To obtain global data on polyadenylation of mRNAs, we fractionated the mRNAs according to their poly(A) tail length using a poly-U sepharose column followed by differential elution at five temperatures. Five mRNA fractions with distinct ranges of poly(A) tail length were then hybridized to microarr...

The relative amount of RNA polymerase II (Pol II) associated with a given ORF provides an estimate for transcriptional efficiency. We therefore established a systematic approach to measure Pol II occupancy using chromatin immunoprecipitation followed by analysis on microarrays

Current strategies used to quantitatively describe the biological diversity of lipids by mass spectrometry are often limited in assessing the exact structural variability of individual molecular species in detail. A major challenge is represented by the extensive isobaric overlap present among lipid...

To obtain translational profiles for all mRNAs, polysome preparations are separated according to their size using a sucrose gradient and the mRNAs in each fraction are identified and quantified with DNA microarrays. Starting with exponentially growing cells, we analyzed 12 polysome fractions using D...

Genome-wide translational profiling of rng3-65 compared to wild type cells. We used sucrose gradients to separate RNAs according to the number of associated ribosomes (a surrogate for translational efficiency). Preparation of the extracts and fractionation was carried out as described in Lackner e...

Transcription profiling from young and pre-senescent IMR90 cells, transfected either with hTERT (pBabe-puro-hTERT) or vector control (pBabe-puro). Population doubling values are contained in Characteristics[generation] column.
