There is now mounting evidence that the aryl hydrocarbon receptor (AhR) plays an important role in physiologic responses such as development, cell cycle regulation, immune function and also malignant transformation in various tissues. The strong nuclear AhR expression is observed in the invasive phenotype, and an elevated nuclear AhR expression is associated with a poor prognosis of human prostate cancer. On the other hand, there are conflicting results that the AhR deficiency results in increased susceptibility to prostate tumors in mouse model...

Aberrant expression of Liver X receptor α (LXRα) has been frequently reported in various types of cancers excluding gastric cancer (GC). Moreover, the role of LXRα in human GC has not been previously reported. In this study, we investigated the effect of LXRα down-regulation on invasion and EMT of GC. The expression of LXRα in GC cell lines was detected by real-time PCR. The LXRα siRNA was transiently transfected into GC cells using Lipofectamine™ 2000 reagent. Subsequently, cell invasive ability was evaluated by Transwell assays...

In a previous study, we reported that an identical defective provirus had integrated into multiple sites of the genome of a representative human T-lymphotropic virus type 1 (HTLV-1) cell line, MT-2. A possible explanation for this may be the repeated infection of this defective provirus to a cell. Therefore, we attempted to determine whether a defective provirus could transmit during the co-culture of HTLV-1 uninfected human T-cell line, Jurkat, with MT-2 cells treated with mitomycin C. As a result, we established not only a cell line with the integration of one complete provirus, but also a cell line with the integration of one defective provirus...

Mesenchymal stroma cells (MSCs) have potential as an emerging cell therapy for treating many different diseases, but discovery of the practical sources of MSCs is needed for the large-scale clinical application of this therapy. This study was to identify MSCs in peritoneal dialysis (PD) effluents that were discarded after PD. The effluents were collected from patients who were on the dialysis for less than 1 month. Adherent cells from the effluents were isolated by incubation in serum-containing medium in plastic culture dishes...

A new human uterine carcinosarcoma (UCS) cell line, TU-ECS-1, was established and characterized. The morphological appearance of the cultured cells was an insular of epithelial-like cells arranged in the form of a jigsaw puzzle and mesenchymal-like cells with a spindle-shaped or fibroblast-like morphology. A relatively high proliferation rate was observed with a doubling time of 18.2 h. The chromosome number ranged from 44 to 49 and had an extra chromosome 12 (trisomy 12). The respective half-maximal inhibitory concentrations of cisplatin, paclitaxel, and doxorubicin were 2...

Major facilitator superfamily domain containing 2a (Mfsd2a) is a member of the major facilitator superfamily. Mfsd2a functions as a transporter for docosahexaenoic acid and also plays a role in the unfolded protein response (UPR) upon tunicamycin (TM) exposure. UPR is involved in the pathogenesis of various human diseases. TM and thapsigargin are representative experimental reagents that induce UPR. To elucidate the detailed function of Mfsd2a in UPR in vivo, we generated Mfsd2a-deficient mice and investigated the role of Mfsd2a during UPR induced by TM or thapsigargin...

Motion sickness medications such as Travelmin(®) prescribed in Japan include diphenhydramine (DPH), dyphylline, diphenidol, and/or caffeine. Herein, we report a patient who died due to rhabdomyolysis after ingesting a DPH containing motion sickness medication. A Japanese male in his 30 s reported missing after going out for a drive early in the morning was found dead in his car in the evening of the same day. An autopsy showed moderate edema, congestion, and several petechiae in both lungs. The brain was congested and edematous with no atherosclerosis of cerebral arteries...

The aim of the present study is to investigate protective effects of hydrogen-rich water (HW) against reactive oxygen species (ROS)-induced cellular harmful events and cell death in human gingival fibroblasts (HGF) and three-dimensional (3D-) gingival tissue equivalents. HW was prepared with a magnesium stick in 600-mL double distilled water (DDW) overnight. Dissolved hydrogen was about 1460 ± 50 μg/L versus approximately 1600 μg/L for the saturated hydrogen. Under cell-free conditions, HW, dose-dependently, significantly scavenged peroxyl radicals (ROO·) derived from 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH)...

Small cell lung cancer (SCLC) is one of the most malignant neoplasms in common human cancers. The tumor is composed of small immature-looking cells with a round or fusiform shape, which possesses weak adhesion features among them, suggesting that SCLC shows the morphological characteristics of epithelial to mesenchymal transition (EMT). SCLC is characterized by high metastatic and recurrent rates, sensitivity to the initial chemotherapy, and easy acquirement of chemoresistance afterwards. These characters may be related to the EMT phenotype of SCLC...

Lung cancer is the most common solid tumor and the leading cause of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) represents the major histological subtype and accounts for about 80 % cases of lung cancer cases. Recently, lncRNA lncTCF7 was identified, which is highly expressed in hepatocellular carcinoma (HCC) tumors and liver cancer stem cells (CSCs). However, the role of lnTCF7 in NSCLC remains largely unknown. In this study, Gain- and loss-of-function studies demonstrated the critical role of lncTCF7 in promoting invasion and self-renewal in NSCLC cells...

Increasing evidence has confirmed that the dysregulation of microRNAs (miRNAs) contributes to the proliferation and invasion of human cancers. Previous studies have shown that the dysregulation of miR-124 is in numerous cancers. However, the roles of miR-124 in human osteosarcoma (OS) have not been well clarified. Therefore, this study was to investigate the biological functions and molecular mechanisms of miR-124 in OS cell lines, discussing whether it could be a therapeutic biomarker of OS in the future. In this study, our results demonstrated that miR-124 was down-regulated in OS cell lines and tissues...

Ewing's sarcoma/primitive neuroectodermal tumor/Askin's tumor (Ewing`s sarcoma family of tumors: ESFT) is the most common type of malignant tumor of bone and soft tissue in children and young adults, and morphologically is a member of a group of small round cell tumors. We report, here, on the establishment of two human ESFT cell lines, FU-PNET-3 and FU-PNET-4, from the iliac and the chest wall, respectively, the cells of both cell lines were tumorigenic in immunodeficient mice. Histologically, both original and xenograft tumors and cultured cells were composed of small round cells with positive immunoreactivity for CD99 and Nkx2...

The ability to generate neural progenitor cells from human umbilical cord mesenchymal stem cells (hUC-MSCs) has provided an option to treat neurodegenerative diseases. To establish a method for this purpose, we characterized the early neural markers of hUC-MSCs-derived cells under different conditions. We found that neither the elimination of signals for alternative fate nor N2 supplement was sufficient to differentiate hUC-MSCs into neural precursor cells, but the GSK3 inhibitor SB216763 could promote an efficient neural commitment of hUC-MSCs...

Previous reports have mainly focused on the behavioral responses of human periodontal ligament stem cells (hPDLSCs) in interaction with tibia bone marrow stromal cells (BMSCs). However, there is little study on the biologic features of hPDLSCs under the induction of maxilla BMSCs (M-BMSCs) at different phases of osteogenic differentiation. We hypothesized that M-BMSCs undergoing osteogenic differentiation acted on the proliferation, differentiation, and bone-forming capacity of hPDLSCs. In this paper, primary hPDLSCs and human M-BMSCs (hM-BMSCs) were expanded in vitro...

Chronic kidney disease (CKD) disrupts mineral homeostasis and its representative pathosis is defined as secondary hyperparathyroidism (SHPT). SHPT occurs during the early course of progressive renal insufficiency, and is associated with mortality and cardiovascular events. SHPT results in reduction of calcium-sensing receptor (CaSR) and vitamin D receptor (VDR) in the parathyroid glands during CKD. However, the precise mechanism of CaSR and VDR reduction is largely unknown. CKD was induced through two-step 5/6 nephrectomy, and then CKD rats and sham-operated rats were maintained for 8 weeks on diets containing 0...

A cell line, designated NOCC, was established from the ascites of a patient with clear cell adenocarcinoma of the ovary. The cell line has been grown without interruption and continuously propagated by serial passaging (more than 76 times) over 7 years. The cells are spherical to polygonal-shaped, display neoplastic, and pleomorphic features, and grow in a jigsaw puzzle-like pattern while forming monolayers without contact inhibition. The cells proliferate rapidly, but are easily floated as a cell sheet. The population doubling time is about 29 h...

Trophectoderm vesicles (TVs) are observed in some blastocysts that penetrate cells from the zona pellucida to the outer margin. Therefore, we compared this incidence in relation to hatching, pregnancy, and miscarriage rates between conventional in vitro fertilization (c-IVF) and intracytoplasmic sperm injection (ICSI). Vitrified/warmed blastocysts (n = 112) were derived from surplus embryos. The blastocysts were then observed using time-lapse cinematography to resolve the relationship between hatching and implantation...

Hepatocellular carcinoma (HCC) is one of the most common human cancers all over the world. Increasing evidences have demonstrated that long noncoding RNAs (lncRNAs) play important roles in malignant transformation, tumor growth and metastasis in HCC. Among lncRNAs, ultraconserved RNAs (ucRNAs) containing an ultraconserved region have been report to contribute to human cancers. lncRNA ultraconserved element 338 (uc.338) was first found to be upregulated in HCC and promote cell growth. However, the exact mechanism by which uc...

Diabetes mellitus is an endocrine and metabolic disease characterized by high blood glucose. Diabetic nephropathy (DN) is one of the most typical diabetic complications. Cornus officinalis is a type of traditional Chinese medicine that replenishes the liver and kidney. Morroniside is one of the main characteristic components of C. officinalis. In this study, an in vitro model for simulating DN damage was established by stimulating rat glomerular mesangial cells by the advanced glycation end products. The protective mechanism and effect of morroniside in regulating receptor for advanced glycation end products signaling pathway in DN was investigated to provide experimental evidence for the prevention and treatment of DN...
