CRM1 inhibitor S109 suppresses cell proliferation and induces cell cycle arrest in renal cancer cells.

Abnormal localization of tumor suppressor proteins is a common feature of renal cancer. Nuclear export of these tumor suppressor proteins is mediated by chromosome region maintenance-1 (CRM1). Here, we investigated the antitumor eff ects of a novel reversible inhibitor of CRM1 on renal cancer cells.

Hydroxymethylation of microRNA-365-3p Regulates Nociceptive Behaviors via Kcnh2.

Unlabelled: DNA 5-hydroxylmethylcytosine (5hmC) catalyzed by ten-eleven translocation methylcytosine dioxygenase (TET) occurs abundantly in neurons of mammals. However, the in vivo causal link between TET dysregulation and nociceptive modulation has not been established. Here, we found that spinal TET1 and TET3 were significantly increased in the model of formalin-induced acute inflammatory pain, which was accompanied with the augment of genome-wide 5hmC content in spinal cord.

Background: The aim of this study was to assess the effect of low-dose adenosine on hepatic artery flow (HAF) when administered intraoperatively by continuous infusion.

Materials And Methods: Between January 2009 and August 2009, 74 patients underwent orthotopic liver transplantation (OLT). Ten patients were enrolled for adenosine treatment, and 64 non-study patients served as controls.

Plasma Homocysteine and Prognosis of Acute Ischemic Stroke: a Gender-Specific Analysis From CATIS Randomized Clinical Trial.

Elevated total homocysteine level (tHcy) has been hypothesized to be associated with morbidity and mortality of stroke; however, results regarding the association between plasma tHcy status and prognosis of acute ischemic stroke are inconsistent. Moreover, the gender effect on this association has yet to be explored. We thus prospectively investigated whether higher tHcy concentrations predicted poor stroke prognosis in Chinese adults.

Comparison of Long-Term Outcomes of Endovascular Management for Membranous and Segmental Inferior Vena Cava Obstruction in Patients With Primary Budd-Chiari Syndrome.

Background: Endovascular management is important for the treatment of primary Budd-Chiari syndrome, which is caused by inferior vena cava (IVC) obstruction. The aims of this study were to compare long-term outcomes of endovascular management for primary Budd-Chiari syndrome patients with membranous obstruction of IVC (MOVC) and segmental obstruction of IVC (SOVC) and explore the optimal endovascular strategy for these conditions.

Methods And Results: Clinical data of 265 patients with Budd-Chiari syndrome who received endovascular management (MOVC group, n=136; SOVC group, n = 129) were retrospectively reviewed.

Hemodynamics of left internal mammary artery bypass graft: Effect of anastomotic geometry, coronary artery stenosis, and postoperative time.

Although the left internal mammary artery (LIMA) bypass graft is the best choice for surgical revascularization, its hemodynamics are still complex and can result in long-term graft failure. Here, we performed a hemodynamic analysis of the LIMA-coronary artery with end-to-side/side-to-side anastomoses based on 15 patient-specific CTA images at various postoperative periods. We hypothesize that hemodynamic patterns are determined by the interplay of LIMA geometry, anastomotic configuration, and severity of native coronary artery stenosis, which are strongly affected by the postoperative time.

Codelivery of Doxorubicin and shAkt1 by Poly(ethylenimine)-Glycyrrhetinic Acid Nanoparticles To Induce Autophagy-Mediated Liver Cancer Combination Therapy.

Combination therapy has been developed as a promising therapeutic approach for hepatocellular carcinoma therapy. Here we report a low toxicity and high performance nanoparticle system that was self-assembled from a poly(ethylenimine)-glycyrrhetinic acid (PEI-GA) amphiphilic copolymer as a versatile gene/drug dual delivery nanoplatform. PEI-GA was synthesized by chemical conjugation of hydrophobic GA moieties to the hydrophilic PEI backbone via an acylation reaction.

Association of the interleukin-18 receptor 1 and interleukin-18 receptor accessory protein polymorphisms with the risk of esophageal cancer.

Esophageal cancer is the fourth leading cause of cancer-associated fatalities and the fourth most commonly diagnosed cancer. In addition to environmental risk factors, genetic factors may have a significant role in esophageal cancer carcinogenesis. A hospital-based case-control study was conducted to evaluate the genetic effects of functional single-nucleotide polymorphisms in the interleukin-18 (), IL-18 receptor 1 protein (), IL-18 receptor accessory protein () and on the development of esophageal cancer.

A total of 108 NSCLC patients (stages I-IIIA) were treated with a standard chemotherapy regimen of cisplatin plus vinorelbine. Additionally, cultured A549 cells were treated with cisplatin in the presence or absence of tunicamycin.

Early atherosclerosis aggravates renal microvascular loss and fibrosis in swine renal artery stenosis.

Renal function in patients with atherosclerosis and renal artery stenosis (ARAS) deteriorates more frequently than in nonatherosclerotic RAS. We hypothesized that ARAS aggravates stenotic-kidney micro vascular loss compared to RAS. Domestic pigs were randomized to normal, RAS, and ARAS (RAS fed a high-cholesterol diet) groups (n = 7 each).

Salvianolic Acid A Attenuates Cell Apoptosis, Oxidative Stress, Akt and NF-κB Activation in Angiotensin-II Induced Murine Peritoneal Macrophages.

We discuss the role of Salvianolic acid A(SAA), one of the main effective components in Salvia Miltiorrhiza (known as 'Danshen' in traditional Chinese medicine), in apoptotic factors, the production of oxidative products, and the expression of Akt and NF-κB in angiotensin II (Ang II)-mediated murine macrophages. In the present study, Ang II was added to mice abdominal macrophages with or without addition of SAA. After cell identification, apoptosis was measured by DNA strand break level with TdT-mediated dUTP nick-end labeling (TUNEL) staining, and the expression of Bcl-2 and Bax.

SOS response and its regulation on the fluoroquinolone resistance.

Bacteria can survive fluoroquinolone antibiotics (FQs) treatment by becoming resistant through a genetic change-mutation or gene acquisition. The SOS response is widespread among bacteria and exhibits considerable variation in its composition and regulation, which is repressed by LexA protein and derepressed by RecA protein. Here, we take a comprehensive review of the SOS gene network and its regulation on the fluoroquinolone resistance.

Long non-coding RNAs expression profiles in hepatocytes of mice after hematopoietic stem cell transplantation.

Hepatic veno-occlusive disease (HVOD), one serious complication following hematopoietic stem cell transplantation (HSCT), is mainly initiated by the damage to sinusoidal endothelial cells and hepatocytes. Long non-coding RNAs (lncRNAs) play an important role in the proliferation of hepatocytes and liver regeneration. lncRNAs profile in hepatocytes post-HSCT remains unclear.

Ischemic preconditioning protects the brain against injury via inhibiting CaMKII-nNOS signaling pathway.

Although studies have shown that cerebral ischemic preconditioning (IPC) can ameliorate ischemia/reperfusion (I/R) induced brain damage, but its precise mechanisms remain unknown. Therefore, the aim of this study was to investigate the neuroprotective mechanisms of IPC against ischemic brain damage induced by cerebral I/R and to explore whether the Calcium/calmodulin-dependent protein kinase II (CaMKII)-mediated up-regulation of nNOS ser847-phosphorylation signaling pathway contributed to the protection provided by IPC. Transient global brain ischemia was induced by 4-vessel occlusion in adult male Sprague-Dawley rats.
