Project description:Purpose:The red coloration of apple (Malus × domestica Borkh.) is due to the accumulation of anthocyanins in the fruit peel. Light is essential for anthocyanin biosynthesis in apple.Apple peel can quickly turn red under light conditions after unbagging. Therefore, the implementation of transcriptome sequencing to find genes that promote anthocyanin accumulation in response to light signals is necessary to clarify the mechanism of light-induced anthocyanin accumulation in apple peel.
Project description:In order to understand the role of phloems of apple dwarfing rootstocks,and investigated the expression differences of dwarfing and vigorous apple stocks in the bud break stage, The phloem tissue at bud break stage(0 DABB(days after buds break) of three apple rootstocks including A1d（a partial GA insensitive mutant of Malus hupehensis ),WT Malus hupehensis and were QZ1(a hybrid of Malus hupensis and a Cylindrical apple variety) were sampled and underwent RNA-Seq analysis.
Project description:Scope: Anthocyanins from diet were found to have therapeutic potential for various cancers including colorectal cancer (CRC). Given the diverse forms of anthocyanins, it is unclear whether different types of anthocyanins share common pathways in regulating intestinal cell function. This study aims to investigate the core gene pathways modulated by anthocyanins in intestinal cells, and to identify potential compounds with similar therapeutic effects.Methods and results: Three different forms anthocyanins were used to treat CRC cells at different concentrations and time points, and growth inhibition was observed in all anthocyanins, with varying patterns. RNA-seq analysis showed that the regulatory-pathways of anthocyanins with different structures were different, and the time factor had a greater effect. Time-series analysis of regulatory-genes shared by different concentrations and structures of anthocyanins was performed. By overlapping with public PPAR target gene set, a core gene set across three types of anthocyanins was identified and used in Connectivity Map (CMap) analysis to screen for compounds. The repositioned drug candidates included known anti-cancer drugs that have effects of transcriptome interventions similar to anthocyanins.Conclusion: These findings provide new insights into the mechanisms underlying the anti-CRC effects of anthocyanins and may facilitate the development of novel therapeutic agents for CRC.
Project description:We did transcription profiling on the effect of rlm1 deletion, gene involved in cell wall stress response Keywords: cell wall stress response
Project description:We performed total proteome and phosphoproteome analysis to characterize the role of non-mitotic kinase activity of CDK1 in insulin signaling through pharmacological inhibition and translational repression via siRNA-based knockdown. Specifically, cultured myotubes were treated with RO-3306, a selective ATP competitive inhibitor to inhibit CDK1 activity, or transfected with a CDK1 targeting siRNA pool to decrease CDK1 expression.
Project description:We did transcription profiling on the effect of rlm1 (MAPK Slt2 transcription factor) deletion and swi3 (component of SWI/SNF complex involved in chromatin remodeling) deletion in genes involved in cell wall stress (Congo Red) response.
