WebIn this study, we assessed their transcriptional activity by measuring in vivo the relative amounts of RNA polymerase II that were cross-linked by UV irradiation to the two different histone repeats. The RNA polymerase II density on the long repeat in Schneider line 2 cells was strikingly lower (10-fold) than the density on the short repeat. WebCrosslinks in DNA occur when various exogenous or endogenous agents react with two different positions in the DNA. This can either occur in the same strand (intrastrand …

WebDNA repair pathways can result in the formation of tumor cells. Cancer treatments have been engineered using DNA cross-linking agents to interact with nitrogenous bases of DNA to block DNA replication. These cross-linking agents have the ability to act as single-agent therapies by targeting and destroying specific nucleotides in cancerous cells. WebHere, we present an efficient protocol to extract DNA from formalin-fixed or paraffin-embedded tissues (FFPE). In this protocol, protein-DNA cross-links are reversed using heat and alkali treatment, yielding significantly longer fragments and larger amounts of PCR-amplifiable DNA than standard DNA extraction protocols.
