Abstract

Insights

Autophagy supports cancer cell metabolism and growth, especially in BRAF-driven tumors. Inhibiting autophagy alongside BRAF may overcome treatment resistance and improve cancer therapy outcomes.

Area of Science:

  • Oncology
  • Cell Biology
  • Metabolic Research

Background:

  • Autophagy plays a crucial role in maintaining mitochondrial metabolism and homeostasis in cancer.
  • BRAF inhibitors are effective against BRAF-mutated cancers but resistance often emerges.
  • Resistance to BRAF inhibitors is linked to increased mitochondrial biogenesis and oxidative phosphorylation.

Purpose of the Study:

  • To review the role of autophagy in BRAF-driven malignancies.
  • To explore the potential of combining autophagy inhibition with BRAF inhibition to overcome resistance.
  • To highlight autophagy as a therapeutic target in BRAF-mutated cancers.

Main Methods:

  • Review of existing metabolomic and cancer research data.
  • Analysis of mechanisms underlying BRAF inhibitor resistance.
  • Integration of findings on autophagy's role in mitochondrial function.

Main Results:

  • Autophagy is essential for mitochondrial metabolism and homeostasis in cancer.
  • BRAF-driven tumors rely on autophagy for growth and survival.
  • Increased mitochondrial activity contributes to resistance against BRAF inhibitors.

Conclusions:

  • Autophagy inhibition may be a potent strategy in BRAF-driven cancers.
  • Combining BRAF and autophagy inhibition could overcome treatment resistance.
  • Targeting autophagy presents a promising avenue for improving cancer therapy.

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...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

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,...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
