Insights

Melanoma cells resist apoptosis by activating the unfolded protein response (UPR) and increasing protein folding capacity. Targeting UPR and endoplasmic reticulum (ER) stress offers potential melanoma therapies.

Area of Science:

  • Oncology
  • Cell Biology
  • Molecular Biology

Background:

  • Melanoma cells exhibit resistance to apoptosis.
  • Endoplasmic reticulum (ER) stress can trigger apoptosis.
  • The unfolded protein response (UPR) is a key survival mechanism in cancer cells.

Purpose of the Study:

  • To review how melanoma cells evade ER stress-induced apoptosis.
  • To explore therapeutic strategies targeting ER stress in melanoma.

Main Methods:

  • Literature review of cellular survival mechanisms in melanoma.
  • Analysis of UPR signaling pathways.
  • Examination of therapeutic interventions targeting ER stress.

Main Results:

  • Melanoma cells utilize UPR to resist ER stress-induced apoptosis.
  • Oncogene activation suppresses apoptosis.
  • Upregulation of ER chaperones and BCL-2 family proteins enhances cell survival.

Conclusions:

  • Modulating UPR signaling and inducing ER stress are potential therapeutic strategies for melanoma.
  • Targeting protein folding machinery and ER stress pathways may offer new treatment avenues.

Endoplasmic Reticulum

The Endoplasmic Reticulum (ER) in eukaryotic cells is a substantial network of interconnected membranes with diverse functions, from calcium storage to biomolecule synthesis. A primary component of the endomembrane system, the ER manufactures phospholipids critical for membrane function throughout the cell. Additionally, the two distinct regions of the ER specialize in the manufacture of specific lipids and proteins.

The Endoplasmic Reticulum

The endoplasmic reticulum or ER makes up for more than half of the membranes in a cell and accounts for 10% of total cell volume. It is also the primary protein and lipid synthesis factory for most cell organelles, such as the Golgi apparatus, lysosomes, secretory vesicles, and the plasma membrane. Despite being the most extensive and functionally complex subcellular organelle, ER was the last to be discovered. After years of deliberation, Keith Porter and George Palade in the year 1954,...

Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Directing Proteins to the Rough Endoplasmic Reticulum01:34

Directing Proteins to the Rough Endoplasmic Reticulum

The organelle-specific signaling sequences direct proteins synthesized in the cytosol to their final destination like ER, mitochondria, peroxisomes, etc. Some of the proteins directed to ER are then trafficked via vesicles to other organelles within the cell or the extracellular environment through the Golgi complex. For example, the rough ER synthesizes soluble proteins for transportation to the lysosomes or secretion out of the cell. It can also synthesize transmembrane proteins that can...

Persuasion Strategies

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Gene Therapy00:59

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...
