Project description:This SuperSeries is composed of the following subset Series: GSE16733: Analysis of Gene Expression in Tissues of Two Turmeric Varieties at Different Developmental Stages GSE16734: Analysis of Gene Expression in Ginger Tissues at Different Developmental Stages Refer to individual Series
Project description:We developped a new oligo microarray platform to analyse flax transcriptome. Here, we validated this microarray on several tissues of flax, at different developmental stages.
Project description:mRNA expression profiles in the placenta tissues from different developmental stages in mice were analyzed by Arraystar Mouse LncRNA Microarray V3.0.
Project description:Two varieties of turmeric, FMO (Fat Mild Orange) and TYA (Thin Yellow Aromatic) were compared. Rhizomes were harvested 3, 5, and 7 months after planting, roots were harvested at 7 months, and leaves were harvested at 7 months. Plants were grown under controlled conditions in the greenhouse. We used an interwoven loop design for hybridizations. There are two interwoven loops included in this experiment, one for rhizome samples from the different developmental stages, and a second for leaf and root 7 month old samples compared to 7 month old rhizome samples. The two loops were connected at the 7 month old rhizome samples.
Project description:Rhizome, root and leaf of Yellow ginger were compared in this study. Rhizomes from 2, 3, 4, 6, and 7 month old plants (after planting) were compared to each other and to root from 2 and 7 month plants and leaves from 2 and 7 month old plants. Plants were grown under controlled conditions in the greenhouse. We used an interwoven loop design for hybridizations. There are two interwoven loops included in this experiment: one for rhizome developmental stages (2, 3, 4, 6, and 7 months old), the other one for all tissues of 2 and 7 month old plants. These interwoven designs are connected at the 2 month old and 7 month old rhizome samples.
Project description:Colitis is the common pathological lesion of inflammatory bowel diseases, the major chronic inflammatory diseases of intestinal tracts in humans. In this study, we investigated the therapeutic effects of ginger extract and its component zingerone in mice with 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis. Mice were administered with TNBS and/or various amounts of ginger and zingerone by an intrarectal route. The severity of colitis was evaluated by colonic weight/length ratio, macroscopic lesion, and histological examination. The mechanisms of ginger and zingerone were further elucidated by DNA microarray, ex vivo imaging, and immunohistochemical staining. Our data showed that treatment with ginger extract and zingerone ameliorated TNBS-induced colonic inflammation and injury in a dose-dependent manner. Pathway analysis of ginger- and zingerone-regulated gene expression profiles showed that ginger and zingerone significantly regulated cytokine-related pathways. Network analysis showed that nuclear factor-κB (NF-κB) and interleukin-1β (IL-1β) were key molecules involved in the expression of ginger- and zingerone-affected genes. Ex vivo imaging and immunohistochemical staining further verified that ginger and zingerone suppressed TNBS-induced NF-κB activation and decreased the NF-κB and IL-1β protein levels in the colon. In conclusion, our data showed that ginger improved the TNBS-induced colitis in mice via modulation of NF-κB activity and IL-1β signaling pathway. Moreover, zingerone might be the active component of ginger responsible for the amelioration of colitis induced by TNBS.
