Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aim of this clinical trial is to examine the effects of phenethyl isothiocyanate (PEITC), a compound derived from cruciferous vegetables, on oral cells with mutant p53. The p53 protein's normal (wild-type) function within cells is to act as a tumor suppressor, or anti-cancer protein. When mutated, the p53 protein not only no longer executes the functions of a tumor suppressor, and it can gain functions as a pro-cancer protein.22 The proposed clinical trial will utilize oral cells collected from subjects who are heavy smokers. Since the subjects are regularly exposed to mutagenic chemicals it is the thought that their oral cells will contain measurable levels of mutant p53. The participants will consume watercress juice, which is rich in PEITC (See Figure 1). Previous studies in the laboratory showed PEITC selectively depletes mutant p53, and not wild type p53, in cell culture. Our hypothesis is that the ITC in the watercress juice will lead to the depletion of mutant p53 within the oral cells. This depletion could lead to a possible clinical application of this compound, such as chemopreventives or oncologic treatments of individuals with oral cancers.
