Insights

Inhibiting 11beta-hydroxysteroid dehydrogenase type II (11betaHSD2) may offer a new colon cancer therapy. This approach reduces tumor growth and metastasis by targeting COX-2 signaling without the side effects of traditional NSAIDs.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Cyclooxygenase-2 (COX-2) is a key driver of colon cancer progression.
  • Current treatments like NSAIDs and selective COX-2 inhibitors have significant gastrointestinal and cardiovascular side effects.
  • The need for safer, effective colon cancer therapies is critical.

Discussion:

  • The study by Zhang et al. demonstrates that inhibiting 11beta-hydroxysteroid dehydrogenase type II (11betaHSD2) effectively reduces colon tumor COX-2 activity.
  • This inhibition leads to decreased tumor growth and metastasis.
  • The mechanism involves enhanced tonic glucocorticoid-mediated suppression of the COX-2 signaling pathway.

Key Insights:

  • Targeting 11betaHSD2 offers a novel therapeutic strategy for colon cancer.
  • This approach bypasses the adverse effects associated with NSAIDs and selective COX-2 inhibitors.
  • Gene silencing and licorice root derivatives were employed to achieve 11betaHSD2 inhibition.

Outlook:

  • 11betaHSD2 inhibition presents a promising avenue for colon cancer treatment.
  • Further research is warranted to explore the clinical potential of this therapeutic strategy.
  • This approach could lead to improved patient outcomes in colon cancer management.

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Drugs Affecting GI Tract Motility: Bulk-Forming and Stimulant Laxatives

Laxatives enhance bowel movements and alleviate constipation. They augment the stool's bulk, stimulate intestinal muscle contractions, draw water into the intestines, or soften the stool. There are five key types of laxatives: bulk laxatives, stimulant laxatives, osmotic laxatives, stool softeners, and lubricant laxatives.
Bulk-forming laxatives, such as psyllium, methylcellulose, and polycarbophil, absorb water in the intestine, increasing stool bulk and promoting bowel movement. This...

Drugs Affecting GI Tract Motility: Other Laxatives

Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
Osmotic or saline laxatives, like magnesium hydroxide or milk of...

Drugs for Treatment of Constipation-Predominant IBS

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
