The meiotic recombination checkpoint is a signalling pathway that blocks meiotic progression when the repair of DNA breaks formed during recombination is delayed. In comparison to the signalling pathway itself, however, the molecular targets of the checkpoint that control meiotic progression are not well understood in metazoans. In Drosophila, activation of the meiotic checkpoint is known to pr...
The 5-methylationcytosine (5-MC) DNA content of murine embryonic fibroblasts arrested in G1 by four growth conditions (Gc, Gn, Gd, and Gs) were hypermethylated relative to rapidly growing (RG) fibroblasts. Normal human keratinocytes (NHK) arrested in G1 by suspension were hypermethylated relative to RG cultures. Four RG cultures of epidermoid carcinoma cells (ECC) were hypomethylated relative t...

Malectin was first discovered as a novel endoplasmic reticulum (ER)-resident lectin from Xenopus laevis that exhibits structural similarity to bacterial glycosylhydrolases. Like other intracellular lectins involved in glycoprotein quality control, malectin is highly conserved in animals. Here results from in vitro membrane-based binding assays and frontal affinity chromatography confirm that hu...
Selenite (SeL) or selenomethionine (SeM) are the most common selenium (Se) compounds taken as dietary antioxidants to reduce oxidative stress. Because the public may frequently supplement Se compounds at high doses, the possible pro-oxidant effect of Se becomes a concern. SeL and SeM have entirely different pharmacokinetic effects based on dose-related cytotoxicity. Our laboratory has shown pre...
