Randomized phase II study of TX followed by XELOX versus the reverse sequence for chemo-naive patients with metastatic gastric cancer.

Unlabelled: This research found that the clinical outcomes (PFS, ORR, OS) of the non-platinum-based doublet regimen (docetaxel capecitabine combination) were similar to those of the platinum-based (oxaliplatin capecitabine combination) when used as first line therapy for MGC patients.

Background: Docetaxel, platinum and fluorouracil are the three most important drugs in the treatment of MGC. This study was to compare clinical outcomes of the docetaxel capecitabine combination and the oxaliplatin capecitabine combination as first-line therapy in MGC patients.

Design, synthesis and anti-cancer activity of pyrrole-imidazole polyamides through target-downregulation of c-kit gene expression.

Pyrrole-imidazole polyamide (PIP) can specifically bind in the B-DNA minor groove that has been used in several biological applications, such as anti-cancer activity, gene expression and translation control, and visualization of complex genomic areas. c-kit is a family member of the Tyrosine Kinase (RTK) type III receptor and plays a vital role in tumor growth, proliferation, differentiation, and cell apoptosis; however, its mutations and overexpression induce tumor dysfunction. Here, we designed and synthesized five matched PIPs that can recognize and bind to the DNA sequence in the oncogene c-kit promoter region, and evaluated their anti-cancer activity.

Design, synthesis and biological evaluation of 2-methyl-(1,1'-biphenyl)-pyrimidine conjugates.

Small molecule inhibitors of biphenyl structure as core backbone have shown a significant effect on PD-1/PD-L1 axis, and 2-amino-pyrimidine structure is a promising privileged scaffold in medicinal chemistry and drug discovery. We designed by combination principles and synthesized 27 novel compounds with N-((2-methyl-[1,1'-biphenyl]-3-yl)methyl)pyrimidin-2-amine as a basic skeletal structure, and their anti-cancer activity was evaluated. Among compounds, 15a-d and 16b displayed strong anti-cancer effects on 9 tested cancer cell lines, in particular, the 16b did the highest inhibitive activity, but against HepG2 cells, and possessed the lowest IC value of 2.

Mesenchymal stem cells-regulated Treg cells suppress colitis-associated colorectal cancer.

Introduction: Previous studies have produced controversial results regarding whether mesenchymal stem cells (MSCs) promote or inhibit tumor development. Given the dual role of MSCs in inflammation and cancer, in this study the colitis-associated colorectal cancer (CAC) model was used to examine whether umbilical cord tissue-derived MSCs could prevent neoplasm by inhibiting chronic inflammation.

Methods: MSCs were obtained and identified using flow cytometry.

LRP5 polymorphism-A potential predictor of the clinical outcome in advanced gastric cancer patients treated with EOF regimen.

Purpose: Wnt pathways control key biological processes that potentially impact on tumor progression and patient survival. The present study analyzed the polymorphism of lipoprotein-related receptor 5 (LRP5) (gene with key functions in Wnt signaling) and its impact on the response to chemotherapy and survival of patients with advanced gastric cancer (AGC).

Methods: A total of 107 consecutive patients with AGC treated with first-line chemotherapy of EOF regimen were enrolled in the present retrospective study.
