Animal germ cells employ small RNA-based mechanisms to recognize and silence DNA that invades their genome. One of these pathways is named the Piwi:piRNA pathway. Biogenesis of piRNAs is poorly understood. In C. elegans, the piRNA (21U-RNA)-binding Argonaute protein PRG-1 is the only known player ac...
To isolate photoreceptor precursors fit for transplantation, we adapted a 3D differentiation protocol that generates neuroretina from mouse ES cells. We used an adeno-associated viral vector (pseudotype2/9)carrying a GFP reporter under the control of a Rhodopsin promoter (AAV2/9.Rhop.GFP)to select r...
DNA topoisomerase I (Top1) is required for transcription as it relaxes positive and negative supercoils by forming transient Top1 cleavage complexes (Top1cc) up- and down-stream of transcription complexes. However, Top1cc can also be trapped by endogenous DNA lesions and by camptothecin (CPT) and it...
Topoisomerase I (Top1) relaxes both positive and negative supercoilings by producing transient Top1 cleavage complexes (Top1cc). Several studies have suggested the implication of Top1 in splicing. Here, we tested the implication of Top1cc in splicing at the global genome level in human carcinoma cel...
162 FFPE samples, representing six different tumour types, were profiled in triplicate across three independent laboratories. OncoScan¬ FFPE assay data was then analysed for reproducibility of genome-wide copy number, loss of heterozygosity and somatic mutations.
