ATP5PO gene in HeLa cells. This heterogeneous pool of loss-of-function cells is generated by CRISPR/Cas9-mediated genome editing, providing a robust model for studying ATP5PO function without clonal selection bias. The polyclonal format enables population-level analyses of gene disruption effects, making it suitable for diverse experimental applications.
HeLa cells, an immortalized human cervical adenocarcinoma epithelial cell line, are widely used in biomedical research due to their robust growth and genetic tractability. Derived from cervical adenocarcinoma, they exhibit a transformed phenotype with high aerobic glycolysis (Warburg effect), making them an ideal host for studying cancer metabolism. The ATP5PO Knockout HeLa Polyclonal Cells exploit this background to dissect mitochondrial ATP synthase function in a cancer-relevant context.
ATP5PO encodes the oligomycin sensitivity-conferring protein (OSCP), a subunit of mitochondrial ATP synthase (Complex V) that couples proton transport to ATP synthesis. Disruption of ATP5PO impairs this coupling, reducing mitochondrial ATP production and promoting metabolic shifts toward glycolysis. Upstream regulators include PPARGC1A, NRF1, NRF2, TFAM, and mTOR, which control mitochondrial biogenesis. OSCP interacts with ATP synthase F1 subunits (ATP5A1, ATP5B, ATP5C1) and functions within the electron transport chain alongside Complexes I-IV, cytochrome c, coenzyme Q, and the adenine nucleotide translocator.
In HeLa cells, which rely heavily on glycolysis, ATP5PO knockout exacerbates the Warburg effect and serves as a model for oxidative phosphorylation deficiency. The polyclonal population captures heterogeneous metabolic adaptations, enabling studies of metabolic flexibility and resistance mechanisms. This system is valuable for identifying synthetic lethal interactions and evaluating metabolic drug candidates, as cells become more dependent on alternative energy pathways.
Research applications include cancer metabolism, mitochondrial dysfunction, drug sensitivity/resistance, Warburg effect analysis, and mitochondrial disease research. Key assays: Western blotting for ATP5PO, ATP bioluminescence assay, mitochondrial membrane potential (JC-1/TMRE), Seahorse oxygen consumption, cell viability under metabolic stress, ROS detection, and apoptosis assays.
