Epigenetic regulation of RARB overcomes the radio-resistance of colorectal carcinoma cells via cancer stem cells.

Cancer stem cells (CSCs) are able to survive after cancer therapies, leading to cancer progression and recurrence in colorectal carcinoma (CRC). Therapies targeting CSCs are believed to be promising strategies for efficiently eradicating cancers. This study was to investigate that how retinoic acid receptor beta (RARB) affected the biological characteristics of CSCs and radio-resistance in CRC and the epigenetic mechanism.

VSNL1 Promotes Cell Proliferation, Migration, and Invasion in Colorectal Cancer by Binding with COL10A1.

Objective: The study aimed to explore the role of VSNL1/COL10A1 axis in colorectal cancer.

Methods: The differential-expressed mRNA in colorectal cancer tissues and adjacent tissues were analyzed through GEO database and GEPIA database. The target genes of mRNA were predicted through the Starbase database, and the targeting relationship of mRNA was verified by co-IP assay.

Paired-like homeodomain transcription factor 2 strengthens chemoresistance in colorectal cancer by activating the Wnt/β-catenin axis.

The purpose of this study was to determine the mechanism of paired-like homeodomain transcription factor 2 (PITX2) in the chemoresistance of colorectal cancer (CRC) via the upregulation of the Wnt/β-catenin axis. CRC cells were persistently exposed to increasing 5-fluorouracil (5-FU) concentrations to establish 5-FU-resistant cells. Functional assays were conducted to examine cell viability, proliferation, and cell cycle.

LncRNA TTN-AS1 sponges miR-376a-3p to promote colorectal cancer progression via upregulating KLF15.

Aims: Long non-coding RNAs (lncRNAs) play key roles in regulating multiple cancers. TTN-AS1 was reported to function in several human malignancies. However, the biological function of TTN-AS1 in colorectal cancer (CRC) has not been explored.

High expression of ZBED1 affects proliferation and apoptosis in gastric cancer.

Background: ZBED1 (zinc finger BED-type containing 1) is a transcription factor. However, its expression, role and clinical significance in cancer are unclear. The purpose of this study is to investigate the expression of ZBED1 and its effect on the proliferation of gastric cancer (GC).

Transcatheter arterial chemoembolization plus sorafenib versus transcatheter arterial chemoembolization alone to treat advanced hepatocellular carcinoma: a meta-analysis.

Background: Many studies have combined sorafenib with transcatheter arterial chemoembolization (TACE) to treat patients with advanced hepatocellular carcinoma (HCC), but the results are disputable. Thus, we conducted this meta-analysis to assess the efficacy and safety of the combination treatment in patients with advanced HCC.

Methods: Clinical data were collected from a computer search of literature published from January 2009 to June 2016 in PubMed, Web of Science, the Cochrane Library, China National Knowledge Infrastructure (CNKI), Wan Fang and the China Science and Technology Journal Database (CSTJ).

Survival changes in Patients with Synovial Sarcoma, 1983-2012.

Synovial sarcoma (SyS) is a rare malignancy that typically invades the extremities and occurs predominantly in adolescents. Studies on incidence and survival in SyS that were based on a large population had not been reported yet. To evaluate changes in incidence and survival in SyS over three decades, we accessed data on SyS cases in each decade between 1983 and 2012 (1983-1992, 1993-2002, and 2003-2012) from the Surveillance, Epidemiology, and End Results (SEER) database.

Quantitative assessment of caveolin-1 G14713A polymorphism and cancer susceptibility in the Asian population.

Purpose: The relationship between caveolin-1 (CAV1) G14713A polymorphism and cancer susceptibility remains inconclusive. The current meta-analysis was performed on the basis of a systematic search in electronic databases for a more precise estimation of the associations.

Methods: Odds ratio (OR) with 95% confidence interval (CI) was used to estimate the pooled effect.

Antitumor activity of chloroquine in combination with Cisplatin in human gastric cancer xenografts.

Purpose: To investigate the antitumor activity and mechanism of chloroquine (CQ) in combination with cisplatin (DDP) in nude mice xenografted with gastric cancer SGC7901 cells.

Materials And Methods: 35 cases of gastric cancer patients with malignant ascites were enrolled and intraperitoneal cisplatin injection was performed. Ascites were collected before and 5 days after perfusion for assessment of autophagy levels in cancer cells.

Changing patterns of Serum CEA and CA199 for Evaluating the Response to First-line Chemotherapy in Patients with Advanced Gastric Adenocarcinoma.

Background: This study was designed to investigate the value of CEA and CA199 in predicting the treatment response to palliative chemotherapy for advanced gastric cancer.

Materials And Methods: We studied 189 patients with advanced gastric cancer who received first-line chemotherapy, measured the serum CEA and CA199 levels, used RECIST1.1 as the gold standard and analyzed the value of CEA and CA199 levels changes in predicting the treatment efficacy of chemotherapy.

Paclitaxel-loaded trimethyl chitosan-based polymeric nanoparticle for the effective treatment of gastroenteric tumors.

Gastroenteric cancer is one of the most prevalent cancers and is responsible for most cancer-related deaths worldwide. Paclitaxel (PTX), a classical microtubule inhibitor, is indicated in the treatment of gastric/gastroenteric cancers. In the present study, trimethyl chitosan (TMC)-loaded PTX (TMC-PTX) was prepared and evaluated for its therapeutic effect in gastric cancers.

Coexpression of SFRP1 and WIF1 as a prognostic predictor of favorable outcomes in patients with colorectal carcinoma.

Colorectal tumorigenesis is ascribed to the activity of Wnt signaling pathway in a ligand-independent manner mainly through APC and CTNNB1 gene mutations and in a ligand-dependent manner through low expression of Wnt inhibitors such as WNT inhibitory factor 1 (WIF1) and secreted frizzled related protein 1 (SFRP1). In this study we found that WIF1 protein expression was increased and SFRP1 was decreased significantly in CRC tissue versus normal tissue, and high expression of WIF1 was associated with big tumor diameters and deep invasion, and loss of SFRP1 expression was associated with the left lesion site, deep invasion, and high TNM stage. Among the four expression patterns (WIF+/SFRP1+, WIF+/SFRP1-, WIF-/SFRP1+, and WIF-/SFRP1-) only coexpression of WIF1 and SFRP1 (WIF+/SFRP1+) was associated with favorable overall survival, together with low TNM stage, as an independent prognostic factor as shown in a multivariate survival model.

Modulation effects of cordycepin on the skeletal muscle contraction of toad gastrocnemius muscle.

Isolated toad gastrocnemius muscle is a typical skeletal muscle tissue that is frequently used to study the motor system because it is an important component of the motor system. This study investigates the effects of cordycepin on the skeletal muscle contractile function of isolated toad gastrocnemius muscles by electrical field stimulation. Results showed that cordycepin (20 mg/l to 100 mg/l) significantly decreased the contractile responses in a concentration-dependent manner.
