Summary

This summary is machine-generated.

Volatile organic compounds (VOCs) in exhaled breath may indicate how well cancer therapies work. Researchers found distinct VOC signatures linked to drug resistance in colorectal cancer cells, paving the way for new biomarkers.

Area Of Science

  • Metabolomics and Lipidomics
  • Cancer Biomarkers
  • Precision Medicine

Background

  • Variable patient responses to cancer therapeutics impede clinical advancement.
  • Clinically translatable biomarkers are crucial for precision medicine trials.
  • Volatile organic compounds (VOCs) show promise for non-invasive cancer detection.

Purpose Of The Study

  • To investigate lipidomic and volatilomic profiles in drug-resistant and -sensitive colorectal cancer cells.
  • To explore the potential of VOCs as biomarkers for monitoring response to metabolically active therapies, specifically mTOR catalytic inhibitors (mTORci).

Main Methods

  • Comparative analysis of lipidomic and volatilomic profiles in sensitive and resistant colorectal cancer cell lines.
  • Identification of specific VOC signatures associated with drug resistance.
  • Correlation of VOC profiles with lipid structure and metabolism.

Main Results

  • Distinct lipid-derived VOC signatures, including alkenes, aldehydes, and fatty acids, were identified in mTORci-resistant cells.
  • Enriched VOCs correlated with alterations in phospholipid structure and desaturation, suggesting dysregulated lipid metabolism.
  • A novel association between VOCs and drug response was established in vitro.

Conclusions

  • VOCs may serve as non-invasive surrogates for monitoring therapeutic response in cancer.
  • This study provides a foundation for developing VOC-based biomarkers for treatment monitoring in clinical settings.
  • Further clinical trials are needed to translate these in vitro findings into clinical practice.

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...

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...

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...

Treatment Resistant Cancers 02:56

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...
