Can gene therapy slow aging?
Some early-stage studies suggest targeting telomerase, FOXO3, or mitochondrial genes may extend healthspan — but human trials are limited.
Learn more →
What is somatic vs germline gene editing?
Somatic edits affect only the individual; germline changes are heritable and affect future generations — the latter is ethically controversial.
Learn more →
What longevity genes are being studied?
Examples include FOXO3, SIRT1, KL (Klotho), TERT, and PGC-1α for their roles in DNA repair, mitochondria, and stress resistance.
Learn more →
What is epigenetic editing?
It modifies gene expression without changing the DNA sequence, offering reversible and more targeted therapeutic potential.
Learn more →
What delivery methods are used in gene therapy?
Common methods include viral vectors (AAV, lentivirus), lipid nanoparticles, and electroporation.
Learn more →
Are there risks or side effects?
Yes — immune reactions, off-target mutations, and insertional mutagenesis are potential concerns in gene editing.
Learn more →
What are the ethical issues with CRISPR?
Concerns include equity of access, unintended consequences, and modifying human embryos without long-term safety data.
Learn more →
Has CRISPR been used in humans?
Yes — clinical trials have tested CRISPR in sickle cell disease, cancer immunotherapy, and hereditary blindness with promising results.
Learn more →
What is base editing vs prime editing?
Base editing alters a single DNA letter; prime editing allows precise edits without cutting both DNA strands — both are next-gen CRISPR tools.
