A method to assess DNA damage using quantitative polymerase chain reaction (QPCR) with an internal control with or without modified QPCR primers is disclosed. The method further included quantitation of QPCR products using a chemiluminescent, colorimetric or fluorescent assay and a real-time PCR. The chemiluminescent, colorimetric or fluorescent assay is carried out with modified PCR primers and the real-time PCR is carried out with PCR primers with or without modification. A method to select a suitable PCR replication cycle number is disclosed. This is to avoid polymerization of PCR products after addition of the internal control. A method to analyze DNA damage and mutagenicity induced by chemicals in DNA damage repair-deficient and proficient fibroblast cells with endogenous expression of oxidative stress-inducing proteins, e.g., prostaglandin H2 synthase form 2 (PGHS-2, also called as COX-2), was disclosed.

This invention discloses diagnosis of risk of chemotherapy-induced cardiotoxicity by measurement of increased expression of soluble epoxide hydrolase in vitro and in vivo in cells, tissues or animals including measurement of increased levels of soluble epoxide hydrolase metabolites, e.g., 14,15-DHET and 11,12-DHET, in biological fluids. This invention also includes diagnosis of risk of chemotherapy-induced cardiotoxicity by measuring increased levels of oxidative stress in cells, tissues or animals including measurement of increased levels of oxidative stress biomarkers, e.g., 8-isoprostane, in biological fluids. Fatty acid and protein biomarkers to diagnose the risk of chemotherapy-induced cardiotoxicity are detected using various detection methods including mass spectrometry and immunoassay such as ELISA, Western blot analysis or label-free microwell and nanowell technologies. This invention discloses targeted medical intervention for a subject who is at risk or with chemotherapy-induced cardiotoxicity by treating with soluble epoxide hydrolase inhibitor(s) with or without antioxidants to prevent or ameliorate the chemotherapy-induced cardiotoxicity.

摘要:
A method of assessing arachidonic acid (AA) metabolites-dependent hypertension by measuring glucuronidated dihydroxyeicosatrienoic acids (DHETs) and DHET metabolites in a biological sample which contains the epitopes unique to DHET (using any methods including GC/MS, LC/MS or ELISA). An example of the glucuronidated DHET metabolite is DHET-alcohols such as omega or omega-1 oxidated DHET and DHET esterified glycerol. The method further includes determining the amount of glucuronidated molecules containing a DHET-specific epitope which is immunoreactive with antibodies produced against DHETs.
