From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

open access: yesAdvanced Science, EarlyView.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

Proton-transfer pathways in the mitochondrial S. cerevisiae cytochrome c oxidase

open access: yesScientific Reports, 2019
In cytochrome c oxidase (CytcO) reduction of O2 to water is linked to uptake of eight protons from the negative side of the membrane: four are substrate protons used to form water and four are pumped across the membrane.

Vectorially Oriented Monolayers of the Cytochrome c/Cytochrome Oxidase Bimolecular Complex

open access: yes, 1998
Vectorially oriented monolayers of yeast cytochrome c and its bimolecular complex with bovine heart cytochrome c oxidase have been formed by self-assembly from solution.

Conformational Snapshots of CydDC in a Native Lipid Bilayer Coupling Heme Transport to Antibiotic Resistance

open access: yesAdvanced Science, EarlyView.
Phylogenetic and biochemical analyses of the heme transporter CydDC reveal its functional conservation throughout bacterial evolution and demonstrate its unique asymmetric allosteric mechanism. Furthermore, impairment of CydDC function directly affects bacterial antibiotic resistance and likely compromises antibiotic efficacy through drug efflux.

Investigation of in vivo measurement of cerebral cytochrome-c-oxidase redox changes using near-infrared spectroscopy in patients with orthostatic hypotension

open access: yes, 2007
We have previously used a continuous four wavelength near infrared spectrometer to measure changes in the cerebral concentrations of oxy- (Δ[HbO2] and deoxy- haemoglobin (Δ[HHb]) during head-up tilt in patients with primary autonomic failure.

Unraveling a Diagnostic Enigma: A TECPR2 Case Solved Through Multi‐Omic Genomics

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT TECPR2 is a key regulator of autophagy, encoded by the TECPR2 gene. Pathogenic variants in this gene have been linked to a rare hereditary sensory and autonomic neuropathy with intellectual disability (HSAN9). We report a teenage female with a syndromic intellectual disability disorder associated with neuromuscular abnormalities.

Association of bacterial respiratory complexes

open access: yes, 2007
The mitochondrial respiratory chain consists of NADH:ubiquinone oxidoreductase (Complex-I), succinate:ubiquinone reductase (Complex-II), ubiquinol:cytochrome c reductase (Complex-III), cytochrome c oxidase (Complex-IV) and cytochrome c as an electron ...

One‐step generation of heritable mitochondrial DNA multiplex‐engineered rats using DddA‐derived cytosine base editor

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We established that mixed DdCBE microinjection is an efficient, heritable, and precise strategy for generating multiplex mtDNA mutant rats. This advancement significantly expands the utility of DdCBEs for mitochondrial disease modeling, providing a robust platform for exploring the pathogenic mechanisms of complex mtDNA mutations and developing ...

CYCLOPHOSPHAMIDE HEPATOTOXICITY: THE ROLE OF 4-HYDROXYNONENAL AND CYTOCHROME C OXIDASE AND THE POSSIBLE PROTECTIVE EFFECT OF GANODERMA LUCIDUM EXTRACT

open access: yesSlovenian Veterinary Research, 2019
Cyclophosphamide (CPA) is a widely used anti-neoplastic drug, but its usage is associated with several side effects including hepatotoxicity. This study was designed to evaluate the ameliorative effect of Ganoderma lucidium (GL) extract as a natural ...

Analysis of the Changes in the Oxidation of Brain Tissue Cytochrome-c-Oxidase in Traumatic Brain Injury Patients during Hypercapnoea A Broadband NIRS Study

open access: yes, 2011
Using broadband near-infrared spectroscopy (NIRS) and cerebral micro-dialysis (MD), we investigated cerebral cellular metabolism and mitochondrial redox states, following hypercapnoea in 6 patients with traumatic brain injury (TBI).
