The M2-PK Test is a non-invasive screening method for the early detection of colorectal cancers and polyps which are known to be the precursors of colorectal cancer. The M2-PK Test which is used for stool analysis is available either as fully quantitative ELISA Test or as a rapid test that can be performed by any general practitioner without the need of a laboratory or any additional equipment.
Mitochondrial biogenesis is the process by which cells increase mitochondrial numbers. [ 1 ] [ 2 ] It was first described by John Holloszy in the 1960s, when it was discovered that physical endurance training induced higher mitochondrial content levels, leading to greater glucose uptake by muscles.

The American College of Gastroenterology has recommended the abandoning of gFOBT testing as a colorectal cancer screening tool, in favor of the fecal immunochemical test (FIT). [3] The newer and recommended tests look for globin, DNA, or other blood factors including transferrin, while conventional stool guaiac tests look for heme.
M2-PK, as measured in feces, is a potential tumor marker for colorectal cancer.When measured in feces with a cutoff value of 4 U/ml, its sensitivity has been estimated to be 85% (with a 95% confidence interval of 65 to 96%) for colon cancer and 56% (confidence interval 41–74%) for rectal cancer.

The human mitochondrial genome is the entirety of hereditary information contained in human mitochondria. Mitochondria are small structures in cells that generate energy for the cell to use, and are hence referred to as the "powerhouses" of the cell. Mitochondrial DNA (mtDNA) is not transmitted through nuclear DNA (nDNA).
Formation of ROS as a mitochondrial waste product will eventually lead to cytotoxicity and cell death. Because of their role in metabolism, mitochondria are very susceptible to ROS damage. Damaged mitochondria cause a depletion in ATP and a release of cytochrome c, which leads to activation of caspases and onset of apoptosis. Mitochondrial ...
Mitochondrial respirometry measures the consumption of oxygen by the mitochondria without involving an entire living animal and is the main tool to study mitochondrial function. [13] Three different types of samples may be subjected to such respirometric studies: isolated mitochondria (from cell cultures, animals or plants); permeabilized cells ...
Midzone division is linked to mitochondrial biogenesis, which occurs when the cell is proliferating and requires an increased number of mitochondria. In contrast, peripheral division is associated with the removal of damaged mitochondrial units from the network, with these mitochondria being targeted for autophagy or mitophagy, leading to their ...
