Myocardial infarction (MI) remains the leading cause of death worldwide. Cardiac fibroblasts (CFs) are abundant in the heart and are responsible for cardiac repair post‐MI. NF‐κB‐repressing factor (NKRF) plays a significant role in the transcriptional inhibition of various specific genes. However, the NKRF action mechanism in CFs remains unclear in cardiac repair post‐MI. This study investigates the NKRF mechanism in cardiac remodeling and dysfunction post‐MI by establishing a CF‐specific NKRF‐knockout (NKRF‐CKO) mouse model. NKRF expression is downregulated in CFs in response to pathological cardiac remodeling in vivo and TNF‐α in vitro. NKRF‐CKO mice demonstrate worse cardiac function and survival and increased infarct size, heart weight, and MMP2 and MMP9 expression post‐MI compared with littermates. NKRF inhibits CF migration and invasion in vitro by downregulating MMP2 and MMP9 expression. Mechanistically, NKRF inhibits human antigen R (HuR) transcription by binding to the classical negative regulatory element within the HuR promoter via an NF‐κB‐dependent mechanism. This decreases HuR‐targeted M mp 2 and M mp 9 mRNA stability. This study suggests that NKRF is a therapeutic target for pathological cardiac remodeling. Myocardial infarction (MI) is a leading global cause of mortality. Cardiac fibroblasts (CFs) are crucial for post‐MI cardiac repair. This study investigates the role of NF‐κB‐repressing factor (NKRF) in CFs during post‐MI remodeling, revealing its regulation of MMP2 and MMP9 expression and influence on CF migration and invasion. NKRF emerges as a potential therapeutic target to improve cardiac function post‐MI.
