This paper shows that enteric bacteria can alter the epigenome of intestinal bacteria. This paper was in collaboration with Dr. Lei Lu at the University of Chicago. My role was to perform the DNA methylation experiments and help with the analyses.

This paper shows that gold nanoparticles that are 1.4 nm in diameter are highly toxic to human embryonic stem cells. It also shows that gold nanoparticles that are 5 nm in diameter are not toxic but cause dramatic decreases in DNA methylation levels.

This paper was supported by two NIEHS grants, R01 ES012933 (this grant) and R21 ES021983 (“Effects if Lead on Neuronal Differentiation in Human Embryonic Stem Cell”). The R21 explores using the human embryonic stem cell model to determine how lead exposure affects DNA methylation and gene expression after acute and chronic exposure. We found many parallels to our Drosophila results and we plan to continue this line of research in the competing renewal of our NIEHS R01 grant next year. (Not cited yet – too early).
