Hepatocellular carcinoma in GNMT-/- mice.

摘要

The article "Glycine N-methyltransferase affects the metabolism of aflatoxin Bl and blocks its carcinogenic effect" from a group under the leadership of Dr. Arthur Chen in Taiwan is misleading (Yen, 2009). The first sentence of the abstract states that "Previously, we reported that glycine N-methyl-transferase (GNMT) knockout mice develop chronic hepatitis and hepatocellular carcinoma (HCC) spontaneously." This implies that these authors were the first to demonstrate this when, in fact, our group (Luka, Mato and Wagner) demonstrated this earlier.
