Background/Objectives:
Regulated cell death (RCD), a process that relies on a series of molecular mechanisms, can be targeted to eliminate superfluous, irreversibly damaged, and potentially harmful cells. In this research, we want to better understand how the cell death pathway contributes to cancer therapy.
Methods:
We studied 1150 cancer cells in the Dependency Map (DepMap) database for 12 distinct cell death pathways and assessed their gene essentialities. Genes which are essential in 90% or more of cancer cell lines are called always essential, or partial essential if falling into (10%, 90%), or rare essential if they are essential in less than 10% of cancer cell lines.
Results:
Overall, among these 12 cell death pathways, 23, 47, and 549 genes were classified as always essential, partial essential, and rare essential, respectively. In two cell death pathways, Parthanatos, and Pyroptosis, all genes were rare essential. Among the other ten cell death pathways, Apoptosis, Autosis, Necroptosis, Efferocytosis, Ferroptosis, Mitotic cell death, Autophagy, Lysosome-dependent cell death, MPT-driven necrosis and Immunogenic, there are (10, 1, 13, 6, 3, 9, 11, 1, 1, 0) partial essential genes, and (2, 0, 3, 1, 1, 13, 4, 0, 0, 1) always essential genes.
Conclusions:
These cell death pathway essential genes could be viable targets for therapeutic drug development for cancer therapies.

Background:
- Regulated cell death (RCD) involves molecular mechanisms to eliminate harmful cells.
- Targeting RCD is a promising strategy in cancer therapy.
Purpose of the Study:
- To investigate the role of cell death pathways in cancer therapy.
- To identify essential genes within various RCD pathways.
Main Methods:
- Analysis of 1150 cancer cell lines from the Dependency Map (DepMap) database.
- Assessment of gene essentialities across 12 distinct cell death pathways.
- Classification of genes as always essential, partial essential, or rare essential.
Main Results:
- Identified 23 always essential, 47 partial essential, and 549 rare essential genes across 12 RCD pathways.
- Parthanatos and Pyroptosis pathways exclusively contained rare essential genes.
- Specific counts of partial and always essential genes were found in other pathways like Apoptosis and Necroptosis.
Conclusions:
- Essential genes within cell death pathways represent potential therapeutic targets.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
