| Research Abstract |
Recently, sex steroid hormones such as estrogen have been considered to play some roles in lung cancer. In this study, we demonstrated that cigarette smoke condensate (CSC) has estrogenic action through the estrogen receptor in vitro. In lung carcinoma patients, a correlation was found between the patients smoking history and CYP19 expression evaluated using quantitative RT-PCR. Results from our study suggested that CYP19 expression might be increased smoking through the cytokine signal. These findings all suggested that smoking might stimulate the estrogen signals directly and /or indirectly in lung carcinoma tissues.
