Fine-mapping of DNA modifications in the lactase gene region of humans and mice

Project description:Bisulfite padlock probe technique was used to examine DNA modifications at the lactase gene region for human and mouse tissues DNA modifications were investigated in human sperm, blood, jejunal enterocytes and jejunum lacking enterocytes, as well as mouse jejunal enterocytes and jejunum lacking enterocytes. For WGA samples, a genome devoid of DNA modifications was used to verify the efficiency of the bisulfite conversion reactions (the tissue sources were human or mouse intestine).

Genome-wide DNA methylation analysis on testicular embryonal carcinoma

Project description:Genomic DNA from 6 pure EC and 2 normal testis was fragmented and immunoprecipitated with anti-5mC monoclonal antibodies by MeDIP. After IP, DNA was purified and amplified using Whole Genome Amplification. Subsequently, DNA was biotin-labeled and hybridized to Human Tiling Array 2.0R Chips (Affymetrix) according to the manufacturer’s instruction. Raw data (CEL files) were normalized and analyzed by TAS (Affymetrix). Technical replicate of MeDIP-chip procedure was performed. Testicular embryonic carcinoma (EC) is a major subtype of non-seminomatous germ cell tumors (NSGCTs) in males. To identify epigenetic changes during testicular tumorigenesis, we profiled the DNA methylation of 6 ECs. These samples represent different stages (stage I and stage III) and different extent of invasiveness. Non-cancerous testicular tissues were included. A total of 1167 tumor-hypermethylated differential methylated regions (DMRs) were identified across the genome. Among them, 40 genes/ncRNA were found to have hypermethylated promoters. Interestingly, we found several hypermethylated sex-linked genes, including X-linked genes STAG2, SPANXD/E, MIR1184, Y-linked genes RBMY1A1/1B/1D and FAM197Y2P. Expression of RBMY1A was confirmed by immunohistochemistry in normal germ cells, but lost in EC and seminoma. Our genome-wide analysis identified methylation changes in several previously unknown genes for testicular ECs, which might provide insight into the crosstalk between normal germ cell development and carcinogenesis. A total of 8 DNA samples, including 6 EC and 2 normal testicular tissues

Transcriptome profiling of wild type and Pof mutant Drosophila melanogaster females

Project description:In Drosophila, two chromosome-wide compensatory systems have been characterized; the dosage compensation system acting on the male X-chromosome and the chromosome specific regulation of genes located on the heterochromatic 4th chromosome. Dosage compensation in Drosophila is accomplished by hypertranscription of the single male X-chromosome mediated by the MSL-complex. The mechanism for this compensation is suggested to be an MSL-complex mediated enhanced transcriptional elongation while the mechanism for the compensation mediated by Painting of fourth (POF) on the 4th chromosome has remained elusive. Here we show that POF binds to nascent RNA and this binding is associated with an increase in amount of chromosome 4 transcripts. Furthermore, genes located on the 4th chromosome are enriched in binding of the nucleoplasmic nucleporin component NUP98 and this enrichment correlates to increased POF binding. We also show that genes located in heterochromatic regions have a shorter transition time from site of transcription and to the nuclear envelope. Our current work broadens the understanding about how genes in heterochromatic regions can overcome the repressive influence of their hostile environment. Pof mutant vs. wild type, 3 replicates

Galectins expression profile in mice intestine - Galectin 3 interacting partners identification

Project description:In this present project, we aimed to physiologically dissect the contribution of glycolipid- and lectin-driven endocytosis mechanism that operate within the mice intestine. We therefore decided to first characterize the expression profile of galectins in this tissue and then to focus on the specific implication of galectin 3 in that context and identify a potential binding partner, that may use this endocytic process for its internalization.
