Research Supports CellQuest Formulas Role in Inhibiting Proteasomal Activity in Cancerous Cells

CLEARWATER, Fla. – (July 22, 2003) – Lab research conducted at the H. Lee Moffitt Cancer Center & Research Institute in Tampa, Fla. indicates that an extract of the musaceas (plantain and banana) plant may play a role in the battle against cancer, supporting anecdotal evidence from patients and healthcare providers.

Previous studies have shown that musaceas extract contains high levels of polyphenols, substances that exhibit anti-carcinogenic activity. The extract is also the basis for the patented formula manufactured by the study’s sponsor, CellQuest, Inc. (, under the brand name CellQuest.

In the study, directed by Q. Ping Dou, Ph.D., lead investigator and an associate professor of biochemistry and molecular biology with Moffitt’s Drug Discovery program, the likely active ingredients of CellQuest -- hydrolyzed tannins -- were tested in varying concentrations on human leukemia Jurkat T cells, prostate cancer cells, breast cancer cells and normal, non-cancerous cells.

The typical strategy of many cancer treatments is to bring about “apoptosis,” or programmed cell death, in tumor cells. Certain proteins and enzymes such as proteasomes help tumor cells proliferate while simultaneously inhibiting the immune system’s natural ability to cause death in the diseased cells.

The Moffitt study bears out the hypothesis that CellQuest inhibits proteasomal activity in cancerous cells, halting their growth and inducing death of the cells. The study also found that CellQuest had no effect on the body’s human natural killer cells, which aid the immune system in eradicating unwanted cell growth, or on normal healthy cells. This seems to support CellQuest’s ability to selectively target tumor cells, in contrast to the typically non-discriminating action of most conventional therapies.

CellQuest President Edward Ameen comments: “While we are obviously encouraged with the results of Dr. Dou’s research and anecdotal reports, we realize that more extensive research is key if we are to conclusively demonstrate the efficacy of the musaceas plant extract in boosting the body’s immune system.”
