LDH Cytotoxicity Assay Kit: Workflow and QC
2026-09-24
The LDH Cytotoxicity Assay Kit measures LDH released into culture medium to support endpoint cell cytotoxicity measurement and cell damage quantification. It is useful for comparing membrane damage across treatment groups, but it does not identify a specific death pathway or replace mechanism-focused assays.

Viral RIPK3 Degradation Shapes Orthopoxvirus Inflammation
2026-09-23
Liu et al. identify a class of orthopoxvirus proteins that recruits host ubiquitin machinery to degrade RIPK3, suppressing necroptosis and altering viral replication and disease. The study connects this immune-evasion mechanism to host genotype and viral evolution, while highlighting why cell-death pathways must be distinguished when designing experiments.

CA800-PR Disrupts Golgi Signaling in HR+ Breast Cancer
2026-09-22
The reference study reports that the tumor-targeted heptamethine cyanine dye CA800-PR combines near-infrared imaging with selective suppression of progesterone receptor expression in HR+ breast cancer models. Its association with Golgi fragmentation, apoptosis, cytokine production, and M1-type macrophage enrichment suggests a therapeutic strategy distinct from conventional endocrine inhibition, while further validation is needed before clinical translation.

Large-Scale Gastruloid Arrays for Phenotype Screening
2026-09-22
Jan and colleagues developed an indexed magnetic microraft array that supports image-based analysis and automated sorting of individual human gastruloids at scale. The platform distinguished euploid from aneuploid gastruloids through DNA-area measurements and spatial-patterning gene expression, creating a practical route for single-structure developmental screening.
