In addition to the conventional hormone-dependent regulation of activity of Estrogen receptor alpha and beta (ESR1(nuclear) and ESR2 respectively), there is a cross-talk between signal transduction pathways and estrogen receptors [1]. Epidermal growth factor (EGF), ...

Sp1 transcription factor (SP1) is a transcription factor involved in gene expression in the early development of an organism. It belongs to the Sp/KLF family of transcription factors. The SP1 transcription factor contains a zinc finger protein motif, by which it binds directly to DNA ...

Hepatocyte nuclear factors (HNFs) are a group of phylogenetically unrelated transcription factors that regulate the transcription of a diverse group of genes. Hepatocyte nuclear factors are expressed predominately in the liver. However, HNFs are also expressed and play important roles in a number ...
