Summary
Autophagy, a cellular process, degrades damaged components. Its complex role in cancer, promoting survival or suppression, offers new therapeutic targets for anticancer drug development.
Area of Science:
- Cell Biology
- Molecular Biology
- Oncology
Background:
- Autophagy is a fundamental cellular degradation pathway involving autophagosomes and lysosomes.
- This process is crucial for cellular homeostasis, responding to stress like nutrient deprivation.
- Dysregulation of autophagy is implicated in various human diseases, notably cancer.
Purpose of the Study:
- To review recent advancements in understanding the intricate mechanisms of autophagy.
- To explore the dual role of autophagy in cancer: promoting tumor cell survival and suppressing tumor initiation.
- To discuss the development of targeted therapies that modulate autophagy for cancer treatment.
Main Methods:
- Literature review of recent scientific publications on autophagy and cancer.
- Analysis of signaling pathways regulating autophagy.
- Examination of clinical developments in autophagy-modulating anticancer therapies.

Autophagy
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,...

Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Autophagic 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.

Delivery 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...

Cellular 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...
