New videos show RNA as it’s never been seen

A new Northwestern University-led study is unfolding the mystery of how RNA molecules fold themselves to fit inside cells and perform specific functions. The findings could potentially break down a barrier to understanding and developing treatments for RNA-related diseases, including spinal muscular atrophy and perhaps even the novel coronavirus. “RNA folding is a dynamic process […]

Scientists study use of abundant enzyme in tumor cells to monitor cancer treatment

IMAGE: The team led by Carmen Ferreira-Halder at Unicamps Bioassay and Signal Tranduction Laboratory conclude that the molecule is associated with chemotherapy resistance and metastasis. view more  Credit: Roberta Ruela de Souza The abundant presence of an enzyme known as low molecular weight protein tyrosine phosphatase (LMWPTP) in tumor cells has long been considered an indicator […]

FAU develops simplified COVID-19 diagnostic method to ramp up widespread testing
