Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

5.9K
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,...

The Tumor Microenvironment02:17

The Tumor Microenvironment

6.7K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

2.7K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Metastasis02:30

Metastasis

5.7K
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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.9K
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...

Area of Science:

  • Oncology
  • Cancer Biology
  • Tumor Microenvironment

Background:

  • The tumor microenvironment (TME) is a complex ecosystem where cellular interactions dictate cancer progression, metastasis, immunity, and treatment outcomes.
  • Angiogenesis, the formation of new blood vessels, is essential for tumor growth but leads to a hypoxic and acidic TME.
  • Cancer and stromal cells adapt their metabolism to meet high energy demands for rapid proliferation within this hostile environment.

Purpose of the Study:

  • To investigate the metabolic reprogramming of tumor endothelial cells.
  • To explore the impact of targeting endothelial metabolic pathways on vessel sprouting.
  • To evaluate the potential of metabolic antiangiogenic therapies combined with immunotherapies for cancer treatment.

Main Methods:

  • Analysis of metabolic pathways in tumor endothelial cells.
  • Investigating the effects of targeting endothelial metabolism on angiogenesis.
  • Evaluating combination therapy strategies.

Main Results:

  • Tumor endothelial cell metabolism is reprogrammed within the TME.
  • Targeting endothelial metabolic pathways influences pathological and developmental vessel sprouting.
  • Metabolic antiangiogenic therapies show potential for vascular normalization.

Conclusions:

  • The dynamic interplay within the TME is crucial for cancer development and treatment response.
  • Targeting endothelial cell metabolism offers a novel strategy to normalize tumor vasculature.
  • Combining metabolic antiangiogenic therapies with immunotherapies presents a promising clinical approach for cancer treatment.
