This article was review by Thomas Cooper, MD from Baylor College of Medicine. Stay up to date on the latest science with Brush Up Summaries. Despite its significance, alternative splicing’s global ...

Alternative splicing, a clever way a cell generates many different variations of messenger RNAs -- single-stranded RNAs involved in protein synthesis -- and proteins from the same stretch of DNA, ...

Genes contain the essential building instructions for life, guiding cells on which amino acids to assemble in what sequence to produce specific proteins. The human genome codes for about 20,000 such ...

What kills most people who die from cancer is not the initial tumor. It’s the intolerable disease burden on the body that arises when tumor cells continually expand their numbers after spreading to ...

Alternative splicing is a genetic process where different segments of genes are removed, and the remaining pieces are joined together during transcription to messenger RNA (mRNA). This mechanism ...

USP39 stabilizes the spliceosome (green), which cuts out unneeded parts (grey and purple) of the mRNA. If USP39 is missing, some of the mRNA is poorly processed. This results in misfolded proteins, ...

Pre-mRNA splicing in a subset of human short introns is governed by a distinct mechanism involving a new splicing factor, new research finds. The interrupted non-coding regions in pre-mRNAs, termed ...

Pancreatic ductal adenocarcinoma (PDAC) is the most common form of pancreatic cancer. More than 90% of PDAC patients die within five years of diagnosis. Usually, by the time the cancer is identified, ...

While humans can escape the heat by seeking shade or shedding layers, plants remain rooted in place. So how do they survive extreme heat? It’s a question many have wondered—and now, science has an ...
