Cell signaling is vital for cells to communicate and coordinate their activities, not just in the human body, but in all organisms. There are thousands of signaling pathways, ranging from protein homeostasis to carcinogenesis and biofilm formation.

Study elucidates mechanisms behind G protein selectivity and efficacy in adenosine A2A receptor

In a groundbreaking study, a multinational research team led by Dr. Adnan Sljoka (RIKEN) and Prof. Akio Kitao (Tokyo Tech), in collaboration with Prof. Scott Prosser (University of Toronto), has carried out experimental and computational studies to elucidate the mechanisms behind G protein selectivity and efficacy in the human adenosine A2A receptor (A2AR).

Innovative dual-drug strategy for colorectal cancer treatment

A combination of two drugs was capable of suppressing tumors in a non-conventional manner. Instead of inhibiting tumor cell division, as the most widely used medications do, the strategy consisted of hyperactivating oncogenic signaling by these cells to the point where they became stressed.

Breakthrough research identifies fibrin as key factor in preterm brain bleeds

Mark Petersen, MD, has seen firsthand the devastating effects of brain bleeds in premature babies. It's an exceedingly common condition that affects up to 20 percent of infants born before 28 weeks of gestation, bringing an increased risk for developmental delays and autism.

Ribosomes and ZAK protein spur the cell's initial response to UV radiation damage

In a recent study, researchers at Johns Hopkins Medicine suggest the cell's messenger RNA (mRNA) - the major translator and regulator of genetic material - along with a critical protein called ZAK, spur the cell's initial response to UV radiation damage and play a critical role in whether the cell lives or dies.
