Project description:We investigated the antitumoral effect of verteporfin in YAP/AKT hydrodynamic tail vein injected murine models and we analyzed the correlative change of immune cell profile and stemness with the treatment of verteporfin by using flow cytometry and single-cell RNA sequencing
Project description:Together with TEAD4 the Hippo pathway effector YAP stimulates chromosomal instability. Verteporfin is known to disrupt the physical YAP/TEAD interaction and tehrefore might prevent from chromosomal instability in liver cancer. Immortalized HCC cell line hepG2 is treated with Verteporfin for 24 hours.
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: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.
