Expression data from responders/nonresponders before/after receiving DLI for relapse of CML s/p BMT

ABSTRACT: Increasing evidence across malignancies suggests that infiltrating T cells at the site of disease are crucial to tumor control. We hypothesized that marrow-infiltrating immune populations play a critical role in response to donor lymphocyte infusion (DLI), an established and potentially curative immune therapy whose precise mechanism remains unknown. We therefore analyzed marrow-infiltrating immune populations in 29 patients (22 responders, 7 nonresponders) with relapsed chronic myelogenous leukemia who received CD4+ DLI in the pre-tyrosine kinase inhibitor era. We used microarrays to detail the global programme of gene expression underlying T cell infiltration into bone marrow of responders and nonresponders to DLI. mRNA expression profiling of marrow-infiltrating CD3+ positively selected T cells of 4 responders compared to 2 non-responders, before and after DLI, was performed on Affymetrix microarrays.

Cellular and Molecular Changes in Psoriasis Lesions Induced by Ustekinumab: Distinct Differences in Responders vs. Non-Responders

Project description:A gene expression profiling sub-study was conducted in which skin biopsy samples (n=192) were collected for RNA extraction and hybridization to microarrays from patients with moderate-to-severe psoriasis who participated in ACCEPT, an IRB-approved Phase 3, multicenter, randomized trial. This analysis identified gene expressions significantly modulated in psoriasis lesions (LS) following ustekinumab or etanercept treatment at week 12 compared to baseline. Molecular expression of mRNA was found to be different in ustekinumab PASI75 responders vs. nonresponders. Differential modulation of selected mRNAs was also observed between ustekinumab and etanercept PASI75 responders.

Transcription profiling of human colorectal cancer biopsies in patients identified as responders/non-responders to preoperative radiotherapy to develop a signature for response to radiotherapy

Project description:Biopsy specimens were collected from rectal cancer before starting preoperative radiotherapy.The expression profiles were determined using Affymetrix Human Genome U95 version 2 arrays.Comparison between the sample groups allow to identify a set of discriminating genes that can be used for characterization of responders and nonresponders to preoperative radiotherapy in rectal cancer. Experiment Overall Design: 35-training and 11-test samples were analyzed

Transcriptomic profiling following de novo hepatitis B vaccination reveals role of granulocytes in non-responders

Project description:As hepatitis B virus is widely spread, WHO recommend vaccination from infancy to reduce acute infection and chronic carriers. However current subunit vaccines are not 100% efficacious and leaves 5-10% persistent non-responders unprotected. To handle large inter-individual variability in immune response after the first Engerix-B vaccination, we employed whole blood early gene expression signatures at day 3 and 7. Immune related pathways are differential expressed in the responders group mostly at day 3 and at day 7 in the non-responders. A notable difference between both groups are significant differential expressed genes at day 0, before vaccination, showing the inter-individual variation. The granulin precursor (GRN) was significant downregulated in responders while upregulated in non-responders. Further absolute granulocytes numbers were significant higher in non-responders. So there is a certain diversity in basic innate immune system.
