Non-inferiority in the cumulative castration rate of the 3-month formulation of degarelix compared with the 3-month formulation of goserelin was evaluated in subjects with prostate cancer. A phase III, open-label, parallel-arm study was conducted. An initial dose of 240 mg of degarelix or 3.6 mg of goserelin was subcutaneously administered; after day 28, a maintenance dose of 480 mg of degarelix or 10.8 mg of goserelin was administered once every 84 days. Non-inferiority in castration rate and safety of degarelix to goserelin were evaluated...

Krabbe disease, one of the autosomal-recessive lysosomal storage disorders (LSDs), is caused by a deficiency of galactocerebrosidase (GALC) activity, resulting in the intracellular accumulation of psychosine, which is cytotoxic for neuronal cells. Genetically pathogenic mutations result in conformational changes in GALC and disrupt the lysosmal trafficking of cargos, which subsequently accumulate in the endoplasmic reticulum (ER). Recently, ER stress together with the activation of the unfolded protein response (UPR) has been suggested to play a key role in the pathogenesis of LSDs...

We previously reported that brain-derived neurotrophic factor (BDNF)/neurotrophic receptor tyrosine kinase 2 (NTRK2/TRKB) signaling contributes to induction of malignant phenotype of gallbladder cancer (GBC). Recently, pan-TRK inhibitors have been evaluated and their dramatic clinical activity is being shown for a variety of cancer types harboring an NTRK rearrangement in phase I trials. ONO-7579 is an oral pan-TRK inhibitor currently under investigation in phase I/II clinical trial for TRK-rearranged solid tumors...

There is concern that vitamin D deficiency is prevalent among children in Japan as well as worldwide. We conducted a nationwide epidemiologic survey of symptomatic vitamin D deficiency to observe its incidence rate among Japanese children. A questionnaire inquiring the number of new patients with vitamin D deficiency rickets and/or hypocalcemia for 3 years was sent to 855 randomly selected hospitals with a pediatrics department in Japan. In this survey, we found that 250 children were diagnosed with symptomatic vitamin D deficiency...

Isosamidin is a pharmacologically active compound extracted from Peucedanum japonicum which is used as a health food in East Asia. Our preliminary animal data suggested that isosamidin may have sufficient potency to treat patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia or overactive bladder. However, the efficacy of isosamidin in humans is unknown. Here, we examined whether isosamidin inhibits agonist-stimulated contractions in isolated human bladder and prostate tissue strips in vitro...

Acetobacter pasteurianus is characterized as a fermenting bacterium of kurozu, which is a common traditional Japanese black vinegar. Recently, we separated acid-resistant and low Toll-like receptor 4 (TLR4)-stimulatory lipopolysaccharides (LPS) from A. pasteurianus. We also showed that their lipid A parts possessed a novel sugar backbone that is responsible for the low TLR4-stimulatory and acid-resistant properties of the LPS. Outer membrane vesicles (OMVs) are nano-sized spherical structures secreted from many gram-negative bacteria...

Foxp3(+) regulatory T (Treg) cells, which suppress immune responses, are highly proliferative in vivo. However, it remains unclear how the active replication of Treg cells is maintained in vivo. Here, we show that branched-chain amino acids (BCAAs), including isoleucine, are required for maintenance of the proliferative state of Treg cells via the amino acid transporter Slc3a2-dependent metabolic reprogramming. Mice fed BCAA-reduced diets showed decreased numbers of Foxp3(+) Treg cells with defective in vivo proliferative capacity...

Endometriosis can affect any portion of the gastrointestinal tract. A preoperative definitive diagnosis of intestinal endometriosis is difficult, because there is no characteristic endoscopic finding and the endoscopic biopsies usually sample insufficient endometrial tissue for pathologic diagnosis. To our knowledge, the magnifying endoscopic features of intestinal mucosal endometriosis have not been well documented. In this study, we report a case of intestinal endometriosis diagnosed preoperatively by magnifying image-enhanced colonoscopy and target biopsy...
