Article Synopsis
  • Mesenchymal stromal cells (MSCs) differentiate into cartilage and bone under the control of key signaling pathways, with protein kinases playing a significant role in this process.
  • Mast4 acts as a mediator in TGF-β and Wnt signaling, influencing MSC differentiation: TGF-β1 suppresses Mast4 to enhance chondrogenesis, while Wnt signaling promotes osteogenesis by stabilizing Mast4.
  • Mice lacking Mast4 exhibit excessive cartilage production but also show signs of osteoporosis, indicating that Mast4 is crucial in dictating whether MSCs develop into cartilage or bone.

Foxf2 represses bone formation via Wnt2b/β-catenin signaling.

Exp Mol Med

June 2022

Department of Orthopaedics, Graduate School, Tokyo Medical and Dental University, 1-5-45 Yushima, Bunkyo-Ku, Tokyo, 113-8519, Japan.

Differentiation of mesenchymal stem cells (MSCs) into osteoblasts is a critical process for proper skeletal development and acquisition/maintenance of bone mass. However, since this regulatory mechanism has not yet been fully elucidated, the treatment of severe osteoporosis and fractures is a challenge. Here, through a comprehensive analysis of gene expression during the differentiation of MSCs into osteoblasts, we show that the forkhead transcription factor Foxf2 is a crucial regulator of this process.

Studies have proposed that individuals with autism spectrum disorder (ASD) can be divided into several subtypes depending on their sensory features. However, consideration of social communication features is also crucial for configuring ASD subtypes, because social and sensory features are tightly interrelated. In this study, we asked Japanese individuals with ASD to answer the Short Sensory Profile (SSP) and the Social Responsiveness Scale, Second Edition (SRS-2), which measure sensory and social aspects, respectively.

Gene Therapy for Fibrodysplasia Ossificans Progressiva: Feasibility and Obstacles.

Hum Gene Ther

August 2022

Department of Human Genetics, Amsterdam University Medical Centers, Vrije Universiteit Amsterdam, Amsterdam Rare Bone Disease Center, Amsterdam Bone Center, Amsterdam Movement Sciences, Amsterdam, The Netherlands.

Fibrodysplasia ossificans progressiva (FOP) is a rare and devastating genetic disease, in which soft connective tissue is converted into heterotopic bone through an endochondral ossification process. Patients succumb early as they gradually become trapped in a second skeleton of heterotopic bone. Although the underlying genetic defect is long known, the inherent complexity of the disease has hindered the discovery of effective preventions and treatments.

Background: The most common gene responsible for autosomal recessive retinitis pigmentosa (RP) is EYS. The manner of decay of genetically defective EYS gene transcripts varies depending on the type of mutation using our cellular model, which consists of induced photoreceptor-directed fibroblasts from EYS-RP patients (EYS-RP cells). However, disease-specific profiles have not been clarified in EYS-RP cells.

Individuals with autism spectrum disorder (ASD) have atypical sensory processing, particularly when sensory stimuli are delivered from different modalities with a temporal lag of subseconds. Previous studies have suggested that individuals with ASD require a longer temporal lag to judge temporal orders of successive audiovisual stimuli than neurotypical individuals; however, it remains unclear whether a lower temporal resolution in the visuotactile domain is associated with an individual's autistic traits. In addition, a previous study demonstrated that visuotactile temporal resolution degraded when the participants saw a hand image on a display.

Extracellular signal-regulated kinase 5 (Erk5) belongs to the mitogen-activated protein kinase (MAPK) family. Previously, we demonstrated that Erk5 directly phosphorylates Smad-specific E3 ubiquitin protein ligase 2 (Smurf2) at Thr249 (Smurf2Thr249) to activate its E3 ubiquitin ligase activity. Although we have clarified the importance of Erk5 in embryonic mesenchymal stem cells (MSCs) on skeletogenesis, its role in adult bone marrow (BM)-MSCs on bone homeostasis remains unknown.

Purpose: This systematic review identified and synthesized published research articles, written in Japanese, on the clinical effectiveness of a broad range of nonpharmacological interventions for school-age children who stutter.

Method: A systematic review of Japanese literature published between January 1, 1980, and July 7, 2020, reporting interventions for school-age children who stutter, was carried out through a search of two databases (CiNii Article database and Japan Medical Abstract Society database) using the key words "stuttering" and "school-age" or "child" or "primary school students" or "children" or "school child" in Japanese. To be included in the review, the articles must report studies where data were subjectively reported by clinicians, where school-age participants were treated for developmental stuttering, where participants received interventions conducted by clinicians, and where quantitative outcomes (pre- and/or posttreatment) were measured; and they must be published in Japanese.

Previous psychophysical studies reported a positive aftereffect in tactile temporal order judgments, which can be explained by the Bayesian estimation model ('Bayesian calibration'). We investigated the relationship between Bayesian calibration and autistic traits in participants with typical development (TD) and autism spectrum disorder (ASD). Bayesian calibration was weakened in TD participants with high autistic traits, consistent with the 'hypo-priors' hypothesis for autistic perceptions.

Basic locomotor muscle synergies used in land walking are finely tuned during underwater walking.

Sci Rep

September 2021

Department of Life Sciences, Graduate School of Arts and Sciences, The University of Tokyo, 3-8-1 Komaba, Meguro, Tokyo, 153-8902, Japan.

Article Synopsis
  • Underwater walking is a common exercise in hydrotherapy, and understanding how muscles are controlled during this activity is vital for training optimization.
  • The study explores how buoyancy and drag force in water influence walking by examining muscle synergies, which are groups of muscles that work together, rather than just individual muscle actions.
  • Findings indicate that while the same muscle synergies are utilized for both underwater and land walking, the activation patterns and combinations of these muscles are adjusted to suit the unique conditions of walking in water.

Multiple patterns of infant rolling in limb coordination and ground contact pressure.

Exp Brain Res

September 2021

Graduate School of Education, The University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo, 113-0033, Japan.

Infants acquire the ability to roll over from the supine to the prone position, which requires body coordination of multiple degrees of freedom under dynamic interactions with the ground. Although previous studies on infant rolling observed kinematic characteristics, little is known about the kinetic characteristics of body segments in contact with the surface. We measured the ground contact pressure under the arms, legs, head, and proximal body segments using a pressure mat and their displacements using a three-dimensional motion capture system.
