A novel genome-wide transcriptional activation screening in Drosophila cells revealed the activation of InR-Akt-mTOR pathway by cholesterol in plasma membrane to confer resistance to Rapamycin.
Both exogenous and endogenous genes can be highly activated in cells by a new dCas9-based activator, CRISPR-assisted trans enhancer, that can be used to activate genes for biomedical applications.

CRISPR genome editing technology can efficiently introduce mutations into lytic and latent HSV genomes to block lytic replication and reactivation of latent herpes simplex virus genome though differential mechanisms.
Cas12a CRISPR arrays are sensitive to the GC content of their spacers, but AT-rich separator sequences successfully remove this disruptive effect and enable enhanced multiplexed gene targeting and activation.

A proteo-genomic CRISPR activation screening workflow to accelerate the identification of novel interactions between the secreted and membrane proteome with the potential to define new biological processes and identify future therapeutic targets.
Kiss1ARH neurons transition from synchronous to burst firing under preovulatory levels of E2, causing a shift from peptidergic to glutamatergic transmission that drives the GnRH surge through enhanced glutamate neurotransmission.
