Project description:Dental follicle is a loose connective tissue that surrounds the developing tooth. Dental follicle cells (DFCs) have a promising potential for tissue engineering applications including periodontal and bone regeneration. However, little is known about the molecular mechanisms underlying osteogenic differentiation. In a previous study we detected that more than 35 % of genes that are regulated during osteogenic differentiation of DFCs have promoter binding sites for the transcription factors TP53 and SP1. However, the role of these transcription factors in dental stem cells is still unknown. We hypothesize that both factors influence the processes of cell proliferation and differentiation in dental stem cells. Therefore, we transiently transfected DFCs and dental pulp stem cells (SHED; Stem cells from human exfoliated decidiuous teeth) with expression vectors for these transcription factors. After overexpression of SP1 and TP53, SP1 influenced cell proliferation and TP53 osteogenic differentiation in both dental cell types. The effects on cell proliferation and differentiation were less pronounced after siRNA mediated silencing of TP53 and SP1. This indicates that the effects we observed after TP53 and SP1 overexpression are indirect and subject of complex regulation. Interestingly, upregulated biological processes in DFCs after TP53-overexpression resemble the downregulated biological processes in SHED after SP1-overexpression. Here, regulated processes are involved in cell motility, wound healing and programmed cell death. In conclusion, our study demonstrates that SP1 and TP53 influence cell proliferation and differentiation and similar biological processes in both SHED and DFCs. Total RNAs were isolated from dental follicle cells after 48 hours of transfection with a TP53 expressions plasmid, a SP1 expressions plasmid and for control with an empty vector.

Project description:PANC-1Tet/ZIC2 and PANC-1Tet/empty were established from human pancreatic cancer cell line PANC-1. PANC-1Tet/ZIC2 cells express FLAG-tagged human ZIC2 on the withdrawal of DOX. On the other hand, PANC-1Tet/empty was transfected an empty vector for the control experiment. To identify ZIC2 target genes, total RNAs were purified from the cells before and 48 hours after the DOX withdrawal. Gene expression profiles were analyzed by AGILENT human 4x44k cDNA microarray. As well as ZIC2-inducible system, we performed ZIC2-knockdown experiments in PANC-1 human pancreatic cancer cells. After 96 hours transfection of siRNAs for ZIC2 and its control, total RNAs were purified and gene expression profiles were analyzed by AGILENT human 4x44k cDNA microarray.

Project description:We have found through previous experiments that circCUL2 acts as a key regulator of cancer-associated fibroblasts activation. To determine how circCUL2 exert its function, we performed mRNA sequencing of normal fibroblasts (NFs) and circCUL2-transduced NFs. 48 hours after transfection, RNA was isolated and sent for total RNA sequencing. Differential gene expression between circCUL2-overexpression and empty vector revealed enrichment for several inflammation pathways implicating involvement of these pathways in inflammatory cancer-associated fibroblasts activation.

Project description:CCE mESCs were transfected with either empty pCAGGS vector or HA-MEK5DD (S311D T315D) construct for 48 hours. 24 hours prior to lysis, mESCs were either treated with 10uM AX15836 or DMSO control, and transfected mESCs selected with puromycin. Conditions were performed in triplicate.
