Formation of the Platelet Plug01:22

Formation of the Platelet Plug

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Structure and Function of Platelets01:18

Structure and Function of Platelets

The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
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...
Tumor Progression02:07

Tumor Progression

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...
Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...
Cancer-Critical Genes I: Proto-oncogenes01:33

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Summary

Platelets play a key role in cancer progression and metastasis by interacting with tumors. Anti-platelet agents may disrupt this deadly loop, potentially reducing cancer risk and mortality.

Area of Science:

  • Oncology
  • Hematology
  • Cancer Biology

Background:

  • The link between cancer and thrombosis, known since 1865, involves platelets.
  • Platelets are crucial in hemostasis and play a significant role in cancer-induced thrombosis.
  • Tumor cells induce platelet abnormalities, affecting coagulation and promoting metastasis.

Purpose of the Study:

  • To review the reciprocal interactions between platelets and cancer.
  • To explore the potential of anti-platelet agents in managing cancer progression and thrombosis.

Main Methods:

  • Literature review of studies on platelet-cancer interactions.
  • Analysis of research on anti-platelet agents in cancer contexts.

Main Results:

  • Platelets contribute to tumor growth, angiogenesis, and metastasis by releasing growth factors.
  • A feedback loop exists where tumor-induced platelet activation promotes tumor spread, and platelets amplify tumor growth.
  • Emerging evidence suggests anti-platelet agents may reduce cancer incidence, mortality, and metastasis risk.

Conclusions:

  • Platelets and cancer engage in a complex, reciprocal relationship that promotes tumor progression.
  • Anti-platelet therapy shows promise in disrupting this cycle, potentially offering therapeutic benefits in cancer care.
  • Further research is needed to establish the efficacy of anti-platelet agents in reducing cancer-induced thrombosis.
