Abstract

Insights

Selective COX-2 inhibitors (coxibs) show promise for colorectal cancer (CRC) chemoprevention by targeting inflammation pathways. However, cardiovascular risks limit their use, necessitating further research into safer alternatives.

Area of Science:

  • Oncology
  • Pharmacology

Background:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs) demonstrated efficacy in colorectal cancer (CRC) chemoprevention.
  • NSAIDs' side effects prompted research into safer alternatives like selective COX-2 inhibitors (coxibs).

Purpose of the Study:

  • To review the role of coxibs in the chemoprevention of colorectal cancer (CRC).

Main Methods:

  • Review of in-vitro and in-vivo experimental data on coxibs for CRC chemoprevention.
  • Analysis of clinical trial data regarding coxib efficacy and safety.

Main Results:

  • Coxibs demonstrated effectiveness in preclinical CRC chemoprevention models.
  • Celecoxib received FDA approval for familial adenomatous polyposis treatment.
  • Studies revealed an increased risk of cardiovascular events associated with coxib use compared to placebo.

Conclusions:

  • The anti-cancer activity of coxibs may stem from their multi-directional effects, including NF-kappaB inhibition.
  • NF-kappaB modulation presents a potential future target for effective CRC chemoprevention strategies.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
Cancer Prevention02:59

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.

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
