BACKGROUND/AIMS: The anaplastic lymphoma kinase (ALK) inhibitor ASP3026 is in clinical development for the treatment of ALK expressing non-small cell lung carcinoma (NSCLC). ASP3026 is in part effective by inducing apoptosis of tumor cells. Erythrocytes lack mitochondria and nuclei, key organelles in the execution of apoptosis, but are nevertheless able to enter suicidal death or eryptosis, which is characterized by cell membrane scrambling with phosphatidylserine translocation to the cell surface and by cell shrinkage...

Liver cancer is the second most common cause of cancer-related death. The major forms of primary liver cancer are hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA). Both these tumors develop against a background of cirrhotic liver, non-alcoholic fatty liver disease, chronic liver damage and fibrosis. HCC is a heterogeneous disease which usually develops within liver cirrhosis related to various etiologies: hepatitis B virus (HBV) infection (frequent in Asia and Africa), hepatitis C virus (HCV), chronic alcohol abuse, or metabolic syndrome (frequent in Western countries)...

Long non-coding RNAs (lncRNAs) serve an important role in numerous human diseases, including cancer. Abnormal expression of lncRNAs has been associated with a number of tumor types; however, the underlying mechanisms through which lncRNA functions have yet to be elucidated. The present study primarily focuses on insulin-like growth factor 2 antisense 1 (Igf2as), a lncRNA reported to be differentially expressed in hepatocellular carcinoma (HCC). Reverse transcription-quantitative polymerase chain reaction analysis was used to determine the level of Igf2as in HCC cells and tissues...

Lung squamous cell carcinoma (SCC) is the second most common subtype of non-small cell lung carcinoma. The anticancer effects of arsenic trioxide (ATO) in lung adenocarcinoma and small-cell lung cancer have previously been reported; however its effects in SCC remain unclear. An MTT assay and western blot analysis were performed to determine cell viability and protein expression, respectively, in the SK-MES-1 and SW900 SCC cell lines following treatment with ATO. Phosphatidylserine externalization, mitochondrial membrane depolarization and cell cycle distribution were studied using flow cytometry and the in vivo effects of ATO on tumour growth were investigated with a xenograft model...

Rebiopsy is considered an option for specific types of cancer, such as breast, non-small cell lung, and prostate cancer, in clinical trials and in practice. The benefit of rebiopsy comes from the selection of a new treatment strategy based on the genetic profile of the cells, which may reflect the development of drug resistance or hormonal changes. For colorectal cancer, the presence of different genomic mutations between the primary tumor and its metastases is rare, and rebiopsy is therefore not generally performed...

Non-small cell lung cancer (NSCLC) patients with squamous cell carcinoma (SCC) histology have limited chemotherapeutic options. Treatment with S-1 combined with carboplatin (CBDCA) has been shown to provide a significant survival benefit in SCC patients compared with treatment with combined CBDCA and paclitaxel. The aim of the present study was to investigate the association between the expression of molecular markers related to the pharmacological action of S-1, including thymidylate synthase (TS), orotate phosphoribosyltransferase (OPRT) and dihydropyrimidine dehydrogenase (DPD), and the clinical efficacy of S-1-based chemotherapy in SCC patients...

Lung squamous cell carcinoma (SCC), accounting for approximately 30% of non-small cell lung cancer, is often refractory to therapy. Screening a small molecule library, we identified digitoxin as a high potency compound for suppressing human lung SCC growth in vitro and in vivo. Mechanistic investigations revealed that digitoxin attenuated YAP phosphorylation and promoted YAP nuclear sequestration. YAP activation led to excessive accumulation of reactive oxygen species (ROS) by downregulating the antioxidant enzyme GPX2 in a manner related to p63 blockade...
