Negative legacy effects of past forest use on plant diversity in semi-natural grasslands on ski slopes

Autor: Yuki A. Yaida, Takuma Nagai, Kazuya Oguro, Koki R. Katsuhara, Kei Uchida, Tanaka Kenta, Atushi Ushimaru

Over the past century, grassland and forest ecosystems globally have been heavily influenced by land use changes driven by diverse socioeconomic activities. Ski resorts are a modern land-use type associated with biodiversity loss in mountain ecosyste

Increase in Tetrahydrobiopterin Release from PC 12 Cells under Hypotonic Culture Conditions is Inhibited by HgCl2

Autor: Akito Tomomura, Kazuya Oguro, Yoshiyuki Hattori, Hiroyuki Hasegawa, Keiichi Tonosaki, Nobuo Nakanishi, Kinji Kurihara

Publikováno v: Pteridines, Vol 16, Iss 1, Pp 1-5 (2005)

Tetrahydrobiopterin (BH4) was released from PC 12 cells to the extracellular fluid. We found that the BH4 outward flow from the cells placed in Hanks medium was increased when NaCl concentration of the medium was decreased. Increase in the BH4 out fl

Proteasome-driven turnover of tryptophan hydroxylase is triggered by phosphorylation in RBL2H3 cells, a serotonin producing mast cell line

Autor: Keiko Sawabe, Nobuo Nakanishi, Kazuya Oguro, Yoshiko Iida, Masayo Kojima, Hiroyuki Hasegawa

Publikováno v: European Journal of Biochemistry. 269:4780-4788

We previously demonstrated in mast cell lines RBL2H3 and FMA3 that tryptophan hydroxylase (TPH) undergoes very fast turnover driven by 26S-proteasomes [Kojima, M., Oguro, K., Sawabe, K., Iida, Y., Ikeda, R., Yamashita, A., Nakanishi, N. & Hasegawa, H

Ability of RBL2H3 Cells to Lower Environmental Tetrahydrobiopterin concentration

Autor: Nobuo Nakanishi, Takahumi Miyazawa, Hiroyuki Hasegawa, Kazumasa Yamamoto, Kazuya Oguro, Yoshie Matsuhashi

Publikováno v: Pteridines, Vol 11, Iss 4, Pp 121-125 (2000)

Tetrahydrobiopterin works as a redox-cofactor inside cells for phenylalanine hydroxylase (1), tyrosine hydroxylase (2), tryptophan hydroxylase (3, 4), and nitric oxide synthetase (5, 6). Other functions oftetrahydrobiopterin so far proposed are modul

Rapid Turnover of Tryptophan Hydroxylase Is Driven by Proteasomes in RBL2H3 Cells, a Serotonin Producing Mast Cell Line

Autor: Yoshiko Iida, Masayo Kojima, Atsushi Yamashita, Kazuya Oguro, Keiko Sawabe, Rie Ikeda, Hiroyuki Hasegawa, Nobuo Nakanishi

Publikováno v: Journal of Biochemistry. 127:121-127

Previously we demonstrated that tryptophan hydroxylase (TPH) undergoes very fast turnover driven by ATP-dependent proteolysis in serotonin producing mast cells [Hasegawa et al. (1995) FEBS Lett. 368, 151-154]. We searched for the major proteases invo

6R-L-erythro-Tetrahydrobiopterin Triggers Serotonin Release with 5HT-loaded RBL2H3 Cells, a Rat Mast Cell Line

Autor: Kazumasa Yamamoto, Hiroyuki Hasegawa, Naomi Nakazawa, Mutsumi Nagano, Nobuo Nakanishi, Kazuya Oguro

Publikováno v: Pteridines, Vol 10, Iss 1, Pp 1-4 (1999)

A new function of tetrahydrobiopterin (BH4) was demonstrated in vitro in which BH4 stimulated serotonergic cells to release serotonin (5HT). RBL2H3 cells were pre-loaded with serotonin at 100 μM for 6 hours. The cells were able to release serotonin

Stimulation of tryptophan hydroxylase production in a serotonin-producing cell line (RBL2H3) by intracellular calcium mobilizing reagents

Autor: Masayo Kojima, Hiroyuki Hasegawa, Yoshiko Iida, Nobuo Nakanishi, Kazuya Oguro

Publikováno v: FEBS Letters. 392:289-292

RBL2H3 cells showed a remarkable increase in their level of tryptophan hydroxylase (up to 25-fold), the rate-limiting enzyme in serotonin biosynthesis, by stimulation with intracellular calcium mobilizers A23187, thapsigargin, and tBuBHQ as well as b
