Newt-omics

Newt-omics provides an integrated molecular resource of expressed sequence tags (ESTs), high-density microarray data, and mass spectrometry-validated peptides to support molecular studies of regeneration in Notophthalmus viridescens.

Key Features:

• Expressed Sequence Tags (ESTs): A central EST dataset comprising approximately 50,000 Sanger-sequenced transcripts from Notophthalmus viridescens.
• Microarray Data: High-density microarray datasets generated from regenerating hearts of Notophthalmus viridescens to profile cardiac regeneration-associated expression changes.
• Peptide Validation: Peptides identified by mass spectrometry that validate 13,810 ESTs as protein-coding sequences.
• Open Architecture: Database architecture designed to accommodate additional high-throughput datasets without requiring structural changes.

Scientific Applications:

• Gene Expression Analysis: Differential gene expression studies across stages of tissue regeneration in Notophthalmus viridescens, including cardiac regeneration.
• Proteomic Studies: Proteome-level analyses using mass spectrometry-validated peptides to identify proteins involved in regenerative processes.
• Comparative Genomics: Investigation of unique sequences lacking homology to publicly available genes for novel discovery and cross-species comparison.

Methodology:

Datasets originate from Sanger sequencing of ESTs, high-density microarray generation from regenerating newt hearts, and mass spectrometry-based peptide identification.
