Like it or not, we are in a motor age and we can no more turn back the clock than we can unsplit the atom.

Computation and visualization were achieved using heatmap.plus package in R. Differentially expressed gene identification By using Cufflinks and cuffdiff, we identified pairwisely differentially expressed genes (DEG) based on the following criteria: fold change ≥2 (or log2 fold ≥ 1) and FDR ≤ 0.05.

Take any price you can get. We're in a buyer's market right now.
