Project description:We performed an mRNA-sequencing experiment using Drosophila midgut to find uracil-induced signaling pathways and biological processes in response to uracil. The sequenced reads from Illumina Hiseq2000 that passed quality filters were mapped to Drosophila genome (NCBI build 5.3) using Tophat and then quantitatively analyzed by HTseq at the gene level. By comparing uracil-treated and non-treated samplesl, we profiled uracil-dependent gene expression changes.
Project description:The highly conserved Wnt signaling pathway drives intestinal homeostasis across species. Apc is a negative regulator of Wnt signaling. Loss of function mutations in Apc are found in 80-90% of human colorectal cancers. Importantly, Apc loss is widely known as the key driving event in the disease. We used microarray analysis of adult Drosophila midguts to study the molecular mechanisms regulated upon loss of Apc in the intestine.
