Hedgehog and Fgf signaling pathways regulate the development of tphR-expressing serotonergic raphe neurons in zebrafish embryos (2004)

Teraoka, H., Russell, C., Regan, J., Chandrasekhar, A., Concha, M. L., Yokoyama, R., ...

Serotonin (5HT) plays major roles in the physiological regulation of many behavioral processes, including sleep, feeding, and mood, but the genetic mechanisms by which serotonergic neurons arise...

Population-based genetic alterations in Ewing's tumors from Japanese and European Caucasian patients (2002)

Ozaki, T., Wai, D., Yokoyama, R., Ahrens, S., Diallo, R., ...

Background: The incidence of Ewing’s tumors (ETs) is lower in Asians or African-Americans than in Caucasians. Patients and methods: Japanese ETs were available for analysis of chromosomal...

Role of neuronal nitric oxide in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced dopaminergic neurotoxicity.

Przedborski, S, Jackson-Lewis, V, Yokoyama, R, Shibata, T, Dawson, V L, Dawson, T M

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) causes nigrostriatal dopaminergic pathway damage similar to that observed in Parkinson disease (PD). To study the role of NO radical in...

Convergent evolution of the red- and green-like visual pigment genes in fish, Astyanax fasciatus, and human.

Yokoyama, R, Yokoyama, S

We have isolated and sequenced genes from the blind cave fish, Astyanax fasciatus, that are homologous to the human red and green visual pigment genes. The data strongly suggest that, like human,...

Analysis of the rolC promoter region involved in somatic embryogenesis-related activation in carrot cell cultures.

Fujii, N, Yokoyama, R, Uchimiya, H

In cell cultures of carrot (Daucus carota L.), somatic embryogenesis can be induced by transferring cells from a medium containing 2,4-dichlorophenoxyacetic acid (2,4-D) to one devoid of 2,4-D....

The Arabidopsis ERECTA gene encodes a putative receptor protein kinase with extracellular leucine-rich repeats.

Torii, K U, Mitsukawa, N, Oosumi, T, Matsuura, Y, Yokoyama, R, Whittier, R F, ...

Arabidopsis Landsberg erecta is one of the most popular ecotypes and is used widely for both molecular and genetic studies. It harbors the erecta (er) mutation, which confers a compact inflorescence,...

Internal micronuclear DNA regions which include sequences homologous to macronuclear telomeres are deleted during development in Tetrahymena.

Yokoyama, R, Yao, M C

C4A2 repeats are present in multiple clusters in both the macronucleus and micronucleus of Tetrahymena. Although the macronucleus is generated from the micronucleus after sexual conjugation, the...

Sequence characterization of Tetrahymena macronuclear DNA ends.

Yokoyama, R, Yao, M C

Tetrahymena is a ciliated protozoan which has two nuclei: a micronucleus, which maintains the genetic continuity of the cell, and the macronucleus which is derived from the micronucleus after sexual...

Role of neuronal nitric oxide in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced dopaminergic neurotoxicity.

Osteosarcoma with cytokeratin expression: a clinicopathological study of six cases with an emphasis on differential diagnosis from metastatic cancer

Okada, K, Hasegawa, T, Yokoyama, R, Beppu, Y, Itoi, E

Aims: To clarify the clinicopathological profile of osteosarcomas showing an intensely positive immunoreaction for cytokeratin.

Prognostic relevance of rosette-like features in osteosarcoma

Okada, K, Hasegawa, T, Yokoyama, R, Beppu, Y, Itoi, E

Aims: To clarify the prognostic relevance of rosette-like features and other clinicopathological and immunohistochemical variables in patients with osteosarcoma.

Repetitive speech disorder resulting from infarcts in the paramedian thalami and midbrain.

Abe, K, Yokoyama, R, Yorifuji, S

A repetitive speech disorder resulting from infarcts in the paramedian thalami and the midbrain is reported. Although the speech disorder seemed like stuttering, the compulsive repetitions, constant...
