The promoter in this cell line is methylated (epigenetically silenced), thus the reporter genes are not expressed until after the addition of demethylating agents, in which GFP or G418 can be used as a readout in a screening assay for epigenetic reactivation.\u003c\/p\u003e\n\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel identity:\u003c\/strong\u003e EGFP\/G418 Resistant H1299 Cells is supplied as a tumor cell line derived from Human lung.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth properties:\u003c\/strong\u003e Adherent, epithelial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth conditions:\u003c\/strong\u003e PriCoat™ T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) are recommended for optimal cell culture.

When treated with the DNMT inhibitor 5-aza-2′deoxycytidine (DAC) or siRNAs\/shRNAs targeting DNMT1 mRNA, the DAPK1 promoter demethylates, leading to the expression of a fusion transcript containing exons 1-3 and the EGFP-NEO (G418) reporter.
