Transcription profiling of primary fibroblasts from a family with autosomal recessive Hutchinson-Gilford Progeria Syndrome

ABSTRACT: Hutchinson-Gilford progeria syndrome (HGPS) is a genetic disorder displaying features reminiscent of premature senescence caused by germline mutations in the LMNA gene encoding lamin A and C, essential components of the nuclear lamina. By studying a family with homozygous LMNA mutation (K542N), we showed that HGPS can also be caused by mutations affecting both isoforms, lamin A and C (J Med Genet 2004;41:609M-^V614). With the aim to elucidate the molecular mechanisms underlying the pathogenesis of lamin A/C-related (hereditary) HGPS, we investigated primary cultured skin fibroblasts from affected homozygous K542N carriers (n=3), healthy heterozygotes (n=3), and controls (n=3) for differences in global gene expression using GeneChip Human Genome U133 Plus 2.0 arrays (Affymetrix UK Ltd.).

Project description:The Wilms tumor-suppressor gene WT1, a key player in renal development, also has a crucial role in maintenance of the glomerulus in the mature kidney. However, molecular pathways orchestrated by WT1 in podocytes, where it is highly expressed, remain unknown. Their defects are thought to modify the cross-talk between podocytes and other glomerular cells and ultimately lead to glomerular sclerosis, as observed in diffuse mesangial sclerosis (DMS) a nephropathy associated with WT1 mutations. To identify podocyte WT1 targets, we generated a novel DMS mouse line, performed gene expression profiling in isolated glomeruli, and identified excellent candidates that may modify podocyte differentiation and growth factor signalling in glomeruli. Scel, encoding sciellin, a protein of the cornified envelope in the skin, and sulf1, encoding a 6-O endosulfatase, are shown to be expressed in wild type podocytes and to be strongly down-regulated in mutants. Co-expression of Wt1, Scel and Sulf1 was also found in a mesonephric cell line, and siRNA-mediated knockdown of WT1 decreased Scel and Sulf1 mRNAs and proteins. By ChIP we show that Scel and Sulf1 are direct WT1 targets. Cyp26a1, encoding an enzyme involved in the degradation of retinoic acid, is shown to be up-regulated in mutant podocytes. Cyp26a1 may play a role in the development of glomerular lesions but does not seem to be regulated by WT1. These results provide novel clues in our understanding of normal glomerular function and early events involved in glomerulosclerosis. Experiment Overall Design: Isolation of glomeruli from mutant (FVB-N4 Wt1+/R394W) and wild-type (FVB-N4 Wt1+/+) was performed after cardiac Dynabead perfusion. GeneChip analysis of glomeruli from 5 Wt1+/R394W mice and 5 Wt1+/+ littermates (N4-FVB) were performed independently. Animals were unweaned 27-day-old males. The Wt1+/R394W mice used were showing little albuminuria (<3 ug/ul on Coomassie blue stained SDS-PAGE gel) and no evidence of mesangial lesions by light microscopy.

Project description:The anaerobic metabolism of the opportunistic pathogen Pseudomonas aeruginosa is important for growth and survival during persistent infections. The two Fnr-type transcription factors Anr and Dnr regulate different parts of the underlying network. Both are proposed to bind to a non-distinguishable DNA sequence named Anr box. The aim of this study was the identification of genes induced under anaerobic conditions in the P. aeruginosa wild type and identification of genes under control of the Anr or Dnr regulators. We performed three comparisons to identify genes induced under anaerobic denitrifying conditions in the P. aeruginosa wild type strain and genes which are under control of the Anr or Dnr regulators under these anaerobic conditions. Since the anr and dnr mutant strains do not grow under anaerobic denitrifying conditions, we applied anaerobic shift experiments. Pseudomonas aeruginosa was grown in a modified AB minimal medium, containing 25 ÂµM FeSO4, 20 mM glucose and 50 mM NaNO3. The 200 ml aerobic cultures were grown in 1 l Erlenmeyer flasks at 37 oC and 300 rpm. The aerobic culture was grown to an OD578 of 0.3. For the aerobic culture, cells were harvested at this point. For the anaerobic shift experiments 130 ml of the respective aerobic culture were transferred to a 135 ml sealed serum flask. Control experiments verified that oxygen tension decreased within 3 - 5 min below the detection limit of an oxygen electrode. The cells were harvested after incubation for additional 2h under anaerobic conditions. Within these 2h incubation period no growth of the wild type, the anr mutant or the dnr mutant strain was observed. First comparison: Identification of genes induced or repressed under anaerobic conditions in the P. aeruginosa wild type PAO1. Here we compared the transcriptome profile of P. aeruginosa PAO1 grown under aerobic conditions up to an OD578 of 0.3 with the transcriptome profile of the PAO1 strain, which was first grown under aerobic conditions up to an OD578 of 0.3 and than shifted to anaerobic conditions by transfer to a sealed serum flask and further incubated for two hours under anaerobic conditions. Second comparison: Identification of genes regulated differently in the anr mutant strain PAO6261. Here we compared the transcriptome profile of the P. aeruginosa wild type PAO1 with the transcriptome profile of the P. aeruginosa anr mutant strain PAO6261. Both strains were harvested after 2h incubation under anaerobic conditions. Third comparison: Identification of genes regulated differently in the dnr mutant strain RM536. Here we compared the transcriptome profile of the P. aeruginosa wild type PAO1 with the transcriptome profile of the P. aeruginosa dnr mutant strain RM536. Both strains were harvested after 2h incubation under anaerobic conditions.
