Insights

Cancer stem cells resist therapy via epithelial-mesenchymal transition. A metabolic switch to glucose metabolism in basal-like breast cancer reduces reactive oxygen species, promoting this phenotype.

Area of Science:

  • Oncology
  • Cancer Biology
  • Metabolic Pathways

Background:

  • Cancer stem cells (CSCs) exhibit epithelial-mesenchymal transition (EMT), conferring therapeutic resistance.
  • Basal-like breast cancer is a subtype characterized by aggressive behavior and poor prognosis.

Discussion:

  • The study investigates the metabolic underpinnings of EMT in basal-like breast cancer.
  • It explores the link between glucose metabolism and reactive oxygen species (ROS) levels in CSCs.

Key Insights:

  • A metabolic switch to glucose metabolism promotes EMT phenotypes in basal-like breast cancer.
  • This metabolic shift leads to decreased reactive oxygen species levels, contributing to CSC survival and therapy resistance.

Outlook:

  • Targeting metabolic pathways could offer novel therapeutic strategies for basal-like breast cancer.
  • Further research into ROS regulation in CSCs may reveal new avenues for overcoming treatment resistance.

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.
The mTOR pathway or the...
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...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
Metastasis02:30

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...
Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

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,...
