Abstract
In this work the relationship between Schistosoma mansoni (Sm) and the induction and progression of colorectal cancer (CRC) is examined. Various clinical studies reviewed here yield inconsistent results, with some reporting no association between Sm infection and CRC and others suggesting a probable to strong association. Here we propose a number of plausible mechanisms whereby Sm infection might contribute to CRC induction and/or progression. These factors are (1) chronic inflammation, (2) exposure to parasite linked antigens and genotoxic products, especially soluble egg antigens (SEAs) and (3) alteration of the intestinal microbiota. These factors probably predispose humans towards CRC and can help in CRC progression however only widespread epidemiological, clinical and pathological studies can firmly establish their role or a complete lack of it.
期刊介绍:
The journal provides a medium for rapid publication of investigations of the molecular biology and biochemistry of parasitic protozoa and helminths and their interactions with both the definitive and intermediate host. The main subject areas covered are:
• the structure, biosynthesis, degradation, properties and function of DNA, RNA, proteins, lipids, carbohydrates and small molecular-weight substances
• intermediary metabolism and bioenergetics
• drug target characterization and the mode of action of antiparasitic drugs
• molecular and biochemical aspects of membrane structure and function
• host-parasite relationships that focus on the parasite, particularly as related to specific parasite molecules.
• analysis of genes and genome structure, function and expression
• analysis of variation in parasite populations relevant to genetic exchange, pathogenesis, drug and vaccine target characterization, and drug resistance.
• parasite protein trafficking, organelle biogenesis, and cellular structure especially with reference to the roles of specific molecules
• parasite programmed cell death, development, and cell division at the molecular level.
