Polyclonal Anti-5-Hydroxymethyluridine

Cat. No: GPA040H       

5-Hydroxymethyl-2’-deoxyuridine (HmdU) is formed from thymidine during the oxidation of DNA by ionizing radiation or reactive oxygen species (ROS)vthat are formed from inflammatory response.  This causes genetic mutations, altered gene expression and chromosomal instability that has generally been implicated with aging, cancers and autoimmune diseases.

 Systemic oxidative stress levels, as evidenced by DNA damage products in the blood and urine, appear to be associated with a risk of various cancers, including that of the breast, lung and colorectal cancers.  Cigarette smoke contains numerous chemical carcinogens and other compounds that generate reactive oxygen species that can damage DNA directly or indirectly via inflammatory processes.  HmdU is one of the major oxidized DNA bases that is significantly elevated in the white blood cells of women diagnosed with beast cancer, which may be a result of diminished DNA repair.  Individuals with BRCA1 and BRCA2 mutations may be at increased risk for cancer due to deficiencies in the repair of DNA lesions caused by ROS.  Additionally, antibody titers recognizing HmdU have also been found to be significantly elevated in women with breast, color and rectal cancers.  Therefore, oxidative DNA damage is therefore an attractive marker of disease risk as it takes into account not only the exposure to and production of oxidants, but also the cells’ DNA repair ability.

A goat antiserum to 5-hydroxymethyuridine (5-HmUrd) is currentlywpe5.gif (29641 bytes) available. This antiserum has been shown to be immunoreactive with 5-HmUrd-modified bovine serum albumin (BSA) by ELISA. This antibody should be a valuable tool for scientists working to understand the relevance of 5-HmdUrd as a marker for oxidative stress and it's relationship to the pathogenesis of various diseases.
