Project description:We analysed the effect of the deficiency Df(2R)ED3921 and Df(2R)ED50000 on gene expression in embryos (stage 0-11), and wing imaginal discs and brains from 3rd instar larvae. Df(2R)ED3921 and Df(2R)ED50000 were described in Ragab et al. (2005) Genetics 172:1069-1078 2005.

Project description:We analysed the effect of the deficiency Df(2R)ED3921 and Df(2R)ED50000 on gene expression in embryos (stage 0-11), and wing imaginal discs and brains from 3rd instar larvae. Df(2R)ED3921 and Df(2R)ED50000 were described in Ragab et al. (2005) Genetics 172:1069-1078 2005. RNA from Df(2R)ED3921 and Df(2R)ED50000 embryos was compared to a pool of RNA extracted from wild-type embryos at the same stage. For each genotype, 4 independent biological replicates were performed (2 of these dyes swapped with respect to the other two). The same experimental protocol and genotypes were used for the analysis in dissected wing imaginal discs and brains from 3rd instar larvae.

Project description:The aim of this study is to understand the mechanisms of TDP-43 neurotoxicity. Here, we perform a RNA-Seq analysis in TDP-43 gain-of-fucntion (GOF) , TDP-43 loss-of-function and wild-type late pupae heads (73-90 hours APF) and perform TDP-43 GOF vs wild type and TDP-43 LOF vs wild-type differential expression analysis to show that both mechanisms presents defects in ecdysone receptor (ECR)-dependeint transcriptional program switching, and strongly deregulate expression from the neuronal microtubule associated protien Map205. RNA-seq was performed in two wild-type D.melanogaster biological replicates (Canton S, w1118 ), four biological replicates for TDP-43 (LOF) with two distinct genotypes (dTDP-43Δ142/Df(2R)106,dTDP-43Δ23/Δ142 ) and two TDP-43 GOF biological replicates (act5c>dTDP-43 ).

Project description:Many protein complexes are involved in gene regulation during Drosophila spermatogenesis. tplus3a and tplus3b code for Plus3 domain proteins and are enriched in spermatocytes. Male flies ∆tplus3a/b carrying deletions of both genes in trans to deficiency Df(2L)BSC151 show severely reduced fertility. tbrd-1 is known to regulate hundreds of genes during spermatogenesis in cooperation with tTAFs. To gain more insight into the regulatory mechanisms during spermatogenesis we used RNA from testes of ∆tplus3a/b/Df(2L)BSC151 and tbrd-11 mutant flies for RNAseq in comparison to w1118 wild-typic control. RNA was isolated with Trizol from 200 Testes dissected from w1118, homozygous tbrd-11 mutants or ∆tplus3a/b/Df(2L)BSC151. After DNAse I digestion RNA was purified and RNAseq was performed in three replicates. Genotype Description: w1118: wild-typic control tbrd-11: homozygous tbrd-11 mutants (knock-out through P{EPgy2}tbrd-11, as described in Leser et al., 2012) ∆tplus3a/b/Df(2L)BSC151: CRISPR/Cas9 deletion mutants, representing knock-out of both tplus3 and tplus3b. Male flies y1cho2v1;∆tplus3a/b/CyO were crossed with virgin females w1118;Df(2L)BSC151/CyO. Male offspring with w1118;∆tplus3a/b/Df(2L)BSC151 were used for RNAseq.

Project description:Aneuploidy, i.e., variation in the number of individual chromosomes (chromosomal aneuploidy) or chromosome segment (segmental aneuploidy) is associated with developmental abnormalities and reduced fitness in all species examined, is the leading cause of miscarriages and mental retardations and a hallmark of cancer. Despite their documented importance in disease the effects of aneuploidies on the transcriptome remains largely unknown. Here we have examined the expression output in seven deficiency heterozygotes as single deficiencies and in all pairwise combinations. The results show that genes in one copy are buffered, i.e., are expressed above the expected 50% expression level compared to wild type and the buffering is general and not influenced by additional haploid regions. Long genes are significantly better buffered than short genes and our analysis suggests that gene length is the primary determinant for the degree of buffering. For short genes the degree of buffering depends on expression level and expression pattern. Furthermore, the results show that in deficiency heterozygotes the expression of genes involved in proteolysis is enhanced and negatively correlates with the degree of buffering. Our results suggest that proteolysis is a general response induced by aneuploidy. We prepared total RNA from flies heterozygous for seven different deletions, Df(3R)ED10953, Df(2L)ED4559, Df(2R)ED1770, Df(2R)ED1612, Df(2L)ED3, Df(3R)ED5071 or Df(3R)ED7665 in two or three single biological replicates or in pairwise combinations, as well as from six biological replicates of wild type control flies.
