Targeted Cancer Therapies02:57

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.
There are several types of targeted therapies against specific...

Delivery Pathways to the Lysosome01:36

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...
Autophagy01:27

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,...
Autophagic Cell Death01:18

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.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and pro-apoptotic...
Cellular Injury V: Apoptosis and Autophagy01:22

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...

Area of Science:

  • Cell Biology
  • Oncology
  • Biochemistry

Background:

  • Autophagy is a fundamental cellular recycling mechanism vital for homeostasis, particularly during metabolic stress.
  • In cancer, autophagy exhibits a dual role, potentially suppressing tumors by preventing inflammation and genetic instability, or promoting them by providing energy during metabolic stress.
  • The mTOR pathway is a key regulator of autophagy, and drugs targeting the PI3K/Akt/mTOR axis may influence autophagy, but its precise role in antitumor effects or drug resistance is unclear.

Purpose of the Study:

  • To review the multifaceted role of autophagy in human cancers.
  • To explore the potential of modulating autophagy as an anticancer therapeutic strategy.
  • To highlight the need for improved methods to measure autophagy in clinical settings.

Main Methods:

  • Literature review focusing on the role of autophagy in cancer.
  • Analysis of preclinical data on autophagy modulation in cancer therapy.
  • Discussion of existing and potential therapeutic strategies targeting autophagy.

Main Results:

  • Autophagy's dual role in cancer (tumor promotion and suppression) is complex and context-dependent.
  • Inhibition of autophagy by drugs like chloroquine can enhance the efficacy of certain anticancer agents in preclinical models.
  • The precise contribution of autophagy to the efficacy or resistance of anticancer drugs requires further investigation.

Conclusions:

  • Autophagy represents a promising novel target for anticancer therapy.
  • Further research is needed to elucidate the precise clinical roles of autophagy induction and inhibition in cancer treatment.
  • Development of robust methods for measuring autophagy in clinical samples is crucial for advancing this field.
