Project description:Members of the Caryophyllaceae Juss. family possess anabolic, adaptogenic, radioprotective, antitumoral and hemorheological properties and have been used in medical practice for the treatment of various inflammatory disorders. Macrophages are key immune cells that coordinate the inflammatory reaction. To identify the effects of Silene sendtneri and Silene roemeri on macrophage activation, primary human macrophages were cultured with extracts of these plants .We used microarrays to determine the global expression pattern induced by the extracts in macrophages.
Project description:microRNA-150 (miR-150) is mainly expressed in the lymph nodes and spleen and is highly up-regulated during the development of mature T and B cells. To understand the signal-transduction network for 'effector or memory T cells' and 'mir-150' in naïve, effector, or memory CD8 T cells of mir-150 knockout and wild-type mice, we analyzed gene expression profiles by microarray. The genetic background of the cells used in this study is CD8 T cells from spleen of the 8 week-old male C57BL/6J mice (for female: WT-memory_2 & KO-memory_2).

Project description:Analyses of Heteropterys umbellata (Malpighiaceae) stems and leaves extracts. Plants were collected in two different Brazilian States (Sao Paulo and Minas Gerais). Dried plant material was extracted with EtOH80%. Positive ionization mode analyses. LC-MS/MS performed in a Shimadzu HPLC using a Phenomenex C18-Luna (250 mm x 4.6 mm, 5.0 um) column and an Amazon SL (Bruker Daltonics) mass spectrometer (ion trap) equipped with an ESI source. Auto MSn mode for exploratory analysis.

Project description:JAV1 functions as a negative regulator to control plant defense. Defense-related genes were highly induced in JAV1 RNAi plants compared to wild-type plants in response to wounding or jasmonate treatments. We used microarrays to detail the global programme of gene expression underlying JAV1 effects on expression of genes involving in defense response, lipid metabolism and regulating transcription. For the Affymetrix microarray assay with 100 uM MeJA treatment, 21-day-old seedlings grown in MS medium were treated with 100 μM MeJA for various time periods (0, 1, and 4 hours). For the Affymetrix microarray assay with wounding treatment, JAV1 RNAi line Ri17 versus wild-type was utilized after mechanical wounding for various time periods. Four rosette leaves from 21-day-old plants were crushed across the midrib with a forceps. About 30% of each leaf was damaged. Wounded leaves were harvested at various time periods (0, 0.5, and 1 hour) for RNA extraction. Control plants were untreated and leaves were harvested for RNA extraction.
