Microsomal cytochrome P450 1A1 dependent monooxygenase activity in guinea pig heart: induction, inhibition, and increased activity by addition of exogenous NADPH–cytochrome P450 reductase

open access: yes, 1993
Characterization of cytochrome P450 1A1 dependent monooxygenases in guinea pig heart revealed low rates of 7-ethoxyresorufin O-deethylation, which are markedly increased (20-fold) by treatment with β-naphthoflavone, a poly cyclic aromatic hydrocarbon ...

Immortalization of Human Adult Alveolar Epithelial Cells to Study Environmental Exposures of the Distal Lung

open access: yesCurrent Protocols, Volume 6, Issue 5, May 2026.
Abstract Alveolar epithelial cell type 1 (AT1) and type 2 (AT2) cells make up the saccular gas exchange units of the lung, called alveoli. Formation of alveoli during lung development accounts for the expansive surface area of the lung, allowing for proper respiration and delivery of oxygen to the body.

Resveratrol for Cancer Radio‐Sensitization: Ready for Prime Time or Future Perspective

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
Resveratrol exerts antioxidant and anti‐inflammatory effects by reducing reactive oxygen species and suppressing NF‐κB and JAK/STAT signaling pathways. It modulates metabolic signaling through AMPK‐dependent inhibition of mTOR, influencing cell survival and inflammatory responses.

Heterologous expression and purification of rat cytochrome P450 1A1 [PDF]

open access: yes, 2013
Cytochrome P450 1A1 belongs to "superfamily" of cytochromes P450 (CYPs). It is an extrahepatic enzyme that takes a part in detoxification metabolism of many xenobiotics but unfortunately also it is one of the most important representatives of CYPs ...

Polymorphism of the cytochrome P-450 1A1 (A2455G) in women with breast cancer in Eastern Azerbaijan, Iran [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2014
Objective(s):Cytochrome P-450 1A1 is an important enzyme in the first phase of the metabolism of some carcinogens such as polycyclic aromatic hydrocarbons (PAHs), as well as estrogen.

Phylogenetic Analysis and In Silico Characterization of Cytochrome P450 1A (Cyp1A) Protein from the African Catfish, Clarias gariepinus (Burchell, 1822)

open access: yesNotulae Scientia Biologicae, 2019
The CYP family enzymes are broadly used as biomarkers because of their pattern of expression. This study describes the application of in silico tools to predict the physico-chemical characters of CYP1A protein from the catfish, Clarias gariepinus.

Cytochrome P450 1A1 influences obesity‐induced pulmonary hypertension

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 9, Page 1824-1844, May 2026.
Background and Purpose The contribution of obesity to pulmonary arterial hypertension (PAH) pathophysiology remains poorly understood. Adipose tissue synthesises estrogens via cytochrome P450 (CYP) 19A1 (aromatase), whereas circulating estrogens are metabolised in the lung by CYP1A1.

Cytochromes P450 : from model compounds towards artificial hemoproteins [PDF]

open access: yes, 2007
Cytochromes P450 are heme-thiolate proteins abundant in nature. These monooxygenases catalyse a variety of reactions including alkene epoxixation, N-, O-, and S-dealkylation, C-C bond cleavage and hydrocarbon hydroxylation.

The Anticancer Drug Ellipticine Induces Cytochromes P450 1A1, 1A2 and 3A, Cytochrome b5 and NADPH:Cytochrome P450 Oxidoreductase in Rat Liver, Kidney and Lung

open access: yesInternational Journal of Electrochemical Science, 2013
The antineoplastic alkaloid ellipticine is a prodrug, the pharmacological efficiency of which is dependent on its cytochrome P450 (CYP)- and/or peroxidase-mediated activation in target tissues.
