Targeting activating mutations of EZH2 leads to potent cell growth inhibition in human melanoma by derepression of tumor suppressor genes
The epigenetic modifier EZH2 is part of the polycomb repressive complex that suppresses gene expression via histone methylation. Activating mutations in EZH2 are found in a subset of melanoma that contributes to disease progression by inactivating tumor suppressor genes. In this study we have targeted EZH2 with a specific inhibitor (GSK126) or depleted EZH2 protein by stable shRNA knockdown. We...
متن کاملCryptolepine, a Plant Alkaloid, Inhibits the Growth of Non-Melanoma Skin Cancer Cells through Inhibition of Topoisomerase and Induction of DNA Damage.
Topoisomerases have been shown to have roles in cancer progression. Here, we have examined the effect of cryptolepine, a plant alkaloid, on the growth of human non-melanoma skin cancer cells (NMSCC) and underlying mechanism of action. For this purpose SCC-13 and A431 cell lines were used as an in vitro model. Our study reveals that SCC-13 and A431 cells express higher levels as well as activity...
متن کاملInhibition of melanoma tumor growth in vivo by survivin targeting.
A role of apoptosis (programmed cell death) in tumor formation and growth was investigated by targeting the apoptosis inhibitor survivin in vivo. Expression of a phosphorylation-defective survivin mutant (Thr(34)-->Ala) triggered apoptosis in several human melanoma cell lines and enhanced cell death induced by the chemotherapeutic drug cisplatin in vitro. Conditional expression of survivin Thr(...
متن کاملexpression of pml tumor suppressor in a431 cells reduces cellular growth by inhibiting the egfr expression
our previous studies showed that the promyelocytic leukemia protein, pml, functions as acellular and growth suppressor. transient expression of pml was also found to repress the activity of theepidermal growth factor receptor (egfr) gene promoter. in this study, we have examined the effects ofpml on a431 cells, which express a high level of egfr protein. the pml gene was introduced into thecell...
متن کاملCoordinated changes in mitochondrial function and biogenesis in healthy and diseased human skeletal muscle.
We examined the transcriptional signaling cascade involved in the changes of mitochondrial biogenesis and mitochondrial function of skeletal muscle and of the exercise capacity of humans in response to long-term physical activity and chronic heart failure (CHF). Biopsy samples of vastus lateralis muscle were obtained from 18 healthy subjects with different fitness levels (assessed by maximal ox...
