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 ...

In this study, Lactobacillus plantarum (L. plantarum) KLDS1.0318 preserved in our laboratory was orally administered to CTX-treated mice to explore its potential effects to attenuate the toxic effects of CTX-induced by modulating intestinal immune response, promoting intestinal integrity and improving metabolic profile. BALB/c mice were randomly divided into six groups including normal control group (NC; non-CTX with sterile saline), model control group (MC; CTX-treated with sterile saline), CTX-treated with L. plantarum KLDS1.0318 (10 mL/kg) groups with three different doses (KLDS1.0318-L, 5 × 107 CFU/mL; KLDS1.0318...

Conclusions The current review reports recent epidemiological and experimental data supporting the bright future of dietary polyphenols as chemopreventive, anti-inflammatory, immunomodulatory, and anticancer agents in CRC (Figure 1). The polyphenol-rich diet not only may represent a chemopreventive treatment but also has important function on immune system by promoting symbiont and commensal bacterial populations, increases reciprocal interaction between host and microbiota which in turn have important effects on immune function Evidence underlines the use of polyphenols as sensitizers of chemo/radiotherapies paving the w...

Conclusion: Prognosis prediction based on informative DEGs might yield a higher predictive accuracy in CRC prognosis than the TNM staging system does. Introduction Colorectal Cancer (CRC) is one of the most common malignancies globally (1). In order to guide clinical treatment and predict prognosis, several CRC staging systems have been established, especially the American Joint committee on Cancer (AJCC) tumor-node-metastasis (TNM) system based on anatomical information, which is widely used (2). According to the TNM staging system, the survival of CRC patients is related to the size of primary tumor (T), nearby lym...

Authors: Kim K, Castro EJT, Shim H, Advincula JVG, Kim YW Abstract For many years, developmental and physiological differences have been known to exist between anatomic segments of the colorectum. Because of different outcomes, prognoses, and clinical responses to chemotherapy, the distinction between right colon cancer (RCC) and left colon cancer (LCC) has gained attention. Furthermore, variations in the molecular features and gut microbiota between right and LCCs have recently been a hot research topic. CpG island methylator phenotype-high, microsatellite instability-high colorectal cancers are more likely to occ...

C. elegans, fed a diet of E. coli bacteria, are 100 times more sensitive to the chemotherapy drug floxuridine, commonly used to treat colon cancer, than worms fed different bacteria. These findings suggest that the bacteria residing in your digestive tract may play an important role in your ability to respond to chemotherapy.

Abstract We evaluated supernatants (SNs) from Escherichia coli Nissle 1917 (EcN) grown in commonly used growth media for their capacity to affect the viability of Caco-2 colon cancer cells in the presence and absence of 5-Fluorouracil (5-FU) chemotherapy. EcN was grown in Luria-Bertani (LB), tryptone soya (TSB), Man Rogosa Sharpe (MRS), and M17 broth supplemented with 10% (v/v) lactose solution (M17). Human Caco-2 colon cancer cells were treated with DMEM (control), growth media alone (LB, TSB, MRS, and M17) or EcN SNs derived from these 4 media, in the presence and absence of 5-FU. Cell viability, reactive oxygen...
