Project description:Dwivedi2014 - Crohns IL6 Disease model -
Anti-IL6 Antibody
This model is comprised of four models:
[BIOMD0000000534]
Healthy Volunteer model
[BIOMD0000000535]
Crohn's Disease - IL-6 Antibody
[BIOMD0000000536]
Crohn's Disease - sgp130FC
[BIOMD0000000537]
Crohn's Disease - IL-6Ra Antibody
Possible avenues for Interleukin-6 (IL-6) inhibition in
treating Crohn's disease are compared here. Each model refers to
separate ligands. The system simulates differential activity of the
ligands on the signalling of IL-6.
This affects Signal Transducer and Activator of
Transcription 3 (STAT3) activity on the production of
biomarker C-Reactive Protein (CRP) expression.
Figures referring to this Crohn's Disease model are 4a, 4b,
4c and 5a.
This model is described in the article:

interleukin-6-mediated immune regulation in Crohn's disease and
its application in drug discovery and development.

Abstract:
In this study, we have developed a multiscale systems model
of interleukin (IL)-6-mediated immune regulation in Crohn's
disease, by integrating intracellular signaling with
organ-level dynamics of pharmacological markers underlying the
disease. This model was linked to a general pharmacokinetic
model for therapeutic monoclonal antibodies and used to
comparatively study various biotherapeutic strategies targeting
IL-6-mediated signaling in Crohn's disease. Our work
illustrates techniques to develop mechanistic models of disease
biology to study drug-system interaction. Despite a sparse
training data set, predictions of the model were qualitatively
validated by clinical biomarker data from a pilot trial with
tocilizumab. Model-based analysis suggests that strategies
targeting IL-6, IL-6R?, or the IL-6/sIL-6R? complex are less
effective at suppressing pharmacological markers of Crohn's
than dual targeting the IL-6/sIL-6R? complex in addition to
IL-6 or IL-6R?. The potential value of multiscale system
pharmacology modeling in drug discovery and development is also
discussed.CPT: Pharmacometrics & Systems Pharmacology

Project description:Discovery of the genome-wide location of proteins using ChIP-Seq has allowed global mapping of the key transcription factors and chromatin regulators that control gene expression programs in various cells. Many DNA-associated processes are targeted for disease therapy. This study investigates the functions of small molecule therapeutics that target DNA-associated processes involved of CDK9 and BRD4. Genomic DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. ChIP was performed using an antibody against RNAP2, BRD4, CDK9, and CTCF using whole cell extract (WCE) as a background control.
