The work in my laboratory focuses on two main lines of research. The first has to do with deciphering the mechanisms, at the molecular level, that regulate the interaction of the cell with its microenvironment. For that, different mammary cell culture models are used. The role of the gap junctions, connexins, and their associated proteins, in regulating mammary growth, development and mammary epithelial cell differentiation is investigated. The second line of research, investigates the claimed anti-inflammatory bioactivities in Lebanese indigenous plants commonly used in folk medicine. An endotoxin treated mammary cell culture model that mimics inflammation and in vivo animal models are used for that purpose.
