15935074-3	2005	There are abnormalities in purine and pyrimidine nucleotide content in HPRT-deficient cells.	Pyrimidine Nucleotides	38-59	hypoxanthine guanine phosphoribosyl transferase	Mus musculus	71-75	
10037486-6	1999	In addition, the HGPRT-deficient astroglia were shown to contain lower cellular levels of ADP, ATP, and GTP, indicating that the accelerated de novo purine synthesis does not compensate adequately for the deficiency of salvage nucleotide synthesis, and higher level of UTP, probably due to enhanced de novo synthesis of pyrimidine nucleotides.	Pyrimidine Nucleotides	320-342	hypoxanthine guanine phosphoribosyl transferase	Mus musculus	17-22
