Mechanically, salinomycin-induced cell growth inhibition against human glioma was mainly achieved by induction of G1-phase arrest via triggering reactive oxide species (ROS)-mediated DNA damage, as convinced by the activation of histone, p53, p21 and p27.
This study assessed whether CRM1, Ser10-phosphorylated p27, and p27 correlated with each other, with glioma pathological stage, and with patient outcome.
It was investigated whether there was a relationship between p53 p21 and p27 induction pathways in the cellular response of glioma cells to hyperthermia.Two glioma cell lines were employed.
Thus, disrupted regulation of p27 expression at high cell density may play an important role in determining the clinical behavior of human gliomas as well as the prognosis for glioma patients.
Neither baseline p27 levels nor p27 levels induced by confluency or serum deprivation correlate with p53 status or drug sensitivity of human glioma cell lines.
