Potassium extrusion by plant cells: evolution from an emergency valve to a driver of long‐distance transport

New Phytologist, Volume 245, Issue 1, Page 69-87, January 2025.
Summary The ability to accumulate nutrients is a hallmark for living creatures and plants evolved highly effective nutrient transport systems, especially for the uptake of potassium (K+). However, plants also developed mechanisms that enable the rapid extrusion of K+ in combination with anions.

N‐cadherin: A diagnostic marker to help discriminate primary liver carcinomas from extrahepatic carcinomas

International Journal of Cancer, Volume 154, Issue 10, Page 1857-1868, 15 May 2024.
What's new? A diagnostic marker capable of distinguishing primary liver cancer from liver metastases of extrahepatic origin remains elusive. Of particular interest as a marker, however, is N‐cadherin, an adherens junction transmembrane glycoprotein normally expressed by hepatocytes and cholangiocytes.
