The chemical properties of beer may help in the battle against cancer, due to acids in hops that may have both anti-cancer and anti-inflammatory properties.
The plant that adds flavor, color and bitterness to beer also produces a primary compound that thwarts cancer cells, and two important derivatives of the compound do as well, new research at Oregon State University shows.
Reporting on a number of studies, the Telegraph points out that beer has been found to reduce the risk of kidney stones, heart attacks, strokes, diabetes and Alzheimer’s, while also strengthening bones, treating cataracts and curing insomnia.
Some studies have shown that hops would be particularly effective to ward off breast cancer in women undergoing hormone replacement treatment (HRT) during menopause.
One study from the Indiana University School of Medicine exploring the effects of beer on insomnia showed that a tablespoon of beer is all it takes to release dopamine in the human brain, which can help a person feel more relaxed and therefore more able to fall asleep.
Hops have been used in folk medicine as sedatives and as anti-bacterial functions for thousands of years. According to a recent study, hops also work well for their anti-inflammatory properties. They compared the anti-inflammatory effect of different hops and found that the consumption of hops (in beer) helped stop inflammation because they interfere with inflammation causing compounds.
Unlike the primary compound, xanthohumol, known as XN, the derivatives don’t metabolize into phytoestrogens. Phytoestrogens are plant-based chemicals similar to female sex hormones that help some types of tumors grow and can cause other health problems as well.
The research showed, for the first time, that the derivatives have cancer-fighting effectiveness similar to that of XN in liver and colon carcinomas. That means the two non-estrogenic derivatives are attractive alternatives for testing, along with XN, in future preclinical studies.
The study was published in the International Journal of Molecular Sciences.
Xanthohumol is produced by humulus lupulus, the common hop plant. More than 20 years ago, researchers discovered that XN inhibits cell growth in a variety of cancer cell lines.
“But a potential problem with XN is that enzymes in the liver and the gut microbiota metabolize it into 8- prenylnaringenin, or 8-PN, the most potent phytoestrogen known,” said the study’s corresponding author, Adrian Gombart, professor of biochemistry and biophysics in the College of Science at Oregon State University and principal investigator at OSU’s Linus Pauling Institute.
The derivatives that don’t metabolize into 8-PN are DXN, short for dihydroxanthohumol, and TXN, which refers to tetrahydroxanthohumol.
Earlier, Gombart’s Linus Pauling Institute colleague and co-author Fred Stevens led a study into DXN and TXN’s effects on metabolic syndrome.
“In that previous research we showed that the two derivatives reduced weight gain and improved biomarkers of metabolic syndrome,” Gombart said. “XN had been shown to inhibit proliferation of a variety of cancer cell lines, and in this study, we demonstrated XN’s ability to halt cell growth and kill two liver cancer cell lines and two colon cancer cell lines. We tested liver and colon cancer cell lines because oral consumption of XN and its derivatives can lead to high concentrations in the gut and liver.”
Colorectal cancer is the third most common cause of cancer-related death in the United States, and liver cancer ranks fifth. The incidence of liver cancer, though, has tripled in the last four decades.
“For both of those cancers, discovering new compounds for prevention and treatment is imperative,” Gombart said. “In all the cell lines tested, DXN and TXN inhibited cell growth and caused cell death, as did XN. And for most cell types, DXN and TXN were slightly more potent.”
