Leishmania major Peroxidase Is a Cytochrome c Peroxidase [PDF]

Biochemistry, 2012
Leishmania major peroxidase (LmP) exhibits both ascorbate and cytochrome c peroxidase activities. Our previous results illustrated that LmP has a much higher activity against horse heart cytochrome c than ascorbate, suggesting that cytochrome c may be the biologically important substrate.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Peroxidase-like Nanozymes for Point-of-Care SERS Sensing and Wound Healing [PDF]

, 2023
The emergence of nanozymes provides a potential method for combating multidrug-resistant bacteria resulted from the abuse of antibiotics. However, in nanozyme-catalyzed systems, few studies have addressed the actual hydrogen peroxide (H2O2) level ...

Results in the determination of some Hosta varieties by the method of isoelectric focusing

International Journal of Horticultural Science, 2001
Mass propagation of 5 newly introduced Hosta varieties was carried out by the method of micropropagation. Our aim was to determine exact variety specificity after the micropropagation period in the pattern of peroxidase isoenzymes by isoelectric focusing

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

The preparation and characterisation of novel microperoxidase biocatalysts [PDF]

, 1987
Microperoxidases are haem oligopeptides, derived from the proteolytic digestion of cytochrome c, possessing peroxidase activity. They are termed "microperoxidases" in contrast to other relatively large peroxidases such as horseradish peroxidase.

The Estimation of the Antioxidant Enzymes Activity in Representatives of Different Populations of Lymnaea stagnalis Differ in the Degree of Infestation Under Temperature Stress [PDF]

Journal of Stress Physiology & Biochemistry, 2016
The aim of this study was to assess the impact of effects of thermal stress and parasitic infestation on the activity of antioxidant enzymes (peroxidase, catalase and glutathione S-transferase) in different populations of wide-spread species of pulmonate

Changes of antioxidant enzymes of mung bean [Vigna radiata (L.) R. Wilczek] in response to host and non-host bacterial pathogens

Journal of Plant Protection Research, 2016
The natural resistance against the majority of potential pathogens that exist in most plant species is known as non-host resistance. Several reports suggest the role of antioxidant enzymes in non-host resistance.
