Bayesian Shrinkage Estimation Of The Relative Abundance Of Mrna Transcripts Using Sage, Jeffrey S. Morris, Keith A. Baggerly, Kevin R. Coombes

Serial analysis of gene expression (SAGE) is a technology for quantifying gene expression in biological tissue that yields count data that can be modeled by a multinomial distribution with two characteristics: skewness in the relative frequencies and small sample size relative to the dimension. As a result of these characteristics, a given SAGE sample may fail to capture a large number of expressed mRNA species present in the tissue. Empirical estimators of mRNA species’ relative abundance effectively ignore these missing species, and as a result tend to overestimate the abundance of the scarce observed species comprising a vast majority of …

Comparative Analysis, Gene Organization And Expression Of Canine Tcte1l, Kui Li, Qi Zhang, Jennifer L. Johnson, Gustavo D. Aguirre

Gustavo D. Aguirre, VMD, PhD

The murine t-complex-associated testis-expressed 1-like gene (TCTE1L) of the dog was cloned, characterized, and compared to the human ortholog. The characterized region of cDNA includes 351 bp of coding sequence which encodes a protein of 116 amino acids. The canine gene, spanning about 8.5 kb sequence, consists of 5 exons, with the initiation and stop codons found in the first and last exons, respectively. The comparative analyses reveal the evolutionarily conserved exonic and intronic regions, as well as gene flanking sequences. A 2.1 kb transcript was ubiquitously expressed in all the tissues examined, and secondarily down-expressed in the …
