Developing a potential drug molecule that targets STAT5

STAT5 has generally been recognized as an enticing cancer target, but after years of research, it was downgraded to the “undruggable” category. Now, scientists at the University of Michigan Rogel Cancer Center have achieved success with a novel approach.

WashU researcher receives NIH grant to study a poorly understood protein linked to ALS

The relentless neurological disease amyotrophic lateral sclerosis (ALS) eventually shuts down the entire body, but the devastation starts at a molecular level.

Identifying the molecular switch that regulates autophagy in plants

Autophagy, commonly known as “self-eating,” is a cellular quality control mechanism that relieves the cell of protein aggregates and damaged organelles. This system is inert under ordinary conditions and is only activated in the presence of persistent cellular stress.

Innovative cancer therapy options with new cell death mechanism

Researchers from The University of Texas MD Anderson Cancer Center have described a previously unrecognized type of cell death called disulfidptosis in a study that was published in Nature Cell Biology.

New hexameric structure of the protein triggering antibiotic resistance discovered

All living organisms require DNA replication to ensure the genetic integrity of the following generation. On the other hand, bacteria have the ability to horizontally transfer genetic information to other bacteria.

Structure of amyloid fibers formed by the protein hnRNPDL-2 determined

Using high-resolution cryo-electron microscopy (cryo-EM), UAB researchers determined the structure of amyloid fibers formed by the protein hnRNPDL-2, which has been linked to limb-girdle muscular dystrophy type 3 and concluded that the protein’s inability to form amyloid ﬁbers, rather than aggregation, would be the cause of the disease.

AI develops first-ever functional artificial protein

Scientists have developed an AI system that can produce artificial enzymes from scratch. Even though several of these enzymes’ artificially generated amino acid sequences differed noticeably from those of any known natural protein, they nonetheless performed as well in laboratory testing as those found in nature.

New open-access database provides a map of the proteome signature

The recently released cancer protein profile database, which was created using AI and machine learning, has helped with cancer prediction medicine. The new open-access Disease Blood Atlas, unveiled by KTH Royal Institute of Technology Professor Mathias Uhlén, gives the first-ever map of the proteome signature in cancer patients’ blood.

Novel insights into the elongation dynamics of eukaryotic cells

The proper functioning of numerous proteins generated in cells by ribosomes is essential for life. This diversified variety of proteins, called proteome, is sustained by the ribosomes’ vigorous translation elongation of amino acid sequences.

The genetic mechanisms that induce protein decline in modern maize

The wild ancestor of maize, teosinte, contains three times as much seed protein as the majority of cultivars of maize today. The mechanisms causing the declining seed protein content in maize hybrids and inbred lines were identified by researchers at the Chinese Academy of Sciences Headquarters.
