The aim of this study was to investigate if milk fat globule membrane (MFGM) enclosing the dairy fat influence peripheral blood mononuclear cells (PBMC) gene expression. This study was a 8-week single-blind, randomized, controlled isocaloric trial with two parallel groups including overweight (mean BMI: 28) adult women (n=30). All subjects consumed 40 g dairy fat per day either as cream (MFGM diet) or as butter oil (control diet).

Although this association has long been recognized, underlying mechanisms still require extensive research.

View SamplesBackground: Development of target specific therapeutics greatly benefits from simultaneous identification of biomarkers to determine aspects of bioactivity, drug safety and efficacy or even treatment outcome. This is particularly important when targeting pleiotropic factors such as the TGFbeta system. TGFbeta has become a prime target for cancer therapeutics since inhibition of TGFbeta signaling simultaneously attacks the tumor and its microenvironment. Methods: Here we introduce blood transcriptomics followed by a defined set of validation assays as a promising approach to identify novel biomarkers for monitoring TGFbeta therapy. Findings: Our initial genome-wide analysis of transcription in peripheral blood revealed 12 candidate genes specifically regulated in peripheral blood by the TGFbeta receptor I kinase inhibitor LY2109761. In subsequent in vitro and in vivo molecular and immunological analyses, the combined monitoring of gene regulation of three genes, namely TMEPAI, OCIAD2, and SMAD7 was established as novel biomarkers for anti-TGFbeta based therapies. Interpretation: Overall, the proposed algorithm of biomarker identification is easily adapted towards other drug candidates for which gene regulation can be established in peripheral blood.

View SamplesThe transcription factor Foxp3 is indispensible for the differentiation and function of regulatory T cells (Treg cells). To gain insights into the molecular mechanisms of Foxp3 mediated gene expression we purified Foxp3 complexes and explored their composition. Biochemical and mass-spectrometric analyses revealed that Foxp3 forms multi-protein complexes of 400-800 kDa or larger and identified 361 associated proteins ~30% of which are transcription-related. Foxp3 directly regulates expression of a large proportion of the genes encoding its co-factors. Reciprocally, some transcription factor partners of Foxp3 facilitate its expression. Functional analysis of Foxp3 cooperation with one such partner, Gata3, provided further evidence for a network of transcriptional regulation afforded by Foxp3 and its associates to control distinct aspects of Treg cell biology.
Transcription factor Foxp3 and its protein partners form a complex regulatory network.

View SamplesAnalysis of Foxp3 ablated peripheral regulatory T cells. Regulatory T cells require the expression of the transcription factor Foxp3 for thymic development. It is not known whether continuous expression of Foxp3 is required for the maintained function of mature regulatory T cells in the periphery. Results indicate changes to the regulatory T cell developmental program in the absence of Foxp3.
Maintenance of the Foxp3-dependent developmental program in mature regulatory T cells requires continued expression of Foxp3.

After detecting 1,536 cis-eQTLs (FDR = 10%) and 952 trans-eQTLs, we focused our analysis on Pb-sensitive “trans-eQTL hotspots”.
