In estrogen -sensitive human breast cancer cells challenged with 17β-estradiol, I3C has been found to inhibit the transcription of estrogen-responsive genes without binding to either ERβ or ERα (47, 48) . In fact, the binding of I3C to AhR was shown to trigger the proteasome -dependent degradation of ERα (49) . I3C-induced loss of ERα resulted in the downregulation of ERα-responsive gene products like the transcription factor GATA3. Since GATA3 regulates the transcription of the ERα coding gene ESR1, I3C prevented the synthesis of new ERα transcripts and proteins , eventually abolishing the ERα signaling pathway. The disruption of the GATA3/ERα cross-regulatory loop by I3C ultimately halted ERα-dependent cell proliferation (49) . Acid condensation products of I3C that bind and activate AhR may also inhibit the transcription of estrogen-responsive genes by competing for co-activators or increasing ERα degradation (14 , 50) . I3C treatment also affected the expression of other ERα-responsive genes, including those coding for insulin-like growth factor-1 receptor (IGFR1) and insulin receptor substrate-1 (IRS-1), involved in cell proliferation and deregulated in breast cancer ( Figure 5 ) (51) .

Bromazepam is commonly involved in drug overdoses. [48] A severe bromazepam benzodiazepine overdose may result in an alpha pattern coma type. [49] The toxicity of bromazepam in overdosage increases when combined with other CNS depressant drugs such as alcohol or sedative hypnotic drugs. [50] Bromazepam is the most common benzodiazepine involved in intentional overdoses in France . [51] Bromazepam has also been responsible for accidental poisonings in companion animals. A review of benzodiazepine poisonings in cats and dogs from 1991-1994 found bromazepam to be responsible for significantly more poisonings than any other benzodiazepine. [52]
