GREEN TEA- REDUCE PANCREATIC CANCER RISK
The cup of your
favourite green tea is full of health benefits and now researchers have found
that an active compound in green tea also reduces the risk of pancreatic
cancer.
In lab research, EGCG,
the active biologic constituent in green tea, changed the metabolism of
pancreatic cancer cells by suppressing the expression of the LDHA enzyme
associated with cancer.
The researchers also
found an enzyme inhibitor, oxamate – known to reduce LDHA activity – operated
in the same manner: It also disrupted the metabolic system of pancreatic cancer
cells.
“This study will open
the door to a whole new area of cancer research and help us understand how
other foods can prevent cancer or slow the growth of cancerous cells,” said
Wai-Nang Lee, a lead researcher with Los Angeles Biomedical Research Institute
(LA BioMed).
Using sophisticated
metabolic profiling methods, the researchers found EGCG disrupted the balance
of “flux” throughout the cellular metabolic network.
Flux is the rate of
turnover of molecules through a metabolic pathway.
The researchers found
the EGCG disrupted this balance in the same manner that oxamate, a known LDHA
inhibitor did.
“Both EGCG and oxamate
reduced the risk of cancer by suppressing the activity of LDHA, a critical
enzyme in cancer metabolism, thereby disrupting the balance in the cancer cells
metabolic functions,” Lee explained.
The study was
published online in the journal Metabolomics.
