highly significantP < 2.2E−16
Importantly, the global shift observed with RRP41 knockdown was statistically highly significant ( P < 2.2E−16, Jonckheere trend test) and was not observed with the U2-type introns located immediately up- or downstream of the U12-type introns (Figure 3F ) or in the group of all the U2-type introns in the same genes.
