BACKGROUND Clustering is a key step in the processing of Expressed Sequence Tags (ESTs). The primary goal of clustering is to put ESTs from the same transcript of a single gene into a unique cluster. Recent EST clustering algorithms mostly adopt the alignment-free distance measures, where they tend to yield acceptable clustering accuracies with reasonable computational time. Despite the fact th...
In an effort to identify and characterize genes expressed during multicellular development ill Dictyostelium, we have undertaken a cDNA sequencing project. Using size-fractionated subsets of cDNA from the first finger stage, two sets of gridded libraries were constructed for cDNA sequencing. One, library S, consisting of 9984 clones, carries relatively short inserts, and the other, library L, w...
Peptide deformylases (PDF) behave as monomeric metal cation hydrolases for the removal of the N-formyl group (Fo). This is an essential step in the N-terminal Met excision (NME) that occurs in these proteins from eukaryotic mitochondria or chloroplasts. Although PDFs have been identified and their structure and function have been characterized in several herbaceous species, it remains as yet un...
The zebrafish is an important vertebrate model for the mutational analysis of genes effecting developmental processes. Understanding the relationship between zebrafish genes and mutations with those of humans will require understanding the syntenic correspondence between the zebrafish and human genomes. High throughput gene and EST mapping projects in zebrafish are now facilitating this goal. M...
Finding new protein-coding genes is one of the most important goals of eukaryotic genome sequencing projects. However, genomic organization of novel eukaryotic genomes is diverse and ab initio gene finding tools tuned up for previously studied species are rarely suitable for efficacious gene hunting in DNA sequences of a new genome. Gene identification methods based on cDNA and expressed sequen...
Detection of differentially expressed genes from expressed sequence tags (ESTs) data has received much attention. An empirical Bayesian method is introduced in which gene expression patterns are estimated and used to define detection statistics. Significantly differentially expressed genes can be declared given detection statistics. Simulation is done to evaluate the performance of proposed met...
Using a collection of expressed sequence tag (EST) data, we re-evaluated the correlation of tissue specificity with genomic structure, phyletic age, evolutionary rate and promoter architecture of human genes. We found that housekeeping genes are less compact and older than tissue-specific genes, and they evolve more slowly in terms of both coding and core promoter sequences. Housekeeping genes ...
Psychotherapies for children and adolescents have been tested in hundreds of randomized controlled trials across five decades, and many of these youth therapies have now been classified as empirically supported treatments (ESTs). A burgeoning movement is underway to implement these ESTs in clinical practice settings, but questions arise as to whether the treatments are ready for practice and wh...
Previously, we used heterologous expressed sequence tag (EST) mapping to generate a profile of 4 935 pathogen-response genes of Arabidopsis thaliana. In this work, we performed a computer analysis of this profile, revealing 1 594 non-homologous clustered genes distributed among all A. thaliana chromosomes, whose co-regulation may be related to host responses to pathogens. To supplement computer...
