Data Sheet 1_Identification of insulin and glucagon genes in the finless porpoise and the

Liyuan Zhao cloned and characterized the preproinsulin and preproglucagon genes in the finless porpoise. The dataset includes the 110-amino-acid preproinsulin and 180-amino-acid preproglucagon sequences and analyzes islet architecture across different growth stages. It was uploaded to figshare on 2026-04-30 under a CC-BY-4.0 license.

Use Cases

• Comparative genomics analysis based on the conserved primary structure and synteny of insulin and glucagon genes mentioned in the description.
• Studying endocrine cell development based on the distribution of α and β cells across fetal, pregnant, and other life stages described.
• Assessing potential risks from endocrine-disrupting chemicals in cetaceans based on the structural gene information provided.

Strengths

• Includes specific amino acid sequence lengths: 110 aa for preproinsulin and 180 aa for preproglucagon.
• Analyzes islet composition across different developmental stages and genders of finless porpoises.
• Data is shared under a permissive CC-BY-4.0 license.

Limitations

• Dataset is small (346.8 KB) and consists of a single DOCX file, limiting computational analysis scope.
• Column-level documentation and sample data are unavailable, requiring manual inspection after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
