An investigation panel at the University of Tokyo plans to make public this week a report indicating that Kazunari Taira, a professor of biochemistry engineering, fabricated a scientific paper on human enzyme experiments, sources said Saturday.

The paper was published by Taira, 53, in an overseas scientific journal in 2003 in which he stated that his research team had succeeded in having E. coli bacteria produce a human enzyme called Dicer — so called as it dices RNA — by implanting a Dicer gene in a plasmid.
