Phytochemical Allyl isothiocyanate and liver cancers

Allyl isothiocyanate is phytochemical containing sulfur in the class of organosulfur compound, found abundantly in horseradish, mustard, wasabi, etc.
Liver cancer is defined as a condition of irregular cell growth in the liver.

In SK-Hep1 human hepatoma cells, Allyl isothiocyanate (AITC) showed to exhibit its anti liver cancer effect through suppressing tumor cell migration and cell behaviors via MMP expression, which plays an important role in breaking down of different human cancers with poor disease prognosis(1).
The phytochemical together with its N-acetylcysteine conjugate also showed the reversal of transcriptase polymerase chain reaction in dose-dependent manner through inhibition of MMP-2/-9 messenger RNA levels which involves in cell proliferation (2). Unfortunately, some researchers suggested that Organosulfur compounds, may induced histone acetylation expression, the enzymes fundamental roles in developmental processes and their deregulation has been linked to the progression of diverse human disorders, such as cancers(4) and thereby favor cell differentiation(3).
