Biochemical methods reveal signal transduction mystery inside human pathogen

In order to adapt to the changing environment, bacteria must quickly transform extracellular information into appropriate intracellular reactions. Two component system (TCS) is the main signal transduction protein in prokaryotic cells to transform environmental stimuli into cellular responses.

New combination therapy could be effective in treating aggressive cancers with common mutations

Scientists have long known that therapies that target the cancer-driving MAPK pathway are only effective in a handful of cancers with specific mutations in a cancer gene called BRAF, and these cancers that initially respond to the therapy often end up developing resistance to the treatment, resulting in relapse for many patients.

Study shows tRNA fragments play a key role in ischemic stroke

An ischemic stroke occurs when the homeostasis of the body and brain is highly disrupted. The immune system, among other things, activates an inflammatory response that can either overshoot or change into an immune deficiency.
