Proximal Promoter of the Surfactant Protein D Gene

Proximal promoter of the surfactant protein D gene: regulatory roles of AP-1, forkhead box, and GT box binding proteins.

Surfactant protein D (SP-D) plays roles in pulmonary host defense and surfactant homeostasis and is increased following lung injury. Because AP-1 proteins regulate cellular responses to diverse environmental stimuli, we hypothesized that the conserved AP-1 motif (at -109) and flanking sequences in the human SP-D promoter contribute to the regulation of SP-D expression. The AP-1 sequence specifi...

the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

Pleiomorphic adenoma gene-like-2, a zinc finger protein, transactivates the surfactant protein-C promoter.

Expression of surfactant protein (SP)-C occurs principally in type II pneumocytes located in the distal lung alveolae. SP-C expression is thought to be primarily regulated by thyroid transcription factor (TTF)-1 and its associated proteins interacting with a previously defined promoter region between -197 and -158 in mice. We screened a human lung cDNA library using a modified yeast one-hybrid ...

Interactions of Surfactant Protein D with Bacterial Lipopolysaccharides . Surfactant Protein D is an Escherichia Coli - Binding Protein in Lavage

Surfactant protein D (SP-D) is a collagenous glycoprotein that is secreted into the pulmonary airspaces by alveolar type II and nonciliated bronchiolar cells. SP-D exhibits Ca"+-dependent carbohydrate binding in vitro and is structurally related to the collagenous C-type lectins, including serum conglutinin, serum mannose-binding proteins, and surfactant protein A. Preliminary studies showed ca...
