Summary
Oxidative stress, an imbalance in reactive oxygen species (ROS), drives inflammation and cancer. This review details ROS
Area of Science:
- Biomedical Science
- Oncology
- Gastroenterology
Background:
- Oxidative stress results from an imbalance between reactive oxygen species (ROS) production and antioxidant defenses.
- Inflammatory cells like neutrophils and macrophages generate substantial ROS, exacerbating oxidative stress in inflamed tissues.
- A long-standing link exists between oxidative stress in inflammation and cancer development, particularly in chronic inflammatory bowel disease (IBD).
Purpose of the Study:
- To provide an overview of reactive oxygen species (ROS) pathology.
- To present recent findings on the role of ROS in colorectal carcinogenesis associated with IBD.
Main Methods:
- Literature review and synthesis of existing research on ROS and IBD-related colorectal cancer.
- Analysis of the pathological mechanisms linking ROS to cancer development in the context of inflammation.
Main Results:
- Oxidative stress is a key pathogenetic factor in the established correlation between inflammatory diseases and cancer.
- ROS play a significant role in the development of colorectal cancer in patients with IBD.
Conclusions:
- Understanding ROS pathology is crucial for comprehending IBD-related colorectal carcinogenesis.
- Further research into ROS mechanisms may offer novel therapeutic targets for preventing or treating IBD-associated cancers.

01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
01:30Peptic Ulcer Disease I: Introduction
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

01:25Peptic Ulcer Disease I: Introduction
Peptic ulcer disease (PUD) involves breaks in the gastrointestinal tract's mucosal lining, primarily in the stomach and duodenum, with less frequent occurrences in the lower esophagus or near the pylorus.Ulcers can be acute or chronic. Acute ulcers are short-lived with minimal inflammation and heal quickly after the irritant is removed. Chronic ulcers persist, may recur, and often cause scarring due to ongoing tissue damage. Superficial erosions affect only the mucosal layer and are called...
01:29Drugs for Treatment of Ulcerative Colitis in IBD
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide generation.
