Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.4K
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...

Cancer Prevention

6.0K
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.
Some...

Combination Therapies and Personalized Medicine

4.8K
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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

4.6K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Cancer Therapies

7.5K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Area of Science:

  • Nutritional Science
  • Pharmacology
  • Oncology

Background:

  • Polyphenols (PFs) possess antioxidant, anti-inflammatory, and anticancer properties found in fruits and vegetables.
  • Poor bioavailability, stemming from low solubility and rapid metabolism, limits the therapeutic efficacy of PFs.
  • Current research explores novel delivery systems to overcome these limitations and enhance PF effectiveness.

Purpose of the Study:

  • To review factors influencing polyphenol bioavailability.
  • To analyze in vivo and clinical evidence of PFs' anticancer effects and mechanisms.
  • To explore strategies for enhancing polyphenol delivery and efficacy in cancer therapy.

Main Methods:

  • Literature review of studies on polyphenol bioavailability and anticancer effects.
  • Analysis of in vivo data from animal models and human clinical trials.
  • Evaluation of various delivery systems and strategies to improve polyphenol stability and absorption.

Main Results:

  • Bioavailability challenges significantly hinder polyphenol translation to clinical cancer treatment.
  • Delivery systems like nanoparticles and hydrogels show potential for protecting PFs and improving targeted delivery.
  • Clinical trials and animal studies provide evidence for polyphenol modulation of cancer pathways, though results vary.

Conclusions:

  • Enhanced delivery systems are crucial for realizing the full anticancer potential of polyphenols.
  • Future research should focus on optimizing delivery, combining PFs with conventional therapies, and exploring epigenetic and microenvironment interactions.
  • Polyphenols represent a promising complementary approach for cancer therapy, with personalized medicine and structural modifications offering future advancements.
