Project description:In order to study the role of piR_019914 in C28/I2 cells, we established piR_019914_mimics to overexpress piR_019914 in C28/I2 cells We then performed gene expression profiling analysis using data obtained from RNA-seq of piR_019914 overexpression C28/I2 cells and mimics_NC C28/I2 cells.
Project description:We report here the overexpression of DPP4 in C28/I2 chondrocyte cells to investigate the changes induced by elevated levels of this gene. DPP4 is known as a marker of cellular senescence, yet its regulatory mechanisms remain unclear. In this study, we utilized the C28/I2 cell line to overexpress DPP4 and analyzed the resultant effects on gene expression and cellular behavior. Our findings reveal that DPP4 overexpression influences several pathways associated with chondrocyte function and senescence. Specifically, we observed alterations in pathways related to extracellular matrix organization, inflammatory response, and cellular aging. These results suggest that DPP4 plays a significant role in the modulation of chondrocyte senescence and may provide new insights into the mechanisms of cellular aging. Taken together, our data provide a molecular framework for understanding how DPP4 overexpression impacts chondrocyte physiology and offers potential targets for therapeutic intervention in age-related cartilage diseases.
Project description:3-D suspension culture differs considerably from monolayer culture in regards to cell architecture, cell to cell contact, and cell to matrix interactions. These factors play a regulatory role in epithelial stem cell homeostasis and influence epidermal stem cells on their decision to remain quiescent or to activate self-renewal. We used microarrays to determine the global programme of gene expression underlying spheroid ring formation and identified distinct gene programs involved in this process.
Project description:To examine the effects of DPP4 overexpression and its modulation by 4,5-Dicaffeoylquinic acid on chondrocytes, we established C28/I2 cell lines with DPP4 overexpression (DPP4OE), control empty vector (OENC), and DPP4OE treated with 4,5-Dicaffeoylquinic acid. Gene expression profiling analysis was performed using RNA sequencing (RNA-seq) with biological replicates to investigate the global transcriptomic changes associated with these conditions.
Project description:Recently, it has been proposed to employ three-dimensional cultivation of cell in spheroids that contributes more proper physiological conditions in matrix extracellular space architecture and cell morphology accompanied by appropriate intracellular biomechanical organization of cytoskeleton and energy generation apparatus adaptation. In this research we presented the data of proteome survey for cells growing in monolayer and in spheroids that were induced in myogenic way of differentiation and reached terminal stage in seven days. Semi-quantitative profiling of the dynamic changes in proteins abundance depicted strict advantage of spheroid manner cultivation in contrast to monolayer. Cells cultured in spheroid were significantly enriched in proteins of mitochondria biogenesis, respiratory chain proteins, extracellular proteins and cytoskeleton. Most of signal transducers involved in active proliferation and early stages of differentiation were inhibited in spheroid cultures unlike monolayer. The obtained data were broadly consistent with known molecular mechanisms of myogenesis in transcripts level and reflected strong advantage of spheroid cultivation conditions.
