BACKGROUND: Recent data suggest that intensity-modulated radiation therapy (IMRT) plus brachytherapy boost for unfavorable prostate cancer provides improved biochemical relapse-free survival over IMRT alone. Stereotactic body radiation therapy (SBRT) may be a less invasive alternative to brachytherapy boost. Here, we report the 3-year gastrointestinal (GI) and genitourinary (GU) toxicities of IMRT plus SBRT boost. MATERIALS AND METHODS: Between March 2008 and September 2012, patients with prostate cancer were treated with robotic SBRT (19...

Until the 1990s, cytotoxic chemotherapy has been the cornerstone of medical therapy for gastrointestinal (GI) cancers. Better understanding of the molecular biology of cancer cell has led to the therapeutic revolution of targeted therapies, i.e. monoclonal antibodies or small molecule inhibitors directed against proteins that are specifically overexpressed or mutated in cancer cells. These agents being more specific to cancer cells were expected to be less toxic than cytotoxic agents. Targeted agents have provided clinical benefit in many GI cancer types...

Characteristics of novel human membrane androgen receptor (mAR), ZIP9 (SLC39A9), were investigated in ZIP9-transfected PC-3 cells (PC3-ZIP9). Ligand blot analysis showed plasma membrane [(3)H]-T binding corresponds to the position of ZIP9 on Western blots which suggests ZIP9 can bind [(3)H]-T alone, without a protein partner. Progesterone antagonized testosterone actions, blocking increases in zinc, Erk phosphorylation and apoptosis, further evidence that ZIP9 is specifically activated by androgens. Pre-treatment with GTPγS and pertussis toxin decreased plasma membrane [(3)H]-T binding and blocked testosterone-induced increases in Erk phosphorylation and intracellular zinc, indicating ZIP9 is coupled to an inhibitory G protein (Gi) that mediates both MAP kinase and zinc signaling...

Mammalian thioredoxin reductase (TrxR) plays a vital role in restoring cellular redox balance disrupted by reactive oxygen species (ROS) generation and oxidative damage. Here, we evaluated whether auranofin, a selective inhibitor of TrxR, could serve as a potential anti-cancer agent through its selective targeting of TrxR activity in Hep3B hepatocellular carcinoma cells. Auranofin treatment reduced the TrxR activity of these cells and induced apoptosis, which were accompanied by up-regulation of death receptors (DRs) and activation of caspases, as well as promotion of proteolytic degradation of poly(ADP-ribose)-polymerase...

OBJECTIVE: Postoperative patients with gastrointestinal (GI) cancer have multiple adaptation tasks and care needs to improve their quality of life (QOL). Whether their supportive care needs differ according to their physical and psychosocial conditions is unclear. This study investigated patients' (1) physical and psychosocial conditions (QOL, fatigue, anxiety, cognitive plight, and resilience) and (2) responses to an informational booklet describing cancer patients' problems and adaptation tasks, and examined the association between the two factors...

The artificial nanostructures such as nanoparticles and natural nanostructures such as secreted nano-sized extracellular vesicles known as exosomes are promising tools for the realization of personalized medicine. Radionanomedicine is a recently coined term for the simultaneous application of either radiation technology or nuclear medicine with nanomedicine. In addition, radioexosomics is our suggested term for the study of exosomes functions, cytotoxicity, cancerogenicity, and biodistribution using radiation technology and nuclear medicine tracing technology...

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...

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 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...

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...

BACKGROUND: We aimed to clarify the long-term outcomes of patients with T1 colorectal carcinoma (CRC) after endoscopic resection (ER) and surgical resection. METHODS: We examined T1 CRC patients treated during 1992-2008 and who had ≥5 years of follow-up. Patients who did not meet the curative criteria after ER according to the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines were defined as "non-endoscopically curable" and classified into three groups: ER alone (Group A: 121 patients), additional surgery after ER (Group B: 238 patients), and surgical resection alone (Group C: 342 patients)...

A new series of 2,5 and 1,5-regioisomers of the tetrazolyl group viz., 3-[(5-benzyl/benzylthio-2H-tetrazol-2-yl) methyl]-2-chloro-6-substituted quinoline 6h-q and 3-[(5-benzyl/benzylthio-1H-tetrazol-1-yl) methyl]-2-chloro-6-substituted quinolines 7h-q were synthesized. Docking studies of all these compounds with DNA as target using PDB: 1AU5 and 453D revealed that the compounds 6h and 6i act as covalent cross linker on the DNA helix of the former and intercalate the latter both with higher C score values. Another set of docking studies in the active pocket of dihydrofolate reductase and N-myristoyl transferase as targets to assess antifungal activity revealed that compounds 6k, 6l, 6p and 7q (with bromo and fluro substituents) showcases different binding modes and hydrogen bonding...

Mohamad El-Zaatari, John Y Kao
The host immune response to gastrointestinal (GI) infections, hypersensitivity reactions, or GI cancers comprises numerous pathways that elicit responses on different host cells. Some of these include (1) the stimulation of mast cells via their IgE receptor, (2) the production of antibodies leading to antibody-mediated cytotoxic T/natural killer cell killing, (3) the activation of the complement pathway, and (4) the activation of the adaptive immune response via antigen-presenting cell, T cell, and B cell interactions...
