Murburn Concept: A Molecular Explanation for Hormetic and Idiosyncratic Dose Responses.

Dose-response : a publication of International Hormesis Society

Parashar A, Gideon DA, Manoj KM.
PMID: 29770107
Dose Response. 2018 May 09;16(2):1559325818774421. doi: 10.1177/1559325818774421. eCollection 2018.

Recently, electron transfers and catalyses in a bevy of redox reactions mediated by hemeproteins were explained by murburn concept. The term "murburn" is abstracted from "

Recent Approaches for Manipulating Globin Gene Expression in Treating Hemoglobinopathies.

Frontiers in genome editing

Mussolino C, Strouboulis J.
PMID: 34713248
Front Genome Ed. 2021 Aug 02;3:618111. doi: 10.3389/fgeed.2021.618111. eCollection 2021.

Tissue oxygenation throughout life depends on the activity of hemoglobin (Hb) one of the hemeproteins that binds oxygen in the lungs and secures its delivery throughout the body. Hb is composed of four monomers encoded by eight different genes...

Rational Design of Novel Pyridinol-Fused Ring Acetaminophen Analogues.

ACS medicinal chemistry letters

Shchepin RV, Liu W, Yin H, Zagol-Ikapitte I, Amin T, Jeong BS, Roberts LJ, Oates JA, Porter NA, Boutaud O.
PMID: 24482730
ACS Med Chem Lett. 2013 Aug 08;4(8):710-714. doi: 10.1021/ml4000904.

Acetaminophen (ApAP) is an electron donor capable of reducing radicals generated by redox cycling of hemeproteins. It acts on the prostaglandin H synthases (cyclooxygenases; COXs) to reduce the protoporphyrin radical cation in the peroxidase site of the enzyme, thus...

Alternate Heme Ligation Steers Activity and Selectivity in Engineered Cytochrome P450-Catalyzed Carbene-Transfer Reactions.

Journal of the American Chemical Society

Chen K, Zhang SQ, Brandenberg OF, Hong X, Arnold FH.
PMID: 30372623
J Am Chem Soc. 2018 Dec 05;140(48):16402-16407. doi: 10.1021/jacs.8b09613. Epub 2018 Nov 01.

We report a biocatalytic platform of engineered cytochrome P450 enzymes to carry out carbene-transfer reactions using a lactone-based carbene precursor. By simply altering the heme-ligating residue, we obtained two enzymes that catalyze olefin cyclopropanation (Ser) or S-H bond insertion...

Heme on innate immunity and inflammation.

Frontiers in pharmacology

Dutra FF, Bozza MT.
PMID: 24904418
Front Pharmacol. 2014 May 27;5:115. doi: 10.3389/fphar.2014.00115. eCollection 2014.

Heme is an essential molecule expressed ubiquitously all through our tissues. Heme plays major functions in cellular physiology and metabolism as the prosthetic group of diverse proteins. Once released from cells and from hemeproteins free heme causes oxidative damage...

SAXS structure of homodimeric oxyHemoglobin III from bivalve Lucina pectinata.

Biopolymers

Marchany-Rivera D, Estremera-Andújar RA, Nieves-Marrero C, Ruiz-Martínez CR, Bauer W, López-Garriga J.
PMID: 33792032
Biopolymers. 2021 Jun;112(6):e23427. doi: 10.1002/bip.23427. Epub 2021 Apr 01.

Hemoglobin III (HbIII) is one of the two oxygen reactive hemoproteins present in the bivalve, Lucina pectinata. The clam inhabits a sulfur-rich environment and HbIII is the only hemoprotein present in the system which does not yet have a...

Mechanisms of Neuronal Damage in Acute Hepatic Porphyrias.

Diagnostics (Basel, Switzerland)

Ricci A, Di Pierro E, Marcacci M, Ventura P.
PMID: 34943446
Diagnostics (Basel). 2021 Nov 26;11(12). doi: 10.3390/diagnostics11122205.

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. neurovisceral, hepatic vs. erythropoietic)...

Hemeprotein amplifies the innate immune receptors of Ctenopharyngodon idellus kidney cells through NF-κB- and MAPK-dependent reactive oxygen species generation.

Developmental and comparative immunology

Lu Z, Tang M, Zhang M, Li Y, Shi F, Zhan F, Zhao L, Li J, Lin L, Qin Z.
PMID: 34273355
Dev Comp Immunol. 2022 Jan;126:104207. doi: 10.1016/j.dci.2021.104207. Epub 2021 Jul 15.

Infectious bacterial and viral diseases that cause hemolysis are considered life-threatening to grass carp (Ctenopharyngodon idellus), which is a species used in aquaculture worldwide. After heme and hemeproteins (Hb) are released as a result of hemolysis, the effect of...

Hyperspectral absorption microscopy using photoacoustic remote sensing.

Optics express

Bell K, Mukhangaliyeva L, Khalili L, Haji Reza P.
PMID: 34614681
Opt Express. 2021 Jul 19;29(15):24338-24348. doi: 10.1364/OE.430403.

An improved method of remote optical absorption spectroscopy and hyperspectral optical absorption imaging is described which takes advantage of the photoacoustic remote sensing detection architecture. A wide collection of photoacoustic excitation wavelengths ranging from 210 nm to 1550 nm...

Hemoproteins-nickel foam hybrids as effective supercapacitors.
