This gene is the putative transforming gene of avian sarcoma virus 17. It encodes a protein which is highly similar to the viral protein, and which interacts directly with specific target DNA sequences to regulate gene expression. This gene is intronless and is mapped to 1p32-p31, a chromosomal region involved in both translocations and deletions in human malignancies. [provided by RefSeq, Jul 2008] CIViC Summary for JUN Gene
Forensic Context
A study in mice demonstrated that the JUN (Jun protooncogene) is a key gene identified in severe burn wounds, with its mRNA and protein expression levels significantly increased in burn tissue compared to normal skin [Guo et al. DOI:10.1155/2022/5220403]. A study in mice demonstrated that a single high-dose chlorpromazine administration did not alter the JUN expression, but repeated high-dose administration for 3 and 4 weeks significantly decreased its mRNA levels in the heart, suggesting a down-regulation to avoid cardiomyopathy [Sakai et al. DOI:10.1016/J.Legalmed.2010.07.005]. In a rat model of heat stroke, transcriptomic sequencing and machine learning identified the JUN as a key target, with its protein expression significantly up-regulated in myocardial tissue and associated with mitochondrial disruption and increased apoptosis, while its pharmacological inhibition improved mitochondrial membrane potential and reduced cell death [Xiang et al. DOI:10.2147/JIR.S517319].
