AB - Oxidative stress has long been known as a pathogenic factor of ulcerative colitis
(UC) and colitis-associated colorectal cancer (CAC), but the effects of secondary
carbonyl lesions receive less emphasis. In inflammatory conditions, reactive
oxygen species (ROS), such as superoxide anion free radical (O2 (-)), hydrogen
peroxide (H2O2), and hydroxyl radical (HO()), are produced at high levels and
accumulated to cause oxidative stress (OS). In oxidative status, accumulated ROS
can cause protein dysfunction and DNA damage, leading to gene mutations and cell
death. Accumulated ROS could also act as chemical messengers to activate
signaling pathways, such as NF-kappaB and p38 MAPK, to affect cell proliferation,
differentiation, and apoptosis. More importantly, electrophilic carbonyl
compounds produced by lipid peroxidation may function as secondary pathogenic
factors, causing further protein and membrane lesions. This may in turn
exaggerate oxidative stress, forming a vicious cycle. Electrophilic carbonyls
could also cause DNA mutations and breaks, driving malignant progression of UC.
The secondary lesions caused by carbonyl compounds may be exceptionally important
in the case of host carbonyl defensive system deficit, such as aldo-keto
可必特
reductase 1B10 deficiency. This review article updates the current understanding
of oxidative stress and carbonyl lesions in the development and progression of UC
and CAC.

updated experimental and clinical evidence.

AB - Inflammatory bowel disease (IBD) comprises primarily the chronic relapsing
inflammatory disorders, Crohn's disease and ulcerative colitis, with the former
affecting any part of the gastrointestinal tract and the latter mainly afflicting
the colon. The precise etiology of IBD remains unclear, and it is thought that
interactions among various factors, including genetic factors, the host immune徐粲然
system and environmental factors, cause disruption of intestinal homeostasis,
leading to dysregulated inflammatory responses of the gut. As inflammation is
intimately related to formation of reactive intermediates, including reactive
oxygen and nitrogen species (ROS/RNS), oxidative stress has been proposed as a
mechanism underlying the pathophysiology of IBD. This review is intended to
summarize succinctly recent new experimental and clinical evidence supporting
oxidative stress as a pathophysiological component of IBD and point to the
potential of using antioxidant compounds as promising therapeutic modalities of
human IBD. The sources of ROS/RNS and the redox signaling mechanism underlying
oxidative stress and inflammation in IBD are discussed to provide insight into
the molecular basis of oxidative stress as a pathophysiological factor in IBD.

challenges and opportunities.

AB - Oxygen free radicals in excessively high amounts are all very reactive chemically
and can impose a detrimental influence on living organisms by provoking
"oxidative stress" that can damage major cellular constituents. The latter
includes the cell membrane, cytoplasmic proteins, and nuclear DNA. Conversely,
nitric oxide (NO), superoxide anion, and related reactive oxygen species (ROS)
when present in low amounts play an important role as regulatory mediators in
signaling processes, through which, paradoxically, many ROS-mediated responses
can protect the cells against oxidative stress by induction of "redox
homeostasis." Therefore, diseases associated with free radical overproduction are
provoked by "blazed ROS productions" far beyond the host's capacity to quench.
Free radicals have been implicated in the pathogenesis of diverse
gastrointestinal (GI) diseases including gastroesophageal reflux disease (GERD),
gastritis, enteritis, colitis and associated cancers as well as pancreatitis and
liver cirrhosis. This article provides an overview of the role of oxidative
stress in inflammation-based GI tract diseases, including reflux esophagitis,
Helicobacter pylori-associated gastritis, non-steroidal anti-inflammatory
军事卫星drug-induced enteritis, ulcerative colitis, and associated colorectal cancer. The
challenging issue that ROS can contribute to diverse gastrointestinal
dysfunction, or manifest dual roles in cancer promotion or cancer suppression
will also be discussed for the opportunity to enhance understanding of
inflammation-based GI diseases.
