Myostatin is involved in an inhibitor of muscular growth and differentiation. Myoblasts derived from double-muscled Japanese shorthorn cattle (DM myoblasts) with absence of functional myostatin had higher abilities to proliferate and differentiate than myoblasts derived from normal-muscled cattle (NM myoblasts). In DM myoblasts, mRNA expressions of fetal(More)
After the treatment of human neuroblastoma SH-SY5Y cells with retinoic acid for 24 h, the expression of c-Ret receptor tyrosine kinase was greatly elevated. Treatment of SH-SY5Y cells with glial cell line-derived neurotrophic factor under serum-free conditions after incubation of cells with retinoic acid resulted in the phosphorylation of c-Ret receptor(More)
In an earlier screening, we identified several genes for kinases that might control the extension of neurites. One of these genes encoded a leukocyte tyrosine kinase (LTK), which is a receptor tyrosine kinase whose ligands remain to be identified. To examine the possible role of this LTK in neurite outgrowth, we constructed a chimeric receptor, in which the(More)
Transfection microarrays (TMA) are important emerging tools for the study of genetic events in living cells in a high-throughput fashion and with significant material economy. However, the difficulty to transfect various relevant cell types on-chip hinders the use of TMAs. Herein we present the realization of a transfection microarray applicable to PC12(More)
There are two independent serotonin (5-HT) systems of organization: one in the central nervous system and the other in the periphery. 5-HT affects feeding behavior and obesity in the central nervous system. On the other hand, peripheral 5-HT also may play an important role in obesity, as it has been reported that 5-HT regulates glucose and lipid metabolism.(More)
AMP-activated protein kinase (AMPK) regulates metabolism in skeletal muscle, and myostatin (MSTN) negatively regulates skeletal muscle development and growth. In the present study, AMPK activation and the relationship between AMPK and MSTN during myogenic differentiation were investigated in cultures derived from bovine skeletal muscle. Myoblasts capable of(More)
Recent studies show that myostatin mRNA expression is found in some regions of the brain. However, the functional significance of this is currently unknown. We therefore investigated myostatin expression and function in the brain. In this study, we used immunohistochemistry, in situ hybridization, and RT-PCR analysis to reveal that myostatin is expressed in(More)
Cell migration plays a major role in a variety of normal biological processes, and a detailed understanding of the associated mechanisms should lead to advances in the medical sciences in areas such as cancer therapy. Previously, we developed a simple chip, based on transfected-cell microarray (TCM) technology, for the identification of genes related to(More)
Nerve growth factor (NGF)-induced neurite maturation in PC12D cells involves neuritogenesis and neurite outgrowth. Actions of compounds affecting the neurite maturation are sometimes invisible behind the individually variable events in nature even in the clonal population. In this study, we designed a time-lapse imaging system to determine the timing of(More)
Bacillus subtilis is the main component in the fermentation of soybeans. To investigate the genetics of the soybean-fermenting B. subtilis strains and its relationship with the productivity of extracellular poly-γ-glutamic acid (γPGA), we sequenced the whole genome of eight B. subtilis stains isolated from non-salted fermented soybean foods in Southeast(More)
