A common challenge in avian cell biology is the generation of differentiated cell-lines, especially in the keratinocyte lineage. Only a few avian cell-lines are available and very few of them show an interesting differentiation profile. During the last decade, mammalian

Three-prime repair exonuclease 1 (TREX1) is an anti-viral enzyme that cleaves nucleic acids in the cytosol, preventing accumulation and a subsequent type I interferon-associated inflammatory response. Autoimmune diseases, including Aicardi-Goutières syndrome (AGS) and systemic lupus erythematosus, can arise when TREX1

Cisplatin is a chemotherapy drug that kills cancer cells by damaging their DNA. In human cells, this damage is repaired primarily by nucleotide excision repair. While cisplatin is generally effective, many cancers exhibit initial or acquired resistance to it. Here

Protein-DNA interactions are critical to maintain genome stability, DNA replication, chromosome -segregation and to regulate gene expression. Chromatin immunoprecipitation (ChIP) is a powerful technique to study these interactions within living neurons and nervous tissue. In particular, ChIP analysis of chromatin

Dental pulp stem cells (DPSCs) from adult teeth show the expression of a very complete repertoire of stem pluripotency core factors and a high plasticity for cell reprogramming. Canonical Wnt and Notch signaling pathways regulate stemness and the expression of

Disruption of RNA splicing causes genome instability, which could contribute to cancer etiology. Furthermore, RNA splicing is an emerging anti-cancer target. Thus, we have evaluated the influence of the spliceosome factor PRPF8 and the splicing inhibitor Pladienolide B (PlaB) on

Ribosome biogenesis in eukaryotes is supported by hundreds of ribosomal RNA (rRNA) gene copies that are encoded in the ribosomal DNA (rDNA). The multiple copies of rRNA genes are thought to have low sequence diversity within one species. Here, we

Malaria-causing parasites achieve rapid proliferation in human blood through multiple rounds of asynchronous nuclear division followed by daughter cell formation. Nuclear divisions critically depend on the centriolar plaque, which organizes intranuclear spindle microtubules. The centriolar plaque consists of an extranuclear

Benzo[a]pyrene (BaP), a polycyclic aromatic hydrocarbon, is the major cause of lung cancer. BaP forms covalent DNA adducts after metabolic activation and induces mutations. We have developed a method for capturing oligonucleotides carrying bulky base adducts, including UV-induced cyclobutane pyrimidine

Repeat-mediated deletions (RMDs) often involve repetitive elements (e.g., short interspersed elements) with sequence divergence that is separated by several kilobase pairs (kbps). We have examined RMDs induced by DNA double-strand breaks (DSBs) under varying conditions of repeat sequence divergence (identical versus
