In some cases we found a relevant expression change, for example the transcript coded by PBPRA0243a gene (a hypothetical protein) increases its abundance more than seven times increasing hydrostatic pressure from 0.1 to 28 MPa.
The data was plotted as a relevant expression calculated as 2−ΔΔCt, where the cycle threshold is the beginning of the logarithmic amplification of the probe set, and ΔCt is the difference of the target gene Ct subtracted from the housekeeping gene Ct.

All throughout history, frescoed halls or wall-sized paintings have represented a relevant aspect of artistic expression together with regular-sized paintings performed on wood or canvas.
