Caveolin-1, an integral membrane protein of caveolae found in many cell types, has been suggested as a candidate tumor suppressor. However, the mechanism underlying caveolin-1 decreased expression is not fully understood. The purpose of this study is to investigate the role of aberrant promoter methylation in the regulation of caveolin-1 gene in breast cancer correlated with clinical findings. We used methylation specific PCR, direct sequencing and immunohistochemistry stain methods to explore the role of caveolin-1 gene in the development of breast cancer. We demonstrated that 14 of 55 cases (25.5%) and 4 of 55 cases (7.3%) had methylated CpG-island on caveolin-1 promoter in cancerous and non-cancerous cells, respectively. The frequency of aberrant promoter methylation of breast cancer tissues was significant higher than non-cancerous tissues (p
