Award Description: Role of Phospholipid PI (4, 5)P in Wingless signaling
Project Description: Using a antibody which specifically binds to Phospholipid, PI (4, 5)P our earlier results showed that PI (4, 5) expression pattern is similar to the expression of Wingless protein in the eye imaginal disc. During the current duration of the grant, we extended this observation and showed in mutliple developmental systems during Drosophila Imaginal disc development, we see a correlation between the expression of Wingless protein and the accumulation of PI(4,5)P. Furthermore, gain and loss of function studies show that increase in the levels of Wingless signaling results in an increase in the accumulation of PI(4, 5)P while loss of wingless signaling results in a loss of PI(4, 5)P. These observations suggest a direct link between Wingless signaling and PI(4, 5)P accumulation. In all of the above mentioned studies we always observed increase PI(4, 5)P to be localized to the nucleus. To investigate the possible role of this phospholipid in the regulation of Wingless target genes, we used the Drosophila wing imaginal disc as a model, in which Wg functions in the transcriptional up regulation of Distalless in a graded fashion. Loss of Wg signaling which results in the loss of PI(4, 5) accumulation also results in loss of Distalless expression. Our future studies will focus towards identifying the molecular pathway by which PI(4, 5) regulates Distalless expression downstream of Wg signaling.
