Fungi of the genus Penicillium produce unique and chemically diverse biologically active secondary metabolites, including indole alkaloids. The role of dysregulated hepatocyte growth factor (HGF) and its receptor, c-Met, in the development and progression of breast carcinoma is documented. The goal

5,6,11,12,17,18-Hexahydrocyclonona[1,2-b:4,5-b*:7,8-b**]triindole (CTr) is a major digestive product of indole-3-carbinol (I3C) from Brassica vegetables and exhibits strong estrogenic activities. CTr increases proliferation of estrogen-dependent breast tumor cells, binds with strong affinity for the

Depletion of estrogen receptor in human breast tumor cells by a novel substituted indole that does not bind to the hormone binding domain.

Steroidal antiestrogens appear to have at least two major modes of action in breast cancer cells, direct antagonism of estrogen binding to its receptor and depletion of estrogen receptors (ER) due to inhibition of dimerization of the receptor and a resultant destabilization of the receptor protein.

Multiple molecular targets of indole-3-carbinol, a chemopreventive anti-estrogen in breast cancer.

The mechanism of action of the anti-estrogen indole-3-carbinol (I3C), present in cruciferous vegetables, is being examined in our laboratory with a view to promote the use of this naturally occurring chemopreventive as an alternative to synthetic anti-estrogens in human breast cancer. Our previous

Indole-3-carbinol (I3C) inhibits cyclin-dependent kinase-2 function in human breast cancer cells by regulating the size distribution, associated cyclin E forms, and subcellular localization of the CDK2 protein complex.

Indole-3-carbinol (I3C), a dietary compound found in cruciferous vegetables, induces a robust inhibition of CDK2 specific kinase activity as part of a G1 cell cycle arrest of human breast cancer cells. Treatment with I3C causes a significant shift in the size distribution of the CDK2 protein complex

Indole-3-carbinol disrupts estrogen receptor-alpha dependent expression of insulin-like growth factor-1 receptor and insulin receptor substrate-1 and proliferation of human breast cancer cells.

We previously established that Indole-3-Carbinol (I3C), a natural hydrolysis product of glucobrassicin in cruciferous vegetables, arrests the proliferation of estrogen-dependent human breast cancer cells and induces protein degradation of Estrogen Receptor-alpha (ERα). We demonstrate in human MCF-7

Indole-3-carbinol-induced modulation of NF-kappaB signalling is breast cancer cell-specific and does not correlate with cell death.

Indole-3-carbinol (I3C), a dietary chemopreventive compound, induces cell death in human breast cancer cells by modulating activities of Src and epidermal growth factor receptor (EGFR). The effect of I3C on NF-kappaB, constitutively activated in breast cancer cells, was investigated. Nuclear

Sixty women at increased risk for breast cancer were enrolled in a placebo-controlled, double-blind dose-ranging chemoprevention study of indole-3-carbinol (I3C). Fifty-seven of these women with a mean age of 47 years (range 22-74) completed the study. Each woman took a placebo capsule or an I3C

Indole-3-carbinol (I3C) is a compound occurring naturally in cruciferous vegetables and has been indicated as a promising agent in preventing breast cancer development and progression. In the present study we have investigated the effect of I3C on the cell migration and invasion behavior in estrogen

Despite significant advances in treatment, breast cancer is still the second leading cause of cancer-related deaths in women in the United States. Therefore, significant efforts are being given to develop novel strategies for the prevention of breast cancer in recent years. Our laboratory and others

Indole-3-carbinol inhibits protein kinase B/Akt and induces apoptosis in the human breast tumor cell line MDA MB468 but not in the nontumorigenic HBL100 line.
