Insights

Damage-associated molecular pattern molecules (DAMPs) are released from stressed cells and activate innate immunity, promoting cancer growth and chemoresistance. Targeting DAMPs offers a promising avenue for novel melanoma treatments.

Area of Science:

  • Immunology
  • Oncology
  • Molecular Biology

Background:

  • Damage-associated molecular pattern molecules (DAMPs) are endogenous danger signals released from stressed or damaged cells.
  • These molecules activate innate immune responses, contributing to inflammation even without infection.
  • DAMPs play a significant role in the tumor microenvironment, influencing cancer progression.

Purpose of the Study:

  • To elucidate the role of DAMPs in melanoma pathogenesis.
  • To explore the potential of DAMPs as therapeutic targets for melanoma and chemoresistance.

Main Methods:

  • Analysis of DAMPs and DAMP receptors in melanoma models.
  • Investigation of DAMPs' effects on inflammation, angiogenesis, autophagy, and apoptosis in cancer.

Main Results:

  • DAMPs were found to be key players in melanoma development.
  • DAMPs facilitate cancer growth by regulating tumor microenvironment inflammation, promoting angiogenesis, and mediating autophagy while evading apoptosis.
  • DAMPs contribute to chemoresistance in melanoma.

Conclusions:

  • DAMPs are critical mediators in melanoma pathogenesis and chemoresistance.
  • Targeting DAMPs and their receptors presents a promising strategy for developing novel melanoma therapies.

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...

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...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

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...
