Calredoxin regulates the chloroplast NADPH-dependent thioredoxin reductase in <i>Chlamydomonas reinhardtii</i> Open
Calredoxin (CRX) is a calcium (Ca2+)-dependent thioredoxin (TRX) in the chloroplast of Chlamydomonas (Chlamydomonas reinhardtii) with a largely unclear physiological role. We elucidated the CRX functionality by performing in-depth quantita…

Adaptation of the Oxygen Sensing System during Lung Development Open
During gestation, the most drastic change in oxygen supply occurs with the onset of ventilation after birth. As the too early exposure of premature infants to high arterial oxygen pressure leads to characteristic diseases, we studied the a…
