RedChIP identifies noncoding RNAs associated with genomic sites occupied by Polycomb and CTCF proteins

Abstract Nuclear noncoding RNAs (ncRNAs) are key regulators of gene expression and chromatin organization. The progress in studying nuclear ncRNAs depends on the ability to identify the genome-wide spectrum of contacts of ncRNAs with chromatin. To address this question, a panel of RNA–DNA proximity ligation techniques has been developed. However,…

The Point of Base Editors: Correcting Point Mutations

Some genome editing systems are highly conspicuous. They introduce double-strand breaks to DNA that attract the attention of cellular mechanisms such as nonhomologous end joining and homology-directed repair. If a genome editing system is so brash as to attempt a sizable insertion of new DNA, homology-directed repair must ensure that…

Dissecting Cancer with Single-cell DNA Sequencing & Multi-omics | Learning Center

CANCER & SINGLE-CELL ANALYSIS The heterogeneity and dynamism of cancer present formidable challenges to understanding and treating the disease. As discussed in the last section, tumor evolution often leads to considerable genetic variation across clones. But the complexity of tumors does not stop at the level of DNA. Intratumoral phenotypic…
