Abstract

Epigallocatechin-3-gallate (EGCG), the major anti-inflammatory compound in green tea, has been shown to suppress osteoclast differentiation. However, the precise molecular mechanisms underlying the inhibitory action of EGCG in osteoclastogenesis and the effect of EGCG on inflammation-mediated bone destruction remain unclear. In this study, we found that EGCG inhibited osteoclast formation induced by osteoclastogenic factors in bone marrow cell-osteoblast cocultures but did not affect the ratio of receptor activator of nuclear factor kappaB (NF-kappaB) ligand (RANKL) to osteoprotegerin induced by osteoclastogenic factors in osteoblasts. We also found that EGCG inhibited osteoclast formation from bone marrow macrophages (BMMs) induced by macrophage colony-stimulating factor plus RANKL in a dose-dependent manner without cytotoxicity. Pretreatment with EGCG significantly inhibited RANKL-induced the gene expression of c-Fos and nuclear factor of activated T-cells (NFATc1), essential transcription factors for osteoclast development. EGCG suppressed RANKL-induced activation of c-Jun N-terminal protein kinase (JNK) pathway, among the three well known mitogen-activated protein kinases and also inhibited RANKL-induced phosphorylation of the NF-kappaB p65 subunit at Ser276 and NF-kappaB transcriptional activity without affecting the degradation of IkappaBalpha and NF-kappaB DNA-binding in BMMs. The inhibitory effect of EGCG on osteoclast formation was somewhat reversed by retroviral c-F…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
