Sera-induced transcriptional signatures in human leukemia cell lines

ABSTRACT: Inflammation is common to many disorders and responsible for tissue and organ damage. However, the associated peripheral cytokine milieu is frequently dilute and difficult to measure, necessitating development of more sensitive and informative biomarkers for mechanistic studies, earlier diagnosis, and monitoring therapeutic interventions. Previously, we have shown that sera from type 1 diabetes (T1D) patients induces a unique disease-specific pro-inflammatory transcriptional profile in fresh peripheral blood mononuclear cells (PBMCs) compared to sera of healthy controls. To address the potential variance introduced by heterogeneity in responsiveness of PBMCs from different donors, we evaluated human leukemia cell lines as surrogates for fresh PBMCs. Expression signatures of 7 different cell lines were 1) tested in their power to differentiate sera of T1D patients from healthy controls; and 2) compared to the signature obtained with fresh PBMCs.

Transcription profiling of human leukemia cell lines treated with sera from Type I diabetes patients to investigate sera-induced transcriptional signatures.

Project description:Inflammation is common to many disorders and responsible for tissue and organ damage. However, the associated peripheral cytokine milieu is frequently dilute and difficult to measure, necessitating development of more sensitive and informative biomarkers for mechanistic studies, earlier diagnosis, and monitoring therapeutic interventions.

Expression signatures of 7 different cell lines were 1) tested in their power to differentiate sera of T1D patients from healthy controls; and 2) compared to the signature obtained with fresh PBMCs. For each of the 7 cell lines, we assayed 6 individual samples (three stimulated with recent-onset (RO) T1D sera and three stimulated with healthy control sera). Hence, a total of 42 samples were analyzed in this study.

Transcriptional Signatures as a Disease-Specific and Predictive Inflammatory Biomarker for Type 1 Diabetes [T1D_114]

Project description:The complex milieu of inflammatory mediators associated with many diseases is often too dilute to directly measure in the periphery, necessitating development of more sensitive measurements suitable for mechanistic studies, earlier diagnosis, guiding selection of therapy, and monitoring interventions. Previously, we determined that plasma of recent-onset (RO) Type 1 diabetes (T1D) patients induce a proinflammatory transcriptional signature in fresh peripheral blood mononuclear cells (PBMC) relative to that of unrelated healthy controls (HC). Here, using an optimized cryopreserved PBMC-based protocol, we analyzed larger RO T1D and HC cohorts. In addition, we examined T1D progression by looking at longitudinal, pre-onset and longstanding T1D samples. UPN727 cells were stimulated with autologous plasma (n=7), unrelated healthy control plasma (n=44), recent onset T1D plasma (n=46), longstanding T1D plasma (n=11), or longitudinal series plasma (n=6 time points) from pre/post onset. Gene expression analysis was performed in order to evaluate the transcriptional signature associated with T1D.

Plasma induced signatures reveal an extracellular milieu possessing an immunoregulatory bias in treatment naïve inflammatory bowel disease

Project description:The complex milieu of inflammatory mediators associated with many diseases is often too dilute to directly measure in the periphery, necessitating development of more sensitive measurements suitable for mechanistic studies, earlier diagnosis, guiding selection of therapy, and monitoring interventions. Previously, we determined that plasma of recent-onset (RO) Type 1 diabetes (T1D) patients induce a proinflammatory transcriptional signature in fresh peripheral blood mononuclear cells (PBMC) relative to that of unrelated healthy controls (HC). Here, using an optimized cryopreserved PBMC-based protocol, we apply this approach to inflammatory bowel disease by examining groups of Crohn's disease (CD) and ulcerative colitus (UC) patients. The induced plasma induced signatures are compared to those of Type 1 diabetes patients (RO T1D) as well as unrelated healthy controls (uHC).

UPN727 cells were stimulated with either plasma from unrelated healthy controls (n=18) or plasma from patients with bacterial pneumonia (n=10). Gene expression analysis was perfromed in order to evaluate the transcriptional signature associated with bacterial pneumonia.
