In this work we analyzed the transcriptome profiles of chicken hepatoma cells (LMH) in response to T0901317, a pharmacological agonist of the liver X receptor (LXR). Through an in silico search for LXRE (LXR response element) consensus sequences in the promoter of genes whose expression was shown to be sensitive to TO901317, we identified a LXRE in the promoter of the LPCAT3 (lysophosphatidylcholine...
The maintenance and differentiation of embryonic stem cells (ES cells) depends on the regulation of gene expression through the coordinated binding of transcription factors to regulatory promoter elements. One of the genes involved in embryonic development is the chromatin factor CP27. Previously, we have shown that NF-Y interacted with the CP27 proximal promoter CCAAT-box. Here we report that CP27...
Forkhead/winged helix transcription factors (Foxs) regulate differentiation, metabolism, and development. Although Foxa1 is expressed in adipocytes, the roles and regulation of Foxa1 in them remain unclear. Here, we found that under the control of C/EBPβ, Foxa1 suppressed lipid accumulation and concomitantly caused a decrease in adipogenic gene expression in adipocytes. Foxa1 was expressed in undifferentiated...
The four-and-a-half LIM protein 2 (FHL2) was originally identified to be expressed abundantly in the heart, as well as in a wide range of tissues demonstrated in various studies. The human FHL2 gene expresses different transcripts which are known to differ only in the 5′UTR region. However, little is known about the functional role of the different variants and the mechanism of gene regulation. In...
TBX3 is a member of the T-box family of genes that encode developmentally important transcription factors. Mutations resulting in decreased levels of functional TBX3 lead to Ulnar-Mammary Syndrome and increased levels of TBX3 have been linked to several cancers. To understand the mechanisms regulating TBX3 expression we have previously cloned the 5′-flanking region of the human TBX3 gene and here...
Periostin (POSTN), an osteoblast-specific secreted protein known to be associated with cell adhesion activity for bone formation and development by the epithelial cell-derived tumors, leads to a significant enhancement in angiogenesis and tumorigenesis. At present, little is known about the mechanisms underlying its transcriptional control either in physiological or neoplastic conditions. In this...
