Mechanisms of Neuronal Damage in Acute Hepatic Porphyrias

open access: yesDiagnostics, 2021
Porphyrias are a group of congenital and acquired diseases caused by an enzymatic impairment in the biosynthesis of heme. Depending on the specific enzyme involved, different types of porphyrias (i.e., chronic vs. acute, cutaneous vs.

Optimization of Hnox Protein Production in Escherichia Coli

open access: yesCumhuriyet Science Journal, 2017
Hemeproteinscarry a variety of different functions in organisms ranging from steroidbiosynthesis to respiration, signaling to drug metabolism. In industry,hemeproteins are used for production of drugs such as: pravastatin for loweringcholesterol ...

Hypoxic Regulation of the Large-Conductance, Calcium and Voltage-Activated Potassium Channel, BK

open access: yesFrontiers in Physiology, 2021
Hypoxia is a condition characterized by a reduction of cellular oxygen levels derived from alterations in oxygen balance. Hypoxic events trigger changes in cell-signaling cascades, oxidative stress, activation of pro-inflammatory molecules, and growth ...

Hydrogen Sulfide and Hemeproteins: Knowledge and Mysteries [PDF]

open access: yesAntioxidants & Redox Signaling, 2011
Historically, hydrogen sulfide (H(2)S) has been regarded as a poisonous gas, with a wide spectrum of toxic effects. However, like ·NO and CO, H(2)S is now referred to as a signaling gas involved in numerous physiological processes. The list of reports highlighting the physiological effects of H(2)S is rapidly expanding and several drug candidates are ...

Critical role for uricase and xanthine dehydrogenase in soybean nitrogen fixation and nodule development

open access: yesThe Plant Genome, Volume 16, Issue 2, June 2023., 2023
Abstract De novo purine biosynthesis is required for the incorporation of fixed nitrogen in ureide exporting nodules, as formed on soybean [Glycine max (L.) Merr.] roots. However, in many cases, the enzymes involved in this pathway have been deduced strictly from genome annotations with little direct genetic evidence, such as mutant studies, to confirm

New insights into the role of heme oxygenase-1 in acute kidney injury

open access: yesKidney Research and Clinical Practice, 2020
Acute kidney injury (AKI) is attended by injury-related biomarkers appearing in the urine and serum, decreased urine output, and impaired glomerular filtration rate.

Encapsulation of sugar beet phytoglobin BvPgb 1.2 and myoglobin in a lipid sponge phase system

open access: yesFrontiers in Soft Matter, 2023
Globins are usually associated with oxygen carriage in vertebrates. However, plants also contain similar heme-containing proteins, called phytoglobins (Pgbs).

Label-free photoacoustic microscopy of cytochromes [PDF]

open access: yes, 2013
Photoacoustic microscopy (PAM) has achieved submicron lateral resolution in showing subcellular structures; however, relatively few endogenous subcellular contrasts have so far been imaged. Given that the hemeprotein, mostly cytochromes in general cells,

The effects of nitroxyl (HNO) on soluble guanylate cyclase activity: interactions at ferrous heme and cysteine thiols [PDF]

open access: yes, 2009
It has been previously proposed that nitric oxide (NO) is the only biologically relevant nitrogen oxide capable of activating the enzyme soluble guanylate cyclase (sGC). However, recent reports implicate HNO as another possible activator of sGC.
