Valle Oseguera et al. reported that cmv interleukin 10 (IL-10) can bind to the IL-10 receptor of breast cancer cells and can then activate the signal transducer and activator of transcription 3 (STAT3), which protect breast cancer cells from etoposide-induced apoptosis and also promote cancer cell proliferation [81]. This evidence concerns the gene IL10 and breast carcinoma.
