21. Modelling of steatosis and insulin resistance development in human hepatic 3d spheroids : mechanisms and genetic aspects
Abstract : Hepatic steatosis and insulin resistance are common disease manifestations seen in metabolic syndrome, non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes (T2D) patients. Aberrant hepatic lipid accumulation leads to both morphological changes and metabolic alterations in liver function and may cause serious end-stage liver disease. READ MORE

22. Identification of Unique Hematopoietic Stem Cell Properties
Abstract : Hematopoietic stem cells (HSC) are sufficient and required for life long production of all blood cell lineages. Steady state HSCs are largely quiescent and we demonstrate that the kinetics of HSC cell cycling are slower compared to more committed progenitor cells also during expansion and self-renewal ex vivo and in physiological conditions.

23. Studies on human sterol 27-hydroxylase with emphasis on its mechanism of regulation and metabolic consequences of a deficient enzyme
Abstract : Sterol 27-hydroxylase (CYP27A1) is a mitochondrial cytochrome P-450 enzyme present in most animal cells. In hepatocytes, CYP27A1 has an important role in connection with biosynthesis of bile acids from cholesterol. READ MORE

24. The role of phosphodiesterase 3B in energy metabolism
Abstract : Energy metabolism at the level of any particular tissue is tightly regulated by hormones, neurotransmitters and cytokines in order to maintain overall energy homeostasis. Any dysfunctions in energy metabolism may lead to more or less severe consequences, with obesity and type 2 diabetes being the most prevalent ones. READ MORE

25. Studies on the mechanism of regulation of bile acid synthesis in humans with some aspects on genetic factors
Abstract : In the present investigation we studied human bile acid synthesis and its regulation both in vivo and in vitro and also evaluated a possible influence of polymorphisms in the CYP7A1 and CYP8B1 genes on bile acid synthesis in vivo. The following observations were made: · Primary human hepatocytes cultured on matrigel under serum-free conditions produced bile acids consistent with the pattern in vivo, i. READ MORE
