BigField GEG Tech's insight:
A new study shows that CRISPR–Cas9 screens are feasible in vivo and can be used to identify tumour suppressor genes.

In mammals, parthenogenesis is limited because of problems arising from genomic imprinting. Here, the scientists report live mammalian offspring derived from single unfertilized eggs. This was achieved by the targeted DNA methylation rewriting of seven imprinting control regions. By designing guide RNAs with protospacer adjacent motif (PAM) sequences matching one allele but not the other, dCas9-Dnmt3a or dCpf1-Tet1 enables targeted DNA methylation editing in an allele-specific manner. The success of parthenogenesis in mammals opens many opportunities in agriculture, research, and medicine.
