View SamplesBecause of the extensive data in mice supporting the concept that ST2+ Tregs might have desirable therapeutic properties, including tissue repair function, high suppressive capacity, and enhanced stability, we engineered human blood Tregs to constitutively express ST2 (IL-33R). Here we used RNA sequencing to explore the effects of short-term culture with IL-33 on human ST2-transduced Tregs. Overall design: Human naive Tregs flow-sorted from 4 independent donors were lentivirally transduced with ST2, expanded for 13 days, then stimulated with IL-2 and TCR (16 h) or IL-2, TCR, and IL-33 (16 h).

View SamplesZNF521 is a multiple zinc finger transcription factor previously identified because abundantly and selectively expressed in normal CD34+ hematopoietic stem and progenitor cells. From microarray datasets, aberrant expression of ZNF521 has been reported in both pediatric and adult acute myeloid leukemia (AML) patients with MLL gene rearrangements. However, a proper validation of microarray data is lacking, likewise ZNF521 contribution in MLL-rearranged AML is still uncertain. In this study, we show that ZNF521 is significantly upregulated in MLL translocated AML patients from a large pediatric cohort, regardless of the type of MLL translocations such as MLL-AF9, MLL-ENL, MLL-AF10 and MLL-AF6 fusion genes. Our in vitro functional studies demonstrate that ZNF521 play a critical role in the maintenance of the undifferentiated state of MLL-rearranged cells. Furthermore, analysis of the ZNF521 gene promoter region shows that ZNF521 is a direct downstream target of both MLL-AF9 and MLL-ENL fusion proteins. Gene expression profiling of MLL-AF9-rearranged THP-1 cells after depletion of ZNF521 reveals correlation with several expression signatures including stem cell-like and MLL fusion dependent programs. These data suggest that MLL fusion proteins activate ZNF521 expression to maintain the undifferentiated state and contribute to leukemogenesis.

View SamplesTotal RNA from trichomes of fifth and sixth rosette leaves of three-week-old wild-type and gtl1-1 mutants (Figure 3B) were extracted. We found a total number of 1,759 genes, corresponding to 1,694 probes on the ATH1 chip, that show differential expression of at least 1.3-fold. Out of these 1,694 genes, 47.2% are positively regulated and 52.8% are negatively regulated by GTL1.

View SamplesKRAS mutations are the ost abundand driver mutations found in lung adenocarcinoma patients. Unfortunately, there are no clinical approved inhibitors available, to directly target mutant forms of KRAS. The aim of the study was to unravel the impact of upstream Egfr activation in signaling of mutated K-ras. We found that upregulation of G12D mutant Kras induced genes was significantly impaired when Egfr was knocked out. Our data suggests that signaling of mutant Kras depends on upstream activation. This finding may be exploited therapeutically by targeting EGFR in KRAS mutant patients. Overall design: We isolated mouse alveolar type II cells and induced the Kras G12D mutation, with and without concomitant Egfr knockout, in vitro. Cells lysates were analyzed 5 days following transgene induction.

View SamplesHow plants determine the final size of growing cells is an important, yet unanswered question. Root hairs provide an excellent model system to study this question since their final cell size is remarkably constant under given environmental conditions. In this study we demonstrate that a trihelix transcription factor GT-2-LIKE1 (GTL1) and its homolog DF1 repress root hair growth in Arabidopsis. Our transcriptional data, combined with genome-wide chromatin binding data, show that GTL1 and DF1 directly bind the RSL4 promoter and regulate its expression to repress root hair growth. Our data further show that GTL1 and RSL4 regulate each other as well as a set of common downstream genes, many of which have previously been implicated in root hair growth. This study therefore uncovers a core regulatory module that fine-tunes the extent of root hair growth by orchestrated actions of opposing transcription factors.
