Eutopic/ectopic endometrial apoptosis initiated by bilateral uterine artery occlusion: A new therapeutic mechanism for uterus-sparing surgery in adenomyosis

The objective of the present study was to investigate differences in the expression of apoptosis-related factors in the eutopic and ectopic endometrium (EuE/EE) in women with adenomyosis before and after laparoscopic bilateral uterine artery occlusion (LUAO). Ten patients with uterine adenomyosis who received LUAO were selected as the research subjects, from whom EuE and EE...

TGF-β1 Reduces miR-29a Expression to Promote Tumorigenicity and Metastasis of Cholangiocarcinoma by Targeting HDAC4

Transforming growth factor β1 (TGF-β1) and miRNAs play important roles in cholangiocarcinoma progression. In this study, miR-29a level was found significantly decreased in both cholangiocarcinoma tissues and tumor cell lines. TGF-β1 reduced miR-29a expression in tumor cell lines. Furthermore, anti-miR-29a reduced the proliferation and metastasis capacity of cholangiocarcinoma...

Synergistic Induction of Potential Warburg Effect in Zebrafish Hepatocellular Carcinoma by Co-Transgenic Expression of Myc and xmrk Oncogenes

Previously we have generated inducible liver tumor models by transgenic expression of Myc or xmrk (activated EGFR homolog) oncogenes in zebrafish. To investigate the interaction of the two oncogenes, we crossed the two transgenic lines and observed more severe and faster hepatocarcinogenesis in Myc/xmrk double transgenic zebrafish than either single transgenic fish. RNA-Seq...

Metabolomic Characterizations of Liver Injury Caused by Acute Arsenic Toxicity in Zebrafish

Arsenic is one of the most common metalloid contaminants in groundwater and it has both acute and chronic toxicity affecting multiple organs. Details of the mechanism of arsenic toxicity are still lacking and profile studies at metabolic level are very limited. Using gas chromatography coupled with mass spectroscopy (GC/MS), we first generated metabolomic profiles from the livers...

High Glucose Induces Podocyte Injury via Enhanced (Pro)renin Receptor-Wnt-β-Catenin-Snail Signaling Pathway

(Pro)renin receptor (PRR) expression is upregulated in diabetes. We hypothesized that PRR contributes to podocyte injury via activation of Wnt-β-catenin-snail signaling pathway. Mouse podocytes were cultured in normal (5 mM) or high (25 mM) D-glucose for 3 days. Compared to normal glucose, high glucose significantly decreased mRNA and protein expressions of podocin and nephrin...

Development of a Convenient In Vivo Hepatotoxin Assay Using a Transgenic Zebrafish Line with Liver-Specific DsRed Expression

Previously we have developed a transgenic zebrafish line (LiPan) with liver-specific red fluorescent protein (DsRed) expression under the fabp10a promoter. Since red fluorescence in the liver greatly facilitates the observation of liver in live LiPan fry, we envision that the LiPan zebrafish may provide a useful tool in analyses of hepatotoxicity based on changes of liver red...

Optimal staging system for predicting the prognosis of patients with hepatocellular carcinoma in China: a retrospective study

Background Several staging systems have been developed to evaluate patients with hepatocellular carcinoma (HCC), including the China Staging System (CS), the American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) staging system, and seventh edition; the Barcelona Clinic Liver Cancer (BCLC) staging system, and Cancer of the Liver Italian Program (CLIP) staging...

Rhizoma Paridis Saponins Suppresses Tumor Growth in a Rat Model of N-Nitrosomethylbenzylamine-Induced Esophageal Cancer by Inhibiting Cyclooxygenases-2 Pathway

Rhizoma Paridis Saponins (RPS), a natural compound purified from Rhizoma Paridis, has been found to inhibit cancer growth in vitro and in animal models of cancer. However, its effects on esophageal cancer remain unexplored. The purpose of this study was to investigate the effects of RPS on tumor growth in a rat model of esophageal cancer and the molecular mechanism underlying the...

Xmrk, Kras and Myc Transgenic Zebrafish Liver Cancer Models Share Molecular Signatures with Subsets of Human Hepatocellular Carcinoma

Previously three oncogene transgenic zebrafish lines with inducible expression of xmrk, kras or Myc in the liver have been generated and these transgenic lines develop oncogene-addicted liver tumors upon chemical induction. In the current study, comparative transcriptomic approaches were used to examine the correlation of the three induced transgenic liver cancers with human...

Role of Sema4C in TGF-β1-induced mitogen-activated protein kinase activation and epithelial–mesenchymal transition in renal tubular epithelial cells

Background. The p38 mitogen-activated protein kinase (p38 MAPK) is an important intracellular signal transduction pathway involved in TGF-β1-induced epithelial–mesenchymal transition (EMT). Sema4C, a member of the semaphorin family, was found to be essential for the activation of p38 MAPK. However, the role of Sema4C in promoting TGF-β1-induced EMT is unclear. Methods. Renal...

A statistical method (cross-validation) for bone loss region detection after spaceflight

Astronauts experience bone loss after the long spaceflight missions. Identifying specific regions that undergo the greatest losses (e.g. the proximal femur) could reveal information about the processes of bone loss in disuse and disease. Methods for detecting such regions, however, remains an open problem. This paper focuses on statistical methods to detect such regions. We...

Association of −27T>C and its haplotype at the putative promoter for IgA-specific receptor gene with IgA nephropathy among the Chinese Han population

Variation in IGHMBP2 is not associated with IgA nephropathy in independent studies of UK Caucasian and Chinese Han patients

Background. IgA nephropathy is a major cause of end-stage renal disease worldwide. Its aetiology is poorly understood but there is good evidence for a major genetic component, although to date, no gene has been conclusively identified. We describe a new UK multicentre DNA collection assembled to investigate this. A Japanese genome-wide analysis recently reported that common...

BCRP gene polymorphisms are associated with susceptibility and survival of diffuse large B-cell lymphoma

To date, the biological significance of breast cancer resistance protein (BCRP) G34A and C421A polymorphisms is largely unknown. Analysis of these two polymorphisms in 156 diffuse large B-cell lymphoma (DLBCL) patients and 376 control subjects revealed an increased risk of DLBCL associated with variant BCRP 421 genotypes (CA and AA), when compared with the wild-type CC genotype...

Association of MEGSIN 2093C–2180T haplotype at the 3′ untranslated region with disease severity and progression of IgA nephropathy

Background.MEGSIN is a gene predominantly expressed in the renal mesangium, and is upregulated in IgA nephropathy (IgAN). Our previous study has shown that the 2093C and 2180T alleles at the 3′ untranslated region (3′UTR) of the gene are associated with susceptibility to IgAN, but the relationships of these genetic variants with the clinical manifestations and renal histological...
