2009 journal article

Regulation of iron metabolism-related genes in diethylnitrosamine-induced mouse liver tumors

TOXICOLOGY LETTERS, 184(3), 151–158.

By: P. Youn*, S. Kim*, J. Ahn *, Y. Kim n, J. Park * & D. Ryu *

author keywords: Mouse; Liver tumors; Iron metabolism; Ceruloplasmin; DMT1 IRE(+)
MeSH headings : Adenoma, Liver Cell / chemically induced; Adenoma, Liver Cell / genetics; Adenoma, Liver Cell / metabolism; Animals; Antimicrobial Cationic Peptides / genetics; Antimicrobial Cationic Peptides / metabolism; Cation Transport Proteins / genetics; Cation Transport Proteins / metabolism; Ceruloplasmin / genetics; Ceruloplasmin / metabolism; Copper / metabolism; Diethylnitrosamine; Ferritins / genetics; Ferritins / metabolism; Gene Expression Regulation, Neoplastic; Hepcidins; Immunoblotting; Injections, Subcutaneous; Iron / blood; Iron / metabolism; Iron-Dextran Complex / administration & dosage; Liver Neoplasms, Experimental / chemically induced; Liver Neoplasms, Experimental / genetics; Liver Neoplasms, Experimental / metabolism; Male; Mice; Mice, Inbred C3H; RNA, Messenger / metabolism; Reverse Transcriptase Polymerase Chain Reaction; Transferrin / metabolism
topics (OpenAlex): Iron Metabolism and Disorders; Hemoglobinopathies and Related Disorders; Trace Elements in Health
TL;DR: It is suggested that diethylnitrosamine-induced liver adenoma-bearing mice have abnormal iron metabolism and that dysregulation of iron metabolism-related genes contributes to iron deficiency in the adenomas. (via Semantic Scholar)

1999 journal article

Constitutive expression and induction of CYP1B1 mRNA in the mouse

JOURNAL OF BIOCHEMICAL AND MOLECULAR TOXICOLOGY, 13(5), 249–251.

By: D. Ryu n & E. Hodgson n

topics (OpenAlex): Pharmacogenetics and Drug Metabolism; Drug Transport and Resistance Mechanisms; Drug-Induced Hepatotoxicity and Protection
TL;DR: The induction of CYP1B1 mRNA by PBO or ACN was higher in DBA/2 (Ahrd) than in C57BL/6 (Ahrb−1) mice, while 3‐methylcholanthrene induced CYP2B1 more in C 57BL/ 6 than in Dba/2 mice, suggesting that CYP 1B1 may also be induced by more than one mechanism. (via Semantic Scholar)

1997 journal article

Regulation of hepatic CYP1A isozymes by piperonyl butoxide and acenaphthylene in the mouse

CHEMICO-BIOLOGICAL INTERACTIONS, 105(1), 53–63.

By: D. Ryu n, P. Levi n & E. Hodgson n

author keywords: piperonyl butoxide; acenaphthylene; CYP1A1; CYP1A2; Ah receptor; C57BL/6; DBA/2; Ah receptor knockout (AHR(-/-)) mouse
MeSH headings : Acenaphthenes / pharmacology; Animals; Blotting, Northern; Blotting, Western; Cycloheximide / pharmacology; Cytochrome P-450 CYP1A1 / genetics; Cytochrome P-450 CYP1A2 / genetics; Cytochrome P-450 Enzyme System / genetics; Gene Expression Regulation, Enzymologic; Immunohistochemistry; Isoenzymes / genetics; Liver / enzymology; Male; Mice; Mice, Inbred C57BL; Mice, Inbred DBA; Piperonyl Butoxide / pharmacology; Polychlorinated Dibenzodioxins / pharmacology; Polymerase Chain Reaction / methods; RNA, Heterogeneous Nuclear / analysis; RNA-Directed DNA Polymerase; Teratogens / pharmacology
topics (OpenAlex): Pharmacogenetics and Drug Metabolism; Drug Transport and Resistance Mechanisms; Toxic Organic Pollutants Impact
TL;DR: The results suggest that PBO, but not ACN, induces CYP1A1 through a weak activation of AHR, and it is assumed that the transcriptional induction of CYP 1A2 by PBO and ACN is AHR-independent. (via Semantic Scholar)

1997 article

Regulation of mouse liver flavin-containing monooxygenases 1 and 3 by sex steroids

Falls, J. G., Ryu, D. Y., Cao, Y., Levi, P. E., & Hodgson, E. (1997, June 15). ARCHIVES OF BIOCHEMISTRY AND BIOPHYSICS, Vol. 342, pp. 212–223.

By: J. Falls n, D. Ryu n, Y. Cao n, P. Levi n & E. Hodgson n

author keywords: flavin-containing monooxygenases; FM01; FM03; FM05; FMO expression; hormonal regulation; testosterone; 17 beta-estradiol; progesterone
MeSH headings : Animals; Blotting, Western; Castration; Estradiol / blood; Estradiol / pharmacology; Female; Gene Expression Regulation, Enzymologic; Isoenzymes / metabolism; Liver / drug effects; Liver / enzymology; Male; Mice; Mice, Inbred Strains; Microsomes, Liver / metabolism; Organ Size / drug effects; Ovariectomy; Oxygenases / metabolism; Progesterone / blood; Progesterone / pharmacology; RNA, Messenger / metabolism; Seminal Vesicles / drug effects; Testosterone / blood; Testosterone / pharmacology; Uterus / drug effects
topics (OpenAlex): Effects and risks of endocrine disrupting chemicals; Estrogen and related hormone effects; Neuroscience and Neuropharmacology Research
TL;DR: In males and females, F MO5 levels were unaffected by gonadectomy or hormone administration, thus indicating a sex hormone-independent mechanism of regulation for this isoform, and Interestingly, FMO1 protein levels were increased in sexually intact males following treatment with 17 beta-estradiol; however, only a slight increase in FMO3 protein level was observed.
