High throughput gene expression profiling has showed great promise in providing insight into molecular mechanisms. Metastasis-related mRNAs may potentially enrich genes with the ability to predict cancer recurrence,therefore we attempted to build a recurrence-associated gene signature to improve prognostic prediction of colorectal cancer (CRC). We identified 2848 differentially expressed mRNAs by analyzing CRC tissues with or without metastasis. For the selection of prognostic genes, a LASSO Cox regression model was employed...

Systemic inflammation was recognized as an essential factor contributing to the development of malignancies. This study aimed to investigate the prognostic value of pre-operative lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) in patients with colorectal liver-only metastases (CLOM) undergoing hepatectomy. We retrospectively enrolled 150 consecutive patients with CLOM between 2000 and 2012. The optimal cutoff values of continuous LMR, NLR, and PLR were determined using the receiver operating characteristic curve analysis...

BACKGROUND: Increased serum levels of vitamin D and calcium have been associated with lower risks of colorectal cancer (CRC) incidence and mortality. These inverse associations may be mediated by the vitamin D receptor (VDR) and the calcium-sensing receptor (CASR). We investigated genetic variants in VDR and CASR for their relevance to CRC prognosis. METHODS: A population-based cohort of 531 CRC patients diagnosed from 1999 to 2003 in Newfoundland and Labrador, Canada, was followed for mortality and cancer recurrence until April 2010...

BACKGROUND: Epithelial-mesenchymal transition (EMT) is one of the main events in colorectal cancer (CRC) spread. Snail-1 is a zinc transcription factor that mediates EMT in tumor cells probably by down-regulation of E-cadherin and claudin-1. OBJECTIVES: To detect the expression of epithelial markers (claudin-1 and E-cadherin) and mesenchymal markers (snail-1 and vimentin) in primary cancer colon. Also, to select stage II cancer patients of a high risk that can benefit from postoperative adjuvant chemotherapy...

Though the long noncoding RNA colon cancer associated transcript-1 (CCAT-1) has been shown to be involved in tumors of other tissues, its involvement in cervical cancer is still unknown. Therefore, the aim of this study was to investigate the molecular mechanism of CCAT-1 in cervical cancer. We quantified the expression of CCAT-1 long noncoding RNA in samples of cervical cancer tissue by real-time PCR. Effects of CCAT-1 expression on the proliferation and apoptosis of HeLa and CaSki cells were assessed by cell-count, colony-formation, and flow cytometry assays...

OBJECTIVES: To investigate the relevance of lymphangiogenic gene expression in primary and liver metastasis of colorectal cancer (CRC) and identify determinants of lymphatic invasion. BACKGROUND: Lymphatic development promoting vascular endothelial growth factor C (VEGFC) is associated with poor outcome in primary CRC. For colorectal liver metastasis (CRLM), intrahepatic lymph invasion and lymph node metastasis are poor prognostic factors. Exact biological factors promoting lymphatic involvement remain elusive, just as the association with molecular subtypes of CRC...

PURPOSE: Although general surgeons normally perform laparoscopic colectomies in patients with colon cancer, the procedure is also indicated for serosa-negative tumors (≤ cT3). Serosal invasion (T4a) is regarded as a potential risk factor for peritoneal dissemination due to pneumoperitoneum effects and tumor manipulation during laparoscopic colectomy. We compared short- and long-term outcomes of patients who underwent laparoscopic and open colectomies for serosa-involving colon cancer (pT4a) and had a preoperative diagnosis of cancer without serosal invasion (≤cT3)...

Gastric cancer (GC) is one of the most common tumors worldwide. Standard treatment after early detection involves surgical excision (recurrence is possible), and metastatic gastric cancer is refractory to immuno-, radio-, and most harmful chemotherapies. Various natural compounds have shown efficacy in killing different cancers, albeit not always specifically. In this study, we show that dandelion root extract (DRE) specifically and effectively suppresses proliferation and migration in human gastric cells without inducing toxicity in noncancerous cells...

Cancer stem cells (CSCs) are capable of reconstructing cancer tissues, are involved in both recurrence and metastasis, and contribute to therapeutic resistance. Therefore, elucidating the molecular mechanism in CSCs is important to successfully treat unresectable cancers. Previously we observed that colon cancer stem-like cells can be induced from human colon cancer cell lines by retrovirally introducing OCT3/4, SOX2 and KLF4, and we have designated such cells as induced cancer stem cells (iCSCs). In the current study, we used iCSCs to evaluate the molecular mechanism of colon CSCs and developed new methods to control them...

Abundance of the ATPase-binding cassette (ABC) transporters and deranged self-renewal pathways characterize the presence of cancer stem cells (CSCs) in gastrointestinal cancers (GI cancers), which play crucial roles in tumorigenesis, chemotherapy resistance, tumor recurrence, and cancer metastasis. Therefore, in order to ensure high cure rates, chemoquiescence, CSCs should be ablated. Recent advances in either understanding CSCs or biomarker identification enable scientists to develop techniques for ablating CSCs and clinicians to provide cancer cure, especially in GI cancers characterized by inflammation-driven carcinogenesis...

Despite significant therapeutic progress in recent years, inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, remains a challenge regarding its pathogenesis and long-term complications. New concepts have emerged in the management of this disease, such as the "treat-to-target" concept, in which mucosal healing plays a key role in the evolution of IBD, the risk of recurrence and the need for surgery. Endoscopy is essential for the assessment of mucosal inflammation and plays a pivotal role in the analysis of mucosal healing in patients with IBD...

Defining the genetic drivers of cancer progression is a key in understanding disease biology and developing effective targeted therapies. Chromosome rearrangements are a common feature of human malignancies, but whether they represent bona fide cancer drivers and therapeutically actionable targets, requires functional testing. Here, we describe the generation of transgenic, inducible CRISPR-based mouse systems to engineer and study recurrent colon cancer-associated EIF3E-RSPO2 and PTPRK-RSPO3 chromosome rearrangements in vivo...
