CircRNAs derived from the tyrosine phosphatase PTPN22 impact chemosensitivity in ALK-positive T-cell lymphomas

A circular RNA linked to early relapse in aggressive lymphoma works through a specific pathway, suggesting CARM1 inhibition might overcome drug resistance.

RNA-Seq of primary ALK+ ALCL biopsies identified circPTPN22 as upregulated in early relapse, working via the ALK/STAT3 pathway to suppress CARM1 and promote drug tolerance. CARM1 inhibition emerges as a potential strategy to overcome chemoresistance in this aggressive lymphoma subtype.

What the study was

Study design
Translational study — RNA-Seq of primary biopsies + functional in vitro validation
Population
Primary ALK+ ALCL biopsies (relapsed vs non-relapsed); Jurkat/ALK+ lymphoma cell lines
Category
Drug Development
Maturity
Exploratory
Journal
Sci Rep

Why it surfaced

Novel circRNA-CARM1 axis in ALK+ ALCL chemoresistance; CARM1 is a druggable target. Primary biopsy data strengthens translational relevance. In vitro validation limits score.
