Project description:Recently, direct reprogramming between divergent lineages has been achieved by introducing cell-fate-determining transcription factors. This progress may provide alternative cell resources for drug discovery and regenerative medicine. However, the genetic manipulation may limit the future application of these approaches. In this study, we identified a novel small-molecule cocktail that directly converted fibroblasts into neuronal cell fate with a high yield up after 16-days of induction. After a further maturation stage, these chemically-induced neurons (CiNs) possessed neuron-specific expression patterns, generated action potentials and formed functional synapses. Gene expression profiling revealed the activation of neuronal specific genes in the early stage of small molecule treatment. Overall, our findings prove the principle of chemically-induced direct reprogramming of somatic cell fates across germ layers without genetic manipulation, and show that cell fate can be manipulated through disrupting initial cell program and activating target cell master genes with pure chemicals. Total of 15 samples were analyzed, including mouse fibroblasts, mouse cortical primary neurons and chemically-induced neurons by different duration of chemical induction (Day0, Day4, Day8, Day19) and different small-molecule cocktail (FICB, FICB-1)
Project description:The AP2/ERF domain transcription factor ABSCISIC ACID INSENSITIVE4 (ABI4) modulates diverse developmental and physiological processes by integrating multiple environmental factors and phytohormone signals in plants. To further investigate the molecular mechanism of ABI4 in plant development, we examined the global gene expression in the WT and abi4-1 plants using RNA sequencing.
Project description:The aim of this study was to determine the role of genes encoding polygalacturonases in strawberry fruit softening. To this purpose, several transgenic lines, cv. Chandler, were generated: plants with PG genes FaPG1 or FaPG2 downregulated, alone or in combination, by antisense transformation. Plants were grown in a confined greenhouse and fruits were harvested at the stage of full ripeness (100% of fruit surface red). The results obtained indicate that the silencing of these genes reduced fruit softening at similar level but there is not a sinergistic effect on fruit firmness.
