How do different tissues silence different genes? In CRISPRi, genes are silenced by a potent repressor TRIM28; we discovered a special version, TRIM66, that is only expressed in nose, testis, & cancer. It controls smell & behaviors. Now in @NatureComms:

Today in @Nature we report a new prime editing strategy that can rescue a common cause of many genetic diseases in a disease-agnostic manner. This approach converts a redundant endogenous tRNA into an optimized suppressor tRNA, enabling a single prime edit to rescue premature

Enjoyed reading the recent paper from gnomAD team on the modifiers of penetrance of clinically-relevant variants in 800k individuals in the gnomAD database. One example highlighted in the paper is extremely fascinating! It's a beautiful example of a loss of function (LOF)

For over 20 years, the mouse model organism has helped scientists uncover the biology behind human health and disease. But the mouse reference genomes still have missing pieces. The first collection of telomere-to-telomere mouse genomes are available for two key mouse strains.

The quest to make babies with lab-grown eggs and sperm. An excellent news feature by Nature: tempered optimism, with critical caveats underscored. And great to see commentary from so many names in the field! https://t.co/WKIsKUB6OQ

The human genome encodes 391 odorant receptor genes. Most of the proteins they encode, though, haven't been expressed in vitro. We don't know what they sense. A new study reports a better way to express odorant receptors in the lab. The authors find receptors for
