Depression is one of the most pervasive and debilitating psychiatric diseases, and the molecular mechanisms underlying the pathophysiology of depression have not been elucidated. Cyclin-dependent kinase 5 (Cdk5) has been implicated in synaptic plasticity underlying learning, memory, and neuropsychiatric disorders. However, whether Cdk5 participates in the(More)
Glycogen synthase kinase 3beta (GSK-3beta) is a ubiquitous serine/threonine protein kinase involved in a number of signaling pathways. Previous studies have demonstrated a role for GSK-3beta in the synaptic plasticity underlying dopamine-associated behaviors and diseases. Drug sensitization is produced by repeated exposure to the drug and is thought to(More)
It has been reported that lysosomal proteases play important roles in ischemic and excitotoxic neuronal cell death. We have previously reported that cathepsin B expression increased remarkably after traumatic brain injury (TBI). The present study sought to investigate the effects of a selective cathepsin B inhibitor (CBI)(More)
Acute membrane damage due to traumatic brain injury (TBI) is a critical precipitating event. However, the subsequent effects of the mechanical trauma, including mitochondrial and lysosomal membrane permeability (MOMP and LMP) remain elusive. The main objective of the current study was to assess the role of a putative membrane-resealing agent poloxamer 188(More)
Abnormal baseline brain functional connectivity in attention-deficit/hyperactivity disorder (ADHD) has been revealed in a number of studies by using resting-state functional MRI (rfMRI). The aim of this study was to investigate the spontaneous frontal activities in medication-naïve ADHD boys using the rfMRI derived index, amplitude of low-frequency(More)
Heroin use has seriously threatened public heath in many countries, but the existing therapies continue to have many limitations. Recently, immunotherapy has shown efficacy in some clinical studies, including vaccines against nicotine and cocaine, but no opioid vaccines have been introduced in clinical studies. The development of a novel opioid antigen(More)
As a ubiquitous serine/threonine protein kinase, glycogen synthase kinase 3β (GSK-3β) has been considered to be important in the synaptic plasticity that underlies dopamine-related behaviors and diseases. We recently found that GSK-3β activity in the nucleus accumbens (NAc) core is critically involved in cocaine-induced behavioral sensitization. The present(More)
Hypokalemic periodic paralysis (HypoPP) is an autosomal dominant disorder characterized by periodic attacks of muscle weakness associated with a decrease in the serum potassium level. Several mutations in the skeletal muscle calcium channel α-subunit gene CACNA1S have been documented to be causative for HypoPP, but mutations in other genes have also been(More)
UNLABELLED MicroRNA 370 (miR-370) is located within the DLK1/DIO3 imprinting region on human chromosome 14, which has been identified as a cancer-associated genomic region. However, the role of miR-370 in malignances remains controversial. Here, we report that miR-370 was repressed in human hepatocellular carcinoma (HCC) tissues and hepatoma cell lines.(More)
Acupuncture is a therapeutic technique and part of traditional Chinese medicine (TCM). Acupuncture has clinical efficacy on various autonomic nerve-related disorders, such as cardiovascular diseases, epilepsy, anxiety and nervousness, circadian rhythm disorders, polycystic ovary syndrome (PCOS) and subfertility. An increasing number of studies have(More)
