MicroRNA’s influence on lupus disease inflammation

Researchers from Nagoya University’s Graduate School of Medicine in Japan have uncovered how microRNA (miRNA) affects inflammation in mice with lupus. They discovered two downregulated miRNAs in the disease along with a rare circumstance where several miRNAs control the same set of genes.

Detecting the extent of natural selection over time

Institut Pasteur, Université Paris Cité, the CNRS, and the Collège de France researchers have employed paleogenomics to trace 10,000 years of human immune system evolution. They examined the genomes of over 2,800 individuals who lived in Europe over the past 10 millennia.

Insights into the role of the germline in de novo mutation

The male reproductive system is a hotspot for the introduction of new genes. Perhaps that might assist in understanding why fathers tend to pass on more new mutations than mothers do. However, it does not explain why older fathers pass on more mutations than younger fathers.

Designing plants through more-sophisticated genetic editing

Genetic manipulation was used by humans for millennia, long before they worked in lab coats Selective breeding has been employed for a very long time to produce plants and animals of great value, from adorable dogs to palatable fruit.

Scandinavian gene pool development via DNA analysis

The complex relationships between geography, ancestry, and gene flow in Scandinavia are resolved in a new study based on 297 ancient Scandinavian genomes that were analyzed along with the genomic data of 16,638 modern Scandinavians.

Revealing the unappreciated role of POLQ in responding to DNA replication stress

Researchers at the Francis Crick Institute, in partnership with Artios, have discovered how an enzyme involved in DNA repair (POLQ) becomes critical to the survival of some tumors when the cancer cells lose the ability to employ a more frequent way of DNA repair.
