Implication

Randomized trial investigates KRAS G12D's role in disrupting erythroid differentiation in myeloid malignancies, suggesting MRTX1133 as a potential therapy.

Key Points

The aim is to uncover how KRAS G12D mutations affect erythroid differentiation and inflammatory pathways in myeloid malignancies.
Utilized Genotyping of Transcriptomes (GoT) to analyze single cell RNA-seq and mutational status.
Developed a transplantable AdenoCreLox KRASG12D mouse model to mimic human conditions.
Examined patient samples and in vitro behavior of KRASG12D cells distinguished by CD83 expression.
In AML, KRAS G12D mutant cells constituted a unique inflammatory population with CD83 expression.
Treatment with MRTX1133 restored wildtype erythroid differentiation and reduced inflammatory gene activity, including CD83.
Identified a new quiescent CD83+ KRAS G12D progenitor in AML, with potential to hinder disease progression.
