Oxaliplatin is a first-line chemotherapeutic agent used for the treatment of colorectal cancer. Its use is associated with severe gastrointestinal (GI) side-effects, associated with oxidative damage and neurotoxicity to the enteric neurons. Resveratrol is a potent anti-oxidant that has been shown to protect against oxidative damage and neurotoxicity in other neurons and could therefore prevent oxaliplatin-induced damage to enteric neurons. We determined whether co-administration of resveratrol with oxaliplatin alleviates enteric neuron toxicity and GI dysfunction in mice...

Immune checkpoint inhibitors represent revolutionary anti-cancer agents, being rapidly approved in different malignancies and settings. Gastrointestinal (GI) cancers represent a wide variety of tumors with specific characteristics and different responses to various therapeutic alternatives; while some are chemo-sensitive others are chemo-resistant and only respond to more aggressive cytotoxic regimens, targeted therapies or a combination of both. Preliminary results of immune checkpoint inhibitors in some GI cancers are promising, namely in hepatocellular carcinoma, anal cancers and microsatellite instability high colorectal cancers...

Glottal insufficiency (GI) is a cause of breathy voice that can profoundly affect quality of voice. Main causes are unilateral vocal fold paralysis or endoscopic cordectomy for the early treatment of laryngeal cancer of the glottis. The main strategy in surgical treatment is type I medialization thyroplasty according to Isshiki with the use of implants e.g. silastic, hydroxyapatite, titanium, Gore-Tex or Montgomery. Other procedures are arytenoid adduction, the injection laryngoplasty via thyrohyoid and cricothyroid approach and laryngeal reinnervation...

Recently, the interplay between autophagy and apoptosis has become an important factor in chemotherapy for cancer treatment. Inhibition of autophagy may be an effective strategy to improve the treatment of chemo-resistant cancer by consistent exposure to chemotherapeutic drugs. However, no reports have clearly elucidated the underlying mechanisms. Therefore, in this study, we assessed whether salinomycin, a promising anticancer drug, induces apoptosis and elucidated potential antitumor mechanisms in chemo-resistant prostate cancer cells...

Although radiotherapy is a highly effective treatment for abdominal or pelvic cancer patients, it can increase the incidence of severe gastrointestinal (GI) toxicity. As an intestinal growth factor, glucagon-like peptide 2 (GLP-2) has been shown to improve the preclinical models of both short bowel syndrome and inflammatory bowel disease by stimulating intestinal growth. Teduglutide ([Gly(2)]GLP-2), a recombinant human GLP-2 variant, has a prolonged half-life and stability as compared to the native GLP-2 peptide, but still requires daily application in the clinic...

We introduce a label-free biosensing cellulose strip sensor with surface-enhanced Raman spectroscopy (SERS)-encoded bimetallic core@shell nanoparticles. Bimetallic nanoparticles consisting of a synthesis of core Ag nanoparticles (AgNP) and a synthesis of shell gold nanoparticles (AuNPs) were fabricated on a cellulose substrate by two-stage successive ionic layer absorption and reaction (SILAR) techniques. The bimetallic nanoparticle-enhanced localized surface plasmon resonance (LSPR) effects were theoretically verified by computational calculations with finite element models of optimized bimetallic nanoparticles interacting with an incident laser source...

The proto-oncogene PTTG and its binding partner PBF have been widely studied in multiple cancer types, particularly thyroid and colorectal, but their combined role in tumourigenesis is uncharacterised. Here, we show for the first time that together PTTG and PBF significantly modulate DNA damage response (DDR) genes, including p53 target genes, required to maintain genomic integrity in thyroid cells. Critically, DDR genes were extensively repressed in primary thyrocytes from a bitransgenic murine model (Bi-Tg) of thyroid-specific PBF and PTTG overexpression...

Rapid, androgen actions initiated at the cell surface have been reported in a variety of vertebrate cells, including several macrophage and prostate cancer cell lines that lack the nuclear androgen receptor. However, until recently the identity of the novel membrane androgen receptor (mAR) mediating these nonclassical androgen actions remained unknown. In 2014, a novel mAR unrelated to nuclear androgen receptors was identified in Atlantic croaker ovaries as the zinc transporter protein, ZIP9. ZIP9 is one of the 14 members of the ZIP (ZRT-and Irt-like Protein, SLC39A) family that regulates zinc homeostasis by transporting zinc across cell and organelle membranes into the cytoplasm...

BACKGROUND/AIMS: The use of antiangiogenic agents (AAs) in cancer treatment has increased because they offer survival benefit in combination with cytotoxic chemotherapy. Given their potential to cause gastrointestinal (GI) perforation and bleeding, it is currently recommended that AAs be held for 28 days before and after surgery. However, there are no specific guidelines which address their use around endoscopic procedures because data regarding the safety of endoscopy in cancer patients while on AAs is scarce despite the fact that these patients often require endoscopy...
