BACKGROUND: Low back pain is a common problem, mainly caused by intervertebral disc degeneration (IDD). An important pathophysiological characteristic of IDD is the loss of homeostatic balance of the extracellular matrix metabolism. Interleukin-1β (IL-1β) is one of the inflammatory mediators stimulating the degradation of extracellular matrix in the nucleus pulposus (NP) and contributing to IDD pathogenesis. Icariin, which is isolated from Epimedium brevicornum, acts as an anti-inflammatory drug...

Icariin (ICA) is a pharmacologically active flavonoid glycoside that shows promise in the treatment and prevention of osteoporosis (OP). However, the mechanisms underlying the anti-osteoporotic effects of ICA remain largely unclear. The present study used quantitative polymerase chain reaction, western blot and immunohistochemical analysis to examine the effects of ICA on several key targets in the Notch signaling pathway in bone tissue in ovariectomized rats. It was observed that ICA has a pronounced beneficial effect on OP rats and inhibits the expression of peroxisome proliferator-activated receptor γ (PPARγ), CCAAT/enhancer binding protein α (C/EBPα) and fatty acid-binding protein 4 (FABP4) mRNA...

Osteoporosis is a serious public health concern worldwide. Herba epimedii has been used for centuries and even thousands of years to treat osteoporotic conditions. Icariin, a flavonol glycoside, is one of the major active ingredients. In this study, we have shown that icariin protected against glucocorticoid-induced osteoporotic changes in SaoS-2 cells and mice. We have also shown that dexamethasone (a glucocorticoid) suppressed and icariin induced DEC1, a structurally distinct helix-loop-helix protein. DEC1 overexpression promoted whereas DEC1 knockdown decreased osteogenic activity...

BACKGROUND AND PURPOSE: Icariin is a potent stimulator of osteogenic differentiation; however, the mechanism underlying its osteogenic effect remains unclear. The osteogenic effect of icariin is related to the upstream glucocorticoid-induced leucine zipper (GILZ) signaling pathway, and antagonism with dexamethasone-induced osteoblast inhibition was noted. METHODS: MC3T3-E1 cells were cultured in induced medium treated with icariin with or without dexamethasone. After short interfering RNA (siRNA) were used to silence GILZ expression, the degree of mineralization, proliferation, and GILZ expression as well as the levels of osteogenic (OPG, RANKL, ALP, OC and RUNX2) markers were tested...
