帕金森病（PD）与黑色素瘤的关联机制不明，研究人员开展 α-Synuclein（αSyn）在黑色素瘤中作用的研究。结果显示，αSyn 在黑色素瘤核仁富集，参与 DNA 双链断裂（DSB）修复，影响细胞增殖等。该研究为理解二者关联提供依据，有重要意义。

Mitochondrial diseases, arising from mutations in mitochondrial DNA (mtDNA), are a diverse group of disorders that lead to ...

“Instead of floating freely and risking uneven distribution, the 2-micron plasmid has evolved a clever trick of hitchhiking,” ...

Hajun Kim, Taejoon Kwon, and Joo Hun Kang—from the Department of Biomedical Engineering at UNIST has unveiled a novel diagnostic technique that utilizes artificially designed polymers known as peptide ...

For decades, scientists believed modern humans descended from a single ancestral lineage. However, new research has not only challenged this view, it has simultaneously spawned a new mystery ...

to "barcode" ribosomal RNA (rRNA) inside living cells. By writing genetic information directly into the 16S rRNA - a molecule universally found in bacteria - the researchers could track which microbes ...

Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active regulator of gene expression at the level of protein biosynthesis.

We’ve long known the short-term effects of trauma — headaches, changes in appetite or sleep, fear, anxiety and concentration troubles are just a few. A new study suggests that severe trauma ...

In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive antibiotic resistance and even shape entire ecosystems. Now an interdisciplinary ...

All modern humans share DNA from two ancient populations that split 1.5 million years ago and reunited through interbreeding about 300,000 years ago. The genetic mixture is approximately 80% from one ...
