– Epic’s non-cutting technology to modulate the epigenome advances with the addition of new hypercompact Cas effectors and potent gene activators –
SOUTH SAN FRANCISCO, Calif. — August 17, 2023 — Epic Bio, a biotechnology company developing therapies to modulate gene expression using compact, non-cutting dCas proteins, today presented new data on its epigenetic editing platform at Cold Spring Harbor Laboratory’s Genome Engineering: CRISPR Frontiers conference, being held August 16-20, 2023, in Cold Spring Harbor, NY.
Epic’s six poster presentations detail a variety of discoveries that expand upon the capabilities of the company’s powerful Gene Expression Modulation System (GEMS) platform. Specifically, Epic is presenting the first disclosures of the results of their in-house protein engineering efforts to improve upon CasMINI, the smallest Cas protein known to work in human cells. Epic generated novel Cas effectors even smaller than CasMINI, under 500 amino acids in size, and with improved epigenetic editing activity. These hypercompact CRISPR components can enable packaging within a single AAV and delivery of multiple modulators simultaneously.
Additionally, Epic will highlight new research identifying combinations of epigenetic activators that display synergistic activity, increasing gene expression more than the sum of their parts. Epic screened hundreds of transcription-activating peptides for robust combinatorial activity, then applied machine learning to predict combinations with the greatest effect on gene expression. These insights will allow Epic to design multiplexed GEMS constructs with improved activity.
Full details of the posters are as follows. The presentations will be made available under the publications section of the Science page on the Epic Bio website.
