Precision Therapeutic Strategy for CAD: Targeting PSRC1 & Tryptophan Metabolism
Genome-wide association studies have implicated proline/serine-rich coiled-coil 1 (PSRC1) in coronary artery disease (CAD) pathogenesis. Our previous studies demonstrated that Psrc1 deficiency accelerates atherosclerosis via gut microbial dysbiosis, characterized by a substantial depletion of Akkermansia muciniphila. Recent studies implicate microbiome-dependent tryptophan metabolism as a novel checkpoint in atherosclerosis, with specific microbial taxa regulating metabolite-driven immune responses.

PSRC1's Role in Ahr Regulation
PSRC1 upregulates Ahr expression by attenuating ubiquitination-mediated degradation in macrophages. The study found that Psrc1 stabilizes Ahr protein via Uchl3-mediated deubiquitylation. This direct regulatory mechanism highlights PSRC1's crucial role beyond its indirect effects through tryptophan metabolism, offering a new target for modulating Ahr activity in atherosclerosis.
Targeted Interventions for Atherosclerosis
The research demonstrates that therapeutic restoration of a live A. muciniphila-IAA axis through oral supplementation reversed atherosclerosis in Psrc1 knockout mice. Notably, oral Indoleacetic Acid (IAA) supplementation alone substantially ameliorated atherosclerosis by suppressing plaque macrophage apoptosis. These findings position microbiome-targeted Ahr activation as a precision therapeutic strategy for patients with CAD with PSRC1 loss-of-function variants.
Akkermansia muciniphila and Tryptophan Metabolism
PSRC1 deficiency leads to a substantial depletion of Akkermansia muciniphila and alters tryptophan metabolic enzyme expression. This results in diminished levels of Trp metabolites, including Indoleacetic Acid (IAA), which is critical for Ahr signaling. A. muciniphila acts as a key modulator, metabolizing tryptophan to produce IAA and directly influencing the host's immune responses and atherosclerosis progression.
PSRC1
Critical Regulator of Atherosclerosis
PSRC1 deficiency significantly accelerates atherosclerosis, underscoring its pivotal role in cardiovascular health. This research establishes PSRC1 as a central player in mediating atheroprotective effects through distinct molecular and microbial pathways.

Precision Therapy for CAD with PSRC1 Variants
This study nominates microbiome-targeted Ahr activation as a precision therapeutic strategy for patients with CAD with PSRC1 loss-of-function variants. Oral supplementation of live A. muciniphila or direct Indoleacetic Acid (IAA) reversed atherosclerosis and suppressed plaque macrophage apoptosis in Psrc1 knockout mice. This approach provides a personalized intervention targeting the critical PSRC1-A. muciniphila-IAA-Ahr axis, offering a novel pathway for managing cardiovascular disease.
