Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

5.8K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Cancer Stem Cells and Tumor Maintenance

4.9K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.3K
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...

Metastasis02:30

Metastasis

5.6K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.6K
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...

Summary
This summary is machine-generated.

Drug resistance in cancer is a major hurdle. The tumor microenvironment (TME) drives tumor heterogeneity and the evolution of drug-resistant tumor-persistent cells (TPCs) through metabolic and epigenetic changes.

Area of Science:

  • Oncology
  • Cancer Biology
  • Tumor Microenvironment Research

Background:

  • Anticancer therapy resistance remains a critical challenge in cancer treatment.
  • The tumor microenvironment (TME) significantly influences the development of drug resistance.
  • Tumor heterogeneity (TH) and epigenetic adaptations are key factors in resistance acquisition.

Purpose of the Study:

  • To explore the link between TME metabolic pressures, epigenetics, and tumor-persistent cell (TPC) evolution.
  • To understand how TPCs gain resistance advantages through phenotypic and metabolic plasticity.
  • To identify novel therapeutic targets for overcoming drug resistance by exploiting TPC vulnerabilities.

Main Methods:

  • Analysis of tumor microenvironment components.
  • Investigation of epigenetic modifications in tumor cells.
  • Characterization of tumor-persistent cell (TPC) plasticity and metabolism.
  • Correlation of metabolic pressures with TPC evolution and drug resistance.

Main Results:

  • The TME fosters tumor heterogeneity and the emergence of drug-resistant clones.
  • Metabolic pressures within the TME promote epigenetic adaptations in tumor cells.
  • Tumor-persistent cells (TPCs) exhibit significant phenotypic and metabolic plasticity, conferring chemo- and radio-resistance.

Conclusions:

  • Understanding the interplay between TME metabolism, epigenetics, and TPC evolution is crucial.
  • Targeting TPC vulnerabilities presents a promising strategy to overcome anticancer therapy resistance.
  • Novel therapeutic approaches can be developed by focusing on the metabolic and epigenetic plasticity of TPCs.
