Summary
Selective autophagy, a process for targeted cellular cleanup, is crucial for homeostasis and stress response in yeast and humans. This review explores selective autophagy mechanisms and their links to diseases like cancer and neurodegeneration.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Autophagy is a conserved cellular process involving the degradation of cytoplasmic components via lysosomes/vacuoles.
- It plays vital roles in maintaining cellular homeostasis, adapting to stress, and regulating development and immunity.
- Dysregulation of autophagy is implicated in various human diseases, including cancer, neurodegeneration, and myopathies.
Purpose of the Study:
- To review the mechanisms and roles of selective autophagy in yeast.
- To highlight potential connections between yeast selective autophagy pathways and human diseases.
- To discuss selective autophagy types observed exclusively in higher eukaryotes.
Main Methods:
- Literature review of studies on selective autophagy, primarily using yeast Saccharomyces cerevisiae as a model.
- Analysis of mechanisms for selective targeting of proteins, protein complexes, and organelles.
- Comparison of selective autophagy pathways across different eukaryotic organisms.
Main Results:
- Autophagy can selectively eliminate specific cellular components, challenging the notion of it being solely non-selective.
- Studies in yeast have elucidated key mechanisms of selective autophagy.
- Evidence suggests conserved pathways and potential links to human pathologies.
Conclusions:
- Selective autophagy is a critical regulatory mechanism with significant implications for cellular health.
- Understanding yeast selective autophagy provides insights into its role in human disease.
- Further research is needed to fully elucidate the diversity and functions of selective autophagy in higher eukaryotes.

01:27Autophagy
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
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.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

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.

01:33Overview of Secretory Vesicles
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

01:28Yeast Signaling
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
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...
