The action mechanism of lncRNA-HOTAIR on the drug resistance of non-small cell lung cancer by regulating Wnt signaling pathway.
Authors: Guo F, Cao Z, Guo H, Li S Abstract The action mechanism of long non-coding ribonucleic acid-homeobox transcript antisense ribonucleic acid (lncRNA-HOTAIR) in the regulation of the Wnt signaling pathway on the drug resistance of non-small cell lung cancer was investigated. Forty eight patients with non-small cell lung cancer, who were treated with cisplatin (DDP) as neoadjuvant chemotherapy, were selected from the specimen bank of the Department of Pathology of Peking Union Medical College Hospital. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the messenger RNA (mRNA) level of...

Abstract 1214: TP53 affects SOX2 copy number alterations and expression in non-small cell lung cancer
Background: Amplifications of the transcription factor, SRY (sex determining region Y)-box 2 (SOX2), are common in non-small cell lung cancer (NSCLC). SOX2-signaling is important in maintaining the stem cell-like phenotype of cancer cells and contributes to the pathogenesis of lung cancer. TP53 is recognized as a critical regulator of stem cell pluripotency, and it is known that TP53 represses many stem cell associated genes following DNA damage. We hypothesized that SOX2 copy number alterations in lung tumors could be correlated to mutational status of TP53 gene in tumors and that TP53 played a role in regulation of SOX2 ...
