The hypothetical
see more invasion also significantly reduced the connectance of the web because the loss of 17 native trematode species eliminated many links.”
“Background: Plasminogen activator inhibitor-2 (PAI-2) is an enzyme inhibitor which is involved in various biological processes including cell differentiation, tissue regrowth and regeneration. Although PAI-2 has been originally isolated as an extracellular inhibitor of urokinase plasminogen activator (uPA), recent studies indicate that PAI-2 has other intracellular effects in keratinocyte, such as the component of cornified envelope.
Objective: The aim of this study is to investigate the expression and functional role of PAI-2 during the keratinocyte differentiation.
Methods: We transduced keratinocytes with adenovirus harboring the expression cassette for PAI-2, then examined the effect on keratinocytes differentiation.
Results: When cultured epidermal keratinocytes were treated with 1.2 mM calcium, PAI-2 expression was increased time-dependently at both mRNA and protein levels. The calcium-induced PAI-2 expression was abolished by treatment with p38 MARK inhibitor,
while overexpression of MKK6 led to the increase of PAI-2 expression. When PAI-2 was overexpressed by adenoviral transduction, the expression of keratinocyte differentiation markers such as involucrin, keratin 10 and loricrin was markedly increased. Concomitantly, overexpression of PAI-2 resulted in the retardation of cell growth, with the increase of Rb and p53.
Conclusion: These results suggest that PAI-2 has a role for promoting the differentiation of epidermal keratinocytes. selleck compound (C) 2010 Japanese Society for Investigative Dermatology. Published by Elsevier Ireland Ltd. All rights reserved.”
“An analytical method for the simultaneous determination of 16 types of structural amino acids in infant formula using an automated amino acid
analyzer was validated through tests of precision, accuracy and linearity. The automated analysis of the amino acids was performed on an ion-exchange packed column with a visible detector. The certificated reference material (CRM) 1546 from NIST was used as the test sample to determine the precision and accuracy of the analytical method. The regression analyses revealed good correlations [correlation Akt inhibitor coefficient (r(2))] that were greater than 0.99. The recovery values of the amino acids were ranged from 87.18 to 118.08%. The limits of detection and limits of quantification were less than 0.059 mg/100 g and less than 0.198 mg/100 g, respectively. The infra- and inter-day precisions were less than 14.62% in the CRM sample.”
