SNORA11 and breast cancer: Overexpression of SNORA11 enhanced BC cell proliferation, migration, and invasion, and transcriptomic analysis further revealed that SNORA11 overexpression is associated with enhanced proliferative signaling and suppressed immune-related pathways.<h4>Conclusions</h4>We established a novel snoRNA-based prognostic model with strong predictive power and biological relevance in BC.
