Genomic methylation patterns originate during gametogenesis and are postulated to be involved in important developmental events, including gene regulation, embryogenesis, and genomic imprinting. In previous work, treatment of male rats with 5-azacytidine, a drug that blocks DNA methylation, resulted in abnormal embryo development when germ cells were(More)
Methylation of cytosine residues in mammalian DNA is established during gametogenesis and embryogenesis; it plays an important role in gene regulation and normal embryonic development and has also been implicated in genomic imprinting. In the present study, we evaluated whether paternal administration of 5-azacytidine, a drug that is incorporated into DNA(More)
BACKGROUND Many teratogens induce oxidative stress, altering redox status and redox signaling; this has led to the suggestion that developmental toxicants act by disturbing redox status. The goal of these studies was to determine the consequences of altering glutathione homeostasis during organogenesis on embryo development, total DNA methylation, and(More)
Docetaxel is active in esophagogastric junction (EGJ) adenocarcinoma, and DCF (docetaxel/cisplatin/5-fluorouracil) has shown good results in the neoadjuvant setting. Its high rate of grade 3-4 mucosal toxicity (stomatitis and diarrhea) has limited its widespread adoption. A more recent docetaxel-based triplet, FLOT (5-fluorouracil, oxaliplatin and(More)
