Effects of Lobeglitazone, a New Thiazolidinedione, on Osteoblastogenesis and Bone Mineral Density in Mice.

Background: Bone strength is impaired in patients with type 2 diabetes mellitus despite an increase in bone mineral density (BMD). Thiazolidinedione (TZD), a peroxisome proliferator activated receptor γ agonist, promotes adipogenesis, and suppresses osteoblastogenesis. Therefore, its use is associated with an increased risk of fracture.

Wnt/β-catenin signaling is a key downstream mediator of MET signaling in glioblastoma stem cells.

Background: Glioblastoma (GBM) is the most lethal and common type of primary brain tumor. Recent evidence suggests that a subpopulation of GBM cells (glioblastoma stem cells [GSCs]) is critical for tumor progression, invasion, and therapeutic resistance. We and others have demonstrated that MET, a receptor tyrosine kinase, positively regulates the stemness phenotype and radioresistance of GSCs.

Effects of amniotic membrane suspension in human corneal wound healing in vitro.

Purpose: To investigate the biochemical mechanism of amniotic membrane (AM) suspension on corneal wound healing, particularly on epithelial proliferation and migration.

Methods: Human corneal epithelial cells (HCECs) were cultured in media with different concentrations of AM suspension (5% and 30%), Dulbecco's Modified Eagle Medium: Nutrient Mixture F-12 (negative control), and serum containing Dulbecco's Modified Eagle Medium: Nutrient Mixture F-12 (positive control). In an effort to evaluate the migratory potential of AM, migration assays were conducted via the manual scraping of HCECs and immunocytochemical staining of cell adhesion molecules (E-cadherin).
