Background: Major depressive disorder (MDD) is a common psychological disorder worldwide. However, one-third of patients with MDD are resistant to the present anti-depressant medicine, which regulates monoamine contents in the brain. Thus, another drug target is strongly required. Much evidence strongly suggests that sirtuin1, which is the key factor in regulating the mitochondrial activity, may be implicated in MDD. Read More

Transient receptor potential (TRP) channels, especially canonical TRP channel subfamily members 3 (TRPC3) and 6 (TRPC6), have gained attention as a putative therapeutic target of heart failure. Moreover, TRPC3 and TRPC6 channels are physiologically important for maintaining cellular homeostasis. How TRPC3/C6 channels alter intracellular signaling from adaptation to maladaptation, has been discussed for many years Read More

Delirium is a very common but annoying clinical state that interferes with the treatment of background disease and delays recovery. Delirium is a troublesome condition that exhausts not only the patient but also his/her family and healthcare professionals. Since aging is a risk factor for delirium, how to control delirium is an extremely important issue in an aging society. Phenotype of delirium is so diverse that it is difficult Read More

We present an overview of genetic, metabolomic, proteomic and neurochemical studies done mainly in our laboratories that could improve prediction, mechanistic understanding and possibly extend to diagnostics and treatment of alcoholism and alcohol addiction. Specific polymorphisms in genes encoding for interleukins 2 and 6, catechol-O-methyl transferase (COMT), monaminooxidase B (MAO B) and sev Read More

Background: Melatonin, a neurohormone secreted from the pineal gland, circulates throughout the body and then mediates several physiological functions. The pharmacological effects of melatonin can be mediated through its direct antioxidant activity and receptor-dependent signaling. Objective: This article will mainly review receptor-dependent signaling. Human melatonin receptors include melatonin receptor type 1 ( Read More

Objective: Osteoarthritis is a common disease of the joint cartilage. Since the molecular pathogenesis of osteoarthritis is not clearly understood, early diagnostic markers and effective therapeutic agents have not been developed. Methods and Results: In recent years, there are several studies to elucidate the molecular aspects based on mouse genetics by using a stress-induced mechanical load model. Chondrocyte hypertroph Read More

Autism spectrum disorder (ASD) is a neurodevelopmental disease, and the number of patients has increased rapidly in recent years. The causes of ASD involve both genetic and environmental factors, but the details of causation have not yet been fully elucidated. Many reports have investigated genetic factors related to synapse formation, and alcohol and tobacco have been reported as environmental factors. This review focuse Read More

Arterial atherosclerosis is the main pathological cause of coronary artery disease and peripheral arterial disease. Atherosclerosis is a chronic condition characterized by the presence of cholesterol-rich macrophages in the arterial intima. Accumulation of cholesterol in these macrophages is due to increased oxidation of low-density lipoprotein (LDL) and its uptake via scavenger receptors on the macrophages. Cholesterol ef Read More

IL-19 is a type of anti-inflammatory cytokine. Since the receptor for IL-19 is common to IL-20 and IL-24, it is important to clarify the role of each of the three cytokines. If three different cytokines bind to the same receptor, these three may have been produced to complement the other two. However, perhaps it is unlikely. Recently, the existence of a novel receptor for IL-19 was suggested. The distinction between the roles of Read More

Attention deficit hyperactivity disorder (ADHD) is a psychiatric disorder commonly found in children, which is recognized by hyperactivity and aggressive behavior. It is known that the pathophysiology of ADHD is associated with neurobiological dysfunction. Although psychostimulants are recognized as the therapeutic drugs of choice for ADHD patients, the side effects might be of great concern. Ginkgo biloba is a promisin Read More

Among the various orphan G protein-coupled receptors, apelin receptor (APJ), originally identified in the human genome as an orphan G-protein-coupled receptor, was deorphanised in 1998 with the discovery of its endogenous ligand, apelin. Apelin and APJ mRNA are widely expressed in peripheral tissues and the central nervous system in mammals. In this review, we discuss the characteristics, pharmacology, physiology, Read More

Background: The enhancement of learning and memory through food-derived ingredients is of great interest to healthy individuals as well as those with diseases. Ergothioneine (ERGO) is a hydrophilic antioxidant highly contained in edible golden oyster mushrooms (Pleurotus cornucopiae var. citrinopileatus), and systemically absorbed by its specific transporter, carnitine/organic cation transporter OCTN1/SLC22A4. Objective: T Read More

Background: Mutations in the brain-derived neurotrophic factor (BDNF) gene and its receptor, tyrosine receptor kinase B (TrkB), have been reported to cause severe obesity in rodents. Our previous study demonstrated that the oral administration of 5% Eucommia leaf extract (ELE) or ELE aroma treatment (ELE aroma) produced anti-obesity effects. Objective: In this study, we investigated the effects of ELE on glycolysis Read More

Background: Decreases in female hormones not only affect bone metabolism and decrease bone mass, but also affect the central nervous system, causing brain disorders such as depression and dementia. Administration of estradiol by hormone replacement therapy can improve dementia, while reduced estradiol in ovariectomized (OVX) model rats can reduce both bone density and locomotor activity. The antidepressant flu Read More

Aims: To show that acetate attenuates neuroinflammatory responses in activated microglia. Background: Dietary acetate supplementation alleviates neuroglial activation in a rat model of neuroinflammation induced by intraventricular administration of lipopolysaccharide (LPS). However, the precise mechanism(s) underlying the anti-inflammatory effect of acetate, is not fully understood. Objective: To determine whether a Read More
