Biological function: circBCL11B supports leukemic cell proliferation and survival under stress conditions; knockdown reduced proliferation and increased cell death/apoptosis in AML cell lines.
Molecular mechanism: circBCL11B is formed by circularization of exon 2 of BCL11B and is associated with a T-cell-like gene expression signature in AML; its precise molecular mechanism was not defined in this study.
Biological pathway or process:

proliferation (promotes); apoptosis (inhibits); other pathway/process (other)

Detected method:
Q
S
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNA-seq; Clinical Sample Validation; Bioinformatics Analysis; Transfection; Annexin V/PI Flow Cytometry; Western Blot

Clinical significance:

circBCL11B was exclusively expressed in AML patients compared with healthy HSPCs and was associated with a T-cell-like gene expression signature; the association was validated in an independent AML cohort.

Description:

circBCL11B is a BCL11B exon 2-derived circular RNA that was detected exclusively in AML samples and not in healthy HSPCs. Its high expression was associated with a T-cell-like gene expression signature, and shRNA-mediated knockdown impaired AML cell proliferation and increased cell death/apoptosis under serum-deprivation stress. The study supports circBCL11B as a functionally relevant AML-associated circRNA candidate, although its detailed molecular mechanism remains unresolved.
