A polyphenol-rich reagent, referred to as CSC, was isolated from cigarette smoke condensate and shown to prime purified human neutrophils. A mouse monoclonal anti-idiotypic antibody directed against the polyphenol-reactive determinants on a rabbit polyclonal anti-tobacco glycoprotein antibody was generated and shown to also prime neutrophils. After priming(More)
Ras and Rho small GTPases possessing a C-terminal polybasic region (PBR) are vital signaling proteins whose misregulation can lead to cancer. Signaling by these proteins depends on their ability to bind guanine nucleotides and their prenylation with a geranylgeranyl or farnesyl isoprenoid moiety and subsequent trafficking to cellular membranes. There is(More)
SmgGDS is a guanine nucleotide exchange factor with the unique ability to activate multiple small GTPases, implicating it in cancer development and progression. Here, we investigated the role of SmgGDS in prostate cancer by studying the expression of SmgGDS in benign and malignant prostatic tissues. We also probed SmgGDS function in three prostate carcinoma(More)
