Medical News Today (Internet) 06/14/06 A Research Article, Perspective and e-Letter all published today discuss the use of microarrays to discover genes involved in childbirth. The three papers highlight the complexity of such gene expression analyses but also how crucial it is to make original data available for reanalysis. In the Research Article (Labor-Associated Gene Expression in the Human Uterine Fundus, Lower Segment, and Cervix), Radek Bukowski and colleagues from the University of Texas, Galveston used microarrays to assess labor-associated gene expression profiles in the top, lower part and cervix of the uterus and describe networks of co-regulated and co-expressed genes.
