Figure 2From: Cell-specific microarray profiling experiments reveal a comprehensive picture of gene expression in the C. elegans nervous systemMicroarray profiles reveal transcripts enriched in C. elegans neurons. (a) Scatter plot of intensity values (log base 2) for representative hybridization (DMW32; red) of RNA isolated from all larval cells (reference) by mRNA-tagging compared to the average intensity of the reference dataset (green). (b) Scatter plot of a representative larval pan-neural hybridization (DMW33; red) compared to the average intensities for all three larval pan-neural hybridizations (green). (c) Results of a single larval pan-neural hybridization (DMW33; red) compared to average reference intensities (green) to identify differentially expressed transcripts. Known neural genes snb-1 (synaptobrevin, all neurons), unc-17 (VAChT, cholinergic neurons), and unc-47 (VGAT, GABAergic neurons) are enriched (red). Depleted genes include two muscle-specific transcripts (unc-15, paramyosin, and tni-3, troponin) and a germline-specific gene (him-3) (green). (d,e) Pairwise comparisons of individual hybridizations. Coefficient of determination (R2) values for all pairwise combinations of reference hybridizations (d) and for all pairwise combinations of larval pan-neural hybridizations (e) indicate reproducible results for both reference and experimental samples.Back to article page
