The role of adenosine A1 and A3 receptors in mediating cardioprotection has been studied predominantly in rabbits, yet the pharmacological characteristics of rabbit adenosine A1 and A3 receptor subtypes are unknown. Thus, the rabbit adenosine A3 receptor was cloned and expressed, and its pharmacology was compared with that of cloned adenosine A1 receptors.(More)
Pro-opiomelanocortin (POMC) is expressed in the nucleus tractus solitarii (NTS) of the brainstem, where nitric oxide (NO) plays an important role in cardiovascular regulation. The POMC-derived neuropeptides and their receptors are important regulators of energy homeostasis and cardiovascular functions in the central nervous system. In this study, we(More)
BACKGROUND Pro-opiomelanocortin (POMC) is the precursor of several neuropeptides, such as corticotropin, melanocyte-stimulating hormone and the endogenous opioid (β-endorphin). Our previous studies have indicated that POMC gene delivery inhibited the progression and metastasis of B16-F10 melanoma via the α- melanocyte-stimulating hormone/melanortin-1(More)
Neurogenic inflammation frequently causes acute plasma leakage in airways and life-threatening pulmonary edema. However, limited strategies are available to alleviate neurogenic inflammation. Proopiomelanocortin (POMC) is the precursor of anti-inflammatory melanocortins, which have been proposed of therapeutic potential for various inflammatory diseases.(More)
Malignant melanoma is one of the leading causes of cancer mortality worldwide, underlining the need for effective novel therapies. In this study, the therapeutic efficacy and mechanism of systemic pro-opiomelanocortin (POMC) therapy were evaluated in mice bearing established melanoma. Injection of adenovirus encoding POMC (Ad-POMC) led to hepatic POMC(More)
Angiogenesis, the process of neovascularization, plays an important role in physiological and pathological conditions. ST104P is a soluble polysulfated-cyclo-tetrachromotropylene compound with anti-viral and anti-thrombotic activities. However, the functions of ST104P in angiogenesis have never been explored. In this study, we investigated the effects of(More)
BACKGROUND Gene therapy of proopiomelanocortin, the precursor of α-melanocyte-stimulating hormone (α-MSH), suppresses the neovascularization in tumors. However, the roles of α-MSH in angiogenesis remain unclear. METHODS The influence of α-MSH on angiogenesis was evaluated by ex vivo rat aorta and in vivo, including transgenic zebrafish and chicken(More)
