Dermatol Ther (Heidelb). 2020 Apr;10(2):263-271. doi: 10.1007/s13555-020-00360-4. Epub 2020 Feb 15.

INTRODUCTION: Azathioprine is a synthetic purine analogue derived from 6-mercaptopurine which acts by disrupting nucleic acid synthesis and interfering with T cell activation. It is effective in dermatology diseases related to the immune system. However, its side effects, including...

The effect of various agents on the activation of succinate dehydrogenase in cauliflower (Brassica oleracea) and mung bean (Phaseolus aureus) mitochondria and in sonicated particles has been investigated. Reduced coenzyme Q(10), inosine diphosphate, inosine triphosphate, acid pH, and anions...

Elevated Levels of DNA Strand Breaks Induced by a Base Analog in the Human Cell Line with the P32T ITPA Variant.

Journal of nucleic acids

Waisertreiger IS, Menezes MR, Randazzo J, Pavlov YI.
PMID: 20936128
J Nucleic Acids. 2010 Sep 26;2010. doi: 10.4061/2010/872180.

Base analogs are powerful antimetabolites and dangerous mutagens generated endogenously by oxidative stress, inflammation, and aberrant nucleotide biosynthesis. Human inosine triphosphate pyrophosphatase (ITPA) hydrolyzes triphosphates of noncanonical purine bases (i.e., ITP, dITP, XTP, dXTP, or their mimic: 6-hydroxyaminopurine (HAP)...

Thiopurine drugs are the most common drugs used to maintain clinical remission in inflammatory bowel disease (IBD). Three single-nucleotide polymorphisms (SNPs), TPMT A719G (rs1142345), inosine triphosphate pyrophosphatase (ITPase) C94A (rs1127354) and multidrug resistance protein 4 MRP4 G2269A (rs3765534), have...

An index to predict ribavirin-induced anemia in asian patients with chronic genotype 1 hepatitis C.

Hepatitis monthly

Hepat Mon. 2015 Mar 20;15(3):e27148. doi: 10.5812/hepatmon.27148. eCollection 2015 Mar.

BACKGROUND: Single-nucleotide polymorphisms (SNP) in the inosine triphosphate pyrophosphatase (ITPA) gene correlate with ribavirin (RBV)-induced anemia in patients with chronic hepatitis C (CHC) receiving combination therapy. Managing anemia is an early priority in the treatment process.OBJECTIVES: The aim was...

Efficacy of splenectomy in preventing anemia in patients with recurrent hepatitis C following liver transplantation is not dependent on inosine triphosphate pyrophosphatase genotype.

AIM:   A genetic polymorphism of inosine triphosphate pyrophosphatase (ITPA) has been associated with pegylated-interferon/ribavirin (PEG-IFN/RBV)-induced anemia in chronic hepatitis C patients. However, correlation of the genetic variant with anemia following liver transplantation has not been determined.METHODS:   Sixty-three hepatitis C...
