Diet and colon: what matters?

Purpose of review Colorectal cancer (CRC) is one of the most common cancers and the fourth leading cause of cancer-related deaths worldwide. Diet has a significant impact on the risk of developing CRC, but though processed meat is a known positive contributor, the effects of other dietary components are largely mixed. This review focuses on dietary patterns to describe the complexity of dietary diversity and overall food consumption and to examine the relationship between dietary patterns and risk of CRC. Recent findings After searching human studies published in 2017–2018, we selected and evaluated 30 articles, including meta-analyses, cohort studies, and prospective studies. These studies suggest that the prudent or Mediterranean dietary pattern significantly decreases the risk of CRC compared to the Western dietary pattern; a lower dietary inflammatory index or a higher dietary quality index associates with a lower risk of CRC; closely following all aspects of the World Cancer Research Fund/American Institute for Cancer Research cancer prevention guidelines and recommendations correlates with a reduced risk of CRC. Summary The risk of developing CRC can be reduced by adopting a healthier lifestyle. More studies of the impact of diet on clinical outcomes of CRC are needed.

Gastric cancer remains one of the most common cancers worldwide and is the third leading cause of cancer-related mortality, trailing only lung and colon cancer.1 Given its historically low survival rates, early detection and resection is the most effective strategy to improve prognosis. Endoscopic submucosal dissection (ESD), a technique developed in Japan, enables en bloc resection of early gastric cancer (EGC) and can be curative for selected lesions, depending on the histologic features, size, and tumor depth.

This study aims to investigate the antiproliferative activity and potential mechanism of action of the xanthoquinodin JBIR-99, isolated from fungi Parengyodontium album MEXU 30,054 and identified by single-crystal X-ray crystallography. Cytotoxicity of xanthoquinodin was evaluated in a panel of human cancer cells lines and CCD-112-CoN normal colon cells, using the sulforhodamine B assay. PC-3 prostate cancer cells were used in biochemical assays including cell cycle, mitochondrial transmembrane potential (MTP), reactive oxygen species (ROS) and caspase activity. Expression levels of apoptosis-pathway-related proteins were ...

In conclusion, our data show how oncogenic and tumor-suppressive drivers of cellular senescence act to regulate surveillance processes that can be circumvented to enable SnCs to elude immune recognition but can be reversed by cell surface-targeted interventions to purge the SnCs that persist in vitro and in patients. Since eliminating SnCs can prevent tumor progression, delay the onset of degenerative diseases, and restore fitness; since NKG2D-Ls are not widely expressed in healthy human tissues and NKG2D-L shedding is an evasion mechanism also employed by tumor cells; and since increasing numbers of B cells express NKG2D ...

AbstractMFAP5, a 25-kD microfibril-associated glycoprotein that is involved in elastic microfibril assembly, has been demonstrated to be significantly downregulated in tumor stroma by previous gene expression study. The aim of this study was to confirm the reduced expression of MFAP5 in colonic tumor stroma using immunohistochemistry and to explore the utility of MFAP5 as a marker to facilitate diagnosing an invasive component versus pseudoinvasion in colon polyps. In all 19 colon cancer resection cases evaluated, while there was intact MFAP5 immunoreactivity in the uninvolved normal connective tissue, there was marked red...

This population-based study aimed to compare survival among non-metastatic CRC patients between age groups and notice time trends in mortality rates.MethodsPrimary stage I-III CRC patients who underwent resection between 2008 and 2013 were selected from the Netherlands Ca...

In this study, we identified a cluster of DNA repair-related proteins that interact with ALDOB in the colon adenocarcinoma cell line HCT116. Expression analysis of colon adenocarcinoma data from the Cancer Genome Atlas (TCGA-COAD data, n = 551) indicated that ALDOB mRNA expression was significantly higher in specimens with microsatellite instability (MSI) than in specimens with microsatellite stability (MSS). Regarding prognosis, colon adenocarcinoma patients with high ALDOB mRNA expression had longer overall survival (OS). Higher expression of ALDOB protein was significantly correlated with MMR deficiency (d-MMR) in forma...

Retinoblastoma binding protein 6 (RBBP6) is a cancer-related protein that has been implicated in the regulation of cell cycle and apoptosis. RBBP6 isoform 1 has been demonstrated to interact with two tumour suppressors, p53 and pRB. Isoform 1 been shown to regulate p53 through its ubiquitin ligase activity, thus implicating in cell cycle regulation and apoptosis. Isoforms 1 and 2 are multidomain proteins containing a domain with no name (DWNN) domain, a Zinc Finger, a RING Finger, an Rb-binding domain and a p53-binding domain. The RBBP6 isoform 3 comprises the DWNN domain only. Isoform 4 lacks the Rb-binding domain but its...

By STEVEN MERAHN, MD In 1807, in an effort to spite the British and French for shipping interference (and forced recruitment of American citizens into military service), the United States Congress passed an Embargo Act, effectively shutting down trade with these two countries. Britain and France quickly found other trading partners; the US, then limited in our capacity to sell products outside our borders, was left with a devastated economy and a gaping hole in our face. It took only weeks before Congress passed a loophole; they repealed the act within 15 months of its passing. It was a great lesson in unintended co...

In this study, we provide both correlative and functional evidence that senescent fibroblasts and an essential SASP factor, GDF15, induce physiological and molecular changes that promote the adenoma-carcinoma initiation and progression sequence in the colon. We assessed the role of senescence and the SASP in CRC formation. Using primary human colon tissue, we found an accumulation of senescent fibroblasts in normal tissues from individuals with advanced adenomas or carcinomas in comparison with individuals with no polyps or CRC. In in vitro and ex vivo model systems, we induced senescence using oxidative stress in c...
