Description
ALTERED MERISTEM PROGRAM1 (AMP1) is a member of the M28 family of carboxypeptidases with a pivotal role in cell fate maintenance in the embryo and shoot meristem. A defect in AMP1 function results in suspensor to embryo conversion and a hypertrophic shoot meristem forming ectopic stem cell pools. However, so far the role of AMP1 in shoot development could not be assigned to a specific molecular pathway nor is its biochemical function resolved. Double mutants in CYP78A5 and CYP78A7 develop a similar set of cell fate defects. To further assess whether this phenotypic overlap is also depicted in a congruency at the global gene expression level, we analyzed the transcriptomic responses of both genotypes

Description
We identified genes whose expression changes between stage 8 and stage 10. We also identified genes whose expression was altered in stage 10 from temperature senstive ecdysone receptor mutant flies raised at the restrictive temperature. The experiments showed a significant number of genes that are upregulated in stage 10 depend EcR-mediated signaling. Overall design: 3 samples x 3 repeats

- Arabidopsis Gene 1.1 ST Array (aragene11st)
Description
ALTERED MERISTEM PROGRAM1 (AMP1) is a member of the M28 family of carboxypeptidases with a pivotal role in plant development and stress adaptation. Its most prominent mutant defect is a unique hypertrophic shoot phenotype combining a strongly increased organ formation rate with enhanced meristem size and the formation of ectopic meristem poles. However, so far the role of AMP1 in shoot development could not be assigned to a specific molecular pathway nor is its biochemical function resolved. We used a chemical genetic approach to identify the drug hyperphyllin (HP), which specifically mimics the shoot defects of amp1, including plastochron reduction and enlargement and multiplication of the shoot meristem. To further assess whether hyperphyllin acts in an AMP1-dependent manner we compared the transcriptonal responses of hyperphyllin-treated wild-type and amp1 mutant seedlings.

Description
hEPI-NCSC are neural crest derived multipotent somatic stem cells that persist in hair follicle stem cell niche, termed the bulge, and persist into adulthood (Clewes O et al, 2011). The purpose of this project was to generate two gene expression profiles, (1) of ex vivo expanded hEPI-NCSC (XP) and (2) of cells, whihc after expansion were grown in a culture medium (NP1), which was empirically designed to pre-differentiate the multipotent stem cells into neural stemcell like cells.
