Icariin, the main active flavonoid glucoside isolated from Herba epimedii (HEF), is an anabolic agent in bone that has been reported to prevent bone loss in ovariectomized rats and postmenopausal women. However, the molecular mechanism for this anabolic action of Icariin remain largely unknown. Here, we found that Icariin could promote MC3T3-E1 osteoblastic(More)
The spatial and temporal distribution of transcripts for the tumor suppressor gene Rb, transcription factor E2F1, cdc2 kinase, cyclins D1, D2, B1 and B2 during neurogenesis of the spinal cord was determined by in situ hybridization. The Rb and E2F1 transcripts were detectable in proliferating and differentiating cells. By contrast, cdc2, cyclins D1, B1 and(More)
The delta-opioid receptors in mouse neuroblastoma x rat glioma NG108-15 cells were characterized by receptor binding and cAMP assays. Saturation binding assays using [3H][D-Pen5]enkephalin (DPDPE) or [3H][D-Ser2, Leu5, Thr6]enkephalin (DSLET) gave similar binding capacities (Bmax). Competition binding assays showed that DPDPE and DSLET have similar affinity(More)
The cannabinoid receptors expressed in the mouse neuroblastoma X rat glioma NG108-15 cell and the rat pituitary tumor GH4C1 cell were determined by polymerase chain reaction, dideoxysequencing and pharmacologically. The CB1 but not the CB2 or CB1A cannabinoid receptor was found in both cell lines. The cDNA identified in GH4C1 cells corresponds to the rat(More)
