CCDC134 serves a crucial role in embryonic development

Area of Science:

• Developmental Biology
• Immunology
• Molecular Biology

Background:

• Coiled-coil domain containing 134 (CCDC134) is a secreted protein with potential roles in immune responses and antitumor activity.
• CCDC134 may also regulate human activation/deficiency 2a and influence the p300-CBP-associated factor complex's acetyltransferase activity.

Purpose of the Study:

• To investigate the biological and pathological functions of CCDC134 during embryonic development.
• To generate a conditional knockout mouse model for temporal and spatial control of Ccdc134 gene ablation.

Main Methods:

• Generation of a Ccdc134fl/fl conditional knockout mouse strain.
• Crossing Ccdc134fl/fl mice with Cre-driver lines (human β-actin-Cre or zona pellucida 3-Cre) to achieve gene ablation.
• Analysis of embryonic lethality, developmental abnormalities, and cellular defects in Ccdc134-/- embryos.

Main Results:

• Ccdc134-/- embryos exhibited embryonic lethality between E12.5 and birth.
• Absence of CCDC134 led to severe hemorrhages, abnormal organ development (liver, heart), and placental issues.
• Reduced cell proliferation and vascular endothelial cell defects were observed in E13.5 fetal tissues.
• CCDC134 demonstrated dynamic and specific expression patterns during embryonic development.

Conclusions:

• CCDC134 plays a critical and essential role in mouse embryonic development.
• Loss of CCDC134 results in severe developmental defects, leading to embryonic lethality.
• Further research is warranted to elucidate the precise mechanisms by which CCDC134 regulates embryonic development.
