Autophagic cell death can be conveniently studied in Dictyostelium discoideum, an exceptionally favorable model not only because of its well-known genetic and experimental advantages but also because in Dictyostelium there is no apoptosis machinery that could interfere with nonapoptotic cell death. Moreover, autophagic cell death in Dictyostelium can be dissociated into a starvation-induced sensitization stage, during which autophagy is induced, and a death induction stage. We show here how to demonstrate, assess and analyze this autophagic cell death. This can be studied in vivo during the development of Dictyostelium, and in vitro, using modifications of the monolayer technique of Rob Kay et al. Methods to follow this autophagic cell death qualitatively and quantitatively are reported.

A time-dependent bidirectional association between folate and lung cancer deaths among a national cohort.

Eur J Cancer Prev

The relationship between folate and the risk of cancer remains undetermined partially due to the dynamic changes in folate intakes at the population level caused by folic acid fortification implemented in the USA and other countries. To control for the interference from fortification, we assessed the relationship between folate and lung cancer death (LCD) risk among a national cohort established years before folic acid fortification. We followed up 14 528 adults aged 19 years or older who participated in the National Health and Nutrition Examination Survey (1988-1994) on average for 14 years.

Comprehensive Analysis of Bulk RNA-Seq and Single-Cell RNA-Seq Data Unveils Sevoflurane-Induced Neurotoxicity Through SLC7A11-Associated Ferroptosis.

Sevoflurane's potential impact on cognitive function and neurodevelopment, especially in susceptible populations such as infants and the elderly, has raised widespread concern. This study focuses on how sevoflurane induces ferroptosis in astrocytes and identifies solute carrier family 7 member 11 (SLC7A11) as a mediator of ferroptosis, providing new insights into sevoflurane-related neurotoxic pathways. We analysed single-cell sequencing (scRNA-seq) data from sevoflurane-exposed mice and control mice, supplemented with bulk RNA-seq data, to assess gene expression alterations.

Targeted Activation of Programmed Cell Death Pathways by Optogenetics.

Regulated cell death is an important biological process by which an organism removes unwanted, malignant, or infected cells. Although it has become clear that different forms of regulated cell death exist, it remains difficult to compare their consequences at the cellular and tissue level as they are induced by different stimuli and proceed with different kinetics. Moreover, it was so far difficult to target and induce cell death in selected cells within cell populations or complex tissues without affecting its neighbors.

Background: Premature ovarian insufficiency (POI) is a refractory disease that severely affects female fertility. The PERK/eIF-2α/ATF4/CHOP pathway is one of the classical pathways involved in the unfolded protein response to endoplasmic reticulum stress by regulating protein synthesis and promoting apoptosis. This study aimed to investigate the functional role and mechanism of human umbilical cord mesenchymal stem cells (hUCMSCs) in the POI animal model through the PERK/eIF-2α/ATF4/CHOP pathway.

Importance: Progressive disease (PD) in patients treated with immune checkpoint inhibitors (ICIs) varies widely in outcomes according to the Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. Efforts to modify RECIST for ICI treatment have not resolved the heterogeneity in PD patterns, posing a clinical challenge.
