Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.9K
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...

Targeted Cancer Therapies

7.0K
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

51.3K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

2.6K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Drug Classes and Categories01:25

Drug Classes and Categories

3.1K
Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...

Summary

Cancer drugs can be optimized by viewing them as classifiers that discriminate between cancer and healthy cells using molecular markers. This framework helps design more accurate cancer drugs and drug combinations.

Area of Science:

  • Biomedical Sciences
  • Computational Biology
  • Pharmacology

Background:

  • Cancer and healthy cells exhibit distinct molecular profiles, influencing drug responses.
  • Cellular heterogeneity complicates selective cancer drug action.
  • Current cancer drugs aim for selective toxicity but face challenges due to cell variance.

Purpose of the Study:

  • To develop a classification framework for ideal cancer drugs based on molecular discrimination.
  • To explore the use of measurable cell markers for distinguishing cancer from healthy cells.
  • To optimize drug action for improved cancer treatment selectivity.

Main Methods:

  • Formalized a classification framework for cancer drugs.
  • Evaluated molecular markers for single-cell discrimination between cancer and healthy cells.
  • Assessed the predictive power of gene expression on drug efficacy.
  • Formulated a framework for optimal drug and drug cocktail design.

Main Results:

  • A small set of genes effectively discriminates between individual cancer and healthy cells.
  • Gene expression profiles statistically predict the efficacy of certain cancer drugs.
  • Identified existing cancer drugs as suboptimal classifiers based on gene expression.
  • Developed a framework for designing optimal drugs and predicting synergistic drug cocktails.

Conclusions:

  • Conceptualizing cancer drugs as classifiers in molecular marker space offers a novel design paradigm.
  • This approach promises to enhance the accuracy of cancer drug and drug cocktail development.
  • Measurable molecular markers are key to achieving selective cancer cell targeting.
