Summary
The cytoskeleton, particularly microfilaments, is crucial for mechanical stress-induced autophagy. These findings highlight microfilaments as key players in mechanotransduction signaling pathways.
Area of Science:
- Cell Biology
- Mechanobiology
- Biochemistry
Background:
- The cytoskeleton plays a vital role in cellular mechanical signal transduction and autophagy.
- Direct evidence linking the cytoskeleton to mechanical stress-induced autophagy remains limited.
Purpose of the Study:
- To investigate the role of the cytoskeleton in compressive force-induced autophagy in human cell lines.
- To elucidate the specific contributions of microfilaments and microtubules to this process.
Main Methods:
- Utilized small chemical molecules to inhibit and activate cytoskeletal polymerization.
- Quantified changes in autophagosome numbers in response to mechanical stress.
- Analyzed the roles of microfilaments and microtubules in mechanotransduction.
Main Results:
- Cytoskeletal microfilaments are essential for alterations in autophagosome numbers under mechanical stress.
- Microtubules exhibit an auxiliary role in mechanical stress-induced autophagy.
- Microfilaments' intrinsic properties and distribution significantly contribute to compression-induced autophagy.
Conclusions:
- Microfilaments are core components of mechanotransduction signals involved in autophagy.
- The cytoskeleton, especially microfilaments, is indispensable for responding to mechanical forces through autophagy.

4.2K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

01:36Delivery Pathways to the Lysosome
6.2K
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.

In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

3.4K
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.

00:50Anaphase Promoting Complex
2.8K
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

5.8K
The cytoskeletal architecture can be studied using different microscopic and biochemical techniques. Electron microscopy was instrumental in discovering the cytoskeletal architecture around the 1960s, which allowed obtaining structural information at a high-resolution level. However, the sample preparation procedure often limits this ability in biological samples. Several protocols have been developed over the years to optimize sample preparation. In one of the protocols known as rotary...

01:32Export of Misfolded Proteins out of the ER
3.5K
After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...
