New class of protein materials can influence cell signaling

A new study has revealed that a novel class of protein material that communicates with living cells without being absorbed by them can affect cell signaling. The protein material does this by attaching and sequestering cell surface receptors.

Researchers create molecular ON-OFF switches to regulate CAR T cell activity

CAR T cells are a breakthrough class of effective but often toxic cancer therapies. To prevent overactivation, switchable CAR T cells were engineered that can be turned on and off with an approved, widely used cancer drug.

Study addresses mystery of how chromosomes are inherited during cell division

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within this intricate process is the transfer of DNA through each subsequent cell split within discrete packets called chromosomes.

Sugar-binding protein could serve as a useful biomarker for patients at risk of sepsis

According to a research team headed by the University of Connecticut Health, a sugar-binding protein could drive terrible inflammation and worsen sepsis—a disease that kills over 270,000 individuals per year in the United States alone.

Study shows that hemoglobin in several species descends from a single gene

The marine worm Platynereis dumerilii has enabled researchers from CNRS, Université de Paris, Sorbonne Université, University of Saint Petersburg, and the University of Rio de Janeiro to demonstrate that hemoglobin appeared independently in several species and actually evolved from a single gene transmitted to all by their last common ancestor.

Combination method can boost immunotherapy for breast cancer

According to a new study performed by scientists from the University of North Carolina, stimulating an immune signaling pathway, which is best known for combating bacterial and viral infections, can increase the potential of genetically engineered T cells to remove breast cancer in mice.

Twist‐and‐squeeze mechanism of transporter protein confers cancer drug resistance

In 1986, cellular biochemist Kazumitsu Ueda, currently at Kyoto University's Institute for Integrated Cell-Material Sciences, discovered that a protein called ABCB1 could transport multiple chemotherapeutics out of some cancer cells, making them resistant to treatment. How it did this has remained a mystery for the past 35 years.

Chromosomal instability is associated with cancer's aggressiveness

Cancer cells are known for spreading genetic chaos. As cancer cells divide, DNA segments and even whole chromosomes can be duplicated, mutated, or lost altogether.
