hnRNPA2B1 represses the disassembly of arsenite-induced stress granules and is essential for male fertility.

Although the composition and assembly of stress granules (SGs) are well understood, the molecular mechanisms underlying SG disassembly remain unclear. Here, we identify that heterogeneous nuclear ribonucleoprotein A2/B1 (hnRNPA2B1) is associated with SGs and that its absence specifically enhances the disassembly of arsenite-induced SGs depending on the ubiquitination-proteasome system but not the autophagy pathway. hnRNPA2B1 interacts with many core SG proteins, including G3BP1, G3BP2, USP10, and Caprin-1; USP10 can deubiquitinate G3BP1; and hnRNPA2B1 depletion attenuates the G3BP1-USP10/Caprin-1 interaction but elevates the G3BP1 ubiquitination level under arsenite treatment.

Alterations in volumes and MRI features of amygdala in Chinese autistic preschoolers associated with social and behavioral deficits.

To examine the amygdala volume in 2-5-year-old preschool children with autism and explore the relationship between amygdala volumes based on MRI findings and clinical features. A total of 39 cases with clinically diagnosed autism were collected. The oblique coronal T1 weighted image (T1WI) sequence was used to measure the volume of amygdala and the MRI signals were measured and analyzed.

Regulatory crosstalk between KLF5, miR-29a and Fbw7/CDC4 cooperatively promotes atherosclerotic development.

Atherogenesis is a chronic inflammatory process that involves complex interactions between endothelial dysfunction, lipid deposition and vascular smooth-muscle cell (VSMC) proliferation. However, the molecular mechanism is still unclear. We found that a pro-atherosclerotic factor (oxLDL) induced the expression of Krüppel-like factor 5 (KLF5), which in turn increased miR-29a expression levels.

Targeted Therapy of Ovarian Cancer with Angiogenesis Inhibitors.

Specific blocking of interactions between ligands and receptors along the angiogenic pathways represents an effective approach for enhancing the efficacy as well as reducing adverse effects of chemotherapy. Over the past decade, there was a rapid progression in the application of this therapeutic strategy in cancer treatment. Anti-angiogenic therapy is the most promising targeted therapy for ovarian cancer.

Dysregulation of LncRNAs in Placenta and Pathogenesis of Preeclampsia.

Background: Preeclampsia, a gestational disease characterized by hypertension and proteinuria twenty weeks into pregnancy, is one of the leading causes of fetal and maternal mortality. Although multiple genetic and environmental factors are found to be related to the preeclampsia risk, the pathogenic pathways remain largely undefined. The placenta plays a critical role in the fetal development by carrying out the barrier, fetal-maternal exchange, and endocrine functions during pregnancy.

Long noncoding RNAs (LncRNAs) - The dawning of a new treatment for cardiac hypertrophy and heart failure.

Long noncoding RNAs (lncRNAs) represent a category of noncoding RNAs with the potential for genetic and epigenetic regulations. As important regulators of gene expression, increasing evidence has proven that lncRNAs play a significant regulatory role in various cardiovascular pathologies. In particular, lncRNAs have been proved to be participating in gene regulatory mechanisms involved in heart growth and development that can be exploited to repair the injured adult heart.

HE4-test of urine and body fluids for diagnosis of gynecologic cancer.

Serum epididymis protein 4 (HE4) level is a useful biomarker for the management of ovarian and endometrial cancer patients. Urine HE4-test, with its easier access than serum test, has emerged as a new method with promising application for the diagnosis of ovarian cancer. Areas covered: This review summarizes data regarding the detection and alteration of HE4 in urine samples collected from ovarian cancer patients and controls.

MRI/optical dual-modality imaging of vulnerable atherosclerotic plaque with an osteopontin-targeted probe based on FeO nanoparticles.

Rupture of vulnerable atherosclerotic plaque is the major pathological cause of luminal thrombosis in acute coronary syndromes. Since foamy macrophages have been identified as a prominent component in vulnerable atherosclerotic lesions and osteopontin (OPN) is reported to be highly expressed in foamy macrophages, OPN could be a potential target for vulnerable atherosclerotic plaque imaging. The current study designed an OPN-specific MRI/optical dual-modality probe to detect vulnerable plaques.

Submillisievert coronary CT angiography with adaptive prospective ECG-triggered sequence acquisition and iterative reconstruction in patients with high heart rate on the dual-source CT.

Purpose: To assess the application value of submillisievert coronary CT angiography (CCTA) in patients with a high heart rate (HR) acquired with adaptive prospective ECG-triggered sequence acquisition and iterative reconstruction on the secondary generation dual-source CT.

Materials And Methods: A total of 120 consecutive high-HR patients suspected with coronary artery disease underwent CCTA and invasive coronary angiography (ICA) within two weeks. Patients were randomly assigned into three groups: group A (n = 40), where the patients underwent retrospectively ECG-triggered acquisition CCTA at 100 kVp; group B (n = 40), where the patients received adaptive prospective ECG-triggered sequence acquisition at 100 kVp; and group C (n = 40), where the patients performed adaptive prospective ECG-triggered sequence acquisition at 80 kVp with iterative reconstruction.

Advances of Molecular Imaging for Monitoring the Anatomical and Functional Architecture of the Olfactory System.

The olfactory system of organisms serves as a genetically and anatomically model for studying how sensory input can be translated into behavior output. Some neurologic diseases are considered to be related to olfactory disturbance, especially Alzheimer's disease, Parkinson's disease, multiple sclerosis, and so forth. However, it is still unclear how the olfactory system affects disease generation processes and olfaction delivery processes.

Hepatitis C therapy with interferon-α and ribavirin reduces the CD4 cell count and the total, 2LTR circular and integrated HIV-1 DNA in HIV/HCV co-infected patients.

This study investigated whether treatment with IFN-α and ribavirin (RBV) reduces 2LTR circular HIV DNA in addition to the total and integrated HIV DNA. Two groups of patients were enrolled. Group 1 comprised HIV/HCV co-infected patients who were treated with highly active antiretroviral therapy (HAART), IFN-α and RBV for 48 weeks.

Structural gray matter change early in male patients with HIV.

The purpose of this study is to characterize brain gray matter volumetric changes in HIV seropositive without neurocognitive impairment and seronegative men in Asia. We investigate 36 males with HIV seropositive (mean age 34.5±9.

A novel stent coated with antibodies to endoglin inhibits neointimal formation of porcine coronary arteries.

Endoglin/CD105 is an accessory protein of the transforming growth factor-β receptor system that plays a critical role in proliferation of endothelial cells and neovasculature. Here, we aimed to assess the effect of novel stents coated with antibodies to endoglin (ENDs) on coronary neointima formation. Thirty ENDs, thirty sirolimus-eluting stents (SESs), and thirty bare metal stents (BMSs) were randomly assigned and placed in the coronary arteries in 30 juvenile pigs.

In vitro and in vivo evaluation of a humanized anti-APRIL antibody.

A proliferation-inducing ligand (APRIL) is overexpressed in many cancers such as colorectal, gastric and liver. Silence APRIL gene or neutralize its expression may serve as therapeutic strategies to manage those cancers. Current phase I clinical trial shows that heavily pretreated patients were well tolerated high dose intravenous infusion.
