Summary

This gene belongs to the family defined by the mouse resistin-like genes. The characteristic feature of this family is the C-terminal stretch of 10 cys residues with identical spacing. The mouse homolog of this protein is secreted by adipocytes, and may be the hormone potentially linking obesity to type II diabetes. The encoded protein also has an antimicrobial role in skin, displaying antibacterial activity against both Gram positive and Gram negative bacteria. Alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2020]

Forensic Context

A study in humans demonstrated that the RETN (RETN) is a core biomarker for sepsis, showing strong positive correlation and significantly higher expression in sepsis patients compared to healthy controls [Wang et al. DOI:10.2147/IDR.S380137]. Further research confirmed its diagnostic and prognostic value, with higher expression levels linked to an increased mortality risk, and single-cell RNA sequencing localized its expression primarily to monocytes, neutrophils, and macrophage cell lines [Li et al. DOI:10.3389/fimmu.2025.1700704]. A study in mice demonstrated that thermal injury induces significant increases in the RETN gene expression in gonadal adipose tissue and serum protein levels, which peaked at 24 and 48 hours post-burn respectively and correlated statistically with relative insulin resistance evidenced by elevated serum glucose and insulin levels after a glucose challenge [Dasu et al. DOI:10.01.TA.0000053195.32115.9C].
