Dynorphin increases extracellular levels of excitatory amino acids in the brain through a non-opioid mechanism.
Administration of dynorphin A-(1-17) (Dyn 1-17), through a microdialysis probe stereotaxically placed into rat hippocampus, caused marked increases in the extracellular levels of glutamate and aspartate. The degree and duration of elevation of these excitatory amino acids (EAA) induced by Dyn 1-17 were dose dependent but were not modified by the centrally active opioid receptor antagonist nalme...
متن کاملCytotoxicity of ICD-85 NPs on Human Cervical Carcinoma HeLa Cells through Caspase-8 Mediated Pathway
The biological application of nanoparticles (NPs) is a rapidly developing area of nanotechnology that raises new possibilities in the treatment of human cancers. The cytotoxicity was evaluated by MTT and LDH assays. The apoptotic effect of free ICD-85 and ICD-85 NPs on HeLa cells was assessed using caspase-8 colorimetric assay. The MTT assay showed that ICD-85 NPs could enhance the in-vitro cyt...

متن کاملDynorphin A elicits an increase in intracellular calcium in cultured neurons via a non-opioid, non-NMDA mechanism.
The opioid peptide dynorphin A is known to elicit a number of pathological effects that may result from neuronal excitotoxicity. An up-regulation of this peptide has also been causally related to the dysesthesia associated with inflammation and nerve injury. These effects of dynorphin A are not mediated through opioid receptor activation but can be effectively blocked by pretreatment with N-met...
متن کاملEffects and Mechanism of Baicalin on Apoptosis of Cervical Cancer HeLa Cells In-vitro
The objective of this study was to observe the apoptosis-inducing effect and mechanism of baicalin on human cervical cancer HeLa cells. The inhibitory effect of baicalin on the growth of HeLa cells was measured by MTT assay, and cell proliferation and migration was analyzed by cell scratch assay. Morphological changes of apoptotic cells were viewed by the light microscope and electron microscop...
