Genes exhibiting significant expression differences for EOM versus leg and/or jaw muscle by gene class
| Gene class | No. of genes by Affymetrix (%) | No. of genes by SAM (%) |
|---|---|---|
| Transcription factor | 17 (5.9) | 5 (3.7) |
| Signal transduction | 45 (15.7) | 10 (7.4) |
| Cell cycle/apoptosis | 15 (5.2) | 5 (3.7) |
| Intermediary metabolism, total | 34 (11.8) | 25 (18.5) |
| Glucose | 9 (3.1) | 11 (8.2) |
| Lipid | 10 (3.5) | 4 (3.0) |
| Other | 15 (5.2) | 10 (7.4) |
| Sarcomeric protein/excitation-contraction coupling | 13 (4.5) | 18 (13.3) |
| Channel/transporter | 23 (8.0) | 11 (8.2) |
| Extracellular matrix/cytoskeleton | 25 (8.7) | 10 (7.4) |
| Immunology/cell defense | 14 (4.9) | 1 (0.7) |
| Other | 30 (10.5) | 20 (14.8) |
| Expressed sequence tag | 71 (24.7) | 30 (22.2) |
For Affymetrix analysis, the number of genes (n = 287) equals those exhibiting ≥ 2-fold change in EOM versus leg or jaw. For SAM analysis, the number of genes (n = 135) represents those differing between EOM and the jaw-leg pool by threshold values ≥ 0.4.
