The Extracellular Matrix

12.2K
Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

Extracellular Matrix

5.4K
Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...

Tumor Progression02:07

Tumor Progression

7.4K
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...

Nucleosome Remodeling02:54

Nucleosome Remodeling

11.1K
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.
Nucleosome remodeling complex
Eukaryotic cells have specialized enzymes called ATP-dependent nucleosome remodeling enzymes. These enzymes...

Bone Remodeling01:40

Bone Remodeling

40.4K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Area of Science:

  • Cancer Biology
  • Tumor Microenvironment
  • Extracellular Matrix Remodeling

Background:

  • Cancer is a systemic disease involving complex interactions between neoplastic and stromal cells.
  • The extracellular matrix (ECM), a non-cellular component, is often dysregulated in tumor microenvironments.
  • The ECM's role was traditionally viewed as passive, primarily structural, and a barrier to metastasis.

Purpose of the Study:

  • To review and discuss the multifaceted role of the ECM in cancer biology.
  • To highlight how ECM remodeling actively influences cancer cell behaviors and progression.
  • To explore the ECM's impact on epithelial and stromal cell interactions within the tumor microenvironment.

Main Methods:

  • Literature review of existing research on ECM remodeling in cancer.
  • Synthesis of evidence demonstrating ECM's active role beyond a physical barrier.
  • Analysis of mechanisms by which abnormal ECM affects cancer progression.

Main Results:

  • ECM remodeling significantly influences cancer cell behaviors, contrary to previous assumptions.
  • Abnormal ECM contributes to cancer progression through mechanisms like hypoxia and immune cell modulation.
  • ECM remodeling promotes epithelial-mesenchymal transition and cell transformation.

Conclusions:

  • The ECM is a dynamic and critical component in cancer progression, not merely a passive bystander.
  • Understanding ECM remodeling is crucial for developing novel cancer therapies.
  • Targeting ECM interactions presents promising prospects for future cancer treatment strategies.
