The effect of chemotherapeutic agents is limited as a result of drug resistance, which demands prompt solutions provided by clinical studies. To date, the underlying mechanisms of chemotherapy resistance are relatively unknown. Metastasis-associated in colon cancer 1 (MACC1) is an oncogene associated with the progression and prognosis of gastric cancer (GC). Bioinformatic analysis revealed that MACC1 is positively associated with fatty acid synthase (FASN), a major enzyme of lipogenesis, and drives chemoresistance to oxaliplatin in GC...

In colorectal cancer, gain-of-function mutations in KRas play a critical role in malignant transformation. Tumor growth in colorectal cancer is known to be promoted by the intestinal myofibroblasts (IMFs) that localize adjacent to the cancer cells, but the mechanisms of interaction between KRas-mutated cancer cells and the myofibroblasts remain unclear. Here, we investigated the effects of KRas-mutated cells on the behavior of myofibroblasts by using mouse primary IMFs and cells of an IMF cell line (LmcMF) and a mouse colon epithelial cell line (aMoC1)...

Helicobacter pylori is a highly successful human bacterium, which is exceptionally equipped to persistently inhabit the human stomach. Colonization by this pathogen is associated with gastric disorders ranging from chronic gastritis and peptic ulcers to cancer. Highly virulent H. pylori strains express the well-established adhesins BabA/B, SabA, AlpA/B, OipA, and HopQ, and a type IV secretion system (T4SS) encoded by the cag pathogenicity island (PAI). The adhesins ascertain intimate bacterial contact to gastric epithelial cells, while the T4SS represents an extracellular pilus-like structure for the translocation of the effector protein CagA...

A series of novel indazole-based diarylurea derivatives targeting c-kit were designed by structure-based drug design. The derivatives were prepared and their antiproliferative activities were evaluated against human colon cancer HCT-116 cell line and hepatocellular carcinoma PLC/PRF/5 cell line. The antiproliferative activities demonstrated that six out of nine compounds exhibited comparable activities with Sorafenib against HCT-116. The structure-activity relationship (SAR) analysis indicated that the indazole ring part tolerated different kinds of substituents, the N position of the central pyridine ring played key roles in antiproliferative activity...

OBJECTIVE: Osteosarcoma is one of the most common malignant bone tumors. The mechanisms of osteosarcoma development and invasion have been studied for periods of time, yet targeted therapy for improving survival has not been well established. Histone lysine methyltransferase NSD2 was frequently overexpressed in multiple types of cancer such as multiple myeloma, stomach and colon cancer, and the overexpression of it usually associated with aggressiveness tumor type. However, the expression status and function of NSD2 are still ambiguous in osteosarcoma...

Colon cancer is characterized by its fast progression and poor prognosis, and novel agents of treating colon cancer are urgently needed. WZ35, a synthetic curcumin derivative, has been reported to exhibit promising antitumor activity. Here, we investigated the in vitro and in vivo activities of WZ35 and explored the underlying mechanisms in colon cancer cell lines. WZ35 treatment significantly decreased the cell viability associated with G2/M cell cycle arrest and apoptosis induction in colon cancer cell lines...

Accumulating evidence indicates that natural ent-kaurane diterpenoids show great potential for medical treatment of different pathological conditions including cytotoxicity, antibacterial, and anti-inflammatory activity. Among a variety of diterpenoids tested, (-)-pseudoirroratin A displayed a promising antitumor property in vitro and in vivo. However, this diterpenoid could merely be isolated in a limited amount from a rare source of Isodon pseudoirrorata. To overcome such scanty source, we developed a novel, facile, and efficient semisynthetic strategy to prepare (-)-pseudoirroratin A from natural (-)-flexicaulin A, which can be expediently obtained from I...

In addition to locally controlling the tumor, hypofractionated radiotherapy (RT) particularly aims to activate immune cells in the RT-modified microenvironment. Therefore, we examined whether hypofractionated RT can activate dendritic cells (DCs), induce immune cell infiltration in tumors, and how the chronology of immune cell migration into tumors occurs to gain knowledge for future definition of radiation breaks and inclusion of immunotherapy. Colorectal cancer treatments offer only limited survival benefit, and immunobiological principles for additional therapies need to be explored with preclinical models...

The American Society of Nephrology recommends against routine cancer screening among asymptomatic patients receiving maintenance dialysis on the basis of limited survival benefit. To determine the frequency of colorectal cancer screening among patients on dialysis and the extent to which screening tests were targeted toward patients at lower risk of death and higher likelihood of receiving a kidney transplant, we performed a cohort study of 469,574 Medicare beneficiaries ages ≥50 years old who received dialysis between January 1, 2007 and September 30, 2012...

INTRODUCTION: The use of a self-expanding metallic stent as a bridge to surgery in acute malignant left colonic obstruction has been suggested as an alternative treatment to emergency surgery. The aim of the present study was to compare the morbi-mortality, cost-benefit and long-term oncological outcomes of both therapeutic options. METHODS: This is a prospective, comparative, controlled, non-randomized study (2005-2010) performed in a specialized unit. The study included 82 patients with left colon cancer obstruction treated by stent as a bridge to surgery (n=27) or emergency surgery (n=55) operated with local curative intention...

Investigation of side effects and solubility of anticancer drugs is a major challenge in chemotherapy science. Thus, design and synthesis of cisplatin analogs with higher lipophilicity as novel water-soluble anticancer drugs is valuable. In this work, two new Pt (II) complexes were synthesized with formula cis-[Pt (NH3)2(amylgly)] NO3 and cis-[Pt (amylamine)2(amylgly)]NO3; where gly is penthyl glycine as an amino acid. The new compounds were synthesized and extensively characterized using analytical techniques; spectroscopic methods and conductivity measurement...

Genome-wide association studies (GWASs) identified over 500 single nucleotide polymorphisms (SNPs) influencing cancer risk. It is logical to expect the cancer-associated genes to cluster in pathways directly involved in carcinogenesis, e.g. cell cycle. Nevertheless, analyses of the GWAS-detected cancer risk genes usually show no or weak enrichment by known cancer genes.We hypothesized that GWAS-detected cancer risk-associated genes function as upstream regulators of the genes directly involved in carcinogenesis...

The proband was a 67-year-old man with transverse and sigmoid colon cancer. Microsatellite instability analysis revealed a high frequency of microsatellite instability, and immunohistochemical staining showed the absence of both MLH1 and PMS2 proteins in the sigmoid colon cancer tissue specimens from the patient. DNA sequencing revealed a nucleotide substitution c.543C>T in MLH1, but this variant did not substitute an amino acid. The MLH1 c.543C>T variant was located 3 bases upstream from the end of exon 6 and created a new splice donor site 4 bases upstream from the end of exon 6...
