1. Laticifer proteins from Plumeria pudica inhibit the inflammatory and nociceptive responses by decreasing the action of inflammatory mediators and pro-inflammatory cytokines
AbstractSome publications have described the pharmacological properties of latices proteins. Thus, in the present study proteins from Plumeria pudica Jacq., Apocynaceae, latex were evaluated for anti-inflammatory and antinociceptive activities. Obtained data showed that an intraperitoneal administration of different doses of latex was able to reduce the paw

2. CaracterizaÃÃo bioquÃmica e atividade citotÃxica in vitro e antitumoral in vivo de proteÃnas do lÃtex de Calotropis procera / Biochemical characterization and cytotoxicity in vitro and antitumor activity in vivo of protein from the of latex Calotropis procera
O lÃtex de Calotropis procera foi descrito como uma fonte de proteÃnas farmacologicamente ativas como atividade antiinflamatÃria e analgÃsica. O presente trabalho avaliou a atividade citotÃxica in vitro das proteÃnas (PL) recuperadas do lÃtex da planta medicinal C. procera contra cÃlulas de cÃncer humano e a inibiÃÃo do crescimento do Sarcoma 180

3. Latex fluids are endowed with insect repellent activity not specifically related to their proteins or volatile substances
Latex is an endogenous milky fluid synthesized and accumulated under pressure in a network of laticifer cells. In this study, latices from five plant species were examined for deterrent effect on oviposition of two Coleoptera (Bruchidae) pests. The latex from Euphorbia tirucalli, Calotropis procera and Plumeria rubrae exhibited deterrent activity on oviposit

4. Anti-oxidative and proteolytic activities and protein profile of laticifer cells of Cryptostegia grandiflora, Plumeria rubra and Euphorbia tirucalli
In this study, proteins extracted from laticifer cells of three plants were examined by electrophoresis, mass spectrometry (MALDI-TOF) and characterized in respect of proteolytic, chitinolytic and anti-oxidative activities by means of zymography and colorimetric assays. Acidic proteins with molecular masses between 12.5 and 74.5 kDa predominated in laticifer

5. MÃltiplas proteÃnas estÃo envolvidas nas atividades antiinflamatÃria e antinociceptiva do lÃtex da planta medicinal Calotropis procera (AIT.) R. Br / Multiple proteins are involved in the anti-inflammatory and antinociceptive activities displayed by the latex of the medicinal plant Calotropis procera (Ait.) R. Br.
A planta Calotropis procera, pertencente à famÃlia Apocinaceae, tem como uma de suas principais caracterÃsticas a produÃÃo constitutiva de lÃtex. Este fluido à amplamente utilizado na medicina popular, principalmente da Ãndia, por apresentar diversas propriedades curativas. Na literatura, o produto da extraÃÃo do lÃtex Ãntegro com solvente aquoso

6. Potential of laticifer fluids for inhibiting Aedes aegypti larval development: evidence for the involvement of proteolytic activity
It has been shown previously that the laticifer fluid of Calotropis procera (Ait.) R.Br. is highly toxic to the egg hatching and larval development of Aedes aegypti L. In the present study, the larvicidal potential of other laticifer fluids obtained from Cryptostegia grandiflora R.Br., Plumeria rubra L. and Euphorbia tirucalli L. was evaluated. We attempted

7. Polyphenoloxidase Silencing Affects Latex Coagulation in Taraxacum Species1[W]
Latex is the milky sap that is found in many different plants. It is produced by specialized cells known as laticifers and can comprise a mixture of proteins, carbohydrates, oils, secondary metabolites, and rubber that may help to prevent herbivory and protect wound sites against infection. The wound-induced browning of latex suggests that it contains one or

8. Multicellular compartmentation of catharanthus roseus alkaloid biosynthesis predicts intercellular translocation of a pathway intermediate
In situ RNA hybridization and immunocytochemistry were used to establish the cellular distribution of monoterpenoid indole alkaloid biosynthesis in Madagascar periwinkle (Catharanthus roseus). Tryptophan decarboxylase (TDC) and strictosidine synthase (STR1), which are involved in the biosynthesis of the central intermediate strictosidine, and desacetoxyvindo

9. Molecular and Biochemical Analysis of a Madagascar Periwinkle Root-Specific Minovincinine-19-Hydroxy-O-Acetyltransferase1
The terminal steps in the biosynthesis of the monoterpenoid indole alkaloids vindoline and minovincinine are catalyzed by separate acetyl coenzyme A-dependent O-acetyltransferases in Madagascar periwinkle (Catharanthus roseus G. Don). Two genes were isolated that had 63% nucleic acid identity and whose deduced amino acid sequences were 78% identical. Ac
