Causes, Mold: Prevention, Kensler clip 1
Professor Kensler explains their clinical trials in which chlorophyllin was administered as a therapy and the resultant levels of aflatoxin DNA damage products present in urine samples.
Thomas Kensler, Ph.D. is a professor at John Hopkins Bloomberg School of Public Health. His research focuses on the molecular mechanisms involved in the development of cancers linked to exposure to environmental carcinogens. This research has led to potential chemopreventative strategies for liver cancer in populations at high risk for aflatoxin exposure. â€œIt's worth pointing out that in our clinical trial we didn't use vegetables to administer the chlorophyllin. We used tablets that contained 100 mg of chlorophyllin and asked our participants to take one tablet 20 minutes before each meal. We then measured for the presence of aflatoxin molecules in their blood and urine and were able to show that those people who took the chlorophyllin tablet instead of a placebo tablet had much lower levels of aflatoxin DNA damage products coming out in their urine.â€

In this section learn about inexpensive and safe substances being investigated that may decrease the risk of liver cancer.
Aflatoxin, a byproduct of molds, is a potent cancer-causing agent. Long-term exposure to aflatoxin has been linked to increased incidence of liver cancer.
Professor Kensler explains that Aflatoxin is a lipid soluble molecule that is rapidly absorbed and it goes first to the liver where there are enzymes that will chemically biotransform it into a very reactive chemical.
In this section learn how Aflatoxin a contaminating byproduct of mold caused liver cancer in animals and solicited strict guidelines to regulate the levels of Aflatoxin in the U.S. food supply today.
Aflatoxin causes DNA damage and with prolonged exposure to aflatoxin, cells accumulate DNA mutations and thus are at increased risk of developing into cancer cells.
Professor Kensler explains that the importance of aflatoxin and the causation of liver cancer results from a life long series of exposures.
Professor Kensler explains that there is a lot of interest in discovering new classes of chemopreventative agents and foods such as, fruits and vegetables appear to be a very rich source.
Professor Groopman explains that Aflatoxin is produced by a variety of molds and these molds contaminate the grains either outside or they can actually penetrate inside the grains.
Professor Groopman explains that we have an effective vaccine against the hepatitis B virus, but because the transmission of this virus occurs very early in life, we need to have the resources and the ability to vaccinate the world for the rest of the 21s
Mold-contaminated crops can be a serious problem especially in countries where proper storage facilities are limited.
