FOXF1 Regulates Growth Hormone Variant 1 Title: Transcription Factor FOXF1 Regulates Growth Hormone Variant Gene Expression Authors:

Transcription factor FOXF1 regulates growth hormone variant gene expression.

Deletion analysis of the human growth hormone variant (GHV) promoter in transient transfection studies in BeWo choriocarcinoma and HepG2 cells indicated that the region extending from nt -158/+57 retained full transcriptional activity. DNase I footprint analysis of the fragment revealed a protected region at nt -82/-77, which is in a putative FOXF1/FOXF2 binding site. Supershift assays using an...

Forkhead box F1 regulates tumor-promoting properties of cancer-associated fibroblasts in lung cancer.

Cancer-associated fibroblasts (CAF) attract increasing attention as potential cancer drug targets due to their ability to stimulate, for example, tumor growth, invasion, angiogenesis, and metastasis. However, the molecular mechanisms causing the tumor-promoting properties of CAFs remain poorly understood. Forkhead box F1 (FoxF1) is a mesenchymal target of hedgehog signaling, known to regulate m...

Nuclear Janus-activated kinase 2/nuclear factor 1-C2 suppresses tumorigenesis and epithelial-to-mesenchymal transition by repressing Forkhead box F1.

Progression to metastasis is the proximal cause of most cancer-related mortality. Yet much remains to be understood about what determines the spread of tumor cells. This paper describes a novel pathway in breast cancer that regulates epithelial-to-mesenchymal transition (EMT), motility, and invasiveness. We identify two transcription factors, nuclear factor 1-C2 (NF1-C2) and Forkhead box F1 (Fo...

Comparison of Expression of Growth Hormone-Releasing Hormone and Its Receptor Splice Variant 1 in Different Stages of Endometriosis

FOXF1 transcription factor is required for formation of embryonic vasculature by regulating VEGF signaling in endothelial cells.

RATIONALE Inactivating mutations in the Forkhead Box transcription factor F1 (FOXF1) gene locus are frequently found in patients with alveolar capillary dysplasia with misalignment of pulmonary veins, a lethal congenital disorder, which is characterized by severe abnormalities in the respiratory, cardiovascular, and gastrointestinal systems. In mice, haploinsufficiency of the Foxf1 gene causes ...
