Acitretin : A Review of its Pharmacology and Therapeutic Use.

Drugs

Pilkington T, Brogden RN.
PMID: 28421560
Drugs. 1992 Apr;43(4):597-627. doi: 10.2165/00003495-199243040-00010.

SYNOPSIS: Acitretin (etretin), a second generation monoaromatic retinoid for use in the treatment of severe psoriasis and other dermatoses, is the major active metabolite of etretinate and possesses a similar therapeutic index; i.e. a similar ratio of clinical efficacy...

Simultaneous targeting of 5-LOX-COX and ODC block NNK-induced lung adenoma progression to adenocarcinoma in A/J mice.

American journal of cancer research

Kumar G, Patlolla JM, Madka V, Mohammed A, Li Q, Zhang Y, Biddick L, Singh A, Gillaspy A, Lightfoot S, Steele VE, Kopelovich L, Rao CV.
PMID: 27293987
Am J Cancer Res. 2016 May 01;6(5):894-909. eCollection 2016.

Lung cancer is the leading cause of cancer deaths worldwide. Targeting complementary pathways will achieve better treatment efficacy than a single agent high-dose strategy that could increase risk of side effects and tumor resistance. To target COX-2, 5-LOX, and...

Polyamines directly promote antizyme-mediated degradation of ornithine decarboxylase by the proteasome.

Microbial cell (Graz, Austria)

Beenukumar RR, Gödderz D, Palanimurugan R, Dohmen RJ.
PMID: 28357293
Microb Cell. 2015 May 20;2(6):197-207. doi: 10.15698/mic2015.06.206.

Ornithine decarboxylase (ODC), a ubiquitin-independent substrate of the proteasome, is a homodimeric protein with a rate-limiting function in polyamine biosynthesis. Polyamines regulate ODC levels by a feedback mechanism mediated by ODC antizyme (OAZ). Higher cellular polyamine levels trigger the...

Spermidine is protective against kidney ischemia and reperfusion injury through inhibiting DNA nitration and PARP1 activation.

Anatomy & cell biology

Kim J.
PMID: 29043098
Anat Cell Biol. 2017 Sep;50(3):200-206. doi: 10.5115/acb.2017.50.3.200. Epub 2017 Sep 20.

Kidney ischemia and reperfusion injury (IRI) is associated with a high mortality rate, which is attributed to tubular oxidative and nitrative stresses; however, an effective approach to limit IRI remains elusive. Spermidine, a naturally occurring polyamine, protects yeast cells...

Hyperhomocysteinemia, Suppressed Immunity, and Altered Oxidative Metabolism Caused by Pathogenic Microbes in Atherosclerosis and Dementia.

Frontiers in aging neuroscience

McCully KS.
PMID: 29056905
Front Aging Neurosci. 2017 Oct 06;9:324. doi: 10.3389/fnagi.2017.00324. eCollection 2017.

Many pathogenic microorganisms have been demonstrated in atherosclerotic plaques and in cerebral plaques in dementia. Hyperhomocysteinemia, which is a risk factor for atherosclerosis and dementia, is caused by dysregulation of methionine metabolism secondary to deficiency of the allosteric regulator,...

A comparison of RNA concentrations and ornithine decarboxylase activity in Atlantic salmon (Salmo salar) muscle tissue, with respect to specific growth rates and diel variations.

Fish physiology and biochemistry

Arndt SK, Benfey TJ, Cunjak RA.
PMID: 24197142
Fish Physiol Biochem. 1994 Dec;13(6):463-71. doi: 10.1007/BF00004329.

RNA concentrations and enzyme activities are often used as indices of recent growth in fish, but few studies have used both methods to assess the same fish. This study measured RNA concentrations and ornithine decarboxylase (ODC) activity in muscle...

Ornithine decarboxylase and ribosomal RNA synthesis during the stimulation of lymphocytes by phytohaemagglutinin.

FEBS letters

Kay JE, Cooke A.
PMID: 11945886
FEBS Lett. 1971 Jul 15;16(1):9-12. doi: 10.1016/0014-5793(71)80671-3.

Cessation of Long-term Alcohol Administration and Two-day Cycling of Exposure Respectively Promote and Inhibit Hepatocarcinogenesis in Rats.

Asian Pacific journal of cancer prevention : APJCP

Tanaka T, Hirota Y, Kuriyama M, Nishiguchi S, Otani S.
PMID: 12716308
Asian Pac J Cancer Prev. 2000;1(4):325-328.

The effects of different patterns of alcohol administration on hepatocarcinogenesis induced by diethylnitrosamine (DEN) in male Wistar rats were assessed using a modified Ito's medium-term bioassay system. Carcinogenic potential was scored by comparing numbers and areas of glutathione S...

Studies on ornithine decarboxylase activity in normal and T2-infected Escherichia coli.

FEBS letters

Bachrach U, Ben-Joseph M.
PMID: 11945817
FEBS Lett. 1971 Jun 02;15(1):75-77. doi: 10.1016/0014-5793(71)80082-0.

Polyamine depletion induces G1 and S phase arrest in human retinoblastoma Y79 cells.

Cancer cell international

Ueda A, Araie M, Kubota S.
PMID: 18208615
Cancer Cell Int. 2008 Jan 21;8:2. doi: 10.1186/1475-2867-8-2.

BACKGROUND: Polyamines and ornithine decarboxylase (ODC) are essential for cell proliferation. DL-alpha-difluoromethylornithine (DFMO), a synthetic inhibitor of ODC, induces G1 arrest through dephosphorylation of retinoblastoma protein (pRb). The effect of DFMO on cell growth of pRb deficient cells is...

Effects of a high soy protein diet on intestinal polyamines and ornithine decarboxylase activity in rats.

The Journal of nutritional biochemistry

Meziani K, Benamouzig R, Mahé S, Martin A, Bouras M, Rautureau J, Tomé D.
PMID: 15539316
J Nutr Biochem. 1999 Jul;10(7):405-10. doi: 10.1016/s0955-2863(99)00019-4.

This study was performed to determine whether intestinal luminal polyamine concentrations are affected by a high soy protein diet when compared with a high casein diet or a normoprotein casein diet. We also determined the effects of these diets,...

Ornithine decarboxylase, polyamines, and pyrrolizidine alkaloids in senecio and crotalaria.

Plant physiology

Birecka H, Birecki M, Cohen EJ, Bitonti AJ, McCann PP.
PMID: 16665870
Plant Physiol. 1988 Jan;86(1):224-30. doi: 10.1104/pp.86.1.224.

When tested for ornithine and arginine decarboxylases, pyrrolizidine alkaloid-bearing Senecio riddellii, S. longilobus (Compositae), and Crotalaria retusa (Leguminosae) plants exhibited only ornithine decarboxylase activity. This contrasts with previous studies of four species of pyrrolizidine alkaloid-bearing Heliotropium (Boraginaceae) in which...
