MASP1 and central nervous system cancer: Notably, MASP1 and MASP3 are highly expressed in the C6 and T98G glioma cell lines (Kuraya et al., 2003; Pagliara et al., 2018), but their expression is low in some ovarian cancer patients and the MASP1 and MASP3 expression levels are positively correlated with patient prognosis (Swierzko et al., 2007).
