Environmental DNA. Although the mechanisms are unclear, cells are known to pull in external DNA molecules under the right conditions. That means DNA in the environment—from shed skin, mucus, spawned ...

Gene expression in the human brain: cell types become more specialized, not just more numerous Date: January 2, 2025 Source: University of California - Santa Barbara ...

Scientists investigate disease targets by studying gene expression data often obtained by assaying entire cell populations. For instance, researchers used bulk RNA sequencing to discover druggable ...

It’s based on a protein called Fanzor, and this new finding is the first programmable RNA-guided system discovered in eukaryotes. The new RNA-editing system is described in a study published ...

The differences in gene expression suggested that the reptilian DVR and the mammalian neocortex evolved independently from different regions of the brain. “The 2018 paper was really a landmark paper ...

From these gene expression profiles, evolutionary neuroscientists can identify a wealth of detailed differences between individual neurons. They can use those differences to determine how ...

A trio of bioengineering scientists at Ecole Polytechnique Fédérale de Lausanne has found age and gender differences in gene expression related to the circadian clock. For their paper published ...

Daily rhythms of gene expression in humans vary according to sex and age, according to a new study using more than 900 human transcriptomes from the Genotype-tissue Expression (GTEx) project. The ...

A study published in the journal Cell marks the first reported instance of generative AI designing synthetic molecules that can successfully control gene expression in healthy mammalian cells.

To address the clinical need to aid in identifying patients at low or high risk of melanoma-specific survival (MSS) death, the DecisionDx-Melanoma prognostic test (31-gene expression profile; 31-GEP) ...
