Tyramide Signal Amplification for the Immunofluorescent Staining of ZBP1-dependent Phosphorylation of RIPK3 and MLKL After HSV-1 Infection in Human Cells.

The kinase Receptor-interacting serine/threonine protein kinase 3 (RIPK3) and its substrate mixed lineage kinase domain-like (MLKL) are critical regulators of necroptosis, an inflammatory form of cell death with important antiviral functions. Autophosphorylation of RIPK3 induces phosphorylation and activation of the pore-forming executioner protein of necroptosis MLKL. Trafficking and oligomerization of phosphorylated MLKL at the cell membrane results in cell lysis, characteristic of necroptotic cell death.

Association of Cell Death Markers With Tumor Immune Cell Infiltrates After Chemo-Radiation in Cervical Cancer.

Unlabelled: Irradiation induces distinct cellular responses such as apoptosis, necroptosis, iron-dependent cell death (a feature of ferroptosis), senescence, and mitotic catastrophe. Several of these outcomes are immunostimulatory and may represent a potential for immunogenic type of cell death (ICD) induced by radiotherapy triggering abscopal effects. The purpose of this study is to determine whether intra-tumoral ICD markers can serve as biomarkers for the prediction of patient's outcomes defined as the metastasis status and survival over a 5-year period.

Distinct Transcriptional Programs in Ascitic and Solid Cancer Cells Induce Different Responses to Chemotherapy in High-Grade Serous Ovarian Cancer.

Unlabelled: High-grade serous ovarian cancer (HGSOC) is responsible for the largest number of ovarian cancer deaths. The frequent therapy-resistant relapses necessitate a better understanding of mechanisms driving therapy resistance. Therefore, we mapped more than a hundred thousand cells of HGSOC patients in different phases of the disease, using single-cell RNA sequencing.

Innovative mouse models for the tumor suppressor activity of Protocadherin-10 isoforms.

Background: Nonclustered mouse protocadherin genes (Pcdh) encode proteins with a typical single ectodomain and a cytoplasmic domain with conserved motifs completely different from those of classic cadherins. Alternative splice isoforms differ in the size of these cytoplasmic domains. In view of the compelling evidence for gene silencing of protocadherins in human tumors, we started investigations on Pcdh functions in mouse cancer models.
