Figure 4. Bioinformatics analysis of Upf1-bound transcripts with altered expression after SE.

Figure 4

Upf1-bound transcripts whose log2-fold expression was decreased by 1.5 fold or was completely absent from SE samples and whose log2-fold expression was increased 1.5 fold or was completely absent from control samples were used to investigate over- and under-represented GO terms. Numbers of genes in each group are displayed in inset Venn diagram. (a) Biosynthetic and mRNA processes were over-represented in those genes only expressed or decreased in control SN sample. (b) Terms relating to biosynthetic, biological (conversely to control), and GPCR signalling were over-represented in the group of genes that were increased or exclusively bound after SE in SN compartment. (c) RNA processes, GPCR and glutamate signalling were over-represented in the genes that were exclusive to or decreased in control cytoplasm. (d) GO terms related to biological processes, biosynthetic processes, cell signalling, development (Dev.) and G protein coupled receptor (GPCR) signalling were over-represented by the genes that were exclusive to or increased after SE in cytoplasm. There was an under-representation of genes associated with responses to a stimulus in all groups and genes related with immune response were also under-represented in both the SN and cytoplasm fractions for genes exclusive to or decreased in controls.
