Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.7K
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 Therapies

9.9K
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...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

5.9K
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...

Nature and Nurture01:10

Nature and Nurture

22.2K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Protein Networks02:26

Protein Networks

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Cell Potential and Free Energy02:58

Cell Potential and Free Energy

46.3K
Thermodynamics of a Redox Reaction
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...

Area of Science:

  • Oncology
  • Pharmacology
  • Bioinformatics

Background:

  • Research shows synergy between natural products and anti-neoplastic drugs in cancer treatment.
  • The biological mechanisms underlying this synergy remain largely unknown.

Purpose of the Study:

  • To investigate the targetable biological space of natural products in cancer.
  • To provide a rational basis for developing novel combination therapies for cancer.

Main Methods:

  • Utilized public domain compound-target information to assess natural product targets.
  • Analyzed pathways from the Reactome database and cancer driver genes.
  • Compared natural product targets with FDA-approved cancer drugs using the Cancer Targetome resource.
  • Evaluated target interactions at a binding affinity threshold of < 100nM.

Main Results:

  • Natural products increased pathway coverage by 61% (725 pathways) compared to existing cancer drugs.
  • Natural products expanded coverage of both pathways and specific targets within those pathways.
  • Identified 24 cancer driver-enriched pathways with natural product interactions but no drug interactions at < 100nM.
  • Natural products exhibit distinct and overlapping target groupings with cancer drugs, suggesting complementary potential.

Conclusions:

  • Natural products target a broad range of biological pathways relevant to cancer.
  • Natural products interact with critical cancer driver genes, offering therapeutic potential.
  • This study establishes a foundation for novel cancer treatments combining natural products and conventional drugs.
