Essential role of MESP1-RING1A complex in cardiac differentiation.
Title: Essential role of MESP1-RING1A complex in cardiac differentiation.
we demonstrate that upregulation of MESP1, a key tumor-promoting alteration, functions to create tumor dependency on an inbuilt lineage-survival process. MESP1, being the nodal point of this survival process, sustains the tumor dependency by transcriptionally activating key genes involved in tumor cell initiation, proliferation and progression including EMT
Title: Aberrant expression of embryonic mesendoderm factor MESP1 promotes tumorigenesis.
Study demonstrates that while leaving primitive streak markers unaffected, MESP1 expression is required for timely vascular progenitor specification. Thus, MESP1 expression is essential for the molecular features of early CM, EC and VSMC lineage specification.
Title: MESP1 knock-down in human iPSC attenuates early vascular progenitor cell differentiation after completed primitive streak specification.
The present study firstly provided experimental evidence supporting the concept that a MESP1 lossoffunction mutation may contribute to the development of double outlet right ventricle in humans, which presents a significant insight into the molecular pathogenesis of congenital heart disease.
Title: MESP1 loss‑of‑function mutation contributes to double outlet right ventricle.
results suggest that pathologic variants in MESP1 may contribute to the development of congenital heart disease (CHD) and that additional protein partners and downstream targets could likewise contribute to the wide range of causes for CHD
Title: MESP1 Mutations in Patients with Congenital Heart Defects.
The MESP1-NKX2-5 hESC reporter line allows us to identify molecular cues crucial for specification and expansion of human cardiac mesoderm and early progenitors and their differentiation to specific cardiovascular derivatives.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
