Green Tea Protects Cells From Cancer-Causing DNA
Damage
Study description: Researchers exposed human
lymphoid cells to
a substance called (+/-)-anti-benzo[a]pyrene diol epoxide (BPDE), which is known to induce the kind of DNA damage that
can lead to lung cancer. Some of the human lung cells were from
people with lung cancer, some from people without cancer.
Type of study: "Test-tube"
What happened: When green tea extract was added
to cells from either group prior to exposure to BPDE, there was a "notable reduction"
in DNA damage.
Researchers' conclusion: These findings
"demonstrated the chemopreventive effects of green tea extract" on deliberately-induced DNA damage that might otherwise lead to cancer.
