Description
In addition to helper and regulatory potential, CD4+T cells also acquire cytotoxic activity marked by granzyme B (GzmB) expression and the ability to promote rejection of established tumors. Here we examined the molecular and cellular mechanisms underpinning the differentiation of cytotoxic CD4+T cells following immunotherapy. CD4 transfer into lymphodepleted animals or regulatory T cell (Treg)depletion promoted GzmB expression by tumor-infiltrating CD4+which was prevented by IL-2 neutralization. Transcriptional analysis revealed a polyfunctional helper and cytotoxic phenotype characterized bythe expression of the transcription factors T-bet and Blimp-1. Whilst T-bet ablation restrictedIFN-gproduction, lossof Blimp-1preventedGzmB expressionin response to IL-2, suggesting these are two independent programs required forpolyfunctionality of tumor-reactive CD4+T cells. The data underscores the role of Treg, IL-2 and Blimp-1 controlling the differentiation of cytotoxic T cells and offers a pathway to enhancement of anti-tumor activity through their manipulation.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The Human T-cell Leukemia Virus (HTLV)-type-I non-structural protein p30 plays an important role in virus transmission and gene regulation. p30 has been documented to inhibit the export of certain viral mRNA transcripts from the nucleus to the cytoplasm. This nuclear retainment of RNA molecules essentially results in gene silencing, where protein products are not produced.
Publication Title
Genome wide analysis of human genes transcriptionally and post-transcriptionally regulated by the HTLV-I protein p30.

Description
To determine cardiac transcription profile in cyanotic Tetralogy of Fallot patients subjected to conrolled reoxygenation cardiopulmonary bypass, we collected myocardial samples at the end of the ischemic time. The transcriptional profile of the mRNA in these samples was measured with gene array technology

Description
To investigate changes in cardiac transcription profiles caused by off-pump cardiac surgery, we collected myocardial samples, prior and after grafting, from patients undergoing off-pump coronary revascularization surgery. The transcriptional profile of the mRNA in these samples was measured with gene array technology. Changes in transcriptional profiles can be correlated with the stress response of heart to off-pump surgery.

Description
To investigate changes in cardiac transcription profiles caused by on-pump cardiac surgery, we collected myocardial samples, prior and after grafting, from patients undergoing on-pump coronary artery bypass grafting with cardiopulmonary bypass and cardiac arrest. The transcriptional profile of the mRNA in these samples was measured with gene array technology. Changes in transcriptional profiles can be correlated with the stress response of heart to surgery, cardiopulmonary bypass and cardiac arrest.
