1. Two mouse cDNAs encoding the non-muscle-specific or brain isoform (type B, Pgam1) and the muscle-specific isoform (type M, Pgam2) of phosphoglycerate mutase (PGAM) were isolated and characterized. Pgam1 contains a 765 bp open reading frame (ORF) coding for a 254-residue protein while Pgam2 contains a 762 bp ORF coding for a 253-residue protein. The deduced proteins of mouse Pgam1 and Pgam2 are highly similar to those of human and rat (> or = 93% similarity). Northern blot analysis showed that the expression patterns of Pgam1 and Pgam2 were distinct. Pgam1 was expressed as a 2.1-kb transcript highly in brain and kidney and moderately in liver, thyroid, stomach and heart, whereas Pgam2 was expressed as a 1.0-kb transcript highly in muscle, testis and moderately in heart and lung, but was not detectable in the other six tissues examined. Transfecting the cDNA fragments containing the entire ORFs of these two cDNAs into COS7 cells for transient expression, respectively, the enzyme activities of mouse Pgam1 and Pgam2 were detected to be 2.2-2.5 times of those of COS7 cells and COS7 cells transfected with vector, proving the validity of mouse Pgam1 and Pgam2 cDNAs we report here. Pgam1 and Pgam2 were assigned to 116.16 cR from D19Mit52 and 29.57 cR from D11Mit129, respectively, by radiation hybrid method. The partial genomic sequence of Pgam2 was determined, which showed that mouse Pgam2 consisted at least three exons and two introns. In addition, a pseudogene of Pgam1, Pgam1-ps1, was identified from mouse genomic sequence. PMID: [11250083] 

2. The National Institutes of Health's Mammalian Gene Collection (MGC) project was designed to generate and sequence a publicly accessible cDNA resource containing a complete open reading frame (ORF) for every human and mouse gene. The project initially used a random strategy to select clones from a large number of cDNA libraries from diverse tissues. Candidate clones were chosen based on 5'-EST sequences, and then fully sequenced to high accuracy and analyzed by algorithms developed for this project. Currently, more than 11,000 human and 10,000 mouse genes are represented in MGC by at least one clone with a full ORF. The random selection approach is now reaching a saturation point, and a transition to protocols targeted at the missing transcripts is now required to complete the mouse and human collections. Comparison of the sequence of the MGC clones to reference genome sequences reveals that most cDNA clones are of very high sequence quality, although it is likely that some cDNAs may carry missense variants as a consequence of experimental artifact, such as PCR, cloning, or reverse transcriptase errors. Recently, a rat cDNA component was added to the project, and ongoing frog (Xenopus) and zebrafish (Danio) cDNA projects were expanded to take advantage of the high-throughput MGC pipeline.

3. Kinases play a prominent role in tumor development, pointing to the presence of specific phosphorylation patterns in tumor tissues. Here, we investigate whether recently developed high resolution mass spectrometric (MS) methods for proteome and phosphoproteome analysis can also be applied to solid tumors. As tumor model, we used TG3 mutant mice carrying skin melanomas. At total of 100 microg of solid tumor lysate yielded a melanoma proteome of 4443 identified proteins, including at least 88 putative melanoma markers previously found by cDNA microarray technology. Analysis of 2 mg of lysate from dissected melanoma with titansphere chromatography and 8 mg with strong cation exchange together resulted in the identification of more than 5600 phosphorylation sites on 2250 proteins. The phosphoproteome included many hits from pathways important in melanoma. One-month storage at -80 degrees C did not significantly decrease the number of identified phosphorylation sites. Thus, solid tumor can be analyzed by MS-based proteomics with similar efficiency as cell culture models and in amounts compatible with biopsies. PMID: [19367708]
