In this article we review the role of vascular endothelial growth factor (VEGF) in colon cancer growth and the underlying mechanisms. Angiogenesis, the growth of new capillary blood vessels in the body, is critical for tissue injury healing and cancer growth. In 1971, Judah Folkman proposed the concept that tumor growth beyond 2 mm is critically dependent on angiogenesis. Tumors including colon cancers release angiogenic gr Read More

Glucocorticoids may have dual action on the gastric mucosa: gastroprotective and ulcerogenic. In this article, we review the data which suggested that an initial action of endogenous glucocorticoids, including stress-produced ones as well as exogenous glucocorticoids is gastroprotective and consider possible mechanisms of the conversion of physiological gastroprotective action of glucocorticoid hormones to their pathologica Read More

The intestinal inflammation caused by intestinal ischemia reperfusion during acute pancreatitis (AP) often leads to multiple organ dysfunction and aggravation of acute pancreatitis. This review concerns up-date progress of the pathophysiology and molecular mechanism of the excessive production of gut-derived cytokines. The regulation effects of immuno-neuro-endocrine network for pancreatic necrosis are the basis fo Read More

Inflammatory bowel disease (IBD) is a chronic and relapsing inflammatory condition of the gastrointestinal tract. The two main forms of IBD are Crohn's disease and ulcerative colitis. According to the recent concept the disease is caused by a combination of factors, including genetics, immune dysregulation, barrier dysfunction and the change in microbial flora. Environmental factors, such as changes in diet, antibiotic u Read More

Ulcerative colitis (UC) and Crohn’s disease (CD) constitute the two major groups of idiopathic disorders in inflammatory bowel disease (IBD). Environmental factors, genetic factors and immune responses have been considered as the major etiology of IBD. Despite the diversified pathogenesis of the disease, no guaranteed curative therapeutic regimen has been developed so far. This review summarizes the knowl Read More

In addition to eradication of Helicobacter pylori, chemotherapy with anticancer agents, and radiation therapy, the treatment with molecular target drugs including rituximab, a CD20 antagonist, is one of the promising new regimens. The mucosa-associated lymphoid tissue (MALT) lymphoma is histologically characterized by rich distribution of the microvascular network consisting of the immature capillaries, lymphatics and venu Read More

The pancreas and salivary glands have similar anatomical structures and physiological functions producing bicarbonate-rich fluid containing digestive enzymes and other components to be delivered into the gut. Despite these similarities, the two organs are also different in numerous respects, especially regarding the inflammatory diseases affecting them. This article will summarize the pathophysiology and current an Read More

This review focuses on the described effects of BPC 157 on blood vessels after different types of damage, and elucidate by investigating different aspects of vascular response to injury (endothelium damage, clotting, thrombosis, vasoconstriction, vasodilatation, vasculoneogenesis and edema formation) especially in connection to the healing processes. In this respect, BPC 157 was concluded to be the most potent angiomodula Read More

We reviewed stable gastric pentadecapeptide BPC 157-NO-system-relation, its close participation in Moncada's (maintained vascular integrity, platelets control) homeostatic healing response of NO-system to injury. Namely, BPC 157’s particular healing effect also affects all events after vascular integrity loss (dependent on circumstances, it reduces either thrombosis (abdominal aorta anastomosis) or bleeding/thrombocy Read More

Skin and gut represent physical and immunological barriers between internal and external environment. Some affections involving the intestine, such as celiac disease, are reported to be associated with several different cutaneous diseases, like dermatitis herpetiforme or psoriasis. This could be better explained if gut and skin are taken as complex structures that share physio-pathological and immunological aspects. As a proo Read More

We set up two models of gastric bleeding in rats using low-dose aspirin (ASA) and the antiplatelet drug clopidogrel, a P2Y12 receptor antagonist, and examined the effect of antiulcer drugs on gastric bleeding and ulcerogenic responses under such conditions. Under urethane anesthesia, two catheters were inserted into the rat stomach, one from the esophagus and another through the pylorus via an incision in the duodenum. Read More

A growing body of experimental and clinical evidence supports the hypothesis that the intestinal microbiota markedly influences function and the structure of the mucosal lining. Intestinal microbiota can potentially cause damage to the mucosa either directly by releasing toxins or indirectly by causing a detrimental immune response. Probiotic bacteria have been defined as live microorganisms, which when consumed in adequa Read More

Aims: The aims of this study were to determine a mechanism and general timeline for statin related anti-inflammatory activity. Methods: Healthy male subjects received rosuvastatin (20 mg daily) for 3 weeks. Blood samples before and after treatment were collected for clinical laboratories and research procedures. Toll-like receptor-4 (tlr-4) expression on blood monocytes was measured using flow cytometry before and afte Read More

Background and Aims: Polyphenolic acetates (PAs) have antioxidant/ pro-oxidant properties and can also acetylate proteins (enzymes) by a novel acetoxy drug: calreticulin transacetylase acetylation system. While PAs have been investigated as pharmacological agents for the treatment of various diseases, their potential as anti-cancer agents or their efficacy as an adjuvant in anti-cancer therapeutics remains to be explore Read More
