Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

3.3K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Extrinsic and Intrinsic Pathways of Hemostasis

11.2K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.5K
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...

Venous Thrombosis I: Introduction

168
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Tumor Progression02:07

Tumor Progression

7.1K
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...

Area of Science:

  • Oncology
  • Immunology
  • Hematology

Background:

  • Cancer progression involves complex interactions between tumor cells and host factors.
  • Inflammatory and hemostatic systems are key host-derived factors influencing cancer.
  • Chronic inflammation is linked to major cancers like colon, pancreatic, prostate, and breast adenocarcinoma.

Purpose of the Study:

  • To review the crosstalk between inflammation and hemostasis in cancer.
  • To elucidate how these systems cooperatively promote malignancy.
  • To identify novel therapeutic targets by dissecting these mechanisms.

Main Methods:

  • Literature review focusing on inflammation-hemostasis interplay in cancer.
  • Analysis of mechanisms involving inflammatory cells, thrombin-fibrinogen axis, and protease-activated receptor-1.
  • Synthesis of current knowledge on the role of these systems in tumorigenesis, growth, and metastasis.

Main Results:

  • Inflammation and hemostasis exhibit bidirectional crosstalk, essential for normal functions but co-opted by cancer.
  • This interplay promotes multiple stages of cancer, including initiation, growth, and metastasis.
  • Specific interactions involve inflammatory cells activating hemostasis and hemostatic components regulating inflammation.

Conclusions:

  • The integrated inflammatory and hemostatic systems significantly contribute to cancer pathobiology.
  • Dissecting these cooperative mechanisms fills knowledge gaps in cancer understanding.
  • Targeting the inflammation-hemostasis axis offers potential for novel cancer therapies.
