“Genetic based reporters have distinct
advantages over classical immunocytochemical techniques for probing cellular functions. Most importantly, they enable dynamic real-time visualization and quantification of cellular processes in living cells and tissue. This study was conducted to generate a genetic based reporter to label cells that transitioned from the G(0) to G(1)/S phases of the cell cycle, hypothesizing that the proximal promoter of the Ki67 (Ki67p) gene, a commonly used cytology marker induced during this transition, would contain the suitable regulatory elements to drive marker gene expression. This study
reports the cloning and characterization of the 1.5 kb proximal promoter (Ki67p) of the human Ki67 gene. Ki67p driven GFP expression colocalizes in cells with endogenous Ki67 expression and is correlated with cells transitioning through S/G(2)/M phases of the cell cycle. Treatment Ki67p-GFP expressing HT1080 cells with mitomycin C, an antineoplastic agent, induces P21 and P27 expression, G(1)/S/G(2)M block and attenuates Ki67p activity. Attenuation of the Ki67p also occurs during cell-density induced check details cell cycle arrest. Taken together, these results indicate that the Ki67p can be used to identify proliferating subpopulations
of live cells in intact complex three-dimensional cellular aggregates, such as embryoid bodies, thus providing some unique advantages over conventional immunohistochemical approaches. (C) 2010 International Society for Advancement of Cytometry”
“Objective: To determine the absolute bioavailability of naloxone from oral doses ranging from 5 mg to 120 mg. Materials AZD8186 in vivo and methods: In this open-label study, 28 healthy subjects received naloxone 1 mg (0.4 mg/ml) as an intravenous infusion (reference treatment), and the following oral doses as prolonged release (PR) naloxone tablets: 5 mg, 20 mg, 40 mg, 80 mg and 120 mg. The pharmacokinetic characteristics of 40 mg administered per rectum were also investigated. Each subject received five of the seven treatments as single doses with a 7 day washout between doses. Pharmacokinetic blood sampling and safety monitoring were performed for 24 h after the intravenous dose, and 72 h after the oral and rectal doses. Results: The mean absolute bioavailability of naloxone from the orally administered PR tablets was very low, ranging from 0.9% for the 5 mg dose to 2% for the 40, 80 and 120 mg doses, based on AUC(t) values. The pharmacokinetics of naloxone were linear across the range of oral doses.
