Cell-matrix's Response to Mechanical Forces01:13

Cell-matrix's Response to Mechanical Forces

In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

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...
What is Cancer?02:12

What is Cancer?

Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of patients who died from...
Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Area of Science:

  • Biophysics
  • Cancer Biology
  • Computational Biology

Background:

  • Tumor growth and metastasis involve complex cellular processes.
  • Mechanical properties of cells play a role in cancer progression.

Purpose of the Study:

  • To investigate the mechanical basis of tumor growth and metastasis.
  • To model the impact of cell compliance and intercellular binding on cancer progression.

Main Methods:

  • Utilized a 3D discrete cell model.
  • Simulated cell behavior based on mechanical properties like compliance and intercellular binding.

Main Results:

  • Increased cell compliance in cancer cells leads to significantly faster growth rates compared to healthy cells.
  • Alterations in intercellular binding influence tumor malignancy and metastatic potential.
  • Mechanical changes in cancer cells are identified as a primary driver of uncontrolled division and migration.

Conclusions:

  • Mechanical properties of cancer cells are a proximate cause of uncontrolled division and migration.
  • Biochemical factors likely drive cancer progression through these mechanical mechanisms.
