A sufficient supply of NADPH is a critical factor in l-lysine production by Corynebacterium glutamicum. Endogenous NAD-dependent glyceraldehyde 3-phosphate dehydrogenase (GAPDH) of C. glutamicum was replaced with nonphosphorylating NADP-dependent glyceraldehyde 3-phosphate dehydrogenase (GapN) of Streptococcus mutans, which catalyzes the reaction of(More)
OBJECTIVE To clarify the potential of TRK-380 as a drug for overactive bladder in humans by evaluating the agonistic activities for human β-adrenergic receptors (β-ARs) and the relaxing effects on isolated detrusor strips. METHODS The agonistic activities for human β-ARs were evaluated in SK-N-MC cells (for human β(3)-ARs) and Chinese hamster ovary cells(More)
For genotyping of feline major histocompatibility complex (FLA) class II DRB, the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method using group-specific primers was tried. Sixty-six DRB genes were classified into 8 groups according to differences in the first 5' amino acid sequences. The group-specific primers were(More)
The P19CL6 cell line is a useful model to study cardiac differentiation in vitro. However, large variations were noticed in the differentiation rates among previous reports as well as our individual experiments. To overcome the unstable differentiation, we established P19CL6-A1, a new clonal derivative of P19CL6 that could differentiate into cardiomyocytes(More)
Neurofibromatosis type 1 (NF1) is the most common genetic condition caused by NF1 gene alteration. A 1.5 Mb submicroscopic deletion encompassing the entire NF1 gene, is known to be responsible for approximately 5% of NF1 cases. Patients with NF1 deletion, compared to those with NF1 mutation tend to exhibit more severe phenotypes. To know the possible(More)
The PST-01 protease is secreted by the organic solvent-tolerant microorganism Pseudomonas aeruginosa PST-01 and is stable in the presence of various organic solvents. Therefore, the PST-01 strain and the PST-01 protease are very useful for fermentation and reactions in the presence of organic solvents, respectively. The organic solvent-stable PST-01(More)
Various procedure-related adverse events related to colonoscopic treatment have been reported. Previous studies on the complications of colonoscopic treatment have focused primarily on perforation or bleeding. Coagulation syndrome (CS), which is synonymous with transmural burn syndrome following endoscopic treatment, is another typical adverse event. CS is(More)
We characterized TRK-130 (N-[(5R,6R,14S)-17-(cyclopropylmethyl)-4,5-epoxy-3,14-dihydroxymorphinan-6-yl]phthalimide; naltalimide), an opioid ligand, to clarify the therapeutic potential for overactive bladder (OAB). In radioligand-binding assays with cells expressing human µ-opioid receptors (MORs), δ-opioid receptors (DORs), or κ-opioid receptors (KORs),(More)
