The Tumor Microenvironment02:17

The Tumor Microenvironment

7.3K
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...

Adaptive Mechanisms in Cancer Cells

6.2K
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,...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.1K
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...

Metastasis02:30

Metastasis

6.1K
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...

Cancer02:18

Cancer

52.1K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Tumor Progression02:07

Tumor Progression

6.9K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Summary

Cancer cells reprogram metabolism for growth using internal genetic changes and external tumor microenvironment signals. Targeting these metabolic pathways requires a personalized approach considering cancer type and location.

Area of Science:

  • Oncology
  • Cancer Metabolism
  • Molecular Biology

Background:

  • Cancer cells exhibit metabolic reprogramming crucial for growth, proliferation, and survival.
  • This reprogramming is influenced by oncogenic alterations and the tumor microenvironment.
  • Both intrinsic and extrinsic factors contribute to cancer cell metabolism.

Purpose of the Study:

  • To review the intrinsic and extrinsic mechanisms driving cancer metabolism.
  • To explore therapeutic targeting strategies for cancer metabolic reprogramming.

Main Methods:

  • Literature review of intrinsic and extrinsic mechanisms in cancer metabolism.
  • Analysis of signaling pathways and transcription factors involved.
  • Discussion of therapeutic implications.

Main Results:

  • Intrinsic mechanisms involve signal transduction and transcription factors enhancing metabolic enzyme activity.
  • Extrinsic mechanisms involve host-derived factors amplifying metabolic reprogramming.
  • Cancer metabolism is a result of converging intrinsic and extrinsic signals.

Conclusions:

  • Metabolic reprogramming is a hallmark of cancer, driven by both cancer-intrinsic and extrinsic factors.
  • Intrinsic signals establish baseline metabolism, while extrinsic signals fine-tune it.
  • Effective therapeutic targeting requires a nuanced approach considering cancer genotype, tumor microenvironment, and tissue location.
