Introduction: Although the association between cancer and sarcoidosis or sarcoid reaction is known, sarcoid reaction associated with Merkel cell carcinoma is rare.
Keratinocytes secrete vascular endothelial growth factor (VEGF) and angioregulatory chemokines during cutaneous wound healing. Hepatocyte growth factor (HGF) promotes skin re-epithelialization by increasing VEGF expression in keratinocytes. Here, we investigated the regulatory roles of HGF in the expression of genes encoding angiogenic and angiostatic… (More)
Osteopontin (OPN) is an osteogenic marker protein. Osteoblast functions are affected by inflammatory cytokines and pathological conditions. OPN is highly expressed in bone lesions such as those in rheumatoid arthritis. However, local regulatory effects of OPN on osteoblasts remain ambiguous. Here we examined how OPN influences osteoblast responses to… (More)
