Effect of storage in additive solution or treatment with Irradiation, mirasol, or intercept on platelet apoptosis-related mRNAs. The figure shows the absolute number of copies of Bcl-xl (A), CLU (B), and BCL2 (C) mRNAs in platelets isolated from samples collected from PCs at 1.5 and 20 hours after treatment with additive solution, Irradiation, mirasol, intercept, or no treatment (control). For each group and time point, the figure shows the individual data (n = 4–6 donors per group), along with their median. All comparisons were two-sided. ∗p < 0.05, namely a statistically significant decrease in the number of mRNA copies at 1.5 or 20 hours for the corresponding group, compared with the control group at the same time point).
