Fig. 4From: Ku80 correlates with neoadjuvant chemotherapy resistance in human lung adenocarcinoma, but reduces cisplatin/pemetrexed-induced apoptosis in A549 cellsKu80 protein and mRNA expression in lung cancer of the response and nonresponse groups. Ku80 protein expression in lung cancer of the response (a) and nonresponse groups (b) obtained by fiberoptic bronchoscopy. c Immunohistochemical scores of Ku80 were calculated in response group (n = 38) and nonresponse group (n = 72). Ku80 expression level of the response group was reduced compared to the nonresponse group (2.079 ± 1.617, 5.597 ± 2.114). d Quantitative RT-PCR analysis showed Ku80 mRNA expression between response (3.612 ± 2.392) and nonresponse (7.981 ± 2.684) groups. Data were shown as the mean ± SD. *p < 0.05Back to article page
