The clinical utility of Traditional Chinese Medicine (TCM) herbs/roots extracts in osteoporosis (OP) and osteoarthritis (OA) has been described in multiple reports, but there have been few studies of TCM for preventing bone loss and cartilage degradation simultaneously. Six-month-old female Sprague-Dawley rats each were subjected to ovariectomized (OVX) or sham surgery and treated orally once daily with herbal extracts or vehicle. Body weight was recorded weekly, and blood samples were collected from fasting animals at different time points...

We investigated the ability of microRNA-93 (miR-93) to influence proliferation, invasion, migration, and apoptosisofrenal cell carcinoma (RCC) cells via transforming growth factor-β/solvated metal atom dispersed (TGF-β/Smad) signaling by targeting runt-related transcription factor 3 (RUNX3). RCC tissues with corresponding adjacent normal tissues were collected from 249 RCC patients. And normal renal tissues were collected from patients without RCC who received nephrectomy. The RCC cell line ACHN was treated with miR-93 mimic, mimic-negative control (NC), miR-93 inhibitor, inhibitor-NC, and miR-93 inhibitor + small interfering RNA (siRNA) against RUNX3 (si-RUNX3)...

Cartilage tissue engineering provides a new method in the treatment of cartilage defects, and adipose derived stem cells seem to be an ideal seed cell in cartilage tissue engineering because of its characteristics. However, ossification after in vivo implantation of tissue engineered cartilage remains a challenge. Thrombospondin-1 which has been reported to have an inhibitory effect on angiogenesis, may play an important role in inhibiting the ossification of tissue engineered cartilage constructed by adipose derived stem cells...

H19 is involved in tumor metastasis and associated with tumor progression. Enhancer of zest homolog 2 (EZH2) is overexpressed in multiple cancer types and correlates with tumor proliferation, epithelial-mesenchymal transition, and poor prognosis. However, the interaction between H19 and EZH2 to promote tongue squamous cell carcinoma (TSCC) progression remains largely uncharacterized. Insitu hybridization and quantitative reverse-transcription PCR (qRT-PCR) were performed to measure H19 expression in primary TSCC and adjacent normal tissues and cell lines...

PURPOSE: Our goal was to derive more sensitive and accurate Z-scores based on combined DNA count- and size-based algorithms to advance molecular diagnostics for noninvasive prenatal testing of fetal trisomies. METHODS: We included 180 cases at high risk for fetal aneuploidy who underwent amniotic fluid cytogenetic analysis. We calculated their traditional count-based Z-scores, as well as their 100-, 130- and 150-, and 166-bp size-corrected Z-scores, and determined each Z-score's reliability based on its comparison to the cases' cytogenetic results...

Myelodysplastic syndrome (MDS) predominantly occurs in aging people. Over the past decades, the cellular and molecular pathologies of MDS cells have been intensively investigated. However, how the bone marrow stromal niches are altered during MDS development remains elusive. In this study, we attempted to isolate and characterize mesenchymal stromal cells (MSCs) from 30 MDS patients. We observed that only 9/30 bone marrow aspirations from MDS patients successfully formed a monolayer in vitro, while 17/17 bone marrow aspirations from normal donors (median age 45 years, range: 22-73 years) succeeded in this process...

Altered microRNA regulation has been implicated in the pathogenesis of various disorders, including cerebral ischemia/reperfusion injury (I/RI). However, the regulatory mechanism of miR-130b in cerebral ischemia injury has not been reported. In this study, we explored the role of miR-130b in cerebral ischemia injury and investigated its potential mechanism. Levels of miR-130b were quantified by real-time PCR, and the protein level of AQP4 was detected by Western blotting. Cell apoptosis was detected by flow cytometry...

MicroRNA-145 (miR-145) can regulate tumor cell invasion, metastasis, apoptosis, proliferation and stem cell differentiation. However, the molecular mechanisms of miR-145 used to regulate ovarian invasion and metastasis remain to be determined. In this study, Transwell cell migration and wound healing assays were used to detect the effects of miR-145 upregulation on ovarian carcinoma cell invasion and metastasis, respectively. The MUC1 expression vector, together with quantitative real-time PCR and Western blotting, was used to investigate the effects of miR-145 on E-cadherin (E-cad)-induced cell invasion and the related molecular mechanisms...

Injury and endothelial cell apoptosis are hall marks of atherosclerosis (AS). However, the mechanisms underlying its pathogenesis remain ill-defined. Recent evidence of a role for microRNAs in AS-associated endothelial cell apoptosis encouraged us to address this question. Here, AS was developed in ApoE (-/-) mice supplied with a high-fat diet (HFD), compared to ApoE (-/-) mice supplied with a normal diet (ND). Mouse endothelial cells were isolated from the aortic arch using flow cytometry based on their expression of CD31...

Activation of NADPH oxidase 2 (NOX2) triggers reactive oxygen species (ROS) generation, both of which are essential for robust microbial clearance by phagocytes. However, it is unknown whether inhibition of NOX2 activation or ROS generation affects cellular phagocytosis. Here, we found that the classic NOX2 inhibitor diphenyleneiodonium (DPI) induced uptake of E. coli by murine peritoneal macrophages through enhancing phagocytosis, and this effect was temperature-sensitive and attenuated by cytochalasin D as well as chemical inhibition of Syk and PLCγ, two downstream kinases involved in actin polymerization during phagocytosis...

Spinal cord ischemia and reperfusion (SCIR) injury is the major cause of a wide range of complications, including neural degeneration and devastating paraplegia. Decrease of inhibitory neurotransmitters and increase of excitory neurotransmitters are the major cause for the excitotoxicity of neurons. However, no study has reported the temporal loss of motor neuron in the ventral horn of spinal cord area following SCIR-induced spastic paralysis, not even the mechanism under it. In the present study, we found that the rabbits were mainly spastic paralyzed after spinal cord ischemia-reperfusion injury...

ASC amino acid transporter 2 (ASCT2), also known as solute linked carrier family 1 member A5 (SLC1A5) is a Na+-dependent glutamine/neutral amino acid transporter. ASCT2 acts as a high-affinity transporter of L-glutamine (Gln) and has been reported to be up-regulated in a variety of cancerous tissues including stomach, liver, and kidney. In this study, we evaluated anti-tumor efficacy of a novel anti-ASCT2 humanized monoclonal antibody, KM8094, which has a neutralizing activity against glutamine uptake, as a therapeutic antibody against gastric cancer and explored clinical predictive biomarker candidates by utilizing patient-derived xenograft (PDX) mouse models...

OBJECTIVE: Primary ovarian mucinous tumors progress from benign adenoma to borderline tumors to invasive mucinous carcinoma. A proper differential diagnosis is crucial to discriminate malignancies at the early stages of disease. However, few biomarkers are clinically available. We designed this study to analyze the clinical application of the oncogene IMP3 in monitoring early malignancies in ovarian primary mucinous tumors. METHODS: We collected 250 samples of ovarian primary mucinous tumors along with the corresponding clinicopathological information between 2009 and 2015 at the Gynecology and Obstetrics Hospital of Fudan University and performed immunochemical assays...

Doxorubicin (Dox) is an anthracycline antibiotic widely used in cancer treatment. Although its antitumor efficacy appears to be dose dependent, its clinical use is greatly restricted by development of cardiotoxicity. Sirtuin-3 (Sirt3) is the major deacetylase within the mitochondrial matrix that plays an important role in regulation of cardiac function. This study was performed to identify the regulatory role of Sirt3 on Dox-induced cardiac hypertrophy and mitochondrial dysfunction in rats in vivo and in vitro...

Opening of the mitochondrial permeability transition pore (mPTP) is considered central to reperfusion injury. Yet, most of our knowledge comes from observations in isolated mitochondria, cells, and organs. We used a rat model of ventricular fibrillation (VF) and closed-chest resuscitation to examine whether the mPTP opens in vivo and whether cyclosporine A (CsA) attenuates the associated myocardial injury. Two series of 26 and 18 rats each underwent 10 minutes of untreated VF before attempting resuscitation...

Glioblastoma multiforme is the most deadly primary brain tumor and has no effective treatment. Therefore, it is important to identify novel and effective therapies that impede glioma tumorigenesis. MicroRNAs (miRNAs) are helpful analytical biomarkers and may be useful targets for treating multiple human cancers. Previous reports suggest that miRNA-485-5p is dysregulated and contributes to tumorigenesis in some cancer types. Nevertheless, the biological role of miRNA-485-5p in glioma is not well understood. In this study, we demonstrated that miRNA-485-5p expression was reduced in gliomat issues and cell lines...

Long non-coding RNAs (lncRNAs) act critical roles in many biological processes, including cell proliferation, apoptosis, development, invasion and migration. LncRNA maternally expressed gene 3 (MEG3) is found to be downregulated in several tumors; however, its role in the atherosclerosis is still unknown. In the present study, we demonstrated that MEG3 expression level was downregulated in the coronary artery disease (CAD) tissues compared to in the control tissues. We also showed that TNF-α enhanced EC cell proliferation...
