Background: To establish one primary cell line of human liver metastasis of colon cancer. Methods: HCS1220 cell line was derived from one liver metastasis of colon cancer patient's resected tumor sample. The characterization of the cell line was defined by karyotype analysis, short tandem repeat (STR) analysis and mycoplasma contamination. Subcutaneous injection 1 × 106  cells to four BALB/c nude mice, the viable tumors were developed and diagnosed (H&E staining)...

A 43-year-old man presented with two-month history of fatigue, weakness, paleness, rectal bleeding, sweating, and weight loss of 10 kg in the past one month. A complete blood count revealed anaemia. The patient underwent a right hemicolectomy. The microscopic examination revealed an adenosquamous carcinoma associated with a mucinous adenocarcinoma in a patient with microsatellite instability due to loss of MLH1 and PMS2 expression and retention of MSH2 and MSH6 expression in both the squamous and glandular components...

Colorectal cancers (CRCs) harbor accumulated defects in key signaling pathways that regulate cell phenotypes, including proliferation, survival, metabolism, and differentiation. To study the functional contributions of the accumulated molecular defects in CRC, we have developed approaches to inactivate selected tumor suppressor and/or activate oncogenes in mouse colon epithelium. Conditional inactivation of the CDX2 tumor suppressor protein in conjunction with oncogenic activation of the BRAF protein promotes development of serrated glandular benign and malignant tumors in the mouse colon...

Although pancreatic and gastric heterotopias are common findings in the gastrointestinal tract, heterotopic respiratory mucosa (HRM) in the rectum is extremely rare and has only been reported twice previously. We are presenting, to our knowledge, the third case of HRM in the rectum. A 56-year-old man with a history of chronic diarrhea presented for diagnostic colonoscopy, where he was found to have a rectal subepithelial nodule. He was subsequently referred to a tertiary medical center for further evaluation with rectal endoscopic ultrasound...

Colonic metastasis from lung cancer is rare, generally asymptomatic and usually develop at advanced cancer stages. Here, we report a case with a resected stage IA lung adenocarcinoma in a 51yo male patient that presented two years later with mild abdominal pain due to intestinal obstruction caused by a metastatic colon tumor. The patient underwent colonoscopy followed by surgical resection and the pathologic report was adenocarcinoma which was the same as that from a lung nodule that was excised two years earlier...

Lynch syndrome (LS) patients with isolated PMS2 loss in the colon cancer, while intact MMR in the prostate cancer, are exceedingly rare. Herein, we report such a case. A 71-year-old male was found to have increased serum PSA (10 ng/ml) after treatment for his urinary tract infection. Prostate biopsies showed foci of prostate cancer with Gleason score 7 (3+4) (grade grope 2) involving 10% of two cores. Through work up for treatment of the prostate cancer, he was found to have focal thickening of his sigmoid colon with adjacent lymphadenopathy in CT scans...

Sequencing of primary colorectal tumors has identified a gene fusion in approximately 3% of colorectal cancer patients of the VTI1A and TCF7L2 genes, encoding a VTI1A-TCF4 fusion protein containing a truncated TCF4. As dysregulation of the Wnt signaling pathway is associated with colorectal cancer development and progression, the functional properties and transcriptional regulation of the VTI1A-TCF4 fusion protein may also play a role in these processes. Functional characteristics of the VTI1A-TCF4 fusion protein in Wnt signaling were analyzed in NCI-H508 and LS174T colon cancer cell lines...

Intestinal-type adenocarcinoma of the primary salivary glands is extremely rare. So far, only 11 cases of primary intestinal-type adenocarcinoma of the oral cavity and major salivary glands have been reported. Two of those tumors arose in the floor of mouth, 7 in the tongue, and 2 in the major salivary glands. However, it has remained unclear whether these tumors are derived from mature salivary glands, and primary intestinal-type adenocarcinoma of the buccal mucosa has not been reported previously. Here, we present the first documented case of primary intestinal-type adenocarcinoma arising in a minor salivary gland of the buccal mucosa...

CDX2 is routinely used for identifying gastrointestinal origin of metastatic adenocarcinomas; but a high percentage of other carcinomas also show positivity with this antibody. SATB2 is a new immunohistochemical marker with a few studies showing that it is specifically expressed in a large majority of colorectal adenocarcinomas. We assessed SATB2 along with CDX2 in patient material with metastasis in order to determine whether the primary site could be identified as 'colon-rectum'. Metastasis in 67 liver biopsies, 108 lymph nodes from resection specimens and 36 serous effusions was analyzed retrospectively...

Colorectal cancer (CRC) is the second most frequent and fatal cancer in Western countries. Understanding its biology with different incidence along the colon and rectum, genetic profile and how these factors contribute to local/distant progression, has been hampered by the lack of a suitable CRC model. We report a reproducible model, using human CRC cell lines (CL) (WiDr, LS1034, C2BBe1) injected (1 × 107 cells/animal) in RNU rats (n = 55) which underwent cecostomy and descending colostomy with mucosal-cutaneous fistula of the sigmoid colon...

The gastrointestinal tract expresses several UDP-glucuronosyltransferases (UGTs) that act as a first line of defense against dietary toxins and contribute to the metabolism of orally administered drugs. The expression of UGT1A8 , UGT1A9 , and UGT1A10 in gastrointestinal tissues is known to be at least partly directed by the caudal homeodomain transcription factor, CDX2. We sought to further define the factors involved in regulation of the UGT1A8-1A10 genes and identified a novel composite element located within the proximal promoters of these three genes that binds to both CDX2 and the hepatocyte nuclear factor (HNF) 4 α , and mediates synergistic activation by these factors...

LRP1 (low-density lipoprotein receptor-related protein 1), a multifunctional endocytic receptor, has recently been identified as a hub within a biomarker network for multi-cancer clinical outcome prediction. As its role in colon cancer has not yet been characterized, we here investigate the relationship between LRP1 and outcome. Materials and Methods: LRP1 mRNA expression was determined in colon adenocarcinoma and paired colon mucosa samples, as well as in stromal and tumor cells obtained after laser capture microdissection...

INTRODUCTION: Metastatic carcinoma of the colon is frequently encountered. In the literature, metastasis of malignant tumors in the buccal cavity are rare. They represent less than 1% of oral malignant lesions. OBSERVATION: We present a case of oral metastasis of colon adenocarcinoma in the mandible of a 62-year-old patient. The physical examination revealed a swelling in the mandibular symphysis associated with dental displacement. The panoramic X-ray showed significant bone lysis of the symphysis...

BACKGROUND: Primary intestinal-type adenocarcinoma of the tongue is rare. This represents the first reported case of a primary mixed adenoneuroendocrine carcinoma (MANEC) of the tongue arising within a congenital enteric cyst. METHODS: A 52-year-old man presented with a midline tongue mass that was connected to the mucosal surface with an epithelial-lined sinus tract. Morphological examination and immunohistochemical profiling of the neoplasm were performed. RESULTS: Histopathological evaluation showed a primary MANEC arising within a preexisting congenital enteric cyst, comprising both adenocarcinoma and neuroendocrine components...

Oncogenic mutations in BRAF are believed to initiate serrated colorectal cancers; however, the mechanisms of BRAF-driven colon cancer are unclear. We find that oncogenic BRAF paradoxically suppresses stem cell renewal and instead promotes differentiation. Correspondingly, tumor formation is inefficient in BRAF-driven mouse models of colon cancer. By reducing levels of differentiation via genetic manipulation of either of two distinct differentiation-promoting factors (Smad4 or Cdx2), stem cell activity is restored in BRAFV600E intestines, and the oncogenic capacity of BRAFV600E is amplified...

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...

Recent studies show that colonic vitamin D receptor (VDR) signaling protects the mucosal epithelial barrier and suppresses colonic inflammation, but the underlying molecular mechanism remains to be fully understood. To investigate the implication of colonic VDR downregulation seen in patients with inflammatory bowel disease, we assessed the effect of gut epithelial VDR deletion on colonic inflammatory responses in an experimental colitis model. In a 2,4,6-trinitrobenzenesulfonic acid-induced colitis model, mice carrying VDR deletion in gut epithelial cells [VDRflox/flox (VDRf/f);Villin-Cre or VDRΔIEC] or in colonic epithelial cells (VDRf/f;CDX2-Cre or VDRΔCEC) developed more severe clinical colitis than VDRf/f control mice, characterized by more robust T-helper (TH)1 and TH17 responses, with greater increases in mucosal interferon (IFN)-γ+, interleukin (IL)-17+, and IFN-γ+IL-17+ T cells...

AIMS: Hepatic progenitor cells (HPCs) are activated in various liver diseases, but their role in the carcinomatous environment remains unknown. We aimed to identify the possible presence and topography of HPCs in liver metastases. METHODS AND RESULTS: We examined 14 liver resection specimens for colorectal adenocarcinoma (n = 13) and anal squamous cell carcinoma (n = 1) metastases. Immunohistochemical markers of colonic origin (keratin 20 and CDX2) and squamous cell origin (p63), HPC [keratin 19 (K19) and CD56] and stem cell (CD44) markers, and the biliary marker keratin 7 (K7), which may also highlight HPCs, were applied on routinely processed tissue sections...

Dysregulation of microRNAs (miRNAs) has been linked to virulence factors of Helicobacter pylori. The role of H. pylori in esophageal disease has not been clearly defined. We previously reported that H. pylori esophageal colonization promotes the incidence of Barrett's esophagus and esophageal adenocarcinoma in vivo. Here, we studied the direct effects of H. pylori on the transformation of esophageal epithelial cells, with particular focus on whether H. pylori exerts its effects by modulating miRNAs and their downstream target genes...

Phenotypic conversion of tumor cells through epithelial-mesenchymal transition (EMT) requires massive gene expression changes. How these are brought about is not clear. Here we examined the impact of the EMT master regulator SNAIL1 on the FOXA family of transcription factors which are distinguished by their particular competence to induce chromatin reorganization for the activation of transcriptional enhancer elements. We show that the expression of SNAIL1 and FOXA genes is anticorrelated in transcriptomes of colorectal tumors and cell lines...
