PIEZO1-related Hereditary Xerocytosis Red Blood Cell proteomics


ABSTRACT: Proteome of purified erythrocytes from blood samples from patients diagnosed with a PIEZO1-HX based on familial history, non-spherocytic chronic hemolysis, typical osmotic gradient ektacytometry and molecular testing and from healthy donors were analyzed by a label free quantification approach.

Hereditary xerocytosis is a dominant red cell membrane disorder characterized by an increased leak of potassium from the inside to outside the red blood cell membrane, associated with loss of water leading to red cell dehydration and chronic hemolysis. 90% of cases are related to heterozygous gain of function mutations in PIEZO1, encoding a mechanotransductor that translates a mechanical stimulus into a biological signaling. Data are still required to understand better PIEZO1-HX pathophysiology.  ...[more]
