Professors of Biology Maria Cuevas and Maria Todd published a paper titled “Microarray Analysis Reveals Overexpression of both Integral Membrane and Cytosolic Tight Junction Genes in Endometrial Cancer Cell Lines” in the Journal of Cancer. The study reports for the first time a comprehensive analysis of 84 tight junction network genes in a panel of endometrial cancer cell lines. The authors identified three genes that were consistently deregulated in endometrial cancer, thus providing potential candidates for the development of both diagnostic markers and novel therapeutic approaches for endometrial cancer.

Professors of Biology Maria Cuevas and Maria Todd received a $12,000 grant from the Joe and Jessie Crump Foundation for Medical Research. The funds will support their current research project titled “Simultaneous Analysis of 84 Tight Junction Genes Involved in Uterine Cancer Progression.” This grant will enable them to expand the scope of their studies and increase the clinical relevance of their research endeavors.

Retired Associate Professor Rebecca Sheller and Professors of Biology Maria Cuevas and Maria Todd published an article in Biological Proceedings Online titled “Comparison of transepithelial resistance measurement techniques: Chopsticks vs. Endohm.” Measurement of transepithelial resistance (TER) is frequently used to determine the strength of tight junctions between epithelial cells in culture. However, the use of different technical approaches to measure TER sometimes results in inconsistent reports for TER readings within the same cell lines. To address this discrepancy, they compared two frequently used approaches (Chopsticks and Endhohm) and two types of polymer inserts (polycarbonate vs. polyester) to measure the TER values of three mammalian cell lines. Their study demonstrated the importance of using a single approach when seeking to measure and compare the TER values of cultured cell lines.

Professors of Biology Maria Todd and Maria Cuevas received a $15,000 grant from the Joe and Jessie Crump Foundation for Medical Research. The funds will support their research aimed at elucidating the role of tight junction destabilization in the development and progression of endometrial cancer. This project will offer research opportunities for undergraduate students majoring in Biology.

Professor of Biology Maria Todd and her co-authors, Dr. Thomas Langan and Dr. Robert Sclafani (both of the University of Colorado Health Sciences Center), published an article in The Journal of Cancer titled “Doxycycline-Regulated p16MTS1 Expression Suppresses the Anchorage-Independence and Tumorigenicity of Breast Cancer Cell Lines that Lack Endogenous p16.” Their study demonstrated the mechanisms by which the p16 gene is inactivated in breast cancer and how replacement of the functional gene results in the suppression of breast tumor growth.
