View SamplesCutaneous T-cell lymphoma (CTCL) develops from clonally expanded CD4+ T cells in a background of chronic inflammation. Dendritic cells (DCs) are potent T-cell stimulators; yet despite DCs' extensive presence in skin, cutaneous T cells in CTCL do not respond with effective anti-tumor immunity. We evaluated primary T-cell and DC émigrés from epidermal and dermal explant cultures of skin biopsies from CTCL patients (n = 37) and healthy donors (n = 5). Compared with healthy skin, CD4+ CTCL populations contained more T cells expressing PD-1, CTLA-4, and LAG-3; and CD8+ CTCL populations comprised more T cells expressing CTLA-4 and LAG-3. CTCL populations also contained more T cells expressing the inducible T-cell costimulator (ICOS), a marker of T-cell activation. DC émigrés from healthy or CTCL skin biopsies expressed PD-L1, indicating that maturation during migration resulted in PD-L1 expression irrespective of disease. Most T cells did not express PD-L1. Using skin samples from 49 additional CTCL patients for an unsupervised analysis of genome-wide mRNA expression profiles corroborated that advanced T3/T4 stage samples expressed higher levels of checkpoint inhibition genes compared with T1/T2 stage patients or healthy controls. Exhaustion of activated T cells is therefore a hallmark of both CD4+ and CD8+ T cells directly isolated from the lesional skin of patients with CTCL, with a continuum of increasing expression in more advanced stages of disease. These results justify identification of antigens driving T-cell exhaustion and the evaluation of immune checkpoint inhibition to reverse T-cell exhaustion earlier in the treatment of CTCL. Overall design: RNA-seq correlated with tumor stages

View SamplesThe cure rate for childhood ALL has improved considerably in part because therapy is routinely tailored to the predicted risk of relapse. Various clinical and laboratory variables are used in current risk-stratification schemes, but many children who fail therapy lack adverse prognostic factors at initial diagnosis. Using gene expression analysis, we have identified genes and pathways in a NCI high-risk childhood B-precursor ALL cohort at diagnosis that may play a role in early blast regression as correlated with the Day 7 marrow status. We have also identified a 47-probeset signature (representing 41 unique genes) that was predictive of long term outcome in our dataset as well as three large independent datasets of childhood ALL treated on different protocols.

View SamplesEstablishment of a transcriptomic profile of human cells treated with genistein with particular emphasis on signature of genes coding for enzymes involved in glycosaminoglycan synthesis stands for the present study. The hypothesis tested was that indomethacin and nimesulide influence expression of some genes among which are those coding for enzymes required for synthesis of different GAGs being pathologically accumulated in mucopolysaccharidoses. Results provide important information concerning the extent of action of indomethacin and nimesulide at the molecular level in terms of modulation of gene expression by these substances.

View SamplesEstablishment of a transcriptomic profile of human cells treated with genistein with particular emphasis on the assessment of the role of this isoflavone in regulation of expression of psoriasis-related genes stands for the present study. The hypothesis tested was that genistein modulates activity of psoriasis-related genes, by reducing the expression efficiency of genes revealing enhanced activity in psoriatic cells, and by stimulating the expression efficiency of genes revealing decreased activity in psoriatic cells. Results provide important information concerning the extent of action of genistein at the molecular level in terms of modulation of gene expression by this substance.
