A team of researchers has identified a previously unknown vulnerability in KRAS-mutated pancreatic cancer cells, making them susceptible to necroptosis. Blocking the tumor cells' defense mechanism by inhibiting caspase-8 leads to significant cell death and reduced tumor growth.
A recent study reveals that MLKL activation causes direct damage to mitochondria, impairing energy production and leading to functional decline in hematopoietic stem cells. In contrast, deletion or inhibition of MLKL significantly alleviates these defects, suggesting a post-transcriptional mechanism driving HSC aging.
A team of researchers uses CRISPR gene editing to eliminate cells with amplified oncogenes, reducing tumour growth and increasing animal survival. The study offers a promising approach for precision therapies in resistant cancers.
Researchers explore ZBP1-mediated programmed cell death, its mechanisms, and therapeutic strategies for systemic diseases. The review also discusses ZBP1's involvement in various types of cell death, including apoptosis, necroptosis, pyroptosis, and ferroptosis.
Researchers have characterised how dying cells contribute to the body's regeneration process, suggesting a new mechanism for tissue repair. The study found that cells released from necrosis play a role in signaling the production of other cells involved in controlling natural cell death and inflammation.
A new study from Aarhus University found that acute kidney injury causes significant cell death in kidneys, which then spreads to healthy tissue over several days. This finding may increase the risk of patients developing chronic kidney damage and highlights the need for timely intervention measures.
Researchers found that necroptosis promotes metastasis in breast cancer models, and blocking it leads to inhibition of metastasis. Necroptosis may be a key factor in tumor progression, and targeting its regulators could be critical for mitigating metastasis.
A Brazilian group developed a peptide called Rb4 that triggers necrosis in murine melanoma cells and inhibits the viability of human cancer cells. In mice, Rb4 reduced lung metastasis and slowed subcutaneous melanoma growth, increasing survival by 25%.
Researchers at Okayama University have created a new method to kill cancer cells using light-activated protein AR3, reducing the risk of adverse reactions. The approach uses green light to trigger apoptosis in targeted cells, offering a promising alternative to conventional treatments.
A preclinical study identified a protein complex critical for regulating apoptosis and necroptosis. Inhibiting this complex may help prevent excessive cell death and tissue damage associated with heart attacks, autoimmune disorders, and COVID-19. Researchers believe that targeting the PPP1R3G/PP1γ pathway could lead to new treatments f...
Researchers found that calcium ions trigger the exposure of phosphatidylserine on the surface of necrotic cells, activating an enzyme that promotes their clearance. This process is crucial for maintaining body health and preventing tissue damage caused by unremoved dead cells.
Researchers at Université de Genève and University of Lyon identified deoxydihydroceramide as the molecule causing tissue necrosis. Inhibiting its synthesis reduced tissue damage by 30% in mice, suggesting a new model for treating heart attacks and strokes.
Scientists from Tokyo University of Science have discovered exactly how cell-free DNA (cfDNA) is generated, revealing its crucial role in tumor progression. The study's findings suggest that cfDNA can be targeted using DNase1L3, a novel molecule to prevent tumor metastasis and thrombosis.
A study using worms has discovered the mechanisms involved when multicellular organisms die, particularly as a result of old age. The research found that death spreads through the organism via cellular necrosis, triggered by calcium release, leading to muscle hypercontraction and rigor mortis.
Researchers at MIT have identified ALKBH7 as a key protein involved in programmed necrosis, a cell death pathway that can help prevent cancer cells from surviving DNA damage. By mimicking the effects of this protein, drugs may be able to induce necrosis in resistant cancer cells, providing a new potential target for cancer treatment.
A recent Weizmann Institute study has discovered that caspase 8 signaling enzymes, which were previously thought to only induce programmed cell death, can also activate an entirely different process in certain cells - causing inflammation more directly. This finding highlights the need for further research into the signals transmitted ...
A new study reveals that protein SRP-6 can regulate cell death and potentially halt the progression of cancer, stroke, and heart disease. The research team discovered that SRP-6 can target the lysosome, protecting cells from stress and injury.
Research by Corbett et al. reveals that islet cells are susceptible to necrosis when exposed to interleukin-1, a cytokine that triggers b-cell release of HMGB1. This process contributes to the development of diabetes.
Scientists have identified a key trigger of neuron death in Parkinson's disease, stroke, and traumatic brain injury, which can be prevented by blocking its release from mitochondria. The study found that preventing PARP activation and blocking AIF release protects cells from dying.
