INTRODUCTION: Several RFLFs have been described in the human phosphoglycerate kinase 1 (PGK1) gene in Xql3. Whereas the PstI polymorphism as detected with PGK1 cDNA (Hutz et al.) was complicated by multiple X-linked and autosomal constant bands, only two bands are seen with a fourth-intron genomic probe. We have compared this PstI RFLP to the 5' Bgll RFLP detected by pSPT-PGK (Vogelstein et al....

Using polymerase chain reaction, we detected the varicella-zoster virus genome in the vitreous humor of two patients with clinically diagnosed acute retinal necrosis. One of the two cases was thought to be caused by infection with a varicella-zoster virus lacking a PstI cleavage site. We could not find any clinical differences between the two substrains. The presence of a PstI cleavage site on ...

The aim of this study was to explore the cytochrome P450 2E1 (CYP2E1) RsaI/PstI polymorphism and risk of esophageal cancer (EC) in mainland Chinese populations. A systematic search of PubMed, EMBASE, Web of Science, CBM, CNKI and VIP databases for publications on the CYP2E1 RsaI/PstI polymorphism and risk of EC was performed. and the genotype data were analyzed in a meta-analysis. Odds ratios (...

Polymorphism. PstI restriction fragment length polymorphism (RFLP) in the ovine Aconitase 2 (AC02) gene. Source and Description of Probe. The probe is a .9kb AC02 cDNA from a porcine myocardial hgt 10 library (Zheng et al., 19901, cloned into the EcoRI site of pUC118. The insert was gel-purified and radiolabeled with [ c Y ~ ~ P I ~ C T P by the random primer method to specific activity > lo9 d...

Monkey B-lymphotropic papovavirus (LPV) replicates only in B-lymphoblastoid cells, whereas the LPV mutant 76 (LPV-76) can grow in either B- or T-lymphoblastoid cells. The nucleotide sequence of the wild-type LPV PstI B segment was compared with that of LPV-76 PstI-B, within which the mutation responsible for the extended host range had been located. The VP-1 coding region of LPV-76 was found to...

INTRODUCTION In mammalian pancreatic cells, the pancreatic secretory trypsin inhibitor (PSTI) prevents the premature activation of digestive enzymes and thus plays an important role in a protective mechanism against tissue destruction by autophagy, a process which may ultimately cause diseases such as pancreatitis and pancreatic cancer. Insects, however, lack a pancreas and so far no PSTI-like ...

BACKGROUND Cytochrome P450 2E1 (CYP2E1), an ethanol-inducible enzyme, has been shown to metabolically activate various carcinogens, which is critical for the development and progression of cancers. It has demonstrated that CYP2E1 polymorphisms alter the transcriptional activity of the gene. However, studies on the association between CYP2E1 polymorphisms (PstI/RsaI or DraI) and gastric cancer h...

Source and Description: The DNA marker pKP 1.65, is a single copy probe for the D4S43 locus. The 1.7 kb PstI fragment reveals a VNTR (1). Recently, the detection of the VNTR by PCR, after sequencing the adjacent 1269 bp PstI fragment was described (2). In order to construct primers for PCR we have sequenced the 1652 bp PstI fragment of pKP 1.65. A guanosine rich sequence in the last third of th...

A mutant (MPA100) strain of Leishmania donovania was generated from a wild type (D1700) population by virtue of its ability to survive the selective pressure of gradually increasing concentrations of mycophenolic acid (MPA), an inhibitor of IMP dehydrogenase (IMPDH) activity. Comparative growth experiments revealed that the MPA100 strain was 100-fold more resistant to MPA toxicity and cross-res...

Cytochrome P450IIE1 is responsible for the activation of carcinogenic N-nitrosamines, benzene, urethane, and other low-molecular-weight compounds. Restriction fragment length polymorphisms (PstI and RsaI restriction enzymes) have been identified in the cytochrome P450IIE1 transcription regulatory region that may affect expression. This study describes the PstI and RsaI polymorphisms in differen...
