Important note for readers:
while many of the scientific discoveries and clinical developments listed in
this section are extremely exciting, they are stepping stones in the studies
of Diindolylmethane (DIM) and some of the other key natural ingredients in
Berkeley Immune Support Formula. The exploration of clinical applications for Diindolylmethane is
an emerging science. Only the US FDA has the authority to recognize a compound as a
drug or therapeutic for a particular condition in the US and that only
occurs after the compound has been thoroughly studied and its efficacy
established in four consecutive human clinical trials. At this point in
time, Diindolylmethane and the other natural ingredients in the Berkeley Immune Support Formula are
regarded as dietary supplements and not therapeutics for any specific
condition by the US FDA. The Berkeley Immune Support Formula is a nutritional supplement. Statements on this website have not been evaluated by the US Food and Drug
Administration. The Berkeley Immune Support Formula is not intended to diagnose, treat, cure or
prevent any disease.

DIM In-Vivo Anti-Viral Activity
Through Immune Modulation

Firestone GL, Bjeldanes LF, 3,3′-Diindolylmethane stimulates murine
immune function in vitro and in vivo, Journal of Nutritional
Biochemistry,
published online, 8-20-07.)
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-Gamma for 16 h. B and C, cells
were pretreated with DMSO (control) or 30
µM DIM for 48 h, followed by 0.1 ng/ml of
IFN-Gamma (B) or 10 ng/ml of IFN-Gamma (C) for another 16 h. One
million cells were incubated in 90
µl of
PBS with 10
µl 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).
