Does label-free LC-MSe in tissue and serum reveal protein networks underlying differences between benign and malignant serous ovarian tumors?
Our analysis identified proteins with both novel and previously known associations to ovarian cancer biology. Despite the small overlap between differentially expressed protein sets in serum and tissue, APOA1 and Serotransferrin were significantly lower expressed in both serum and cancer tissue samples, suggesting a tissue-derived effect in serum. Pathway and subsequent interactome analysis also highlighted common regulators in serum and tissue samples, suggesting a yet unknown role for PCBP1 in ovarian cancer pathophysiology.
This study suggests that low-dose systemic tacrolimus has a preventive effect on laryngotracheal stenosis by inhibiting the activation of immune cells in the injured airway mucosa via the calcineurin/nuclear factor of activated T cell/interleukin 2 pathway.
