MicroRNAs (miRNAs) are highly expressed in vertebrate neural tissues, but the contribution of specific miRNAs to the development and function of different neuronal populations is still largely unknown. We report that miRNAs are required for terminal differentiation of olfactory precursors in both mouse and zebrafish but are dispensable for proper function(More)
The neurofibromatoses are a diverse group of genetic conditions that share a predisposition to the development of tumors of the nerve sheath. Schwannomatosis is a recently recognized third major form of neurofibromatosis (NF) that causes multiple schwannomas without vestibular tumors diagnostic of NF2. Patients with schwannomatosis represent 2.4 to 5% of(More)
Genetic studies of sup-9, unc-93, and sup-10 strongly suggest that these genes encode components of a multi-subunit protein complex that coordinates muscle contraction in Caenorhabditis elegans. We cloned sup-9 and sup-10 and found that they encode a two-pore K channel and a novel transmembrane protein, respectively. We also found that UNC-93 and SUP-10(More)
I never expected to spend most of my life studying worms. However, when it came time for me to choose an area for my postdoctoral research, I was intrigued both with the problems of neurobiology and with the approaches of genetics. Having heard that a new “genetic organism” with a remarkably simple nervous system was being explored by Sydney Brenner – the(More)
To provide population data on levels of plasma cholesterol, triglyceride, and high- and low-density lipoprotein-cholesterol (HDL-C and LDL-C) in black adults, 627 black adults, aged 20 to 59 years, 206 men and 421 women, were studied in the Cincinnati Lipid Research Clinic's Princeton School Study. Comparisons were made with 2,493 white adults, aged 20 to(More)

The Caenorhabditis elegans locus lin-15 negatively regulates an intercellular signaling process that induces formation of the hermaphrodite vulva. The lin-15 locus controls two separate genetic activities. Mutants that lack both activities have multiple, ectopic pseudo-vulvae resulting from the overproduction of vulval cells, whereas mutants defective in(More)
