Plateletomics Web site. This figure shows examples of the functionality of the web tool based on PRAX1 data and uses the PCTP mRNA as an example. (A) The user can query the relative expression level among any commonly expressed platelet mRNAs. The queried gene is in red; a set of well-known platelet genes are shown in black for comparison. Relationships of platelet PCTP mRNA levels and demographic features, including (B) age, (C) BMI, (D) gender, and (E) black and white race. Correlations between platelet PCTP mRNA levels and platelet aggregation, including (F) arachidonic acid, (G) ADP, (H) PAR1-AP, and (I) PAR4-AP. (J) Illustration of the capacity to visualize relationships among 4 different variables; in this example, PAR4-AP agonist response (y-axis), platelet PCTP mRNA level (x axis), race (color), and age (size of the data points).
