BACKGROUND Matricellular proteins, including periostin, are important for tissue regeneration. METHODS AND FINDINGS Presently we investigated the function of periostin in cutaneous wound healing by using periostin-deficient ⁻/⁻ mice. Periostin mRNA was expressed in both the epidermis and hair follicles, and periostin protein was located at the basement(More)
Acute myocardial infarction (AMI) is a common and lethal heart disease, and the recruitment of fibroblastic cells to the infarct region is essential for the cardiac healing process. Although stiffness of the extracellular matrix in the infarct myocardium is associated with cardiac healing, the molecular mechanism of cardiac healing is not fully understood.(More)
The intergenic region-internal ribosome entry site (IGR-IRES) of dicistroviruses binds to 40S ribosomal subunits in the absence of eukaryotic initiation factors (eIFs). Although the conserved loop sequences in dicistroviral IGR-IRES elements are protected from chemical modifications in the presence of the 40S subunit, molecular components in the 40S(More)
BACKGROUND Matricellular proteins, including periostin, modulate cell-matrix interactions and cell functions by acting outside of cells. METHODS AND FINDINGS In this study, however, we reported that periostin physically associates with the Notch1 precursor at its EGF repeats in the inside of cells. Moreover, by using the periodontal ligament of molar from(More)
Neurodegeneration correlates with Alzheimer's disease (AD) symptoms, but the molecular identities of pathogenic amyloid β-protein (Aβ) oligomers and their targets, leading to neurodegeneration, remain unclear. Amylospheroids (ASPD) are AD patient-derived 10- to 15-nm spherical Aβ oligomers that cause selective degeneration of mature neurons. Here, we show(More)
Induced pluripotent stem cells (iPSCs) hold promise as a potential treatment for Duchenne muscular dystrophy (DMD). To determine the impact of the donor's age on reprogramming, we generated iPSCs from muscle-derived fibroblasts (MuFs) of mdx mice aged 6 weeks, 6 months, and 14 months. MuFs from 14-month-old mdx mice showed lower proliferative activity and(More)
There has been a great deal of work recently in the fields of teleoperation and telerobotics [5]. In these man-machine systems, a robot arm or a land vehicle are commanded to move in real-time by a human operator who is viewing the progress of the operation. The decisions on the task of moving the arm or vehicle to the desired position are made by the(More)
