background: the hepatic secretion of apolipoprotein b (apob), containing lipoproteins, is known to be regulated by insulin, and the overproduction of these atherogenic lipoproteins occurs in insulin-resistant states. protein tyrosine phosphatase 1b (ptp-1b) is a key regulator of hepatic insulin signaling and is also upregulated in insulin resistance. we aimed to investigate the role of ptp-1b i...

urokinase might play a role in the formation of kidney stones. this study was done to determine the association between +4065 t/c polymorphism at the 3′-untranslated region of urokinase gene and calcium kidney stones. this case-control study was carried out on 70 cases with a history of calcium kidney stones and 70 controls from the baqiyatallah hospital of tehran in 2013. the study of polymorp...

It has been hypothesized that both the 3'-untranslated region (3'UTR) and the 5'-untranslated region (5'UTR) of the ornithine decarboxylase (ODC) mRNA influence the expression of the ODC protein. Here, we use luciferase expression constructs to examine the influence of both UTRs in keratinocyte derived cell lines. The ODC 5'UTR or 3'UTR was cloned into the pGL3 control vector upstream or downst...

The presence of a localization signal in the 3'-untranslated region of c-fos mRNA was investigated by in situ hybridization and cell fractionation techniques. Cells were transfected with chimeric gene constructs in which the beta-globin coding region was used as a reporter and linked to either its own 3'-untranslated region, the c-fos 3'-untranslated region, or the c-fos 3'-untranslated region ...

Molecular structure of a gene, ZmSTPK1, encoding a serine/threonine protein kinase in maize was analyzed by bioinformatic tool and its expression pattern was studied under chemical biological fertilizers. Bioinformatic analysis cleared that ZmSTPK1 is located on chromosome 10, from position 141015332 to 141017582. The full genomic sequence of the gene is 2251 bp in length and includes 2 exons. ...
