We identified a p53 target gene, phosphate-activated mitochondrial glutaminase (GLS2), a key enzyme in conversion of glutamine to glutamate, and thereby a regulator of glutathione (GSH) synthesis and energy production. GLS2 expression is induced in response to DNA damage or oxidative stress in a p53-dependent manner, and p53 associates with the GLS2(More)
The neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP), a member of the glucagon/vasoactive intestinal peptide (VIP) superfamily, stimulates cyclic AMP accumulation initiating a variety of biological processes such as: neurotropic actions, immune and pituitary function, learning and memory, catecholamine biosynthesis and regulation of(More)
CONTEXT Pheochromocytoma is a catecholamine-producing tumor that originates from adrenal chromaffin cells and is capable of secreting various hormones, including ACTH. CASE DESCRIPTION A 56-year-old female presented with Cushingoid appearance and diabetic ketoacidosis. Endocrinological examinations demonstrated ectopic ACTH production with(More)
To understand the molecular pathogenesis of human esophageal cancer, we performed a comparative genomic hybridization (CGH) analysis using 10 esophageal squamous cell carcinomas. Frequent gains of 1q, 3q, 7p, 7q, 8q, 11q, and 20q and losses of 3p, 4p, 4q, 5q, 9p, 11p, 11q, 13q, 18q, 21q, and Y were observed. Among these regions, 21q has not yet been(More)
For about 6 years after the marketing of oral formulations of fosfomycin calcium (FOM-Ca) in December, 1980, we collected the data on 35,481 cases and analyzed it regarding safety. Primary side-effects consisted mainly in gastrointestinal disturbances, damage to skin and adnexa, liver and bile duct disorders. Specifically, diarrhea, nausea, abdominal pain,(More)
We investigated genetic alterations of the p53 gene in two patients with multiple primary oesophageal squamous cell carcinomas (ESCs). We found that each primary tumour could be distinguished by mutation of p53. Moreover, mutations detected in the p53 gene in metastatic lymph nodes were the same as those detected in at least one of the primary tumours. Our(More)
Glucocorticoids have strong regulatory actions on the immune system and act as potent therapeutic compounds for autoimmune and inflammatory diseases. We previously reported that the long noncoding RNA growth arrest-specific 5 (Gas5), which accumulates inside the cells in response to cellular starvation/growth arrest, functions as a potent repressor of the(More)
A postmarketing surveillance of cefminox sodium (Meicelin, CMNX) for intravenous injection was conducted for about 4 years from August 1987 through June 1991, and 13,431 patients were followed up to evaluate the safety of the drug. The incidence of side-effects was 1.76%. By organ, the most frequently observed were hepatic and of the bile duct system(More)
