The identification of new molecular components of the DNA damage signaling cascade opens novel avenues to enhance the efficacy of chemotherapeutic drugs. High-mobility group protein 1 (HMGB1) is a DNA damage sensor responsive to the incorporation of nonnatural nucleosides into DNA; several nuclear and cytosolic proteins are functionally integrated with(More)
We explored the role of a chromatin-associated nuclear protein high mobility group protein B1 (HMGB1) in apoptotic response to widely used anticancer drugs. A murine fibroblast model system generated from Hmgb1(+)(/)(+) and Hmgb1(-/-) mice was used to assess the role of HMGB1 protein in cellular response to anticancer nucleoside analogs and precursors,(More)
Warfarin is the most widely used oral anticoagulant in the world for patients with venous thrombosis, pulmonary embolism, chronic atrial fibrillation, and prosthetic heart valves. Approximately 30 genes contribute to therapeutic effects of warfarin, and genetic polymorphisms in these genes may modulate its anticoagulant activity. In contrast to monogenic(More)
Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is a multifunctional protein that acts at the intersection of energy metabolism and stress response in tumor cells. To elucidate the role of GAPDH in chemotherapy-induced stress, we analyzed its activity, protein level, intracellular distribution, and intranuclear mobility in human carcinoma cells A549 and(More)
OBJECTIVES Metoclopramide is associated with variable efficacy and side effects when used in the treatment of gastroparesis. AIM To determine associations of clinical and pharmacogenetic parameters with response and side effects to metoclopramide in patients with upper gastrointestinal symptoms suggestive of gastroparesis. METHODS Gastroparetic patients(More)
DNA mismatch repair enzymes (for example, MSH2) maintain genomic integrity, and their deficiency predisposes to several human cancers and to drug resistance. We found that leukemia cells from a substantial proportion of children (∼11%) with newly diagnosed acute lymphoblastic leukemia have low or undetectable MSH2 protein levels, despite abundant wild-type(More)
Domperidone is a useful alternative to metoclopramide for treatment of gastroparesis due to better tolerability. Effectiveness and side-effects from domperidone may be influenced by patient-related factors including polymorphisms in genes encoding drug-metabolizing enzymes, drug transporters, and domperidone targets. The aim of this study was to determine(More)
AIMS Chemotherapy-associated cognitive impairment often follows cancer chemotherapy. We explored chemotherapy-induced DNA damage in the brain cells of mice treated with 5-fluorouracil (5FU), an antineoplastic agent, to correlate the extent of DNA damage to behavioral functioning in an autoshaping-operant mouse model of chemotherapy-induced learning and(More)
BACKGROUND Renewed interest in total ankle arthroplasty (TAA) has developed globally as a result of recent literature supporting new-generation implants as a viable alternative to arthrodesis. The literature also demonstrates a learning curve among surgeons adopting TAA. The purpose of this study is to better define this learning curve for surgeons using(More)
Carbinol [4,4'-(hydroxymethylene)dibenzonitrile] is the main phase 1 metabolite of letrozole, a nonsteroidal aromatase inhibitor used for endocrine therapy in postmenopausal breast cancer. We elucidated the contribution of UDP-glucuronosyltransferase (UGT) isoforms on the glucuronidation of carbinol. Identification of UGT isoforms was performed using a(More)
