BCL2 and breast cancer: The correlations between SYT13 and 84 cancer-related gene expression levels in 13 BC cells were evaluated by PCR array analysis, and it was found that the expression levels of several oncogenes, including murine double minute 2 (MDM2), AKT serine/threonine kinase 1 (AKT1), B-cell lymphoma 2 (BCL2), estrogen receptor 1 (ESR1), and CDK4, were positively correlated with those of SYT13 (Table 1 and Table S2).
