C11orf58 encodes a heat-resistant obscure (Hero) protein with chaperone-like activity 1. This protein appears to function in cellular protection under stress conditions, particularly in ischemic settings. In ischemic stroke, C11orf58 expression is significantly downregulated in the acute phase and remains suppressed at day 7, with expression levels inversely correlating with infarct size (R = -0.49 to -0.44, P < 0.05), suggesting neuroprotective properties 1. Bioinformatic analysis indicates C11orf58 involvement in cardiovascular disease pathogenesis through high regulatory potential of its single nucleotide polymorphisms, affecting histone modifications, eQTL effects on CVD-related genes, and transcription factor binding 2. Additionally, gene-based genome-wide association study analysis identified C11orf58 as a novel bone mineral density-associated gene, with differential expression partially validating its role in skeletal metabolism 3. Clinically, C11orf58 represents a potential biomarker for ischemic stroke and a therapeutic target for neuroprotection and stroke recovery 1. Its involvement in multiple disease pathways—cardiovascular disease, stroke, and bone metabolism—suggests C11orf58 functions as a stress-response chaperone with broad physiological significance.
