Emodin, as a mitochondrial uncoupler, induces strong decreases in adenosine triphosphate (ATP) levels and proliferation of B16F10 cells, owing to their poor glycolytic reserve.

Many types of cancer cells show a characteristic increase in glycolysis, which is called the "Warburg effect." By screening plant extracts, we identified one that decreases cellular adenosine triphosphate (ATP) levels and suppresses proliferation of malignant melanoma B16F10 cells, but not of noncancerous MEF cells. We showed that its active ingredient is emodin, which showed strong antiproliferative effects on B16F10 cells both in vitro and in vivo.

Prediction of changes in functional ability of inpatients with schizophrenia using logarithmic and linear regression modelling.

Characteristic Clinical Features of Werner Syndrome with a Novel Compound Heterozygous WRN Mutation c.1720+1G>A Plus c.3139-1G>C.

Werner syndrome (WS) is an autosomal recessive progeroid disorder caused by mutations in the WRN gene (WRN). Most Japanese WS patients are born from a consanguineous marriage with homozygous WRN mutations. We herein report a rare WS patient born from non-consanguineous parents with compound heterozygous WRN mutations with a novel heterogeneous c.

Biallelic Mutations in Newly Identified Japanese Werner Syndrome Patients.

Werner syndrome (WS) is a rare autosomal recessive disorder characterized by systemic accelerated aging. It is caused by pathogenic variants of the gene that encodes a nuclear helicase. In this report, we describe 4 newly identified WS cases among those referred to the Japanese Werner Consortium, Chiba University, Japan.

Association of age and time of disease with HIV-associated neurocognitive disorders: a Japanese nationwide multicenter study.

There is no detailed information on the association between age, time of disease, and HIV-associated neurocognitive disorders (HAND). In this prospective study involving 17 medical facilities across Japan, we recruited HIV-infected patients to complete a 14-test neuropsychological battery that assess eight neurocognitive domains. HAND were diagnosed by the Frascati criteria.

WRN Mutation Update: Mutation Spectrum, Patient Registries, and Translational Prospects.

Werner syndrome (WS) is a rare autosomal recessive disorder characterized by a constellation of adult onset phenotypes consistent with an acceleration of intrinsic biological aging. It is caused by pathogenic variants in the WRN gene, which encodes a multifunctional nuclear protein with exonuclease and helicase activities. WRN protein is thought to be involved in optimization of various aspects of DNA metabolism, including DNA repair, recombination, replication, and transcription.

Impact of dementia on behavioral independence and disturbance.

Development of the central and peripheral nervous systems in the lamprey.

Vertebrate brains are highly organized structures that show remarkable diversity throughout the animal groups. Among the vertebrates, the agnathan animals, which diverged from the gnathostomes early in the evolution of the vertebrates, occupy a key phylogenetic position in order to clarify the origin and evolution of the brain. We found that the lamprey brain has the basic molecular mechanisms necessary to form brain compartments.

Development of the lamprey central nervous system, with reference to vertebrate evolution.

Vertebrate brains are highly organized structures that show remarkable diversity throughout animal groups. The agnathans, which diverged from the gnathostomes early in the evolution of the vertebrates, occupy a key phylogenetic position from which to clarify the origin and evolution of the brain. We studied the developing lamprey brain and compared its developmental plan with that of the gnathostomes, in order to reconstruct the evolutionary processes of the vertebrate brain.
