description Background and purpose: after heart diseases and accidents, cancer is considered the third cause of death in Iran (1), and is a major health problem not only in Iran but also in many developed and developing countries. (2). Breast cancer is a disease in which breast cells grow out of control. This disease has different types based on the type of breast cells that become cancerous. Breast cancer accounts for about one-third of all types of cancer in the female population and is the main cause of cancer-related deaths in women worldwide (3). Estrogen receptor-α is one of the isoforms of estrogen receptor encoded by the ESR1 gene. ESR-α is a nuclear receptor that acts as a ligand-dependent transcription factor (4). After binding of estrogen, ESR-α binds to the estrogen response regions in the promoter of the target genes and causes changes in the expression of the target genes (5). The present study investigates the expression level of the estrogen receptor gene (ESR1) and long non-coding RNAs (lncRNAs) related to It investigates the allele frequency and genotype of single nucleotide polymorphism (SNP) rs2234693 in ESR1 gene in patients with breast cancer. Materials and methods: In this case-control study, the expression of ESR1 and related coding and non-coding RNAs were investigated by microarray (17 control samples and 104 patient samples), TCGA RNAseq (on 113 normal samples, 1102 primary tumors and seven Metastatic tumor samples) and data analysis was done by R Studio and limma, and ENCORI and GEPIA2 databases. Evaluation of microRNA interaction was done by miRWalk and lncRNA interaction finding was done by lncBase 3. Protein-protein interaction was analyzed by STRING and survival and correlation analysis by GEPIA2 and ENCORI. Pathway enrichment and gene ontology (GO) analyses were performed by KEGG and Enrichr and SNP analysis was performed by RFLP test. Results: ESR1 gene expression was increased in breast cancer and miR-15a-3p gene had a significant interaction with ESR1 and lncRNA OIP5-AS1. OIP5-AS1 and ESR1 had significant positive expression in patient samples. The frequency of TC, TT, and CC genotypes in healthy people was 65%, 15%, and 20%, respectively, and in the patient group it was 38.5%, 38.5% and 23%. There was a significant difference in the prevalence of ESR1 gene genotypes between patients and controls. Conclusion: ESR1 polymorphism may be associated with an increased risk of breast cancer and rs2234693 T>C SNP can be considered a strong marker for breast cancer screening. OIP5-AS1 may regulate breast cancer progression by altering ESR1 expression regulation.
