Abstract
Follicular lymphoma(FL) is characterized by an indolent and relapsing course. Recently, the clinical outcome of FL has been distinguished by immune microenvironment associated gene signatures. In our study, gene expression profiling (GEP) was performed in 31 nonselected patients with follicular lymphoma (FL), 12 of whom were in relapse and the remaining 19 newly diagnosed. A custom oligonucleotide microarray (Agilent 8 x 15K) was used which contained probes for about 3500 genes, including those that had been previously published as demonstrating significant prognostic value. An unsupervised approach was not able to recognize clinically different FLs. As the previously published prognostically relevant gene signatures could not be properly verified, probably due to microarray platform differences, template matching was therefore used in order to define two gene sets with differential gene expression among our samples. These gene sets shared an overrepresentation of genes with similar biological functions and were termed T CELL and PROLIFERATION profiles. The poor profile was then defined by a high PROLIFERATION score (upper tertile) and or low T CELL score (lower tertile). The poor profile cohort contained a significantly higher proportion of relapsed cases (p 0,05 Fishers exact test). Additionally, a comparison of samples from initial diagnosis and from relapse showed significant differences mainly in the T CELL profile (p=0,036 x (2)). This supports the hypothesis that the number of T cells and their expression pattern play a major role in FL development.
Abstract (in Czech)
Folikulární lymfom (FL) je charakteristický svým indolentním či relabujícím průběhem. V současnosti je možné rozlišit klinický průběh FL pomocí profilování genové exprese v závislosti na mikroprostředí FL. V naší studii jsme stanovili profil genové exprese u 31 pacientů s FL (12 v relapsu, 19 nově diagnostikovaných). K analýze expresního profilu pacientů jsme použili tzv. custom-array (Agilent, formát 8x15K). Unsupervised analýza neodhlalila žádné statisticky významné rozdíly, za použití jiného statistického přístupu (tzv. template matching algorithm) jsme rozlišili dvě sady genů se společnou biologickou funkcí (T-CELL a PROLIFERATION), jejichž exprese se u jednotlivých pacientů lišila v závislosti na klinických projevech onemocnění. Naše práce podporuje hypotézu, že množství T-buněk a jejich expresní profil hraje ve vývoji FL klíčovou roli.
