PPARγ-regulated promoter 1

A synthetic promoter upregulated by pPARγ activation. Manufactured by [http://2009.igem.org/Team:Heidelberg/Project_Synthetic_promoters RA-PCR].

Usage and Biology

pPARγ activation. During fatty diet, fatty acids are converted to prostaglandins by oxygenases, which activate pPARγ. Image published under [http://en.wikipedia.org/wiki/File:PPAR-diagram.png GNU Free documentation license.]
Peroxisome proliferator-activated receptor γ (PPAR γ) is a transcription factor belonging to the family of nuclear receptors. PPAR γ plays an important role in glucose metabolism and fatty acid storage. PPAR γ is basically activated by ligands like the prostaglandin PGJ2 and through dimerization with retinoid X receptor (RXR). The activated heterodimer binds to the DNA consensus sequence AGGTCANAGGTCA resulting in an increased or decreased transcription of the appropriate gene. The genes activated by PPAR γ initiate the uptake of fatty acids and differentiation of cells to adipocytes. Besides its function in metabolism, PPAR γ was also shown to be correlated with several diseases such as cancer and diabetes. Activation of PPAR γ by synthetic PPAR γ ligands result in an increased glucose uptake. These syntethtic ligands are therefore promising agents in diabetes II treatment. Another synthetic ligand of PPAR γ is able to inhibit the proliferation of different cancer types.

Functional Parameters

pPARγ was induced by 5µM Thiazolidinedione in [http://2009.igem.org/Team:Heidelberg/Eucaryopedia#U2-OS U2OS cells]. Promoter activtiy was then roughly characterized analogous to [http://2009.igem.org/Team:Heidelberg/Measurement REU] by TECAN (automated plate fluorescence reader). This promoter corresponds to clone γL9. (For more accurately characterized promoters created by RA-PCR, see Part:BBa_K203119, Part:BBa_K203111, Part:BBa_K203110, and others)

Characterization of two pPARγ responsive promoters. Clones created by [http://2009.igem.org/Team:Heidelberg/Project_Synthetic_promoters RA-PCR] were screened and two promising clones were characterized by TECAN reads from three biologically independent experiments. Background fluorescence was substracted, and fluorescence levels are plotted relative to Part:BBa_K203112.
