Description
Angioimmunoblastic T cell lymphoma (AITL) represents a distinctive form of peripheral T cell lymphoma with a dismissal prognosis. Recent exome sequencing in AITL patients revealed frequent coexistence of somatic mutations in the RHO GTPase (RHOAG17V) and the 5-methylcytosine oxidase TET2. Here we demonstrated that Tet2 loss and RhoAG17V cooperatively caused abnormal CD4+ T cell proliferation and differentiation by perturbing FoxO1 gene expression and its subcellular localization, an abnormality that is also detected in AITL tumor samples. Re-expression of FoxO1 attenuated aberrant immune responses induced by genetic lesions in both Tet2 and RhoA. Our findings suggest that mutational cooperativity between epigenetic factors and GTPases in adult CD4+ T cells may account for immunoinflammatory responses that are commonly associated with AITL. Overall design: Determine the differential expressed genes between WT, Tet2-/-, RhoAG17V, Tet2-/-RhoAG17V mutant CD4+ T cells.

Xenotransplantation holds the promise of providing an unlimited supply of donor organs for terminal patients with organ failure. The gal carbohydrate results in rejection of wild type pig grafts, however, chimerism established by expression of the GalT gene prior to transplantation in GalT knockout mice results in tolerance to Gal+ heart grafts.

Description
The circadian clock generates daily rhythms in mammalian liver processes, such as glucose and lipid homeostasis, xenobiotic metabolism, and regeneration. The mechanisms governing these rhythms are not well understood, particularly the distinct contributions of the cell-autonomous clock and central pacemaker to rhythmic liver physiology. Through microarray expression profiling in MMH-D3 hepatocytes, we identified over 1,000 transcripts that exhibit circadian oscillations, demonstrating that many rhythms can be driven by the cell-autonomous clock and that MMH-D3 is a valid circadian model system. The genes represented by these circadian transcripts displayed both co-phasic and anti-phasic organization within a protein-protein interaction network, suggesting the existence of competition for binding sites or partners by genes of disparate transcriptional phases. Multiple pathways displayed enrichment in MMH-D3 circadian transcripts, including the polyamine synthesis module of the glutathione metabolic pathway. The polyamine synthesis module, which is highly associated with cell proliferation and whose products are required for initiation of liver regeneration, includes enzymes whose transcripts exhibit circadian oscillations, such as ornithine decarboxylase (Odc1) and spermidine synthase (Srm). Metabolic profiling revealed that the enzymatic product of SRM, spermidine, cycles as well. Thus, the cell-autonomous hepatocyte clock can drive a significant amount of transcriptional rhythms and orchestrate physiologically relevant modules such as polyamine synthesis.

Description
In an acute skin wound, newly released serum growth factors in the wound bed drive lateral migration of human keratinocytes (HKs) to re-epithelialize the wound. However, profiling the migration signal-specific genes has long been challenged by pleiotropic effects of a given growth factor, including proliferation, migration and factor-specific responses. To overcome these technical problems, we 1) took advantage of a unique response of HKs to transforming growth factor-beta (TGFbeta) to selectively suppress growth signal-responding genes and identify motility-specific genes and 2) employed dual stimulation of HKs with TGFalpha and insulin to identify the common genes and eliminate factor-specific genes. Under these conditions, DNA microarray analyses were utilized to study the profiles of both TGFalpha-regualted and insulin-regulated immediate early (IE, 30 min), early (E, 60 min) and delayed early (DE, 120 min) genes.
