Figure 6: Average values for reductions in centimeters in the outline of the thighs, hips and abdomen, obtained after 1 month (D28) and 2 months (D56) of treatment with Tisochrysis lutea extract and placebo. The centimetric differences obtained by Tisochrysis lutea extract versus the placebo are also shown, within the violet circles. The majority of differences are statistically significant (*P<0.05).

extracted from Tisochrysis lutea activates the genetic program of the beige adipocytes in the white adipose tissue.

Expression of key proteins in the thermogenesis process The expression of both proteins increased dose-dependently. This was by 50% in preadipocytes and by 378% in mature adipocytes. The same pattern was observed for VDAC, whose expression increased by 22% in preadipocytes and by 139% in mature adipocytes. The increase in UCP1 expression after incubation with the active is clearly visible in the microscope images of the treated adipocyte cultures (Figures 3 and 4), compared with untreated cultures (Figures 1 and 2). These results indicate that the gene expression induced by the active extracted from Tisochrysis lutea translates into an increase in the production of proteins essential for thermogenesis.
Biogenesis of new mitochondria Mitochondria are the most important organelles in the processes of respiration and thermogenesis. By using a specific marker, we were able to demonstrate that the increase in the expression of the VDAC protein caused by the active resulted in a significant increase in the number of active mitochondria in the cells. The blue stains visible in the upper panel
are cell nuclei. The active mitochondria are visible in the lower panel as bright red-yellow stains.
