Cardiac fibroblasts (CFs) regulate myocardial remodeling by proliferating, differentiating, and secreting extracellular matrix proteins. Prolonged activation of CFs leads to cardiac fibrosis and reduced myocardial contractile function. Resveratrol (RES) exhibits a number of cardioprotective properties; however, the possibility that this compound affects CF(More)
BACKGROUND Bupivacaine is an amide type local anesthetic which is widely used for epidural anesthesia and nerve blockade in patients. However, local administration of bupivacaine could cause neuron injury showing transient neurologic symptoms. alpha-Lipoic acid (LA) was shown to protect nerve cells from substance-induced injury. We hypothesized that LA(More)
Protein kinase CK2 (CK2), a ubiquitous serine/threonine protein kinase for hundreds of endogenous substrates, serves as an attractive anticancer target. One of its most potent inhibitors, CX-4945, has entered a phase I clinical trial. Herein we present an integrated workflow combining shape-based virtual screening for the identification of novel CK2(More)
Lithium, a drug used for the treatment of bipolar disorder, has been shown to affect different aspects of neuronal development such as neuritogenesis, neurogenesis and survival. The underlying mechanism responsible for lithium's influence on neuronal development, however, still remains to be elucidated. In the present study, we demonstrate that lithium(More)
BACKGROUND AND PURPOSE HSPA12B is a newly discovered member of the Hsp70 family proteins. This study investigated the effects of HSPA12B on focal cerebral ischemia/reperfusion (I/R) injury in mice. METHODS Transgenic mice overexpressing human HSPA12B (Tg) and wild-type littermates (WT) were subjected to 60 min of middle cerebral artery occlusion to induce(More)
Cardiac fibroblast (CF) proliferation and differentiation into hypersecretory myofibroblasts can lead to excessive extracellular matrix (ECM) production and cardiac fibrosis. In turn, the ECM produced can potentially activate CFs via distinct feedback mechanisms. To assess how specific ECM components influence CF activation, isolated CFs were plated on(More)
BACKGROUND Neurite outgrowth is an important aspect of neuronal plasticity and regeneration after neuronal injury. Alpha-lipoic acid (LA) has been used as a therapeutic approach for a variety of neural disorders. We recently reported that LA prevents local anesthetics-induced neurite loss. In this study, we hypothesized that LA administration promotes(More)
Oxidative stress plays an important role in cardiac diseases, which has been well demonstrated, whereas the role of reductive stress has been poorly investigated. We and others have shown previously that heat shock protein 27 (Hsp27) plays a role as an antioxidant. To investigate whether overexpression of Hsp27 could lead to reductive stress and result in(More)
The Friedewald formula (FF) is useful for calculating serum low-density lipoprotein cholesterol (LDL-C) values, but has a remarkable deviation and limitation especially in hypertriglyceridemia. We modify the formula which is now more suitable for LDL-C calculation. 2180 cases were classified into three groups according to their TG concentrations (A: < 200(More)
Current surgical management of volume overload-induced heart failure (HF) leads to variable recovery of left ventricular (LV) function despite a return of LV geometry. The mechanisms that prevent restoration of function are unknown but may be related to the timing of intervention and the degree of LV contractile impairment. This study determined whether(More)
