    COX-1, COX-2, and CD147 appear to be independently regulated in oral squamous cell carcinoma (OSCC), potentially representing 2 therapeutic targets for future investigation. COX-1 expression in OSCC deserves further study because it may be an important determinant of PGE2 secretion from OSCC cells

    Study shows that higher COX-2 and ALOX5 expression in colorectal cancer (CRC) tissues was correlated with poorer prognosis in patients with CRC. Also, MiR-216a-3p was shown to directly bind to there 3'-UTR and inversely regulates their protein levels modulating CRC cell proliferation.

    Data suggest that mutations in MT-CO2 and MT-ND5 can be involved in MIDD (maternally inherited diabetes and deafness); a Tunisian family (mother, daughter, son) with clinical features of MIDD associated with retinopathy exhibit mutations in MT-CO2 (m.8241T>G - p. F219C) and MT-ND5 (m.13276G>A - p. M314V); these two mutations could explain retinopathy in some family members. (MT-ND5 = NADH dehydrogenase subunit 5)

    The sequencing analysis revealed the presence of 17 variants, mostly causing non-synonymous changes in conserved amino acid residues, typically distributed in the MT-CO2 gene of MUTYH-associated polyposis patients (P < 0.0001), who frequently carried the hot spot m.7763G>A variant.

    Results find that COA6 associates with COX2 and is crucial for its maturation and complex IV biogenesis. Also, COA6 interacts with the copper chaperone SCO1 which indicates that COA6 is intrinsically involved in the copper delivery process for COX2.

    COA6 is a mitochondrial complex IV assembly factor critical for biogenesis of mtDNA-encoded COX2.
