Itzel Calleja-Macias was awarded a 2007-2008 UC MEXUS-CONACYT Postdoctoral Fellowship to conduct research in the Department of Molecular Biology and Biochemistry at UC Irvine, under the guidance of Professor Hans-Ulrich Bernard. Her postdoctoral research explored the nicotinic acetylcholine receptors and their biological functions in cervical cells. She analyzed the expression of mRNAs and translation of the nicotinic acetylcholine receptor subunits in cervical cells lines as well as the measure of the proliferation of these cells under the stimulus of nicotine. Results from this stay were published in the International Journal of Cancer (2009). Calleja-Macias continues to work as a postdoctoral scholar in Bernard's lab at UC Irvine, where she is studying cholinergic signaling during cervical carcinogenesis.
