The use of mtCOI gene sequences in identifying Butis species in the Southwest of Vietnam

open access: yesHeliyon, 2023
Butis genus is characterised by their small body size and morphological variability, allowing them to adapt to different habitats. This paper analyses the mitochondrial cytochrome C oxidase subunit I gene sequences and morphology of Butis for ...

Vibrational structure of the formyl group on heme a. Implications on the properties of cytochrome c oxidase

open access: yesBiophysical Journal, 1991
Resonance Raman spectra have been recorded for heme a derivatives in which the oxygen atom of the formyl group has been isotopically labeled and for Schiff base derivatives of heme a in which the Schiff base nitrogen has been isotopically labeled. The 14N-15N isotope shift in the C = N stretching mode of the Schiff base is close to the theoretically ...

Effect of Red Dragon Fruit Extract Ingestion on Mitochondrial Cytochrome c Levels in Rat Soleus Muscle Following Moderate Exercise

open access: yesAlthea Medical Journal
Background: Exercise-induced free radicals harm cellular mitochondria and trigger apoptosis via cytochrome-c release. Red dragon fruit (RDF) extract is known for its potent antioxidant properties. This study aimed to investigate whether RDF extract could

Structure of an electron transfer complex. II. Chemical modification of carboxyl groups of cytochrome c peroxidase in presence and absence of cytochrome c.

open access: yesJournal of Biological Chemistry, 1985
Cytochrome c peroxidase forms an electron transfer complex with cytochrome c. The complex is governed by ionic bonds between side chain amino groups of cytochrome c and carboxyl groups of peroxidase. To localize the binding site for cytochrome c on the peroxidase, we have used the method of differential chemical modification.

Leukemia and Exposure to Potential Benzene Sources in Children From the Mexico City Metropolitan Area, 2010–2021: A Geospatial Analysis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Leukemia is the most common childhood cancer in Mexico, and acute lymphoblastic leukemia (ALL) is the most frequent subtype. Exposure to high concentrations of benzene has been associated with ALL incidence, particularly in urban areas. This study evaluated the relationship between distance to benzene emission sources and the number

Maturation of Plastid c-type Cytochromes

open access: yesFrontiers in Plant Science, 2017
Cytochromes c are hemoproteins, with the prosthetic group covalently linked to the apoprotein, which function as electron carriers. A class of cytochromes c is defined by a CXXCH heme-binding motif where the cysteines form thioether bonds with the vinyl ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Interferon beta drives therapy resistance in a patient‐derived model of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Interferon type 1 (IFN‐1) production and signaling is associated with the acquisition of therapy resistance, following chronic DNA damage, via Interferon‐related DNA damage resistance signature (IRDS) gene expression. An alternative, DNA damage‐independent role of sustained IFN‐1 mediated resistance was identified and characterized by the emergence of ...

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

open access: yesFEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs
