Cloned coding sequences for rat and human ornithine transcarbamylase (OTC) were obtained by screening a rat and a human cDNA library respectively with a synthetic oligonucleotide corresponding to 27 bases of the rat sequence. These clones, 1100 bp long for the rat clone and 1300 bp for the human, contain approximately 80% of the human OTC coding sequence.(More)
BACKGROUND Fine tuning of the Wnt/β-catenin signaling pathway is essential for the proper development and function of the liver. Aberrant activation of this pathway is observed in 20%-40% of hepatocellular carcinomas (HCC). Notum encodes a secreted Wnt deacylase that inhibits Wnt activity and thereby restricts the zone of activation of Wnt/β-catenin(More)
We have previously reported the epidermis-specific expression of the HIV-1 LTR in transgenic mice and its induction by UV-B rays. To dissect the underlying mechanism of the UV induction of the LTR in mice, we developed two approaches. We first demonstrated by gel mobility shift analysis, using mice epidermal extracts, that the NF-kappa B sites of the HIV-1(More)
