The Tumor Microenvironment02:17

The Tumor Microenvironment

6.3K
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...

Metastasis02:30

Metastasis

5.4K
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...

The Extracellular Matrix01:29

The Extracellular Matrix

10.7K
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...

Liver Regeneration01:24

Liver Regeneration

4.1K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Area of Science:

  • Oncology
  • Cancer Biology
  • Extracellular Matrix Research

Background:

  • Colorectal cancer (CRC) liver metastasis is a primary cause of cancer-related mortality.
  • The tumor microenvironment, specifically the extracellular matrix (ECM), is crucial in CRC metastasis and treatment resistance.
  • Understanding the hepatic ECM's role is vital for developing effective therapeutic interventions.

Purpose of the Study:

  • To provide a comprehensive understanding of the ECM's role in colorectal liver metastasis.
  • To explore potential therapeutic targets within the ECM for colorectal cancer treatment.
  • To review the influence of the hepatic ECM on CRC cell metastatic behavior and chemoresistance.

Main Methods:

  • Review of clinical and basic research findings on ECM and colorectal liver metastasis.
  • Analysis of ECM's role in regulating cancer cell fate and metastatic behavior.
  • Examination of ECM remodeling, stiffening, and signaling pathways in chemoresistance.

Main Results:

  • The ECM influences cancer cell fate and promotes CRC liver metastasis through specific molecular interactions.
  • The hepatic ECM 'fingerprint' dictates the metastatic behavior of colorectal cancer cells.
  • ECM remodeling, including stiffening and activated signaling, contributes to chemoresistance in the metastatic niche.

Conclusions:

  • The ECM is a critical determinant of colorectal liver metastasis and chemoresistance.
  • Targeting ECM-mediated mechanisms presents a promising avenue for novel therapeutic strategies.
  • Further understanding of these interactions is essential for improving outcomes for CRC patients.
