Summary: Since the Nobel Prize was awarded more than twenty years ago for discovering the core apoptotic pathway in C. elegans, researchers around the world have conducted extensive research on apoptosis and various other forms of regulated cell death. Although there are still many aspects of regulated cell death that need to be clarified in specific cell subtypes and disease conditions, the last decade has seen the description of multiple cell death modalities, some of which have been successfully used in clinical therapy. To keep research into cell death alive, francophone researchers from several institutions in France and Belgium established the French Cell Death Research Network (FCDRN), which is at the forefront of emerging topics in cell death research. These research efforts will enhance our mechanistic knowledge of regulated cell death and its therapeutic applications in the coming years.

Summary: This study evaluated the transcriptomic profile of cell death pathways in bladder cancer patients and found that patients with high cell-death index (CDI) had a higher risk of mortality. These high-risk patients also exhibited an immunoevasive tumor microenvironment characterized by increased tumor-associated macrophage infiltration and expression of immune checkpoints. These findings provide important clinical and immunological insights for the management of bladder cancer.

Summary: The human body is complex and comprises various living cells and extracellular material forming tissues, organs, and organ systems. While most human cells turnover regularly, postmitotic nerve cells have the exceptional ability to regenerate and sustain throughout an individual's life to safeguard the central nervous system's functioning. Neurodegenerative diseases, such as Parkinson's and Alzheimer's disease, result from factors like oxidative stress, cell death, and neuroinflammation, causing neuronal degradation and impacting the quality of life for millions worldwide.

Summary: This paper proposes a new perspective on the regulation of programmed cell death (PCD) in developing systems based on epigenetics. It challenges the traditional view that PCD is solely controlled by specific gene-encoded signals, arguing that the signals and local tissue interactions responsible for embryonic tissue growth and differentiation play a significant role in PCD. The study suggests that cells retain an epigenetic profile sensitive to DNA damage, resulting in their subsequent elimination.

Summary: This study reveals the dual role of PRMT1-mediated RIP3 methylation in necroptotic cancer cell death and tumor immune escape. PRMT1 methylates RIP3 and inhibits its interaction with RIP1, thereby suppressing necrosome complex formation and necroptosis activation. The protein levels of PRMT1 and RIP3(ADMA) are positively correlated in cancer tissues and both serve as valuable prognostic markers for colon cancer.

Summary: By conducting bibliometric analyses, this study explores the research trends and hotspots of Pin1 and cell death. The results indicate that the research on Pin1 and cell death has been increasing annually since 2001, but growth after 2014 appears to be stagnant. The cooperation between core institutions needs to be strengthened, and recently, Fujian Medical University in China has emerged as the institution with the highest citation count. Further research is required to understand the role of Pin1 in cell death and to identify new research hotspots. Future studies are likely to focus on disease treatment using Pin1 inhibitors, before breakthroughs are made in understanding the molecular mechanisms or signaling pathways.

Summary: Irreversible electroporation (IRE) can cause apoptosis, necrosis, oncosis, or pyroptosis. The mode of cell death following IRE is determined by intracellular ATP levels. Cell death after IRE is insensitive to caspase inhibition and is correlated with ATP loss, which cannot be rescued by ATP supplementation.

Summary: Programmed cell death (PCD) is a universal process that regulates cellular homeostasis and plays a crucial role in disease conditions, including cancer. Apoptosis is a major PCD, but cancer cells develop resistance to it, necessitating the search for alternative forms of programmed cell death such as paraptosis. Paraptosis is characterized by vacuolation and damage to cellular structures and has potential therapeutic implications in cancer treatment.

Summary: Cell death is a normal and essential component of development and homeostasis, but dysregulation of this process underlies most human diseases. Autophagy is a process mediated by the formation of double membrane vesicles, which allows cells to survive stresses and may also mediate cell death during development and pathogenesis.

Summary: This study identified a novel 21-gene cell death signature in lung cancer patients, which significantly correlates with patient survival. Patients with higher expression of this genomic signature were found to have increased risk of early mortality. Additionally, the study revealed perturbations in cytokine expression, immune cell infiltration, and immune checkpoint molecule expression in high-risk patients, suggesting a potential for personalized immunotherapies targeting these pathways.

Summary: This study investigated the cell-specific expression of Rubicon in postmortem brain samples from AD patients and 5xFAD mice and its impact on amyloid beta burden. Increased Rubicon levels were found in AD-hiPSCs and postmortem samples. In AD transgenic mice lacking Rubicon, intensified amyloid beta burden was observed. In neuroblastoma cells, the absence of Rubicon led to increased APP/amyloid beta secretion.

Summary: The burden of Alzheimer's disease and related dementia (ADRD) is projected to be disproportionally higher in low-middle-income countries (LMICs). However, there is a lack of representation of LMICs in ADRD clinical trial platforms. This study found that only 11.6% of ADRD clinical trials were conducted in emerging economies (upper-middle income [9.6%] and low-middle income [2.0%]). The limitations for trial implementation in LMICs include limited financial resources, low industry presence, regulatory obstacles, and operational barriers.

Summary: Epidemiological studies find that having a history of cancer or Alzheimer's Disease (AD) can protect against the development of the other. The underlying mechanism for this mutual protection is unknown. However, research suggests that PBMCs of individuals with aMCI and AD have increased susceptibility to oxidative cell death, while a history of cancer is associated with increased resistance to cell death caused by oxidative stress.

Summary: This systematic review evaluated the efficacy of rapalogues in age-related musculoskeletal disorders (MSKD) in humans. While some studies have assessed the effects of rapamycin and rapalogues on bone, muscle, and joints, there is considerable variability in subjects' age, inclusion criteria, and drug administration protocols. The evidence supporting their use is still limited, and further research is needed to explore the clinical implications on osteoporosis, sarcopenia, or osteosarcopenia.
