Insights

Damage-associated molecular patterns (DAMPs) signal cell death and inflammation. Emerging research shows DAMPs can both promote and fight cancer, influencing tumor growth and anti-cancer therapies.

Area of Science:

  • Immunology
  • Oncology
  • Cell Biology

Background:

  • Damage-associated molecular patterns (DAMPs) are released during cell death and stress, initiating sterile inflammation.
  • DAMPs are increasingly implicated in cancer development and the body's response to anti-cancer treatments.

Purpose of the Study:

  • To review the role of DAMPs and their receptors in cancer.
  • To discuss evidence for DAMPs acting as both tumor promoters and anti-tumor effectors.
  • To highlight unresolved questions regarding DAMPs in the tumor microenvironment.

Main Methods:

  • Literature review of existing research on DAMPs in cancer.
  • Analysis of studies investigating DAMPs' impact on tumor cell death and inflammation.
  • Examination of evidence for DAMPs' dual role in tumor progression and immune response.

Main Results:

  • DAMPs can trigger immunogenic cell death, alerting the immune system to tumor cells.
  • Conversely, DAMPs can fuel chronic inflammation, potentially promoting tumor growth and progression.
  • The precise mechanisms and contexts for DAMPs' pro- or anti-tumor effects are complex and require further investigation.

Conclusions:

  • DAMPs represent a critical link between cell death, inflammation, and cancer.
  • Understanding DAMPs' multifaceted roles is essential for developing novel cancer therapies.
  • Further research is needed on DAMP release from non-tumor cells and the existence of tumor-specific DAMPs.

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

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

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,...
