Molecular signatures in peripheral T-cell lymphoma (PTCL). Homo sapiens

Molecular signatures to improve diagnosis in PTCL and prognostication in angioimmunoblastic T-cell lymphoma (AITL). Gene expression profiling of PTCL patient samples was performed to investigate whether molecular signatures can be used to identify distinct entities of PTCL. Overall design: Gene expression profiling was performed on PTCL and natural-killer cell lymphoma (NKCL) to define molecular classifiers for the more common entities of PTCL, to identify unique entities within PTCL-U, to elucidate unique tumor and microenvironmental interactions and oncogenic pathways in AITL, and to construct a molecular prognosticator for AITL.
