In ALK-positive anaplastic large cell lymphoma, NPM1::ALK-derived circRNAs f-circA23N2 and f-circA26N3 are linked to shorter survival and systemic dissemination in xenografts.
- Why it matters: Although NPM1::ALK circRNAs have been detected in ALK+ ALCL, their functional role in progression and spread—especially beyond tumor-intrinsic effects—was unclear.
- What they did: Using divergent RT-PCR and long-read Nanopore sequencing, eight NPM1::ALK circRNA variants were found across ALK(+) ALCL models; f-circA23N2 and f-circA26N3 were tested for stability, localization, and effects in SU-DHL-1 and xenografts.
- The result: Overexpression did not change NPM1::ALK levels, proliferation, or cell-cycle, but delayed subcutaneous tumor growth; xenografts showed immune pathway shifts, myeloid remodeling, and that intravenous delivery shortened survival with systemic dissemination.
