Thus, gene expression in eukaryotes is highly variable, depending on the type of activators involved and what signals are present to control binding. The Role of Chromatin.

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 ...

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 ...

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 ...

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 ...

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 ...

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 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 ...

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 ...

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.

Gene expression leading to alterations in the DNA caused by asbestos exposure may explain the development of malignant pleural mesothelioma (MPM), a rare and aggressive cancer. By analyzing public ...

Researchers at the Jackson Laboratory (JAX), the Broad Institute of MIT and Harvard, and Yale University, have used artificial intelligence (AI) to design thousands of new DNA switches that can ...
