epigallocatechin gallate/sarcoma

Current treatment of osteosarcoma is associated with poor prognosis, especially due to the increased risk of developing other cancers with chemotherapy. Therefore, new, safe and effective treatment strategies are needed. We investigated the effect of a unique mixture of nutrients containing lysine,

The highly aggressive pediatric sarcomas are characterized by high levels of matrix metalloproteinase (MMP)-2 and MMP-9, which play crucial roles in tumor invasion and metastasis by degradation of the extracellular membrane leading to cancer cell spread to distal organs. We examined the effects of

The highly aggressive adult sarcomas are characterized by high levels of matrix metalloproteinase (MMP)-2 and -9, which play crucial roles in tumor invasion and metastasis by degradation of the extracellular membrane leading to cancer cell spread to distal organs. We examined the effect of

Membrane-type 1 matrix metalloproteinase (MT1-MMP), which hydrolyzes type I collagen and activates MMP-2, are deeply involved in angiogenesis as well as in tumor cell invasion and metastasis. We previously screened a number of natural and synthetic compounds to obtain a specific inhibitor of MT1-MMP

The chemopreventive effect of polyphenols from green tea [e.g. (-)-epigallocatechin gallate (EGCG) and (-)-epigallocatechin (EGC)] against cancer has been demonstrated in several studies. The aim of this investigation was to prove whether these compounds modulate the activity of antineoplastic

Recent evidence suggests that inflammatory cytokines and growth factors contribute to arsenite (As)-induced human carcinogenesis. We investigated the expression of inflammatory cytokine mRNAs during the transformation process induced by chronic As exposure in non-tumorigenic human osteogenic sarcoma
