The aims of this study were to (1) investigate the antiproliferative properties of WBM, brown A. bisporus (portabella), and Lentinus edodes (shiitake mushroom) on PC3 cancer cells; (2) demonstrate that these properties are exerted through the regulation of both IL-8 and VEGF; and (3) determine the role of NFκB activation in the antiproliferative process of mushroom extracts.
Among PBMCs, natural killer (NK) cells appear to be a major cell type involved in this killing and UV-HSV-1 appears to directly and potently stimulate NK cell expression of CD69, degranulation, cytokine production, and migration to IL-8 in PC3 conditioned medium.
By mining the proteome of PC3 conditioned media, we discovered a signature of chemokine CXC motif ligands (i.e., CXCL3, CXCL5, CXCL6 and CXCL8) that could potentially coordinate increased angiogenesis in androgen-independent prostate cancer and verified their increased expression (P < 0.05) in both in vitro and xenograft models of androgen-independence.
Additionally, the infusion anticarcinogenic effect as to their ability to (a) scavenge free radicals, (b) inhibit cell growth, (c) decrease IL-8 levels and (d) regulate p65 subunit in epithelial colon cancer (HT29) and prostate (PC3) cancer cells was investigated.
