Choroidal melanoma is the most common primary intraocular tumor in adults. Cepharanthine (CEP), a natural alkaloid extracted from the roots of Stephania cepharantha Hayata, has been demonstrated to inhibit the proliferation of various cancer cells. However, its potential anticancer effect in choroidal melanoma has not been clarified yet. In the present study, it was identified that CEP may potently inhibit the proliferation of human choroidal melanoma cells, induce cell death and cell cycle arrest, and activate cellular apoptotic proteins, including Bcl-2-associated X protein, caspase and poly(ADP-ribose) polymerase...

BACKGROUND: Sepsis is one of the main causes of mortality in critically ill patients following progression to septic shock. To investigate the pathophysiologic changes of sepsis, we developed a novel porcine model of septic shock induced by acute respiratory distress syndrome (ARDS) due to methicillin-resistant Staphylococcus aureus(MRSA) pneumonia. METHODS: Twenty-six male Landraces (Lvyuanweiye, Beijing, China) weighing 30 ± 2 kg were divided into four groups: sham group (SH; n = 5); cotton smoke inhalation group (SM; n = 6); MRSA pneumonia group (MR; n = 6); and septic shock group with cotton smoke inhalation + MRSA pneumonia (SS; n = 9)...

Bladder cancer is one of the leading causes of cancer-related death in men, however, there was only limited effective treatment for invasive bladder cancer. DAPK1 has been shown to play important role in apoptosis and autophagy to suppress cancer progression. Previous results have shown that DAPK1 promoter was hypermethylated in the majority of bladder cancer specimens, however, the prognostic significance of DAPK1 in bladder cancer has yet to be demonstrated. In the present study, we found that DAPK1 expression was negatively associated with tumor stage and a low level expression of DAPK1 in bladder cancer specimens were associated with shorter survival in bladder cancer patients in 3 independent bladder cancer datasets (n = 462)...

BACKGROUND: Lung cancer is the most frequently diagnosed cancer and the leading cause of cancer-related deaths worldwide. Up to 80% of cancer patients are classified as non-small-cell lung cancer (NSCLC) and cisplatin remains as the gold standard chemotherapy treatment, despite its limited efficacy due to both intrinsic and acquired resistance. The CK2 is a Ser/Thr kinase overexpressed in various types of cancer, including lung cancer. CIGB-300 is an antitumor peptide with a novel mechanism of action, since it binds to CK2 substrates thus preventing the enzyme activity...

BACKGROUND: Renal dysfunction, commonly associated with cardiac dysfunction, has predictive value for adverse long-term outcomes in heart failure (HF). We previously identified a novel renal biomarker, interleukin-34 (IL-34), elevated in HF patients and associated with kidney dysfunction and coronary artery disease during HF. However, the prognostic value of IL-34 in HF remains unclear, so that the present study aimed to determine it. METHODS AND RESULTS: This prospective, observational study included 510 consecutive HF patients with their serum IL-34 as well as other variables measured at baseline, and they were followed up for 2 years...

BACKGROUND: T-cell death-associated gene 8 (TDAG8), a member of the proton-sensitive G-protein-coupled receptor (GPCR) class with an immune-specific expression profile, was recently shown to be expressed in the rat brain; however, its role in ischaemic stroke remains unknown. METHODS: We initially confirmed the time-dependent expression of TDAG8 in rat brain tissue after ischaemic stroke and reperfusion. Further evaluations were performed to increase TDAG8 expression 6h prior to middle cerebral artery occlusion (MCAO) by injecting a specific agonist, BTB09089, into the lateral ventricle to increase TDAG8 expression...

BACKGROUND/AIMS: The epidermal growth factor receptor-tyrosine kinase inhibitor gefitinib is effective against several malignancies and is mainly utilized in the treatment of epidermal growth factor receptor mutation positive non-small cell lung cancer. The anti-cancer effect of the drug involves stimulation of apoptosis. Side effects of gefitinib include anemia. At least in theory, the development of anemia during gefitinib treatment could result from triggering of eryptosis, the suicidal erythrocyte death characterized by cell shrinkage and by cell membrane scrambling with phosphatidylserine translocation to the erythrocyte surface...
