1. Functional collaboration between HLH transcription factors in B cell development
Abstract : The cells in B cell development can be divided into several subgroups or fractions, e.g. early-pro-B-, pro-B, large-pre-B-, small-pre-B-, immature and mature B cells, where the stages reflect the maturity degree of the cells. READ MORE

2. From Single Gene to Whole Genome Studies of Human Transcription Regulation
Abstract : Transcriptional regulation largely determines which proteins and the protein levels that are found in a cell, and this is crucial in development, differentiation and responses to environmental stimuli. The major effectors of transcriptional regulation are a group of proteins known as transcription factors, which importance is supported by their frequent involvement in mendelian and complex diseases.

3. Maf transcription factors in beta cell function
Abstract : Diabetes mellitus is metabolic disorder caused by a defect or lack of beta cell-produced insulin that controls blood glucose homeostasis. In addition to glucose, insulin secretion is regulated by the autonomic nervous system (ANS); the neurotransmitter acetylcholine as well as monoamines, such as dopamine, serotonin, melatonin and norepinephrine.

4. Genetic and Genomic Analysis of Transcriptional Regulation in Human Cells
Abstract : There are around 20.000 genes in the human genome all of which could potentially be expressed. However, it is obvious that not all of them can be active at the same time. Thus, there is a need for coordination achieved through the regulation of transcription. READ MORE

5. Inflammatory transcription factors in atherosclerosis
Abstract : Transcription factors such as nuclear factor-kB (NF-kB), activator protein-1 (AP-1) and peroxisome proliferator-activated receptors (PPARs) may play important roles in atherogenesis, by regulating chronic subclinical vascular inflammation. In the first study, we showed that VLDL activates the proinflammatory transcription factor NF-kB in endothelial cells both in vitro and in vivo. READ MORE
