PURPOSE To evaluate the effect of Lamium album extract on human corneal epithelial cells (10.014 pRSV-T cell line) cultured in vitro. METHODS Normal human corneal epithelial cells were incubated with ethanol, ethyl acetate and heptane extracts from Lamium album. Their effect on cells was evaluated by neutral red (NR) uptake and MTT assays for cytotoxicity, ELISA for immunomodulation, Griess m...

background: linum album, a herbaceous and medicinal plant, has been shown to accumulate anti-tumor podophyllotoxin (ptox) and related lignans. objective: in this study, we have verified the time-course of cell growth, lignan production in cells treated with chitosan and chitin oligomers. to study mechanism of chitosan and chitin oligomers action, expression of phenylalanine ammonio-lyase (pal),...

Protein tyrosine phosphatases (PTPs) are central players in many biological processes. In this issue, Barr et al. (2009) analyze 22 different PTP structures to define their common and unique features. This effort provides key insights into the regulation of PTP activity that could lead to the development of new therapeutics.
