Striatum is an important brain area whose function is related to motor, emotion and motivation. Interestingly, biological and physiological circadian rhythms have been found in the striatum extensively, suggesting molecular clock machinery works efficiently therein. However, the striatal expression profiles of clock genes have not been characterized(More)
Despite prolongation of the QTc interval in humans during cerebral ischemia, little is known about the mechanisms that underlie these actions. Cerebral ischemic model was established by middle cerebral artery occlusion (MCAO) for 24 h. In rat ventricular myocytes, the effect of cerebral ischemia on action potential duration (APD) and underlying(More)
Circadian disruptions may result in sleep problems, oxidative stress and an altered inflammatory response. These symptoms may contribute to PD pathogenesis, despite a lack of direct experimental evidence supporting this relationship. Clock genes are essential to drive and maintain circadian rhythm. To elucidate the possible role of circadian disruptions in(More)
The aims of this study were to determine (i) whether striatal neuropeptides (dynorphin, enkephalin 1, substance P, cholecystokinin) and dopamine receptors 1 and 2 (D1r and D2r) are regulated by the molecular clock; and (ii) when their oscillations start after birth. Twenty-four-hour mRNA oscillations of these genes were evaluated in the mouse striatum at(More)
Lumican is a dermatan sulfate proteoglycan highly expressed in connective tissue and has the ability to regulate collagen fibril assembly. Previous studies have shown that lumican is involved in wound healing, but the precise effects of lumican on reepithelialization and wound contraction, the two pivotal aspects of skin wound healing, have not been(More)
Cathepsin K (CTSK) is a member of the papain-like cysteine protease family. Mutations in the CTSK gene cause a rare autosomal recessive bone disorder called pycnodysostosis (OMIM 265800). In order to follow the advances in the research about CTSK and pycnodysostosis, we performed a literature retrospective study of 159 pycnodysostosis patients reported(More)
