In this phase II study we assessed the efficacy of bryostatin-1 (NSC 339555) in metastatic melanoma patients when given intravenously either once a week at a dose of 25 microg/m2 per day over 24 h for 3 weeks or at 40 microg/m2 per day over 72 h ever

In this study the effect of various Protein kinase C (PKC) activators/tumour promoters on the maturation and activity of human peripheral blood monocytes was examined. Monocytes were cultured in the absence or presence of various PKC activators for u

Retroviral infection is associated with immunosuppression, which has been shown to be due, in part, to the action of the envelope protein p15E. We studied a synthetic peptide (CKS-17) homologous to a highly conserved domain of the retroviral envelope

The seminal discovery in 1988 that selective protein kinase C (PKC) activators induce multidrug resistance (MDR) in human cancer cells spawned several years of intensive investigations; these studies were primarily directed at the question of whether

We investigated the ubiquitination and degradation of a tumor antigen, the HER-2/neu (HER-2) protooncogene product which is overexpressed in epithelial cancers. HER-2 degradation was investigated in the ovarian tumor line, SKOV3.A2, that constitutive

The natural product resveratrol is a potent antagonist of phorbol ester-mediated tumor promotion and in vitro cellular responses to phorbol-ester tumor promoters, but it is only weakly inhibitory against the phosphorylation of conventional exogenous

Identification of naturally processed peptides recognized by tumorspecific CTLs may lead to epitope-specific tumor vaccines. Because these epitopes may be expressed differently on epithelial tumors and may differ in their ability to induce CTL in viv

We recently reported that the peptide substrate analog Arg-Lys-Arg-Cys-Leu-Arg-Arg-Leu (RKRCLRRL) irreversibly inactivates the protein kinase C (PKC) isozymes alpha, beta, and gamma in a dithiothreitol-sensitive manner by an active site-directed mech

The high affinity receptor of phorbol-ester and related tumor promoters is the isozyme family protein kinase C (PKC). Activation of PKC by the phorbol esters is a pivotal event in phorbol ester-mediated tumor promotion. PKC activation is also implica

We evaluated the therapeutic efficacy against murine drug-sensitive and drug-resistant tumor of a combination chemotherapy regimen comprising intravenous administration of doxorubicin (DXR) plus oral administration of the staurosporine analogue CGP 4
