TRIM71R595H/R595H mutations and TRIM71-KO in mESC lead to similar transcriptomic changes, which indicate a poised state toward neural differentiation

Mutations in TRIM71's RNA-binding domain leads to congenital hydrocephalus in human patients and a TRIM71 mutant mouse model (Trim71R595H/+). Additionally, homozygous Trim71R595H/R595H mice phenocopy the neural tube defects and premature neural differentiation observed in TRIM71-KO mice. As RNA-Seq analyses revealed that TRIM71-KO mESC are poised for neural differentiation, we aimed to also examine the transcriptomes of TRIM71R595H/R595H and TRIM71R595H/+ mESC. Both TRIM71-KO and TRIM71R595H/R595H mutations in mESC result in transcriptomic changes with similar patterns, when compared to control mESC. Similar to TRIM71-KO, the transcriptome of Trim71R595H/R595H mESC indicates a poised state of mutated mESC towards neural differentiation. Overall design: bulk-mRNA sequencing of Trim71-cond, -KO, and WT, Trim71-R595H/R595H, -R595H/+ mESC
