Anti-double stranded DNA (anti-dsDNA) antibodies are highly associated with SLE. They are a very specific marker for the disease, with some studies quoting nearly 100%. [8] Data on sensitivity ranges from 25 to 85%. Anti-dsDNA antibody levels, known as titres, correlate with disease activity in SLE; high levels indicate more active lupus.
Mitochondrial DNA is the small circular chromosome found inside mitochondria. These organelles, found in all eukaryotic cells, are the powerhouse of the cell. [1] The mitochondria, and thus mitochondrial DNA, are passed exclusively from mother to offspring through the egg cell.
Anti-double stranded DNA (Anti-dsDNA) antibodies are a group of anti-nuclear antibodies (ANA) the target antigen of which is double stranded DNA. Blood tests such as enzyme-linked immunosorbent assay (ELISA) and immunofluorescence are routinely performed to detect anti-dsDNA antibodies in diagnostic laboratories.
Mitochondrial matrix has a pH of about 7.8, which is higher than the pH of the intermembrane space of the mitochondria, which is around 7.0–7.4. [5] Mitochondrial DNA was discovered by Nash and Margit in 1963. One to many double stranded mainly circular DNA is present in mitochondrial matrix. Mitochondrial DNA is 1% of total DNA of a cell.
Anti-mitochondrial antibodies (AMA) are autoantibodies, consisting of immunoglobulins formed against mitochondria, [1] primarily the mitochondria in cells of the liver.. The presence of AMA in the blood or serum of a person may be indicative of the presence of, or the potential to develop, the autoimmune disease primary biliary cholangitis (PBC; previously known as primary biliary cirrhosis).
Mitochondrial diseases range in severity from asymptomatic to fatal, and are most commonly due to inherited rather than acquired mutations of mitochondrial DNA. A given mitochondrial mutation can cause various diseases depending on the severity of the problem in the mitochondria and the tissue the affected mitochondria are in.
In 1999 it was reported that telomeres, which cap the end of chromosomes, terminate in a lariat-like structure termed a T-loop (Telomere-loop). [11] This is a loop of both strands of the chromosome which are joined to an earlier point in the double-stranded DNA by the 3' strand end invading the strand pair to form a D-loop.
ATM (ATM) is also a protein kinase that is recruited and activated by DNA double-strand breaks. DNA double-strand damages activate the Fanconi anemia core complex (FANCA/B/C/E/F/G/L/M). [25] The FA core complex monoubiquitinates the downstream targets FANCD2 and FANCI. [26] ATM activates (phosphorylates) CHEK2 and FANCD2 [27] CHEK2 ...
