Abstract

BACKGROUND: ID-1 gene codes for a helix-loop-helix (HLH) protein that inhibits the DNA binding and transcriptional activation function of these proteins. METHODS: We analyzed ID-1 expression in microarray and RNA Sequencing databases as well as 61 breast cancer tissues compared with adjacent non-cancerous tissues (ANCTs). RESULTS: Expression analysis of ID-1 gene in two microarray datasets and RNA sequencing data showed down-regulation of ID-1 in tumoral tissues compared with normal tissues. However, ID-1 expression analysis in tumoral tissues and ANCTs obtained from 61 patients revealed its over-expression in tumoral tissues. A negative association was detected between ID-1 expression levels and ER status. CONCLUSION: ID-1 expression may be implicated in the pathogenesis of breast cancer especially in patient with ER negative status. © 2019 - IOS Press and the authors.
