Figure 1. P2RX7 gene expression in peripheral blood mononuclear cells from healthy volunteers.

P2RX7 RNA expression was increased by sleep deprivation in men (filled diamonds) and women (open triangles). Blood draw (x-axis) was at 7 p.m. and thereafter once every 6 hours. Sleep deprivation was at time points #6, #7, #8 and #9. RNA levels are the normalized average of exon expression across the entire RefSeq transcript. Diamonds and triangles indicate mean and error bars indicate SEM.
