Scientists study use of abundant enzyme in tumor cells to monitor cancer treatment
Publicado em 12 janeiro 2021
The abundant presence of an enzyme known as low molecular weight protein tyrosine phosphatase (LMWPTP) in tumor cells has long been considered an indicator of cancer aggressiveness and metastatic potential. It is also known to perform important functions in cells under normal conditions, participating in both the proliferation process and the regulation of intracellular systems. Research continues on its role in cancer progression.
In Brazil, a group of researchers at the University of [...]

‘New evidence’ shows how acute stress can lead to grey hair
Publicado em 23 janeiro 2020Scientists believe they have uncovered “new evidence” that shows how acute stress can cause hair to turn white prematurely. Mice experiments have revealed that extreme levels of stress causes the sympathetic nervous system, which is responsible for the body’s rapid involuntary response to dangerous or stressful situations, to become hyperactive. This, in turn, drives the rapid depletion of stem cells responsible for hair colour, leading to pigment loss and development of [...]ver notícia
