  • Hypoxia-induced nitric oxide release by luminal cells stimulates proliferation and uPA secretion of myoepithelial cells in a bicellular murine mammary tumor

    by Martin Alejandro Krasnapolski, Catalina Lodillinsky, Elisa Bal De Kier Joffé, Ana María Eiján

    LM38 murine mammary adenocarcinoma model is formed by LM38-LP (myoepithelial and luminal), LM38-HP (luminal) and LM38-D2 (myoepithelial) cell lines. In a previous work, we had shown that LM38-HP and LM38-D2 cell lines are less malignant than the bicellular LM38-LP cell line.


  • Is the Epithelial-to-Mesenchymal Transition Clinically Relevant for the Cancer Patient?

    by Martin A. Krasnapolski, Laura B. Todaro, Elisa Bal de Kier Joffe

    Epithelial-to-mesenchymal transition (EMT) is a transdifferentiation process by which a fully differentiated epithelial cell acquires mesenchymal traits, and therefore, mesenchymal abilities such as motility and invasiveness. It is a pivotal physiological process involved in embryogenesis (Type 1 EMT) and in wound healing and tissue remodeling (Type 2 EMT), which, some authors claim, but there are still some controversies, has also been co-opted by tumor cells to increase their malignant potential (Type 3 EMT). Many biomarkers of Type 3 EMT have been characterized and classified into functional categories (i.e., extracellular proteins, cell surface molecules, cytoskeletal markers, transcriptional factors, and, recently, micro RNAs). The extra and intracellular signals that lead to EMT are only starting to be understood, but there is a consensus that Ras and TGF-beta signaling must converge with NF-κB in order to achieve a full EMT. The most classical experimental model is the induction of EMT by TGF-beta in cultures of epithelial cells. Other pathways involving GSK3b, and Wnt/beta-catenin, are also implicated. Ultimately, every EMT-inducing pathway will activate any of the E-cadherin transcriptional repressors (ZEB1, ZEB2, Twist, Snail or Slug). Although in the pre-clinical setting, EMT has also been related to an accelerated tumor progression and to an increased resistance to conventional chemotherapy. In this sense, several groups are beginning to use EMT as a predictive marker of response to treatment. Finally, two chemicals targeting TGF-beta are in clinical trials and many laboratories have initiated studies to use other EMT-related molecules as a therapeutic target for the cancer patient with some modest, but encouraging results.
