TRAF2, but not TRAF6, regulates breast cancer induced osteoclastogenesis and osteolysis.

Tumour necrosis factor receptor associated factors (TRAFs) play a key role in signal transduction in mammalian cells. Several members of the TRAF family have been identified but only TRAF2 and TRAF6 are implicated in the regulation of osteoclastogenesis. Here we studied the role of TRAF2 and TRAF6 in breast cancer induced bone cell activity and osteolysis. We observed that TRAF2, but not TRAF6, is highly expressed in the human MDA-MB-231 (MDA-231) bone-seeking breast cancer ce...

IκB Kinase β (IKKβ), a key component of NFκB signaling, plays an important role in bone disease and cancer. Genetic and pharmacological inhibition of IKKβ/NFκB signaling increase bone mass and protect against ovariectomy- and inflammation-induced bone loss. Here, we describe a previously unknown role of the IKKβ/FoxO3a axis in bone metastasis associated with breast cancer. We observed that IKKβ expression is prevalent in invasive breast ...
