Figure 1. Plasmatic B4GALTs and ST6GAL1 activities in dependence of age.

Figure 1

A., C., E. plasmatic B4GALTs; B., D., F. plasmatic ST6GAL1. A and B: regression analysis of enzyme activities in subjects of different ages; C and D: activity of the two enzymes in different age groups; E and F: activity of the two enzymes in offspring of centenarians (OC) or in age- matched offspring of non-long lived parents (NLPO). A: R2 linear (N = 125, all subjects) = 0.466; p < 0.00001. B: R2 quadratic (N = 125, all subjects) = 0.292; p < 0.00001; R2 linear (N = 125, all subjects, dashed line) = 0.0001 p N.S.; R2 linear (N = 102, only adults) = 0.216; p < 0.00001. Comparison of the two glycosyltransferase activities in different age-groups (C and D) and in NLPO and OC (E and F). C-F: *p < 0.05; **p < 0.01; ***p < 0.001 according to Kruskal-Wallis non parametric test.
