Description
The human prostate epithelium is predominantly comprised of two cell-types: basal and luminal. While basal cells exhibit significant progenitor activity in a variety of functional assays, luminal cells are depleted of this activity. Recent studies indicate that approximately 1% of luminal cells exhibit progenitor activity. We have discovered that differential expression of the glycoprotein CD38 can fractionate the luminal population into two subsets: CD38+ and CD38-low. In functional assays, the CD38-low luminal cells exhibit roughly 5-fold increased progenitor activity compared to the remaining CD38+ population. Therefore, we propose that CD38-low luminal cells represent an enriched luminal progenitor population while the CD38+ subset is predominantly comprised of mature non-progenitor luminal cells.

Description
Primary pre-B acute lymphoblastic (ALL) cells do not proliferate long-term ex vivo without the presence of stromal support. We developed and use an ex vivo co-culture model, consisting of mouse leukemic pre-B Bcr/Abl-expressing ALL cells grown with mitotically inactivated mouse embryonic fibroblasts (MEFs). This system provides a generic type of environmentally-mediated protection to the ALL cells, because when the ALL cells are treated with a moderate dose of a therapeutic drug, drug-resistant ALL cells can be recovered after a 1-2 week period of culture. Some of the factors produced by stromal cells that provide protection to ALL cells have been identified. However, it is unclear if the presence of drug-treated ALL cells affects the stromal fibroblasts. The current study was initiated to examine this using expression profiling on the irradiated MEFs.

Description
EML1 and EML3 were previously shown to be histone readers involved in plant-pathogen interactions. To learn more about the developmental function of EML1 and EML3, we generated eml1 eml3 double mutant and showed that it had specific seed developmental phenotypes, including a capability to develop seed without fertilization. Next, we analyzed the mRNA expression of genes in the eml1 eml3 double mutant and compared it to its wild type. Differentially expressed (DE) genes in the mutant were identified and compared with DE of the mutants known to be involved in regulating seed development and in fertilization-independent endosperm development. Our results suggest that some targets are shared between EML histone readers and known regulators of seed development, such as MEA. Auxin response seems to be affected in both types of mutants. However, unlike MEA, EML proteins regulate auxin responsive genes not only in the endosperm, but also in the embryo. This capability makes EML proteins very good candidates for engineering apomictic seeds. Overall design: 3 eml1,eml3 double mutant samples and 3 WT samples

Arabidopsis EMSY-like (EML) histone readers are necessary for post-fertilization seed development, but prevent fertilization-independent seed formation.

Description
Mice lacking the zinc finger transcription factor Specificity protein 3 (Sp3) die prenatally in the C57Bl/6 background. To elucidate the cause of mortality we analyzed the potential role of Sp3 in embryonic heart development. Sp3 null hearts display defective looping at E10.5, and at E14.5 the Sp3 null mutants have developed a range of severe cardiac malformations. In an attempt to position Sp3 in the cardiac developmental hierarchy, we analysed the expression patterns of >15 marker genes in Sp3 null hearts. Expression of Cardiac ankyrin repeat protein (Carp) was downregulated prematurely after E12.5, while expression of the other marker genes was not affected. ChIP analysis revealed that Sp3 is bound to the Carp promoter region in vivo. Microarray analysis indicates that small molecule metabolism and cell-cell interactions are the most significantly affected biological processes in E12.5 Sp3 null myocardium. Since the epicardium showed distension from the myocardium, we studied expression of Wt1, a marker for epicardial cells. Wt1 expression was diminished in epicardium-derived cells in the myocardium of Sp3 null hearts. We conclude that Sp3 is required for normal cardiac development, and suggest that it has a crucial role in myocardial differentiation. (
