Insights

Dysfunctional Wnt, Hedgehog, and Notch pathways drive cancer stem cells (CSCs). Targeting these pathways offers a promising strategy to eliminate CSCs and improve cancer treatment outcomes.

Area of Science:

  • Oncology
  • Developmental Biology
  • Molecular Biology

Background:

  • Wnt, Hedgehog, and Notch pathways are crucial for embryonic development and tissue homeostasis.
  • Aberrant signaling in these pathways is linked to various cancers.
  • These pathways play a key role in the biology of cancer stem cells (CSCs).

Purpose of the Study:

  • To review the roles of Wnt, Hedgehog, and Notch pathways in cancer stem cell stemness and function.
  • To summarize therapeutic strategies targeting these pathways for cancer treatment.

Main Methods:

  • Literature review of studies on Wnt, Hedgehog, and Notch pathways in cancer stem cells.
  • Analysis of therapeutic interventions targeting these signaling pathways.

Main Results:

  • The Wnt, Hedgehog, and Notch pathways are essential for CSC self-renewal, proliferation, and survival.
  • Dysregulation of these pathways contributes to tumor initiation, growth, and metastasis.
  • Targeting these pathways has shown potential in eradicating CSCs in preclinical and clinical studies.

Conclusions:

  • Wnt, Hedgehog, and Notch pathways are critical regulators of CSCs.
  • Therapeutic targeting of these pathways represents a promising approach to overcome cancer recurrence and improve patient outcomes.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

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...
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 specific...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
