Genomic analysis of gene expression in C. elegans.
Until now, genome-wide transcriptional profiling has been limited to single-cell organisms. The nematode Caenorhabditis elegans is a well-characterized metazoan in which the expression of all genes can be monitored by oligonucleotide arrays. We used such arrays to quantitate the expression of C. elegans genes throughout the development of this organism. The results provide an estimate of the nu...
متن کاملBroad chromosomal domains of histone modification patterns in C. elegans.
Chromatin immunoprecipitation identifies specific interactions between genomic DNA and proteins, advancing our understanding of gene-level and chromosome-level regulation. Based on chromatin immunoprecipitation experiments using validated antibodies, we define the genome-wide distributions of 19 histone modifications, one histone variant, and eight chromatin-associated proteins in Caenorhabditi...
متن کاملDiscovering Distinct Patterns in Gene Expression Profiles
Traditional analysis of gene expression profiles use clustering to find groups of coexpressed genes which have similar expression patterns. However clustering is time consuming and could be diffcult for very large scale dataset. We proposed the idea of Discovering Distinct Patterns (DDP) in gene expression profiles. Since patterns showing by the gene expressions reveal their regulate mechanisms...
متن کاملGenomic Organization, Expression, and Analysis of the Troponin C Gene pat-10 of Caenorhabditis elegans
We have cloned and characterized the troponin C gene, pat-10 of the nematode Caenorhabditis elegans. At the amino acid level nematode troponin C is most similar to troponin C of Drosophila (45% identity) and cardiac troponin C of vertebrates. Expression studies demonstrate that this troponin is expressed in body wall muscle throughout the life of the animal. Later, vulval muscles and anal muscl...
متن کاملAnalysis of Cell Fate from Single-Cell Gene Expression Profiles in C. elegans
The C. elegans cell lineage provides a unique opportunity to look at how cell lineage affects patterns of gene expression. We developed an automatic cell lineage analyzer that converts high-resolution images of worms into a data table showing fluorescence expression with single-cell resolution. We generated expression profiles of 93 genes in 363 specific cells from L1 stage larvae and found tha...
