miR-223-RhoB signaling pathway regulates the proliferation and apoptosis of colon adenocarcinoma.

MicroRNAs (miRNAs) can function as tumor suppressor or oncogenic genes. The putative targets of miR-223 include tumor suppressor gene, RhoB. Here we sought to investigate the role of miR-223-RhoB signaling pathway in proliferation of colon cancer. We used Western blot, immunofluorescence staining, or RT-PCR to detect expression levels of miR-223 and RhoB in colon adenocarcinoma and adjacent non-cancerous tissue samples, or in human colon adenocarcinoma cell lines. MTT assay was used to determine proliferati...

Sporadic colon cancer in Lebanon: A clinicopathological study.

Colon cancer is a heavy public health burden. No data has been previously published on colon cancer epidemiology in Lebanon. The objective of this study was to report the clinical and pathological features of surgically operated colon cancer. From July 2005 to July 2012, 187 sporadic colonic tumors were operated in Hotel-Dieu de France Hospital (Beirut, Lebanon). Demographic, clinical, pathological and staging data was collected. The male: female sex ratio was 1.3 and the mean age at diagnosis was 66.0 year...

Fascin protein stabilization by miR-146a implicated in the process of a chronic inflammation-related colon carcinogenesis model.

In sporadic colon tumors, multistep process of well-known genetic alterations accelerates carcinogenesis; however, this does not appear to be the case in inflammation-related ones. We previously established a model of inflammation-related colon carcinogenesis using human colonic adenoma cells, and identified fascin as a driver gene of this process. We analyzed the microRNAs involved in the stable fascin expression in colon adenocarcinoma cells.

Analysis of lncRNA-Associated ceRNA Network Reveals Potential lncRNA Biomarkers in Human Colon Adenocarcinoma.

Long non-coding RNAs (lncRNAs) acting as competing endogenous RNAs (ceRNAs) play significant roles in the development of tumors, but the functions of specific lncRNAs and lncRNA-related ceRNA networks have not been fully elucidated for colon adenocarcinoma (COAD). In this study, we aimed to clarify the lncRNA-microRNA (miRNA)-mRNA ceRNA network and potential lncRNA biomarkers in COAD.

Demographic Trends and KRAS/BRAF Mutations in Colorectal Cancer Patients of South China: a Single-site Report.

The incidence of colorectal cancer (CRC) is increasing in China. Here, we aimed to evaluate the latest demographic trends and KRAS/BRAF mutations status of Chinese CRC. 5546 CRC patients diagnosed from 2010 to 2017 were involved. KRAS exon 2 and BRAF mutations were detected by Sanger sequencing and high-resolution melting analysis or allelic-specific probe method. Gene mutation profiles and clinicopathologic characteristics of 5495 patients were analyzed. The joinpoint regression model was used to predict t...

Ectopic expression of band 3 anion transport protein in colorectal cancer revealed in an autoimmune hemolytic anemia patient.

Cancer patients occasionally have anemia with high mean corpuscular volume in addition to iron deficiency anemia. Secondary autoimmune hemolytic anemia (AIHA) following cancer is also observed with low frequency. To date, no causal mechanisms for these disease states have been reported. Here, we present the case of an 80-year-old woman with AIHA that was resistant to prednisolone. Further examinations revealed primary adenocarcinoma of the sigmoid colon and primary squamous cell carcinoma in the right lung....

Single nucleotide polymorphisms in the MYLKP1 pseudogene are associated with increased colon cancer risk in African Americans.

Pseudogenes are paralogues of functional genes historically viewed as defunct due to either the lack of regulatory elements or the presence of frameshift mutations. Recent evidence, however, suggests that pseudogenes may regulate gene expression, although the functional role of pseudogenes remains largely unknown. We previously reported that MYLKP1, the pseudogene of MYLK that encodes myosin light chain kinase (MLCK), is highly expressed in lung and colon cancer cell lines and tissues but not in normal lung...

circCTIC1 promotes the self-renewal of colon TICs through BPTF-dependent c-Myc expression.

Colon tumor is a conman tumor in the world. There are kinds of cells in colon tumor bulk, and only a small population can initiate tumor efficiently and termed as tumor initiating cells (TICs). With self-renewal and differentiation capacities, colon TICs drive colon tumorigenesis, metastasis and relapse. However, the molecular mechanisms of colon TICs self-renewal are elusive. Here, we found a circular RNA (circCTIC1) was highly expressed in colon tumor and colon TICs. circCTIC1 knockdown impaired the self-...

Right Colon Resection for Colon Cancer: Does Surgical Approach Matter?

Surgical resection with curative intent remains the standard of care for colon cancer. This study aims to compare the 30-day outcomes and oncologic results following open, laparoscopic, and robot-assisted right colon resection for colon cancer using the Targeted Colectomy American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.

Acid ceramidase inhibition sensitizes human colon cancer cells to oxaliplatin through downregulation of transglutaminase 2 and β1 integrin/FAK-mediated signalling.

Acid ceramidase (ASAH1) has been implicated in the progression and chemoresistance in different cancers. Its role in colon cancer biology and response to standard chemotherapy has been poorly addressed so far. Here, we have investigated ASAH1 expression at the protein level in human colon cancer cell lines and tissues from colon cancer patients, and have examined in vitro the possible link between ASAH1 expression and functional activity of p53 protein whose inactivation is associated with the progression f...

Nature-inspired development of unnatural meroterpenoids as the non-toxic anti-colon cancer agents.

Structural analogues of anti-cancer natural product, dysideanone, were synthesized starting from Wieland-Miescher ketone derivative. In vitro studies have been conducted to evaluate the anti-cancer potential of these unnatural meroterpenoids against colon cancer. Synthesized carbotetracycles were found to be more active as compared to their acyclic carbinol-derivatives. Unnatural carbotetracycles 4b-e, 4h, 4i and 12 were found to be highly effective against the human colon adenocarcinoma cells with IC conc...

Recurrence Risk After Up-to-Date Colon Cancer Staging, Surgery, and Pathology: Analysis of the Entire Swedish Population.

Developments in the quality of care of patients with colon cancer have improved surgical outcome and thus the need for adjuvant chemotherapy.

Dro1/Ccdc80 inactivation promotes AOM/DSS induced colorectal carcinogenesis and aggravates colitis by DSS in mice.

Colorectal carcinogenesis is a progressive multistep process involving the sequential accumulation of genetic alterations in tumor suppressor genes and oncogenes. Down regulated by oncogenes 1 (Dro1/Ccdc80) has been shown to be a potent tumor suppressor of colorectal carcinogenesis in the genetic ApcMin/+ mouse model. In ApcMin/+ mice loss of DRO1 strongly increases colonic tumor multiplicity and leads to the regular formation of adenocarcinoma in the colon. To investigate DRO1`s role in chemically induced ...

Causes of mortality in older patients with stage 3 colon cancer.

Life expectancy plays a key role in the selection of patients with stage III colon cancer for adjuvant chemotherapy, but little is known about causes of mortality in older patients with colon cancer. We aimed to examine causes of death in this population and compare these causes between patients who received chemotherapy and those who did not. Specifically, we chose to examine the rates of death related to recurrent colon cancer versus non colon cancer.

Endoscopic Treatment of Early Barrett's Adenocarcinoma and Dysplasia: Focus on Submucosal Cancer.

Eradication of early Barrett's neoplasia by endoscopic resection and radiofrequency ablation is safe and effective. In T1b adenocarcinoma, standard of care remains controversial. We investigated the therapeutic outcome between high-grade dysplasia (HGD)/mucosal adenocarcinoma and submucosal adenocarcinoma in Barrett's patients. We hypothesised similar outcome in low-risk (LR) T1b compared to T1a/HGD.

Anomalous course of the sigmoid colon and the mesosigmoid encountered during colectomy. A case report of a redundant loop of sigmoid colon.

Introduction Sigmoid colon constitutes a part of the large intestine that presents several congenital anatomic variations. In particular, the presence of a redundant loop of sigmoid colon is of tremendous importance for surgeons, obstetricians and radiologists, since it is closely related to multiple pathological conditions and functional implications of the neighboring anatomical structures.

Anti-metastatic effect of metformin via repression of interleukin 6-induced epithelial-mesenchymal transition in human colon cancer cells.

Metformin, a first-line drug used to treat type 2 diabetes, has also been shown to have anticancer effects against a variety of malignancies, including colorectal cancer. Although inhibition of the mTOR pathway is known to be the most important mechanism for the antitumor effects of metformin, other mechanisms remain unclear. The purpose of this study was to identify the antitumor mechanism of metformin in colorectal cancer using high-throughput data, and then test the mechanism experimentally. We identifie...

Is Robotic Complete Mesocolic Excision Feasible for Transverse Colon Cancer?

Laparoscopic complete mesocolic excision (CME) for transverse colon cancer is technically challenging. Robotic technology has been developed to reduce technical limitations of laparoscopy. Yet, no data are available on the role of robotic approach for CME of transverse colon cancer. The aim of this study is to evaluate the feasibility and short-term outcomes of robotic CME in this subset of colon cancer.

MET amplification, expression, and exon 14 mutations in colorectal adenocarcinoma.

MET amplification, expression, and splice mutations at exon 14 result in dysregulation of the MET signaling pathway. The aim of this study was to identify the relationship between MET amplification, protein or mRNA expression, and mutations in colorectal cancer (CRC). MET immunohistochemistry (IHC) was used for MET protein expression analysis and fluorescence in situ hybridization (FISH) was used for MET amplification detection. Both analyses were performed in tissue microarrays (TMA) containing 294 of colo...
