REVIEW
Assaf A Gilad, Mikhail G Shapiro
Biomedical synthetic biology is an emerging field in which cells are engineered at the genetic level to carry out novel functions with relevance to biomedical and industrial applications. This approach promises new treatments, imaging tools, and diagnostics for diseases ranging from gastrointestinal inflammatory syndromes to cancer, diabetes, and neurodegeneration. As these cellular technologies undergo pre-clinical and clinical development, it is becoming essential to monitor their location and function in vivo, necessitating appropriate molecular imaging strategies, and therefore, we have created an interest group within the World Molecular Imaging Society focusing on synthetic biology and reporter gene technologies...

An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification)...

BACKGROUND: The increasing use of laparoscopic surgery for advanced gastrointestinal cancer raises concerns about intra-peritoneal tumor spread. Prevention of peritoneal dissemination is extremely important but a preventive modality is lacking. The aim of this study was to examine a novel approach (hyperthermic CO2 insufflation, HT-CO2) for preventing peritoneal dissemination during laparoscopic surgery. METHODS: A peritoneal dissemination model was established in Balb/c nu/nu mice by intraperitoneal injection of human colon cancer cells (SW1116, 1×106)...

Nutrient-sensing receptors, including fatty acid receptors (FFA1-FFA4), Ca(2+)-sensing receptors and Zn(2+)-sensing receptors, are involved in several biological processes. These receptors are abundantly expressed in the GI tract, where they have been shown to play crucial roles in regulating GI function. This review provides an overview of the GI functions of fatty acid and mineral receptors, including the regulation of gastric and enteroendocrine functions, GI motility, ion transport and cell growth. Recently, several lines of evidence have implicated these receptors as promising therapeutic targets for the treatment of GI disorders, for example, inflammatory bowel disease, colorectal cancer, metabolic syndrome and diarrheal diseases...

Many studies have showed that routine upper gastrointestinal contrast agent examinations (RCE) for testing the patency of the anastomosis after esophagectomy or the stapler line after sleeve gastrectomy cannot be recommended due to low sensitivity. However, the clinical value of RCE after gastrectomy for gastric cancer remains unclear. We have retrospectively analyzed the clinical course of 377 consecutive patients who underwent gastrectomy for gastric cancer in our institution between 2005 and 2015. To date, we have performed a RCE on the fifth postoperative day before removal of the nasogastric tube and return to oral intake...

Gastrointestinal perforation is a serious adverse event that occurs in approximately 1% of patients receiving ramucirumab and paclitaxel. A 67-year-old man with unresectable advanced gastric cancer was admitted to our hospital and treated with ramucirumab and paclitaxel. Gastric perforation occurred during the second cycle of chemotherapy. Although the patient's condition improved without surgery, an abscess developed in the intra-abdominal fluid collection resulting from the perforation. We performed endoscopic ultrasound-guided abscess drainage...

Tumor cell metabolism is a promising target for various cancer treatments. Apart from aerobic glycolysis, cancer cell growth is dependent on glutamine (Gln) supply, leading to their survival and differentiation. Therefore, we examined whether treatment with TNF-related apoptosis-inducing ligand (TRAIL) sensitizes MDA-MB-231 cells to apoptosis under Gln deprivation condition (TRAIL/Gln deprivation). Gln deprivation decreased cell proliferation as expected, but did not induce remarkable cell death. TRAIL/Gln deprivation, however, significantly increased growth inhibition and morphological shrinkage of MDA-MB-231 cells compared to those induced by treatment with either Gln deprivation or TRAIL alone...

Vitamin D has been widely used as a dietary supplement for the prevention and treatment of bone disorders. Epidemiological and preclinical studies demonstrated the anticancer action of vitamin D in a variety of cancers including those in the gastrointestinal (GI) tract. In these studies the inhibitory action of vitamin D on cancer stem cells (CSCs) has been a focus and is also an important subject to revolutionize the therapeutic potential of vitamin D on cancer treatment. Here, we summarize the involvement of CSC markers and factors and also their signaling pathways in the development of cancers in the esophagus, stomach, colon, pancreas and also liver...

BACKGROUND & AIMS: There is high need of novel diagnostic and prognostic tools for tumors of the digestive system, such as gastric cancer and cholangiocarcinoma. We recently found that miR-204 was deeply downregulated in gastric cancer tissues. Here we investigated whether this was common to other tumors of the digestive system and whether this elicited a miR-204-dependent gene target signature, diagnostically and therapeutically relevant. Finally, we assessed the contribution of the identified target genes to the cell cycle progression and clonogenicity of gastric cancer and cholangiocarcinoma cell lines...

BACKGROUND: An accurate diagnosis of cancer of Müllerian origin is required before the initiation of treatment. An overlap in clinical presentation and cytological, histological, or imaging studies with other nongynecological tumors does occur. Therefore, immunocytochemistry markers are used to determine tumor origin. Human epididymis protein 4 (HE4) is overexpressed in tissue of epithelial ovarian cancer (EOC). It has shown to be a sensitive and specific serum marker for EOC and to be of value for the differentiation between EOC and ovarian metastases of gastrointestinal origin...

BACKGROUND AND OBJECTIVES: Red blood cell (RBC) transfusion may be justified in iron deficiency anaemia (IDA) when an increase in oxygen delivery is needed, as sometimes occurs in subjects with haemoglobin <8·0 mg/dL, serious comorbidities or at risk of cardiovascular instability. Earlier investigations showed that some patients with severe IDA requiring transfusion had lower than expected post-transfusion haemoglobin levels with poorer clinical outcomes than other patients. After hypothesizing that haemoglobin responses to transfusion were different and that the underlying gastrointestinal (GI) disorders causing IDA could be a confounder explaining this association, these responses were analysed in a prospective cohort of IDA adults referred for outpatient GI investigation...

RBJ has been identified to be dysregulated in gastrointestinal cancer and promotes tumorigenesis and progression by mediating nuclear accumulation of active MEK1/2 and sustained activation of ERK1/2. Considering that nuclear accumulation and constitutive activation of MEK/ERK not only promotes tumor progression directly, but also induces chronic inflammation, we wonder whether and how RBJ impairs host immune-surveillance via chronic inflammation and consequently supports tumor progression. Here, we report that higher expression of RBJ in human breast cancer tissue has been significantly correlated with poorer prognosis in breast cancer patients...

The putative contribution of natural killer (NK) cells to immunosurveillance in non-small cell lung cancer (NSCLC) has been an ongoing conundrum. Here, we used a readily standardizable quantitative real time polymerase chain reaction (qRT-PCR) to measure the expression of NK cell receptors in total peripheral blood mononuclear cells (PBMC) from healthy volunteers (HV), patients with gastrointestinal stromal tumors (GIST), neuroblastoma (NB), melanoma or NSCLC. We quantified NCR1 (which codes for NKp46) and NCR3 (which codes for NKp30), as well as that of three NCR3 splice variants (which give rise to immunostimulatory NKp30A and NKp30B, as well as to immunosuppressive NKp30C)...

Glycaemic index (GI) and glycaemic load (GL) are indicators of dietary carbohydrate quantity and quality and have been associated with increased risk of certain cancers and type 2 diabetes. Insulin resistance has been associated with increased melanoma risk. However, GI and GL have not been investigated for melanoma. We present the first study to examine the possible association of GI and GL with melanoma risk. We carried out a population-based, case-control study involving 380 incident cases of cutaneous melanoma and 719 age- and sex-matched controls in a northern Italian region...
