- Affymetrix Human Gene 1.1 ST Array (hugene11st)
Description
Mastermind-like 1 (MAML1) is a transcriptional coregulator that has been associated with early development of many systems such as neuronal, muscular, cardiovascular and urogenital. The present study aimed to explore the genome-wide effects of MAML1 on gene expression and DNA methylation in human embryonic kidney cells. RNA expression was measured using a microarray that screens approximately 36,000 transcripts, and DNA methylation was determined for 450,000 CpG sites. 225 genes were found to be differentially expressed, while 11802 CpG sites were found to be differentially methylated in MAML1-expressing cells. A subset of 211 differentially methylated loci was associated with the expression of 85 genes. Gene ontology analysis revealed that these genes are involved in the regulation of urogenital system development, cell adhesion and embryogenesis.

Description
To characterize the sequence of events associated with RasV12 immortalization of Drosophila embryonic cells, we generated transcriptional time series during cell line establishment, from primary cultures until passage (P) 19. Overall design: We generated three transcriptional time series from three cell lines (R1, R4 and R5) by sampling the cultures at successive stages, early (P2-4), intermediate (P4-11), and late (P16-19), characterized by different passage times. Time points for the R1 time-series were: P2, P3, P4, P5, P7, P8, P10, P11, P16, P17 and P19; for the R4 time-series: P2, P3, P4, P5, P6, P7, P9, P11, P12, P16, P17 and P19; and for the R5 time-series: P2, P3, P4, P6, P7, P8, P16, P17 and P19

Description
Piwi proteins and their associated small RNAs are essential for fertility in animals. This is due, in part, to their roles in guarding germ cell genomes against the activity of mobile genetic elements. piRNA populations direct Piwi proteins to silence transposon targets and as such form a molecular code that discriminates transposons from endogenous genes. Information ultimately carried by piRNAs is encoded within genomic loci, termed piRNA clusters. These give rise to long, single-stranded, primary transcripts that are processed into piRNAs. Despite the biological importance of this pathway, neither the characteristics that define a locus as a source of piRNAs nor the mechanisms that catalyze primary piRNA biogenesis are well understood. We searched an EMS-mutant collection annotated for fertility phenotypes for genes involved in the piRNA pathway. Twenty-seven homozygous-sterile strains showed transposon-silencing defects. One of these, which strongly impacted primary piRNA biogenesis, harbored a causal mutation in CG5508, a member of the Drosophila glycerol-3-phosphate O-acetyltransferase (GPAT) family. These enzymes catalyze the first acylation step on the path to the production of phosphatidic acid (PA). Though this pointed strongly to a function for phospholipid signaling in the piRNA pathway, a mutant form of CG5508, which lacks the GPAT active site, still functions in piRNA biogenesis. We have named this new biogenesis factor Minotaur. Overall design: Examination of transcriptom profile in heterozygous and homozygous CG5508 mutant ovaries
Publication Title
Minotaur is critical for primary piRNA biogenesis.
