Description
The overall aim of the present work was to identify MTG16 functions in leukemia cells. Alterations in quantity of the MTG16 co-repressor might affect gene regulation and cell metabolism in malignant cells. Differentiated cells secure energy for cellular homeostasis largely by mitochondrial oxidation. Whereas, mature cells, proliferating tumour cells including leukemia cells depend on glycolysis and mitochondrial respiration may be low even in oxygenrich environments.The same signal transduction pathways that govern cell proliferation give instructions for nutrient uptake and co-regulate metabolic processes. In this manner, the metabolism of tumor cells, and other highly proliferating cells, is adapted to stimulate anabolic glycolysisdriven processes for incorporation of nutrients into nucleotides, amino acids and lipids to synthesize macromolecules required for growth and proliferation.

Description
Tissue morphogenesis relies on proper differentiation of morphogenetic domains, adopting specific cell behaviours. Yet, how signalling pathways interact to determine and coordinate these domains remains poorly understood. Dorsal closure (DC) of the Drosophila embryo represents a powerful model to study epithelial cell sheet sealing. In this process, JNK (JUN N-terminal Kinase) signalling controls leading edge (LE) differentiation generating local forces and cell shape changes essential for DC. The LE represents a key morphogenetic domain in which, in addition to JNK, a number of signalling pathways converges and interacts (anterior/posterior -AP- determination; segmentation genes, such as Wnt/Wingless; TGF/Decapentaplegic). To better characterize properties of the LE morphogenetic domain, we used microarrays to identify genes whose expression is regulated by the JNK pathway during dorsal closure of the Drosophila embryo.
Publication Title
