BACKGROUND Epidermal growth factor (EGF) is critical in cancer process. EGF and EGF receptor (EGFR) interaction plays a pivotal role in cell proliferation, differentiation, and tumorigenesis of epithelial tissues. Variations of the EGF +61G/A (rs4444903) may lead to an alteration in EGF production and/or activity, which can result in individual(More)
Densin-180 is a brain-specific synaptic protein of the o-sialoglycoprotein family. It functions in specific adhesion between presynaptic and postsynaptic membranes at glutamatergic synapses. We have cloned a novel splice variant of densin-180 from a fetal brain cDNA library and termed it LRRC7. It is located on 1p31 and consists of 8 exons. It encodes a(More)
Approximate strategies are crucial in daily human life. The studies on the "difficulty effect" seen in approximate complex arithmetic have long been neglected. Here, we aimed to explore the brain mechanisms related to this difficulty effect in the case of complex addition, using event-related potential-based methods. Following previous path-finding studies,(More)
Global DNA hypomethylation is a most common epigenetic alteration in cancer, but the mechanism remains elusive. Previous studies demonstrate that UHRF1 but not UHRF2 is required for mediating DNA maintenance methylation by DNMT1. Here we report unexpectedly a conserved function for UHRF1 and UHRF2: inhibiting de novo DNA methylation by functioning as E3(More)
