Magnesium status and supplementation influence vitamin D status and metabolism: results from a randomized trial.

Am J Clin Nutr 2018 Dec;108(6):1249-1258

Division of Epidemiology, Department of Medicine, Vanderbilt Epidemiology Center, School of Medicine, Vanderbilt University, Vanderbilt-Ingram Cancer Center, Vanderbilt University Medical Center, Nashville, TN.

Background: Previous in vitro and in vivo studies indicate that enzymes that synthesize and metabolize vitamin D are magnesium dependent. Recent observational studies found that magnesium intake significantly interacted with vitamin D in relation to vitamin D status and risk of mortality. According to NHANES, 79% of US adults do not meet their Recommended Dietary Allowance of magnesium. Read More

Caspase-11 regulates the tumour suppressor function of STAT1 in a murine model of colitis-associated carcinogenesis.

Oncogene 2018 Dec 11. Epub 2018 Dec 11.

Trinity Biomedical Sciences Institute, School of Biochemistry & Immunology, Trinity College Dublin, Dublin 2, Ireland.

Murine inflammatory caspase-11 has an important role in intestinal epithelial inflammation and barrier function. Activation of the non-canonical inflammasome, mediated by caspase-11, serves as a regulatory pathway for the production of the pro-inflammatory cytokines IL-1β and IL-18, and has a key role in pyroptotic cell death. We have previously demonstrated a protective role for caspase-11 during dextran sulphate sodium (DSS)-induced colitis, however the importance of caspase-11 during colorectal tumour development remains unclear.

Portal vein embolization DOES not AFFECT the long-term survival and risk of cancer recurrence among colorectal liver metastases patients: A prospective cohort study.

Int J Surg 2018 Dec 8. Epub 2018 Dec 8.

Service de chirurgie hépatobiliaire et pancréatique et de transplantation, Département de chirurgie, Centre Hospitalier de l'Université de Montréal, Site St-Luc, Montréal, QC, Canada.

Background: Previous studies comparing the survival outcomes of liver resections with and without preoperative portal vein embolization (PVE) for colorectal liver metastases (CLM) have linked PVE to higher rate of tumor progression, lower overall survival (OS) and lower disease-free survival (DFS). The lack of adjusted models to compare these outcomes is a limitation of these studies since patients requiring PVE may differ significantly from the ones receiving upfront surgery.

Materials And Methods: Prospective cohort study of 128 patients undergoing CLM resection. Read More

Immunodivergence in Metastatic Colorectal Cancer.

Cancer Cell 2018 Dec;34(6):876-878

Clinica Universidad de Navarra, Pamplona, Spain; CIBERONC, Madrid, Spain; Center for applied Medical Research (CIMA), Pamplona, Spain; IDISNA, Pamplona, Spain. Electronic address:

Van den Eynde et al. publish in this issue of Cancer Cell that metastatic colorectal cancer shows marked heterogeneity in T cell infiltration among different lesions and patients. Measurements of T cell infiltration in metastases by immunoscore offer some prognostic information and support immune editing by coevolving adaptive immune responses. Read More

The Link between the Multiverse of Immune Microenvironments in Metastases and the Survival of Colorectal Cancer Patients.

Cancer Cell 2018 Dec;34(6):1012-1026.e3

INSERM, Laboratory of Integrative Cancer Immunology, Sorbonne Université, Sorbonne Paris Cité, Université Paris Descartes, Université Paris Diderot; Centre de Recherche des Cordeliers, 75006 Paris, France. Electronic address:

Treatment of metastatic colorectal cancer is based upon the assumption that metastases are homogeneous within a patient. We quantified immune cell types of 603 whole-slide metastases and primary colorectal tumors from 222 patients. Primary lesions, and synchronous and metachronous metastases, had a heterogeneous immune infiltrate and mutational diversity. Read More

Acute lower gastrointestinal bleeding: are STRATE and BLEED scores valid in clinical practice?

Colorectal Dis 2018 Dec 7. Epub 2018 Dec 7.

Hospital Senhora da Oliveira, Gastrenterology Department - Guimarães, Portugal.

Aim: Acute lower gastrointestinal bleeding (ALGIB) is a commongastroenterological emergency. Despite this outcomes are difficult to predict Onlyy STRATE and BLEED scores are readily available. The aim of this study was to identify risk factors for severe ALGIB and access the validity of available scores. Read More

Ginseng metabolite protopanaxadiol interferes with lipid metabolism and induces endoplasmic reticulum stress and p53 activation to promote cancer cell death.

Phytother Res 2018 Dec 9. Epub 2018 Dec 9.

The Ben May Department for Cancer Research, University of Chicago, Chicago, Illinois, USA.

Protopanaxadiol (PPD), a ginseng metabolite generated by the gut bacteria, was shown to induce colorectal cancer cell death and enhance the anticancer effect of chemotherapeutic agent 5-FU. However, the mechanism by which PPD promotes cancer cell death is not clear. In this manuscript, we showed that PPD activated p53 and endoplasmic reticulum (ER) stress and induced expression of BH3-only proteins Puma and Noxa to promote cell death. Read More

Long noncoding RNA ABHD11-AS1 promote cells proliferation and invasion of colorectal cancer via regulating the miR-1254-WNT11 pathway.

J Cell Physiol 2018 Dec 7. Epub 2018 Dec 7.

Department of General Surgery, The First Affiliated Hospital of Xinxiang Medical University, Weihui, Henan, China.

The purpose of our study was to investigate the effects of the long noncoding RNA (lncRNA) ABHD11-AS1 on colorectal cancer (CRC) progression and further explore its possible underlying mechanisms. In the study, we found that ABHD11-AS1 was highly expressed in CRC tissues and cell lines. High ABHD11-AS1 expression was correlated with poor overall survival of patients with CRC. Read More
