We examine the potential of Kras as a metabolic target in lung cancer using the KrasLSL-G12D lung cancer model. We demonstrate that mutant Kras drives a lipogenic gene expression program, and that fatty acid synthesis is important in Kras-induced tumorigenesis.
De novo lipogenesis represents a therapeutic target in mutant Kras non-small cell lung cancer.

Drosophila H1 regulates the genetic activity of heterochromatin by recruitment of Su(var)3-9.
Specimen part
View SamplesIndicated cells were subjected to RNAi against linker histone H1, Nautilus (control), or GFP (control). RNA was isolated and subjected to Affymetrix GeneChIP Drosophila Genome 2.0 arrays
Drosophila H1 regulates the genetic activity of heterochromatin by recruitment of Su(var)3-9.
Specimen part
View SamplesSalivary glands or larval ovaries were isolated from transgenic flies expressing RNAi targeting Nautilus (control) or linker histone H1 using a Tub-Gal4 driver. Overall design: ~200 larvae were used to isolate salivary glands or ovaries, independently. Total RNA was isolated using Trizol reagent following manufacturer''s guidelines. Then 5 µg of total RNA was separated on a polyacrylamide gel, and 18-29 nt small RNAs were isolated for cloning.

Specimen part
View SamplesGenome-wide approach to identify the cell-autonomous role of Snf2h in lens fiber cell terminal differentiation. Differential gene expression was analyzed in Snf2h lens-conditional knockout and wildtype newborn mouse eyeballs, with subsequent comparison of this data with the Brg1 lens-conditional knockout mouse eyes expression data (GSE25168).
Chromatin remodeling enzyme Snf2h regulates embryonic lens differentiation and denucleation.
