EZH2 inhibition promotes ANGPTL4/CREB1 to suppress the progression of ulcerative colitis.

Aims: Enhancer of zeste homolog 2 (EZH2) is associated with ulcerative colitis development. However, the mechanism of EZH2 in ulcerative colitis progression remains unclear.

Main Methods: Lipopolysaccharide (LPS)-treated Caco-2 cells and dextran sodium sulfate (DSS)-treated mice were used as model of ulcerative colitis.

Synergistic antitumor effect of puerarin combined with 5-fluorouracil on gastric carcinoma.

Combination chemotherapy is a crucial method in the treatment of gastric cancer. The aim of the present study was to investigate the inhibitory effects of puerarin and 5‑fluorouracil (5‑FU) on BGC‑823 gastric cancer cells in vitro and in vivo. The in vitro growth inhibition of puerarin or 5‑FU alone or combined on BGC‑823 cells was determined using a cell counting kit 8 (CCK‑8) on living cells.

XPD Asp312Asn polymorphism and esophageal cancer risk: an update meta-analysis based on 3928 cases and 6012 controls.

Background: Although xeroderma pigmentosum group D (XPD) was reported to be related with esophageal cancer (EC) risk, the results remained inconsistent. The aim of this meta-analysis was to make a more precise estimation of the relationship between XPD Asp312Asn polymorphism and EC risk.

Methods: We searched PubMed, Web of Science, Embase, Medline, CNKI and Chinese Biomedical database, covering all publications (up to May, 2014).

Potential effects of Mina53 on tumor growth in human pancreatic cancer.

Myc-induced nuclear antigen (Mina53) is a protein with a molecular weight of 53 kDa expression of which is induced by c-Myc. Increased expression of Mina53 is documented in some human carcinomas. In this study, we found markedly increased Mina53 expression in pancreatic cancer tissue specimens.

Clinical significance of EBP50 overexpression assessed by quantum dot analysis in gastric cancer.

Ezrin-radixin-moesin-binding phosphoprotein 50 (EBP50) is a postsynaptic density-95/disc-large/zonula occludens-1 (PDZ) homologous domain-containing protein that is involved in cell signaling. EBP50 regulates cell apoptosis, proliferation and invasion. In the present study, the prognostic impact factor of EBP50 expression was evaluated using a quantum dot (QD)-based assay and immunohistochemistry (IHC).

The detection of EBP50 expression using quantum dot immunohistochemistry in pancreatic cancer tissue and down-regulated EBP50 effect on PC-2 cells.

Ezrin-radixin-moesin-binding phosphoprotein 50 (EBP50) is a putative tumor suppressor that is correlated with many human cancers. However, the function of EBP50 in pancreatic cancer (PC) has not been described. In this paper, the EBP50 expression level in PC tissues was characterized.

Noscapine induces mitochondria-mediated apoptosis in human colon cancer cells in vivo and in vitro.

Noscapine, a phthalide isoquinoline alkaloid derived from opium, has been widely used as a cough suppressant for decades. Noscapine has recently been shown to potentiate the anti-cancer effects of several therapies by inducing apoptosis in various malignant cells without any detectable toxicity in cells or tissues. However, the mechanism by which noscapine induces apoptosis in colon cancer cells remains unclear.

Overexpression of Dickkopf-3 induces apoptosis through mitochondrial pathway in human colon cancer.

Aim: To investigate the mechanisms of the biological roles of Dickkopf-3 (Dkk-3) in cell invasion, survival and apoptosis in colon cancer cells.

Methods: Three human colon cancer cell lines, i.e.

EBP50 gene transfection promotes 5-fluorouracil-induced apoptosis in gastric cancer cells through Bax- and Bcl-2-triggered mitochondrial pathways.

5-Fluorouracil (5-FU) plays an important role in the chemotherapy of advanced gastric cancer. However, genetic factors that affect therapeutic efficacy of 5-FU warrant further investigation. In the present study, using stable transfection of the ezrin-radixin-moesin-binding phosphoprotein 50 (EBP50) gene, we explored the genetic influences on 5-FU-induced apoptosis of human gastric cancer cells.

[Expression of Dickkopf-3 in esophageal squamous cell carcinoma].

Objective: To investigate the expression of Dickkopf-3 (Dkk-3) in esophageal cancer and normal esophageal tissue and the relationship between Dkk-3 expression and the biological behavior of esophageal cancer.

Methods: Immunohistochemical method of S-P was used to examine Dkk-3 expression in 69 cases of esophageal squamous cell carcinoma and 5 cases of normal esophageal tissue with non-tumor tissue microarray and the results were analyzed and correlated with their clinical and pathological features.

Results: Positive Dkk-3 expression was observed in 65.

Noscapine induces mitochondria-mediated apoptosis in gastric cancer cells in vitro and in vivo.

Purpose: Noscapine plays an important role in the regulation of cell growth and death. It has been reported to potentiate the anti-tumor effect by inducing apoptosis in various malignant cells. However, the mechanism of inducing apoptosis in gastric cancer cells by this agent remains to be clarified.
