Human sera of low and high CRP sub-groups differentially affect gene expression. (A) Changes in SCD1 mRNA expression following treatment of human sera from subjects consuming walnut oil. * indicates significant difference from baseline and between CRP sub-groups (P < 0.01). (B) Quantification of SCD1 protein. Value of baseline sera treated cells of low CRP sub-group was normalized as 100. Bars not sharing the same letters differ (P < 0.05). (C) Changes in membrane transporters ABCA1 mRNA following human sera treatment. (D) Changes in ABCA1 proteins categorized by baseline CRP level. In the GLM model, age, gender, BMI, and glucose are served as covariates and ID number as dummy variable.
