Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nU2SURP, a U2 snRNP-associated SURP motif‐containing protein and member of the serine/arginine–rich protein family, is markedly upregulated in triple‐negative breast cancer (TNBC) tissues and is associated with poor patient prognosis. Enhanced by MYC via an eIF3D‐dependent mechanism, U2SURP accumulates in TNBC cells where it exerts oncogenic functions. In these cells, U2SURP promotes tumorigenesis and metastasis by modulating pre–mRNA splicing—specifically, it facilitates the removal of intron 3 from the pre–mRNA of spermidine/spermine N¹‐acetyltransferase 1 (SAT1). This splicing event increases the stability and expression of SAT1 mRNA and protein, thereby reinforcing the malignant properties of the TNBC cells. Importantly, re–expression of SAT1 in U2SURP–depleted cells partially rescues the compromised oncogenic phenotype, emphasizing the critical role of the MYC–U2SURP–SAT1 signaling axis in TNBC progression."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Ling Deng, Li Liao, Yin-Ling Zhang, et al.
