PRR11 Is a Prognostic Marker and Potential Oncogene in Patients with Gastric Cancer Zongchang Song Wenying Liu Yu Xiao Minghui Zhang Yan Luo 1 Weiwei Yuan Yu Xu Guanzhen Yu Yide Hu 10.1371/journal.pone.0128943 https://plos.figshare.com/articles/dataset/_PRR11_Is_a_Prognostic_Marker_and_Potential_Oncogene_in_Patients_with_Gastric_Cancer_/1506171 <div><p>PRR11 is a potential candidate oncogene that has been implicated in the pathogenesis of lung cancer, however the role of PRR11 in gastric cancer is currently unclear. In the present study, we investigated the role of PRR11 in gastric cancer by evaluating its expression status in samples from a cohort of 216 patients with gastric cancer. PRR11 was found to be overexpressed in 107 (49.5%) patients by immunohistochemistry of tissue microarrays generated using the patient samples. Furthermore, PRR11 overexpression was found to correlate significantly with clinicopathologic features such as tumor invasion, tumor differentiation, and disease stage. Survival analysis of the cohort revealed that PRR11 is an independent prognostic factor for gastric cancer patients. PRR11 was stably silenced in a gastric carcinoma cell line using an shRNA-based approach, and treated cells showed decreased cellular proliferation and colony formation in vitro and cell growth in vivo, companied by decreased expression of CTHRC1 and increased expression of LXN, proteins involved in tumor progression. Evaluation of human gastric cancer samples demonstrated that PRR11 expression was also associated with increased CTHRC1 and decreased LXN expression. These data indicate that PRR11 may be widely activated in human gastric cancer and are consistent with the hypothesis that PRR11 functions as an oncogene in the development and progression of gastric cancer.</p></div> 2015-08-07 04:01:03 PRR 11 expression LXN CTHRC 1 carcinoma cell line Gastric Cancer PRR 11 PRR 11 functions PRR 11 PRR 11 overexpression
