Many ion channel genes have been associated with human genetic pain disorders. Here we report two large Chinese families with autosomal-dominant episodic pain. We performed a genome-wide linkage scan with microsatellite markers after excluding mutations in three known genes (SCN9A, SCN10A, and TRPA1) that cause similar pain syndrome to our findings, and we(More)
PURPOSE To identify the disease-causing gene in a Chinese family with autosomal dominant congenital cataract. METHODS Clinical and ophthalmologic examinations were performed on all members of a Chinese family with congenital cataract. Nine genes associated with congenital cataract were screened using direct DNA sequencing. Mutations were confirmed using(More)
Temperature-sensitive TRP channels are important for responses to pain and inflammation, to both of which tissue acidosis is a major contributing factor. However, except for TRPV1, acid-sensing by other ThermoTRP channels remains mysterious. We show here that unique among TRPV1-3 channels, TRPV3 is directly activated by protons from cytoplasmic side. This(More)
A cardiomyocyte differentiation in vitro system from zebrafish embryos remains to be established. Here, we have determined pluripotency window of zebrafish embryos by analyzing their gene-expression patterns of pluripotency factors together with markers of three germ layers, and have found that zebrafish undergoes a very narrow period of pluripotency(More)
