Involvement of Islet-2 in the Slit signaling for axonal branching and defasciculation of the sensory neurons in embryonic zebrafish (2004)

Yeo, Sang-Yeob, Miyashita, Toshio, Fricke, Cornelia, Little, Melissa H., Yamada, Toshiya, Kuwada, John Y., ...

In Drosophila melanogaster, Slit acts as a repulsive cue for the growth cones of the commissural axons which express a receptor for Slit, Roundabout (Robo), thus preventing the commissural axons from...

Molecular Cloning and Analysis of the cDNA for an Auxin-Regulated Calmodulin Gene (1995)

Okamoto, Hitoshi, Tanaka, Yoshiyuki, Sakai, Shingo

An auxin-regulated calmodulin cDNA (arCaM) were isolated by differential screening from a mung bean (Vigna radiata) cDNA library. The expression of the arCaM transcript in the etiolated mung bean...

Outgrowth by fin motor axons in wildtype and a finless mutant of the Japanese medaka fish (1991)

Okamoto, Hitoshi, Kuwada, John Y.

The outgrowth of motor axons to the developing pectoral fin of the Japanese medaka fish (Oryzias latipes) was investigated both in wildtype embryos and in the pectoral finless (pl) mutants in which...

Alteration of pectoral fin nerves following ablation of fin buds and by ectopic fin buds in the Japanese medaka fish (1991)

Okamoto, Hitoshi, Kuwada, John Y.

The role of the pectoral fin bud for outgrowth by fin axons was assessed by ablation of pectoral fin buds and by transplantation of fin buds to ectopic sites in the embryos of the Japanese medaka...

Heat Shock Gene Activation by Mutant Actin Is Independent of Myofibril Degeneration in Drosophila Muscle (1991)

Sakai, Yutaka, Okamoto, Hitoshi, Mogami, Kaname, Matsuo, Hiroki, Hotta, Yoshiki

Artificially mutagenized Drosophila Act88F actin genes with triple and double mutations were expressed in the indirect flight muscles of transgenic flies. The triple mutant actin, GD246T...

Actin with Tumor-Related Mutation Is Antimorphic in Drosophila Muscle: Two Distinct Modes of Myofibrillar Disruption by Antimorphic Actins (1990)

Sakai, Yutaka, Okamoto, Hitoshi, Mogami, Kaname, Yamada, Takuma, Hotta, Yoshiki

A mutant β-actin with an amino acid substitution from Gly-245 to Asp has been shown to be related to tumorigenic transformation of a human fibroblast cell line (Leavitt, J. et al (1987)Mol. Cell...

Elimination of metabolic cooperation by glycyrrhetinic acid, an anti-tumor promoter, in cultured Chinese hamster cells (1986)

Tsuda, Hirohisa, Okamoto, Hitoshi

The effect of glycyrrhetinic acid (GA) on the metabolic cooperation between 6-thioguanine-resistant (6TGR) and sensitive (6TGs) Chinese hamster V79 H3 cells, was investigated. Because GA has been...

Molecular characterization of mutant actin genes which induce heat-shock proteins in Drosophila flight muscles

Okamoto, Hitoshi, Hiromi, Yasushi, Ishikawa, Etsuko, Yamada, Takuma, Isoda, Kazuyoshi, Maekawa, Hideaki, ...

Heat-shock proteins (hsps) are constitutively induced by the mutant actins in the Drosophila indirect flight muscles (IFM). We compared primary structures of the mutant actin genes (KM75 and HH5)...
