2,3,5,4'-Tetrahydroxystilbene-2-O-β-D-glucoside (THSG) has been shown to have antioxidative and anti-inflammatory effects. Oxidative and inflammatory reactions are related to the development of colorectal carcinoma (CRC). In the present study, we characterized the preventive activities of THSG on colon carcinogenesis using the azoxymethane- (AOM-) mediated rat colon carcinogenesis model. F344 male rats were randomly divided into 5 groups (untreated and AOM model rats treated with or without THSG at 30, 150, or 250 mg/kg) after which the numbers of aberrant crypt foci (ACF) were assessed in the colon tissues of all rats...

Endometriosis-associated intestinal tumors represent the malignant transformation of gastrointestinal endometriosis. Approximately 50 cases have been reported in the literature. They are most commonly found among women aged 30-60 years, whereas exogenous hormone therapy and obesity are primary risk factors for the malignant transformation of endometriotic lesions. Clinical features simulate a primary colonic carcinoma. A high index of suspicion in conjunction with careful histological and immunohistochemical examination (CK7, CK20, CDX2, CD10, ER, and PR) is important for establishing a correct diagnosis...

BACKGROUND: Colorectal carcinoma (CRC) is one of the most common causes of cancer-related deaths. The mean age of patients with CRC ranges from 49 to 60 years. Pediatric CRC is unusual, which often escapes early diagnosis because of a lack of awareness of its occurrence in children. The association between the mutation of APC and the occurrence of CRC in the first decade of life remains unknown. CASE PRESENTATION: We report a 10-year-old child with CRC; he was diagnosed with stage IIIB advanced transverse colon cancer without distal metastases...

BACKGROUND AND PURPOSE: CYP1B1 and CYP1A1 are important extra hepatic cytochromes, expressed in the colon and implicated in the metabolism of dietary constituents and exogenous compounds. CYP1B1 expression is increased by pro-inflammatory cytokines and it has been recently implicated in regulation of blood brain barrier function. We investigated its involvement in the increased permeability of the intestinal epithelial barrier observed in inflammatory conditions. EXPERIMENTAL APPROACH: (IFNγ, 10 ng...

Background: Upon initial presentation, 25%-30% of patients with renal cell carcinoma have metastatic disease. Metastasis to the gastrointestinal tract is rare, but when it occurs, the large bowel is the least common site. Case Report: A 75-year-old white male presented with vague abdominal symptoms and worsening hemoglobin and hematocrit levels. Colonoscopy revealed a polyp in the distal portion of the sigmoid colon. Histologic and immunohistochemical analysis suggested metastatic papillary renal cell carcinoma...

1,4-benzothiazines have ameliorative effects through inhibition of COX-2 mediated STAT-3 pathways at G-protein couple receptor site. As per this scenario, we recently prepared and tested novel 1,4-benzothiazine derivatives against HT-29 human colon cancer cell line. Two compounds namely AR13 and AR15 showed higher inhibitions among all the synthesized compounds. In the present context, we conducted the in vivo antiproliferative action and identified the molecular mechanism associated to cytotoxic action of AR13 and AR15 in dimethylhydrazine (DMH) induced colorectal carcinoma (CRC) model...

The anti-tumor potential of oncolytic adenoviruses (CRAds) has been demonstrated in preclinical and clinical studies. While these agents failed to eradicate tumors when used as a monotherapy, they may be more effective if combined with conventional treatments such as radiotherapy or chemotherapy. This study seeks to evaluate the combination of a CRAd bearing a ∆24 deletion in E1A with valproic acid (VPA), a histone deacetylase inhibitor, for the treatment of human colon carcinomas. This combination led to a strong inhibition of cell growth both in vitro and in vivo compared to treatment with CRAd or VPA alone...

Tumor-associated fibroblasts (TAFs) are often essential for solid tumor growth. However, few genetic or epigenetic alterations have been found in TAFs during the progression of solid tumors. Employing a tumor-stromal cell co-injection model, we adapted here retroviral-insertional mutagenesis to stromal cells to identify novel tumor-associated genes in TAFs. We successfully identified 20 gene candidates that might modulate tumor growth if altered in TAFs at genomic level. To validate our finding, the function of one of the candidate genes, tubulin tyrosine ligase (Ttl), was further studied in TAFs from fibrosarcoma, colon, breast and hepatocarcinoma...

Sirt family has been reported playing a significant role in the cancer develop, special its deacetylase activity plays a key function, but whether SIRT6 plays a role in mediating tumor EMT and metastasis in colon cancer has not been explored. Here, the mass spectrometry and co-immunoprecipitation assays were utilized to detect that SIRT6 was physically associated with transcription factor snail. Most important, HCT116 cells transfected with SIRT6 shRNA reversed EMT, while increased the expression of TET1, and the HCT116 cells transfected with SIRT6 displayed the contrary tendency...

For a patient with metastatic colorectal cancer there are limited clinical options aside from chemotherapy. Unfortunately, the development of new chemotherapeutics is a long and costly process. New methods are needed to identify promising drug candidates earlier in the drug development process. Most chemotherapies are administered to patients in combinations. Here, an in vitro platform is used to assess the penetration and metabolism of combination chemotherapies in three-dimensional colon cancer cell cultures, or spheroids...

Transcription factors (TFs) and microRNAs (miRNAs) regulate gene expression: TFs by influencing messenger RNA (mRNA) transcription and miRNAs by influencing mRNA translation and transcript degradation. Additionally, miRNAs and TFs alter each other's expression, making it difficult to ascertain the effect either one has on target gene (TG) expression. In this investigation, we use a two-way interaction model with the TF and miRNA as independent variables to investigate whether miRNAs and TFs work together to influence TG expression levels in colon cancer subjects...

Curcumin exhibits anti-tumor effects in several cancers, including colorectal carcinoma (CRC), but the detailed mechanisms are still unclear. Here we studied the mechanisms underlying the anti-tumor effect of curcumin in colon cancer cells. SW480 cells were injected into mice to establish the xenograft tumor model, followed by evaluation of survival rate with the treatment of curcumin. The expression levels of β-catenin, Axin and TCF4 were measured in the SW480 cells in the absence or presence of curcumin...

BACKGROUND: A pivotal role of sphingosine 1-phosphate (S1P) in cancer has been suggested based on the ceramide-S1P rheostat theory that the intracellular balance between prosurvival S1P and proapoptotic ceramide determines cell fate. Upregulation of S1P-generating sphingosine kinases (SKs) and downregulation of S1P-degrading S1P lyase (SPL) might increase intracellular S1P levels to exert a prosurvival effect in cancer in general, such as colon cancer. However, we recently observed a distinct S1P metabolism in hepatocellular carcinoma tissues that increased SPL mRNA levels with reduced S1P levels...

Aberrant crypt foci (ACF) are the earliest morphologically identifiable lesion found within the human colon. Despite their relatively high frequency in the distal colon, few studies have examined the molecular characteristics of ACF within the proximal colon. In the following study, clinical participants (n=184) were screened for ACF using high-definition chromoendoscopy with contrast dye-spray. Following pathological confirmation, ACF biopsies were subjected to laser-capture microdissection (LCM) and epithelial cells were evaluated for somatic mutations with a customized colorectal cancer mutation panel using DNA-mass spectrometry...

Helicobacter pylori (H. pylori) contributes to various gastric diseases such as chronic gastritis, gastric ulcer, and gastric carcinoma. Host innate immune response against the pathogen plays a significant role in elimination of pathogen infection. Importantly, pathogen elimination is closely related to numerous inflammatory-related genes that participate in complex biological response of cells to harmful stimuli. Here we studied effects of the KH-type splicing regulatory protein (KSRP), a RNA-binding protein, on innate immune response against H...
