TXB-001, a newly-developed polymer-conjugated anthracycline: Significantly lower adverse effects in animal models of alopecia and hand-foot syndrome.

Anthracycline anti-cancer drugs have been widely used in the treatment of several cancers; however, their use is limited by adverse effects (AEs). Alopecia is a common AE that is minimally invasive, but adversely affects mental health and reduces quality of life (QoL). Hand-foot syndrome (HFS) is a dose-limiting AE of DOXIL, a liposomal formulation of doxorubicin (DOX).

Hypothetical novel simulations to explain the evolutionary survival of the hypo-reproductive extreme tail in the complex human diversity.

Hierarchical structures which lie hidden between human complex conditions and reproductivity cannot be simple, and trends of each population component does not necessarily pertain to evolutionary theories. As an illustration, the fitness of individuals with heritable extreme conditions can be low across continuing generations in observational data. Autism and schizophrenia are characterized by such evolutionary paradox of survival and hypo-reproductivity in the complex human diversity.

Evaluation of the repeated-dose liver micronucleus assay using 2,4-dinitrotoluene: a report of a collaborative study by CSGMT/JEMS.MMS.

The liver micronucleus assay using young adult rats has the potential to detect liver carcinogens by repeated dosing, and could be expected to be integrated into repeated-dose toxicity studies using a hepatocyte isolation method without the traditional in situ collagenase perfusion. In this study, to assess the performance of the repeated-dose liver micronucleus assay, 2,4-dinitrotoluene (DNT), which is a rodent liver carcinogen, was administered orally to male rats at doses of 50, 100 and 200 mg/kg/day once daily for 14 or 28 consecutive days, and the frequencies of micronucleated hepatocytes (MNHEPs) and micronucleated immature erythrocytes (MNIMEs) were examined. Significant increases in the MNHEPs were observed at 50 mg/kg/day or more in the 14-day treatment, and 50 and 100 mg/kg/day in the 28-day treatment.

Characteristics of TRK-130 (Naltalimide), a novel opioid ligand, as a new therapeutic agent for overactive bladder.

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), TRK-130 showed high selectivity for MORs (Ki for MORs, DORs, and KORs = 0.268, 121, and 8.

Distinct arthropathies of the hands in patients with anti-aminoacyl tRNA synthetase antibodies: usefulness of autoantibody profiles in classifying patients.

Objective: The aim of this study was to characterize arthropathies of the hands associated with antiaminoacyl tRNA synthetase (ARS) autoantibodies.

Methods: Fifty-six patients with anti-ARS antibodies were selected from consecutive patients who visited Keio University Hospital between1983 and 2011, based on their joint symptoms and the availability of hand X-rays. Their clinical characteristics, anti-CCP antibodies, RF, and hand X-ray findings were retrospectively examined.

The multicenter study of a new assay for simultaneous detection of multiple anti-aminoacyl-tRNA synthetases in myositis and interstitial pneumonia.

Objective: Autoantibodies to aminoacyl-tRNA synthetases (ARSs) are useful in the diagnosis of idiopathic inflammatory myopathy (IIM) with interstitial pneumonia (IP). We developed an enzyme-linked immunosorbent assay (ELISA) system using a mixture of recombinant ARS antigens and tested its utility in a multicenter study.

Methods: We prepared six recombinant ARSs: GST-Jo-1, His-PL-12, His-EJ and GST-KS expressed in Escherichia coli, and His-PL-7 and His-OJ expressed in Hi-5 cells.

A genome-wide association study identified AFF1 as a susceptibility locus for systemic lupus eyrthematosus in Japanese.

Systemic lupus erythematosus (SLE) is an autoimmune disease that causes multiple organ damage. Although recent genome-wide association studies (GWAS) have contributed to discovery of SLE susceptibility genes, few studies has been performed in Asian populations. Here, we report a GWAS for SLE examining 891 SLE cases and 3,384 controls and multi-stage replication studies examining 1,387 SLE cases and 28,564 controls in Japanese subjects.

Toxicological effect of emodin in mouse testicular gene expression profile.

Emodin (1,3,8-trihydroxy-6-methyl-anthraquinone) is a herbal medicine extracted from the rhizomes of Rheum palmatum, and is known as an inhibitor of casein kinase II (CK2). The CK2α' knockout mice are known to be male-infertile; however, there have been no reports on the toxicity of emodin in male reproductive organs/tissues. To evaluate the toxicological effects of emodin on differential gene expression profiles of the testis as compared with acrylamide, mice were orally administered emodin and acrylamide for 5 days at a dose of 1000 and 50 mg kg(-1) per day, respectively, and euthanized 24 h after the final administration.

The association of a nonsynonymous single-nucleotide polymorphism in TNFAIP3 with systemic lupus erythematosus and rheumatoid arthritis in the Japanese population.

Objective: Genome-wide association (GWA) studies in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) in Caucasian populations have independently identified risk variants in and near the tumor necrosis factor alpha (TNFalpha)-induced protein 3 gene (TNFAIP3), which is crucial for the regulation of TNF-mediated signaling and Toll-like receptor signaling. The aim of this study was to assess the role of TNFAIP3 in the development of SLE and RA in Japanese subjects.

Methods: We selected 2 single-nucleotide polymorphisms (SNPs) from previous GWA studies.

Clinical associations with autoantibody reactivities to individual components of U1 small nuclear ribonucleoprotein.

The reactivities to individual U1 small nuclear ribonucleoprotein (snRNP) components and their relationship to clinical features in patients with anti-U1 snRNP antibodies were examined. We evaluated 114 patients with connective tissue disease whose sera were positive for anti-U1 snRNP antibodies, but negative for anti-Sm antibodies. Antibodies to the U1 snRNP polypeptides 70K, A, and C were detected using subunit-specific enzyme-linked immunosorbent assays and antibodies to U1 small nuclear RNA (snRNA) were identified by an immunoprecipitation assay using deproteinized HeLa cell extracts.
