However, it does not decrease further during postnatal development. The example of the slope of the logarithmic regression line for detail (N) and scale (ε) is presented in Figure 3. As with DB, similar results in terms of complexity reduction were obtained after application of smoothing filter. Average smoothed DB(small) was 1.560 ± 0.021 for newborn mice, 1.529 ± 0.022 for mice aged 10 days, 1.526 ± 0.024 for mice aged 20 days and 1.509 ± 0.022 for animals aged 30 days (Fig. 4). Statistically highly significant difference was detected between the groups (F = 6.91, P < 0.001)

and after post-hoc analysis, fractal dimension in animals aged 10 days, 20 days and 30 days was significantly lower (P < 0.05, P < 0.01 and P < 0.001) when compared to controls (Fig. 4). Similarly as with Ferroptosis cancer DB, there was no statistically significant difference (P > 0.05) Saracatinib chemical structure between animals aged 10 days and 20 days, 10 days and 30 days, or between 20 days and 30 days. The average smoothed DB(biggest) for newborn mice was 1.452 ± 0.020 and in older animals the dimension (1.417 ± 0.024, 1.412 ± 0.034 and 1.386 ± 0.029 for animals aged 10 days, 20 days and 30 days, respectively, Fig. 4) was significantly lower (P < 0.05, P < 0.05 and P < 0.001, respectively). There was no statistically

significant difference (P > 0.05) between animals aged 10 days and 20 days, 10 days and 30 days, or between 20 days and 30 days. Dipeptidyl peptidase These results indicate a loss of MDC chromatin complexity immediately after birth, with fractal dimension values remaining low in older animals. Average lacunarity of chromatin structure was 1.354 ± 0.064

in newborn mice. In 10-day-old animals average lacunarity increased (1.452 ± 0.129); however, the difference was not statistically significant (P > 0.05). Lacunarity increased further in older animals (in mice aged 20 days 1.476 ± 0.069) and the increase became statistically significant in mice aged 30 days (compared with newborn animals, 1.481 ± 0.075, P < 0.05, Table 1). There was no statistically significant difference in any other group pairs (10 days vs 20 days; 20 days vs 30 days, Fig. 5). In Table 2, P-values for trends are presented for DB, DB(small), DB(biggest), lacunarity, ASM and IDM. Statistically significant trend between the age groups was detected in DB, DB(small), DB(biggest) and lacunarity. When we compared the values of fractal dimension and lacunarity for individual chromatin structures, we found statistically significant negative correlation between these two parameters in all four age groups (Fig. 6). The strongest correlation was observed in the group of newborn mice and mice aged 30 days (Fig. 6A,D, P < 0.0001, R = −0.45, n = 160). The plotted values of fractal dimension and lacunarity for each age group can be seen in Figure 6. These results indicate that the values of chromatin fractal dimension decreases as the chromatin lacunarity increases and vice versa.
