Summary
Cells use mechanostasis to balance mechanical forces, but abnormal forces trigger apoptosis, potentially causing disease. Understanding these pathways may lead to new treatments.
Area of Science:
- Cellular biology
- Biophysics
- Physiology
Background:
- Mechanostasis is the cellular process of maintaining equilibrium against mechanical forces.
- Normal mechanical forces promote cell proliferation and tissue development.
- Abnormal forces can trigger compensatory apoptotic mechanisms, contributing to disease.
Purpose of the Study:
- To provide an overview of the links between apoptosis signaling and mechanotransduction.
- To identify potential clinical applications for treating diseases by targeting mechanically-linked apoptotic pathways.
Main Methods:
- Literature review of mechanotransduction and apoptosis signaling pathways.
- Analysis of the interplay between mechanical forces and cellular apoptotic responses.
Main Results:
- Mechanotransduction pathways are tightly regulated and influence cellular responses to mechanical stress.
- Pro- and anti-apoptotic signaling are interconnected with mechanotransduction pathways.
- Abnormal mechanical forces can initiate disease processes through apoptotic dysregulation.
Conclusions:
- Understanding the mechanobiology of apoptosis is crucial for comprehending disease development.
- Targeting mechanically-regulated apoptotic pathways offers potential therapeutic strategies for various diseases.

01:30Apoptosis
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
01:30Overview of Cell Death
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...

01:18Autophagic Cell Death
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:22Cellular Injury V: Apoptosis and Autophagy
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
01:16Necrosis
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...
