Guidelines for the use and interpretation of assays for monitoring autophagy in higher eukaryotes (2008)

Spanel-Borowski, Katharina, Smith, Mark A., Simone, Cristiano, Simonsen, Anne, Simon, Hans-Uwe, ...

Research in autophagy continues to accelerate, and as a result many new scientists are entering the field. Accordingly, it is important to establish a standard set of criteria for monitoring...

Autophagy is not a Main Contributor to the Degradation of Phospholipids in Tobacco Cells Cultured under Sucrose Starvation Conditions (2006)

Inoue, Yuko, Moriyasu, Yuji

Net degradation of cellular components occurs in plant cells cultured under starvation conditions, and autophagy contributes to the degradation of intracellular proteins. In this study, we...

Net degradation of cellular components occurs in plant cells cultured under starvation conditions, and autophagy contributes to the degradation of intracellular proteins. In this study, we...

AtATG genes, homologs of yeast autophagy genes, are involved in constitutive autophagy in Arabidopsis root tip cells (2006)

Inoue, Yuko, Suzuki, Takao, Hattori, Masaki, Yoshimoto, Kohki, Ohsumi, Yoshinori, Moriyasu, Yuji

In Arabidopsis root tips cultured in medium containing sufficient nutrients and the membrane-permeable protease inhibitor E-64d, parts of the cytoplasm accumulated in the vacuoles of the cells from...

AtATG Genes, Homologs of Yeast Autophagy Genes, are Involved in Constitutive Autophagy in Arabidopsis Root Tip Cells (2006)

Inoue, Yuko, Suzuki, Takao, Hattori, Masaki, Yoshimoto, Kohki, Ohsumi, Yoshinori, Moriyasu, Yuji

Contribution of the Plasma Membrane and Central Vacuole in the Formation of Autolysosomes in Cultured Tobacco Cells (2004)

Yano, Kanako, Matsui, Sumiko, Tsuchiya, Tomohiro, Maeshima, Masayoshi, Kutsuna, Natsumaro, Hasezawa, Seiichiro, ...

Autolysosomes accumulate in tobacco cells cultured under sucrose starvation conditions in the presence of a cysteine protease inhibitor. We characterized these plant autolysosomes using fluorescent...

3-Methyladenine Inhibits Autophagy in Tobacco Culture Cells under Sucrose Starvation Conditions (2004)

Takatsuka, Chihiro, Inoue, Yuko, Matsuoka, Ken, Moriyasu, Yuji

Tobacco (Nicotiana tabacum) culture cells perform autophagy and degrade cellular proteins in response to sucrose starvation. When protein degradation is blocked by the cysteine protease inhibitor...

Alpha Tonoplast Intrinsic Protein is Specifically Associated with Vacuole Membrane Involved in an Autophagic Process (2003)

Moriyasu, Yuji, Hattori, Masaki, Jauh, Guang-Yuh, Rogers, John C.

Autophagy in plant cells is induced by nutrient starvation. Initially, double membrane-bound organelles, termed autophagosomes, enclose a portion of cytoplasm, and then fuse with a vacuole or...

Isolation of the Red-light-absorbing Form of Phytochrome from Light-grown Pea Shoots (1981)

Shimazaki, Yukio, Moriyasu, Yuji, Pratt, Lee H., Furuya, Masaki

Phytochrome was extracted from both light-grown and dark-grown shoots of Pisum and partially purified by brushite chromatography and ammonium sulfate fractionation. About 160–270 ng of phytochrome...

Degradation of Proteins Artificially Introduced into Vacuoles of Chara australis1

Moriyasu, Yuji, Tazawa, Masashi

When an exogenous protein, bovine serum albumin, was introduced into the vacuole of a Chara australis internodal cell, it was degraded with time. This degradation proceeded only in the vacuole as far...

Partial Purification and Characterization of Aminopeptidase II from Chara australis

Moriyasu, Yuji, Miyoshi, Yasuhiro

Aminopeptidase II, one of the two major aminopeptidases in the giant alga Chara australis, was partially purified. Its molecular weight was estimated to be about 80,000 by gel permeation...

Vacuolar/Extravacuolar Distribution of Aminopeptidases in Giant Alga Chara australis and Partial Purification of One Such Enzyme 1

Moriyasu, Yuji, Sakano, Katsuhiro, Tazawa, Masashi

The presence of two major aminopeptidases (aminopeptidases I and II) in the giant alga Chara australis was shown using polyacrylamide gel electrophoresis. Partially purified aminopeptidase I had a...
