Summary
This summary is machine-generated.Glucose starvation causes abnormal disulfide buildup in solute carrier family 7 member 11 (SLC7A11)<sup>high</sup> cells, triggering disulfidptosis. This cell death pathway shows promise for cancer diagnosis and therapy.
Area Of Science
- Biochemistry
- Cell Biology
- Oncology
Background
- Aberrant accumulation of intracellular disulfides is observed in specific cancer cell types.
- Solute carrier family 7 member 11 (SLC7A11)<sup>high</sup> cells are particularly susceptible to disulfide stress.
- Disulfidptosis, a form of programmed cell death, is induced by excessive disulfide buildup.
Purpose Of The Study
- To investigate the mechanism linking glucose starvation, SLC7A11 expression, and disulfidptosis.
- To explore the potential of disulfidptosis as a therapeutic target in cancer treatment.
- To understand the role of intracellular disulfide accumulation in cancer progression.
Main Methods
- Cell culture under glucose-deprived conditions.
- Analysis of intracellular disulfide levels using redox-sensitive probes.
- Assessment of cell viability and death pathways, including disulfidptosis.
- Evaluation of SLC7A11 expression levels in various cancer cell lines.
Main Results
- Glucose starvation significantly increased intracellular disulfide accumulation in SLC7A11<sup>high</sup> cells.
- This accumulation directly triggered disulfidptosis, leading to cell death.
- SLC7A11<sup>high</sup> cells exhibited a distinct vulnerability to disulfidptosis induction.
- The findings highlight a novel mechanism of cancer cell death.
Conclusions
- Disulfidptosis is a critical cell death pathway induced by disulfide stress in SLC7A11<sup>high</sup> cells under glucose starvation.
- Targeting disulfidptosis presents a promising strategy for cancer therapy.
- Understanding this pathway could improve tumor diagnosis and treatment modalities.

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
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...
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
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...
