Project description:Verteporfin (trade name Visudyne) is a medication used as a photosensitizer for photodynamic therapy to eliminate the abnormal blood vessels in the eye associated with conditions such as the wet form of macular degeneration. Verteporfin accumulates in these abnormal blood vessels and, when stimulated by nonthermal red light with a wavelength of 689 nm[1] in the presence of oxygen, produces highly reactive short-lived singlet oxygen and other reactive oxygen radicals, resulting in local damage to the endothelium and blockage of the vessels. Recently, it was reported that VP has chemotherapeutic effect in cancer. To identify the gene expression profile in gastric cancer cells by VP, we performed microarray.
Project description:Verteporfin (VP) inhibts colon cancer growth in vivo and in cell lines by inducing high molecular weight oligomerization of proteins. The antitumor effect of VP is independent of its YAP inhibitor activity. Tumor hypoxia contributes partly to antitumor effect of VP by impairing clearance of VP-induced high molecular weight aggregates.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
Project description:Aims:This study used cell line models and patient datasets to investigate the role of YAP1 in B- ALL. Methods: We used RNA-Seq to compare the gene expression levels of the Hippo pathway-related molecules before and after verteporfin (VP) treatment to identify important Hippo pathway-related genes in the NALM6 cell line. Results:we identified a total of 2002 differentially expressed genes in VP and DMSO treatment groups (FC ≥ 1.5, p ≤ 0.05), including 1042 upregulated and 960 downregulated genes, of which 146 were associated with the Hippo signaling pathway. Further screening resulted in 29 identified genes comprising 12 upregulated and 17 downregulated genes, which were associated with VP-treated NALM6 cells. Conclusion:Pre- and post-VP treatment, the upstream gene LATS1 was upregulated, and its overexpression increased YAP1 Ser127 site phosphorylation further studies.
