唾液是一种有用的生物液体,用于疾病的早期检测,但远端肿瘤如何与口腔交流并产生疾病特异性唾液生物标志物尚不清楚。利用体外乳腺癌模型,我们证明了乳腺癌来源的外泌体样微泡能够与唾液腺细胞相互作用,改变其分泌的外泌体样微泡的组成。我们发现唾液腺细胞分泌外泌体样微泡,包封蛋白质和mRNA。我们还发现,与乳腺癌来源的外泌体样微泡的相互作用可以交流和激活唾液腺细胞的转录机制。因此,这种相互作用在转录组学和蛋白质组学上改变了唾液腺细胞来源的外泌体样微泡的组成。
Saliva is a useful biofluid for the early detection of disease, but how distal tumors communicate with the oral cavity and create disease-specific salivary biomarkers remains unclear. Using an in vitro breast cancer model, we demonstrated that breast cancer-derived exosome-like microvesicles are capable of interacting with salivary gland cells, altering the composition of their secreted exosome-like microvesicles. We found that the salivary gland cells secreted exosome-like microvesicles encapsulating both protein and mRNA. We also showed that the interaction with breast cancer-derived exosome-like microvesicles communicated and activated the transcriptional machinery of the salivary gland cells. Thus, the interaction altered the composition of the salivary gland cell-derived exosome-like microvesicles on both the transcriptomically and proteomically.
