Nuclear factor I/thyroid transcription factor 1 interactions modulate surfactant protein C transcription.
Surfactant protein C (SP-C; Sftpc) gene expression is restricted to pulmonary type II epithelial cells. The proximal SP-C promoter region contains critical binding sites for nuclear factor I (NFI) and thyroid transcription factor 1 (TTF-1; also called Nkx2.1). To test the hypothesis that NFI isoforms interact with TTF-1 to differentially regulate SP-C transcription, we performed transient trans...
متن کاملNuclear factor I family members regulate the transcription of surfactant protein-C.
Transcription of the surfactant protein-C (SP-C) gene is restricted to Type II epithelial cells in the adult lung. We have shown previously that the 0.32-kilobase pair (kb) mouse SP-C promoter is functional in transient transfection assays of the lung epithelial cell-derived cell line, MLE-15, and that thyroid transcription factor 1 (TTF-1) transactivates promoter activity. The 0.32-kb SP-C pro...
متن کاملHepatocyte nuclear factor 1 is essential for transcription of sodium-dependent vitamin C transporter protein 1.
Transport and distribution of vitamin C is primarily regulated by the function of sodium-dependent vitamin C transporters (SVCTs). SVCT1 is expressed in the small intestine, liver, and kidney, organs that play a vital role in whole body vitamin C homeostasis. Despite the importance of this protein, little is known about regulation of the gene encoding SVCT1, Slc23a1. In this study, we present t...
متن کاملNuclear factor of activated T cells regulates transcription of the surfactant protein D gene (Sftpd) via direct interaction with thyroid transcription factor-1 in lung epithelial cells.
Surfactant protein D (SP-D) plays critical roles in host defense, surfactant homeostasis, and pulmonary immunomodulation. Here, we identify a role of nuclear factor of activated T cells (NFATs) in regulation of murine SP-D gene (Sftpd) transcription. An NFAT-dependent enhancer modulated by NFATs or calcineurin and sensitive to cyclosporin was identified in the Sftpd promoter. Ionomycin and phor...
متن کاملTranscription Factor Functional Protein-Protein Interactions in Plant Defense Responses
Responses to biotic stress in plants lead to dramatic reprogramming of gene expression, favoring stress responses at the expense of normal cellular functions. Transcription factors are master regulators of gene expression at the transcriptional level, and controlling the activity of these factors alters the transcriptome of the plant, leading to metabolic and phenotypic changes in response to s...
