Targeted Cancer Therapies

8.6K
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...

Combination Therapies and Personalized Medicine

5.8K
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...

Area of Science:

  • Oncology
  • Molecular Biology
  • Medical Chemistry

Background:

  • The Wnt pathway is frequently dysregulated in human cancers, particularly colorectal cancer, with over 90% of cases showing pathway variations.
  • Sulindac, a known therapeutic agent, targets the Wnt/Dvl/β-catenin pathway and has demonstrated efficacy in reducing colorectal cancer incidence and mortality.
  • There is a need for innovative therapeutic and diagnostic tools for effective colon cancer management.

Purpose of the Study:

  • To report the development of a novel dual-functional compound (SLN) integrating Sulindac's therapeutic properties with a fluorophore for cancer cell visualization.
  • To evaluate SLN's capacity for both identifying Wnt pathway targets and inhibiting colon tumor growth.
  • To explore SLN as a potential reagent for chemotherapy and a fluorescent indicator in surgical tumor removal.

Main Methods:

  • Synthesis and characterization of the dual-functional compound SLN, linking Sulindac with a fluorophore.
  • In vitro and/or in vivo studies to assess SLN's ability to target Dvl protein within the Wnt pathway.
  • Evaluation of SLN's efficacy in inhibiting colon cancer cell proliferation and tumor growth.
  • Assessment of SLN's utility as a fluorescent marker for tumor visualization.

Main Results:

  • The successful synthesis of SLN, a compound with combined chemotherapeutic and fluorescent imaging capabilities.
  • SLN effectively marks Dvl protein, enabling layer-by-layer recognition of colon cancer cells.
  • SLN demonstrated significant inhibition of colon cancer growth, indicating therapeutic potential.

Conclusions:

  • The developed dual-functional compound SLN offers a promising strategy for simultaneous diagnosis and treatment of colon cancer.
  • SLN serves as both a therapeutic agent targeting the Wnt pathway and a fluorescent probe for tumor visualization.
  • SLN presents a valuable tool for enhancing chemotherapy efficacy and improving surgical precision in colon cancer removal.
