Significant gene expression differences in histologically “Normal” liver biopsies: Implications for control tissue
Tarik Asselah, Ivan Bièche, Ingrid Laurendeau, Michelle Martinot‐Peignoux, Valerie Paradis, Dominique Vidaud, Dominique‐Charles Valla, Pierre Bedossa, Patrick Marcellin, Michel Vidaud – 9 May 2008 – Gene expression technologies allow the analysis of gene networks whose expression is associated with specific pathological conditions compared with normal tissue. We hypothesized that histologically normal tissue obtained in different ways (percutaneous or surgical liver biopsies), usually used as normal controls in gene expression studies, could have different gene expression patterns.
