SCIENTIFIC BRIEFING FOR
HEALTHCARE PROFESSIONALS AND BIOMEDICAL INVESTIGATORS
Diindolylmethane (DIM)
Immune Modulating Properties
Stimulation of Interferon- γ
sensitivity by increasing IFN-γ
receptors
Stimulation of Interferon-γ,
G-CSF, IL-12 & IL-6
production
Synergy with Interferon-γ
in expression of the MHC-I complex
Selection of Data from the Reference Section
DIM In-Vivo Affect on Key Immune
Modulating Cytokines
In this study DIM was
administered orally at 30mg/kg of body weight.
DIM In-Vivo Anti-Viral Activity
Through Immune Modulation

immune function in vitro and in vivo, Journal of Nutritional

DIM Stimulates Transcript Expression of Interferon-γ
and Related Genes in Human Breast Cancer Cells
Activation and Potentiation of Interferon-γ by DIM:
Stimulation of Interferon-γ Receptor 1 Production
Potentiation of Interferon-γ Mediated Cell Cycle Arrest by DIM in Human Breast Cancer Cells
DIM Enhances Interferon-γ Induced Expression of MHC-I Complex in Human Breast Cancer Cells
(Please Note Section D of this figure.
DIM may be used as an adjuvant
to IFNγ treatment models because of this unique synergistic effect on the MHC-I Complex.
This synergy is currently under investigation for HIV, HPV, Hepatitis
and multiple forms of cancer.)
Fig 8. The expression level of MHC-I complex on the MCF-7 cell
surface. A, cells were treated with different concentrations of IFN γ
for 16 h. B and C, cells
were pretreated with DMSO (control) or 30
΅M DIM for 48 h, followed by 0.1 ng/ml of
IFNγ
(B) or 10 ng/ml of IFNγ
(C) for another 16 h. One
million cells were incubated in 90
΅l of
PBS with 10
΅l of
FITC-conjugated anti-HLA-ABC mouse monoclonal antibody. The fluorescence
intensity was measured by flow cytometry using a Coulter Elite instrument and
analyzed by WinMDI 2.8 software provided by Duke University. D, the expression
of HLA class I complex was calculated as %PC (open bars) and MFV (cross-hatched
bars).
