BACKGROUND
Reperfusion of the liver after ischemia induces the expression of the heat shock genes and the synthesis of the heat shock proteins (HSP). We studied the effects of the natural antioxidant ergothioneine (EGT) treatment on the expression of HSP70 in ischemic-reperfused (IR)
OBJECTIVE
Ergothioneine (EGT) is a natural compound that is synthesized by soil bacteria in fungal substrates and exhibits antioxidant functions in many cell models. The purpose of this study was to investigate the effect of EGT on mesenteric ischemia and reperfusion injury.
METHODS
Rats were
Ergothioneine, a natural thiol-containing molecule, has recently been proposed to protect the heart against damage caused by ischaemia and reperfusion. We investigated the possibility that ergothioneine can have a role in maintaining the myocardial thiol/disulfide balance and consequently also a
Infection with SARS-CoV-2 causes the coronavirus infectious disease 2019 (COVID-19), a pandemic that has, at present, infected more than 11 million people globally. Some COVID-19 patients develop a severe and critical illness, spurred on by excessive inflammation that can lead to respiratory or
Preeclampsia is a multifactorial hypertensive disorder of pregnancy founded on abnormal placentation, and the resultant placental ischemic microenvironment is thought to play a crucial role in its pathophysiology. Placental ischemia because of fluctuations in the delivery of oxygen results in
In this paper, we demonstrate that ergothioneine (ES), a naturally occurring thiolhistidine, reduces ferrylmyoglobin (MbIV) to MbIII when the former (ferryl species) is produced by exposing either deoxy MbII or MbIII to H2O2. The reduction of MbIV to MbIII by ES yields the disulfide of ES which the
Reflectance spectroscopy was utilized to monitor the oxidation states of myoglobin (Mb) in isolated, buffer-perfused rat hearts. Hearts were subjected to 30 min global, no-flow ischemia, followed by reperfusion under anoxic conditions. The addition of Na2S to the buffer at reperfusion permitted the
OBJECTIVE
Solute carrier OCTN1 (SLC22A4) is an orphan transporter, the physiologically important substrate of which is still unidentified. The aim of the present study was to examine physiological roles of OCTN1.
METHODS
We first constructed octn1 gene knockout (octn1 ( -/- )) mice. Metabolome
