Steroid biosynthesis

The Snoep Lab’s core research efforts are in Computational Systems Biology; a combined experimental, modeling and theoretical approach to quantitatively understand the functional behavior of Biological Systems resulting from the characteristics of their components. Our main focus is on metabolism, of human pathogens such as Plasmodium falciparum, Mycobacterium tuberculosis, but also of breast cancer cell lines, and on modelling disease states such as glucose homeostatis in type 2 diabetes, and ...

The figures 2, 3, 4 and 6 in the main text of the manuscript: "Inhibition of the glucocorticoid-activating enzyme 11β-hydroxysteroid dehydrogenase type 1 drives concurrent 11-oxygenated androgen excess", submitted to FASEB by Lina Schiffer, Imken Oestlund, Jacky Snoep, Lorna C.

HSD11B1 was inhibited in human subcutaneous and omental adipose tissue, and the effect on oxygenated adrogen metabolism was studied.

Surface plots showing the computational analysis of combined HSD11B1/AKR1C3 ratios and HSD11B1 inhibition.

HSD11B1 was inhibited by CBX and the effect of the inhibition on Cortisone and 11KA4 conversion by HSD11B1/AKR1C3 incubations were measured.

HSD11B1 and AKR1C3 transfected cells were mixed at difefrent ratios and effects on cortisone conversion (Fig. 2B) and 11KT production (Fig. 2C) were measured and simulated.
