Insights

Epithelial-mesenchymal transition (EMT) drives cancer drug resistance by altering cell properties, similar to cancer stem cells. Targeting EMT offers a new strategy to overcome treatment resistance in cancer.

Area of Science:

  • Oncology
  • Cell Biology

Background:

  • Epithelial-mesenchymal transition (EMT) is implicated in cancer progression and drug resistance.
  • The precise role of EMT in metastasis is debated, but its contribution to drug resistance is increasingly evident.
  • EMT shares characteristics with cancer stem cells (CSCs), including enhanced drug efflux and apoptosis resistance.

Purpose of the Study:

  • To elucidate the mechanisms by which EMT contributes to cancer drug resistance.
  • To review recent advancements in understanding EMT-associated drug resistance.

Main Methods:

  • This is a review article, synthesizing existing research.
  • Literature search on EMT, cancer progression, metastasis, drug resistance, and cancer stem cells.

Main Results:

  • EMT confers drug resistance through various signaling pathways.
  • EMT-induced cells exhibit CSC-like properties, such as increased drug efflux and anti-apoptotic effects.
  • Targeting EMT presents a potential therapeutic strategy against drug-resistant cancers.

Conclusions:

  • EMT plays a significant role in cancer drug resistance.
  • Understanding EMT mechanisms is crucial for developing novel cancer therapies.
  • Targeting EMT pathways may overcome resistance and improve patient outcomes.

Metastasis

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

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...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

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...
