Hypoxia-inducible factor 1 (HIF-1) is regulated by the oxygen-dependent hydroxylation of proline residues by prolyl hydroxylases (PHDs). We recently developed a novel PHD inhibitor, TM6008, that suppresses the activity of PHDs, inducing continuous HIF-1α activation. In this study, we investigated how TM6008 affects cell survival after hypoxic conditions(More)
OBJECTIVE Inositol hexakisphosphate kinase 2 (InsP6K2), an enzyme that converts inositol hexakisphosphate (InsP6) to diphosphoinositol pentakisphosphate (InsP7), induces cell death. InsP6K2 is abundant in the central nervous system, especially anterior horn cells of spinal cord. To identify the role of InsP6K2 in amyotrophic lateral sclerosis (ALS), we(More)
BACKGROUND Various postural deformities appear during progression of Parkinson's disease (PD), but the underlying pathophysiology of these deformities is not well understood. The angle abnormalities seen in individual patients may not be due to distinct causes, but rather they may have occurred in an interrelated manner to maintain a balanced posture. (More)
We report a 44-year-old female with striatonigral degeneration (SND) who showed wearing-off oscillations after 4 months of levodopa treatment. The patient presented with asymmetric left-side dominant rigidity, and levodopa was effective at first. However, she began to show wearing-off oscillations of motor symptoms, which gradually worsened thereafter.(More)
TAR DNA-binding protein 43 (TDP-43) has been identified as a major component of ubiquitin-positive inclusions in the brains and spinal cords of patients with frontotemporal lobar degeneration with ubiquitinated inclusions (FTLD-U) or amyotrophic lateral sclerosis (ALS). The phosphorylated C-terminal fragment of TDP-43 forms aggregates in the neuronal(More)
