We observed HLA associations in patients with nasopharyngeal carcinoma from northern China. There was an increased risk of nasopharyngeal carcinoma associated with HLA-B35 and a difference in the HLA association between patients with early- and late-onset disease. The frequency of B35 was significantly higher in patients than in control subjects, especially(More)
AIM To observe the effects of Ca2+ on hippocampal long-term potentiation (LTP) induced by nicotine in CA1 region of rat hippocampal slice. METHODS Extracellularly recorded population spikes (PS) of the pyramidal cell layer in the hippocampal CA1 region in vitro. RESULTS Nicotine 1 mumol.L-1 induced LTP in the hippocampal CA1 region. It did not induce(More)
AIM To investigate the relationship between activation of p42/44 mitogen-activated protein kinase (MAPK) pathway and hippocampal long term potentiation (LTP) induced by nicotine in area CA 1. METHODS Extracellular recording of population spike (PS) was performed within the pyramidal cell layer of hippocampal area CA1 in vitro; Western blot analysis was(More)
In this study, recursive random forests were used to build classification models for mouse liver toxicity. The mouse liver toxicity endpoint (67 toxic and 166 non-toxic) was a composition of four in vivo chronic systemic and carcinogenic toxicity endpoints (non-proliferative, neoplastic, proliferative and gross pathology). A multiple under-sampling approach(More)
We previously demonstrated that fermitin family member 1 (FERMT1) was significantly overexpressed in colon cancer (CC) and associated with poor metastasis-free survival. This study aimed to investigate the precise role of FERMT1 in CC metastasis and the mechanism by which FERMT1 is involved in the epithelial–mesenchymal transition (EMT). Correlations(More)
Endothelin-1 (ET-1) has been shown to be a potent growth factor and to induce cardiac hypertrophy. In the present study, we examined the role of G protein, protein kinase C (PKC) and Na(+)-H+ exchanger in ET-1-induced cardiac hypertrophy in cultured neonatal rat cardiac myocytes. ET-1 (10(-10)-10(-7) mol/L) induced promotion of 3H-leucine incorporation,(More)
OBJECTIVE To investigate the effect of miR-34b-3p on the proliferation, migration and tube formation of senescent endothelial cell. METHODS Primary human umbilical vein endothelial cells (HUVECs) were cultured in vitro, and population doubling levels (PDLs) were calculated by passage. The young endothelial cell was defined as PDL8. The senescent(More)
Leukemic-dendritic cells (leukemic-DCs) have certain limitations, which include difficult generation in 30-40% of patients, and low levels of expression of several key molecules. Therefore, an alternative approach using monocyte-derived DCs pulsed with tumor antigens is required. We investigated the possibility of immunotherapy for AML using(More)
To investigate the role of catecholamine and prostacyclin in ischemia reperfusion-induced ventricular fibrillation, experiments were performed in rat hearts using methods of radioimmunoassay and fluorohistochemistry. Regional myocardial ischemia was induced by ligation of the left coronary artery followed by reperfusion. In the ischemia reperfusion group,(More)
In this present study, the effects of ET-1 on intracellular free calcium concentration ([Ca2+]i) and the underlying mechanisms were investigated in cultured neonatal rat myocardial cells loaded with fura-2/AM. The results are as follows. ET-1 induced an increase of [Ca2+]i in a dose-dependent manner, which consisted of a transient and sustained phase.(More)
