E2F regulation of endocycles in hepatocytes

Validation Score: 0.850 Price: $0.50 lineage-specific cre mice, liver hepatocytes Status: proposed

What This Experiment Tests

Validation experiment designed to validate causal mechanisms targeting E2F1, E2F2, E2F3, E2F7, E2F8 in lineage-specific cre mice, liver hepatocytes. Primary outcome: genome ploidy levels

Description

This experiment investigated the role of E2F transcription factors in regulating endocycles in liver hepatocytes, the second major endocycling tissue in mammals. Using the same lineage-specific cre mouse system, researchers examined how genetic ablation of canonical E2F activators (E2F1, E2F2, E2F3) versus atypical E2F repressors (E2F7, E2F8) affects hepatocyte ploidy. Hepatocytes naturally undergo endoreduplication during liver development and regeneration, making them an important model for studying endocycle regulation. The study measured genome ploidy changes following selective knockout of different E2F family members to understand their opposing roles in endocycle control.
