L1 stimulation of human glioma cell motility correlates with FAK activation.

The neural adhesion/recognition protein L1 (L1CAM; CD171) has been shown or implicated to function in stimulation of cell motility in several cancer types, including high-grade gliomas. Our previous work demonstrated the expression and function of L1 protein in stimulation of cell motility in rat glioma cells. However, the mechanism of this stimulation is still unclear.

Modulation of Decapentaplegic gradient during haltere specification in Drosophila.

Suppression of wing fate and specification of haltere fate in Drosophila by Ultrabithorax is a classical example of Hox regulation of serial homology. However, the mechanism of Ultrabithorax function in specifying haltere size and shape is not well understood. Here we show that Decapentaplegic signaling, which controls wing growth and shape, is a target of Ultrabithorax function during haltere specification.
