In a different context, analysis of clear cell renal cell carcinoma (ccRCC) has revealed that dysregulation of lncRNAs plays a vital role in tumor biology. Within a competing endogenous RNA (ceRNA) network, ITPR1‐AS1 is among a signature of nine lncRNAs whose aberrant expression correlates with overall survival and clinical outcome in ccRCC patients."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": " In this setting, ITPR1‐AS1 may function by sequestering microRNAs, thereby modulating the expression of downstream mRNAs that are critical for tumor progression and prognosis. Together, these observations support a role for ITPR1‐AS1 as a context‐dependent regulatory molecule that, by influencing alternative splicing in neuronal cells and acting within a ceRNA network in renal carcinoma, contributes to both cellular differentiation and disease outcome.\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Yuhki Saito, Yuan Yuan, Ilana Zucker-Scharff, et al.
