General description
Procedures such as cDNA synthesis, expression profiling and others require separation of mRNA from the vastly more abundant rRNA and tRNA. The GenElute mRNA kits provide convenient procedures for isolating polyadenylated mRNA from previously prepared total RNA or directly from mammalian cells and tissues.
For direct mRNA preparation, cells or tissues are disrupted with SDS/proteinase K digestion to release RNA and eliminate RNases. The kit uses oligo (dT) covalently linked to 1 μm polystyrene beads to capture polyadenylated mRNA by hybridization. The polystyrene beads remain suspended during hybridization, eliminating the need for mixing or rocking, as is common for cellulose or magnetic particles. Polystyrene was also chosen because oligo(dT) polystyrene beads yield cleaner mRNA with fewer stringent washing steps than does the more commonly used oligo(dT) cellulose (2 or 3 wash steps versus 10 or more). With the GenElute kits, mRNA-bead complexes are washed on a microcentrifuge spin filter, and eluted into 10 mM Tris-HCL, pH 7.5.
Up to 107 mammalian cells or 40 mg tissue are lysed and homogenized, either with the filtration columns provided or with a mechanical homogenizer. RNase is eliminated during a 10 minute proteinase K digestion. Sodium chloride is added, and polyadenylated RNA is captured on oligo(dT) polystyrene beads during a 10 minute incubation. For further enrichment, RNA may be released from the beads into fresh lysis solution and recaptured with the original beads. After 3 washes in a spin column, purified mRNA is eluted in 100 μL of 10 mM Tris-HCl, pH 7.4.
The purified mRNA is ready for Northern analysis, reverse transcription and PCR, labeling for arrays, and other common applications.

The GenElute™ Direct mRNA Miniprep kit provides a convenient format to isolate polyadenylated mRNA directly from mammalian cells and tissues. The direct mRNA isolation procedure is based on that of Badley. Up to 107 mammalian cells or 40 mg tissue are lysed and homogenized, either with the filtration columns provided or with
a mechanical homogenizer. RNase is eliminated during a 10 minute proteinase K digestion.

Retinoids are potent growth inhibitory and differentiating agents in a variety of cancer cell types. We have shown that retinoids induce growth arrest in all pancreatic cancer cell lines studied, regardless of their p53 and differentiation status. However, the mechanism
