The role of Ca²⁺ in synaptic vesicle endocytosis remains uncertain due to the diversity in various preparations where several forms of endocytosis may contribute variably in different conditions. Although recent studies have demonstrated that Ca²⁺ is important for clathrin-mediated endocytosis (CME), the mechanistic role of Ca²⁺ in CME remains to be(More)
Cordycepin (3'-deoxyadenosine) is the main functional component of Cordycepins militaris, a renowned traditional Chinese medicine, which has been shown to possess anti-tumor, anti-inflammatory, anti-diabetic and neuro-protective effects. However, the effect of cordycepin on the central nervous system (CNS) remains unclear. In this study, the effects of(More)
Actin polymerization is important for vesicle fission during clathrin-mediated endocytosis (CME), and it has been proposed that actin polymerization may promote vesicle fission during CME by providing direct mechanical forces. However, there is no direct evidence in support of this hypothesis. In the present study, the role of actin polymerization in(More)
AIMS Cordycepin plays an important role in modulating the function of central nervous system (CNS). However, the modulating mechanism is poorly understood. Excitatory synaptic transmission, the essential process in brain physiology and pathology, is critical in the signal integration activities of the CNS. To further understand the effects of cordycepin on(More)
Isolated toad gastrocnemius muscle is a typical skeletal muscle tissue that is frequently used to study the motor system because it is an important component of the motor system. This study investigates the effects of cordycepin on the skeletal muscle contractile function of isolated toad gastrocnemius muscles by electrical field stimulation. Results showed(More)
Cordycepin has been widely used in oriental countries to maintain health and improve physical performance. Compound nerve action potential (CNAP), which is critical in signal conduction in the peripheral nervous system, is necessary to regulate physical performance, including motor system physiological and pathological processes. Therefore, regulatory(More)
Cordycepin has important neuroprotective effects in hypoxic or ischemic insult. However, the direct electrophysiological evidence of cordycepin's neuroprotection from hypoxic or ischemic insult remains unknown. Hence, in this study, the electrophysiological mechanism by which cordycepin protects against ischemic and hypoxic damages has been studied using an(More)
OBJECTIVE To investigate the expression of cyclin E in rectal carcinoma and its prognostic significance. METHODS Cyclin E expression was examined by Western blotting in tumor tissue samples from 130 potentially resected rectal cancer patients with pathological stages I- III. Blood vessel invasion (BVI) was detected by immunohistochemistry. Multivariate(More)
BACKGROUND Tenuigenin (TEN), a natural product from the Chinese herb Polygala tenuifolia root, has been reported to improve cognitive function and exhibits neuroprotective effects in pharmacological studies of the central nervous system. Synaptic transmission is the essential process of brain physiological functions such as learning and memory formation,(More)
