A naturally occurring system for tuning CRISPR-Cas9 expressing in bacteria, identified in a study published in Cell , could have implications for gene editing therapies as well. A CRISPR-Cas9 system has two components: the Cas9 guide RNA that directs the system to edit a particular gene, and the CRISPR “scissors” that make the cut.
Researchers must characterize the anti-drug-antibody (ADA) response in preclinical and clinical studies and report any ADA-positive samples as a risk-based approach. An oligonucleotide is a short strand of nucleotides, the building blocks of DNA or RNA, used in genetic research and therapy.
To date, there are less than 30 known surface proteins that form the basis of all approved cancer-targeted therapies of all modalities, including antibody-drug conjugates (ADCs), T-cell engagers, CAR T-cells and radiopharmaceuticals. These could be targets for antibody-drug conjugates (ADCs), bi-specific antibodies, or other therapies.
For example, PROTACs targeting STAT3, a protein crucial for tumor growth, have shown promise where conventional therapies have failed. The versatility and potential of PROTACs are vast, paving the way for new therapies that could transform how we treat diseases.
While RA therapies targeted to specific inflammatory pathways have emerged, only some patients’ symptoms improve with treatment, emphasizing the need for multiple treatment approaches tailored to different disease subtypes. They also found that patients’ CTAPs were dynamic and could change over time in response to treatment.
This gives epigenetic editing the unique ability to treat complex multigenic diseases and opens the door to enhancing cell and regenerative therapies, which require the manipulation of multiple genes for optimal results.
