Cancers, Vol. 12, Pages 274: Cancer Stem Cell Marker DCLK1 Correlates with Tumorigenic Immune Infiltrates in the Colon and Gastric Adenocarcinoma Microenvironments

In conclusion, our results demonstrate that DCLK1 is linked with functional regulation of the tumor microenvironment and may have potential as a prognostic biomarker and adjuvant target to promote immunotherapy sensitivity in colon and gastric cancer patients.

Conclusions Lynch syndrome should be suspected in families with familial pancreatic cancer, even in the absence of colon cancers. Specifically, our observation supports the association between the MSH6 c.2194C>T pathogenic variant and extracolonic tumours and it suggests that MSH6 pathogenic variants are associated with familial pancreatic cancer more frequently than assumed.

Abstract Many studies have shown that TP53 mutations play a negative role in antitumor immunity. However, a few studies reported that TP53 mutations could promote antitumor immunity. To explain these contradictory findings, we analyzed five cancer cohorts from The Cancer Genome Atlas (TCGA) project. We found that TP53-mutated cancers had significantly higher levels of antitumor immune signatures than TP53-wildtype cancers in breast invasive carcinoma (BRCA) and lung adenocarcinoma (LUAD). In contrast, TP53-mutated cancers had significantly lower antitumor immune signature levels than TP53-wildtype cancers in stoma...

Abstract In their seminal papers Hanahan and Weinberg described oncogenic processes a normal cell undergoes to be transformed into a cancer cell. The functions of ion channels in the gastrointestinal (GI) tract influence a variety of cellular processes, many of which overlap with these hallmarks of cancer. In this review we focus on the roles of the calcium (Ca2+), sodium (Na+), potassium (K+), chloride (Cl-) and zinc (Zn2+) transporters in GI cancer, with a special emphasis on the roles of the KCNQ1 K+ channel and CFTR Cl- channel in colorectal cancer (CRC). Ca2+ is a ubiquitous second messenger, serving as a sig...

Sialyl Lewis A (sLeA, also known as CA19-9), a tetrasaccharide selectively and highly expressed on advanced adenocarcinomas including colon, stomach, and pancreatic cancers, has long been considered as an attractive target for active and passive vaccination. While progress in antibodies targeting tumor-associated protein antigens resulted in an impressive array of therapeutics for cancer treatment, similar progress in exploiting tumor-associated carbohydrate antigens, such as sLeA, has been hampered by the lack of a detailed understanding of the singular characteristics of these antigens. We have addressed this issue by an...

Authors: Baek SH, Lee JH, Yoo DR, Kim HY, Jin M, Jang AR, Yang DH, Byeon JS Abstract Colon interposition is a surgical procedure used for maintenance of luminal conduit after esophagectomy. Although epithelial neoplasia, such as adenoma and adenocarcinoma, may develop in the interposed colon, there are only few case reports on the condition. Due to the rarity of this condition, there is no definite consensus on recommending screening endoscopy for the early detection of neoplasia in the interposed colons. Here, we report a case of intramucosal adenocarcinoma in an interposed colon. Initial endoscopic resection for ...

Chronic inflammation takes part in the pathogenesis of some malignancies of the gastrointestinal tract including colorectal (CRC), gastric and esophageal cancers. The use of ω3 polyunsaturated fatty acids (ω3-PUFAs) supplements for chemoprevention or adjuvant therapy of gastrointestinal cancers is being investigated in the recent years. Most evidences have been reported in CRC, although their protective role has also been reported for Helicobacter pylori-induced gastric cancer or Barrett’s esophagus-derived adenocarcinoma. Studies based on ω3-PUFAs supplementation in animal models of familial adenom...
