List of microRNA (miRNA) expression is dysregulation in ALCL
| Subtype of PTCL | Dysregulate microRNA | Biology significance |
|---|---|---|
| PTCL-NOS | Overexpressed miR-187 [173] |

| ALK − ALCL | miR-155 | expressed more than10-fold higher in ALK − ALCL. [174] |
| ALCL [176] | Upregulation of miR-135b |
(1) miR-135b mediates NPM-ALK–driven oncogenicity, targets GATA3, STAT6, FOXO1 (2) Renders IL-17-producing immunophenotype to anaplastic large-cell lymphoma |
| ALK + ALCL |
miR-16, MiR-29a, miR-96 Downregulation |

| ALCL |
miR-101 was downregulated in all ALCL cell lines, |
(2) miR-101 in the regulation of mTOR pathway [174] |

AITL PTCL-NOS |
BCL6 and a specific set of miRNAs | Mutual regulation between BCL6 and a specific set of miRNAs controls the TFH phenotype in peripheral T-cell lymphoma [181] |
| Peripheral T-cell lymphoma not otherwise specified | Expression levels of miRNA |
(1) Discriminating PTCL NOS from activated CD4 + and CD8 + T-lymphocytes, such as AITL and ALCL (2) miR-132-3p is also an important modulator of the PTCL NOS transcriptome [182] |
| PTCL NOS | 13 miRNAs upregulated and 7 miRNAs downregulated | the potential to be used as biomarkers for the identification of patients with PTCL NOS [183] |
| Angioimmunoblastic T-cell lymphoma. In AITL, |
Upregulated: miR-146a, miR-193b miR-34a downregulated miR-30b |
Both miR146-a and miR-30b contribute to the pathogenesis of AITL [184] |
