Silencing of a viral RNA silencing suppressor in transgenic plants

Journal of General Virology, 2002
High expression levels of the helper component proteinase (HCpro), a known virus suppressor of RNA silencing, were attained in Nicotiana benthamiana transformed with the HCpro cistron of Potato virus A (PVA, genus Potyvirus). No spontaneous silencing of the HCpro transgene was observed, in contrast to the PVA coat protein (CP)-encoding transgene in ...

SILAC-based phosphoproteomics reveals an inhibitory role of KSR1 in p53 transcriptional activity via modulation of DBC1 [PDF]

, 2013
BACKGROUND We have previously identified kinase suppressor of ras-1 (KSR1) as a potential regulatory gene in breast cancer. KSR1, originally described as a novel protein kinase, has a role in activation of mitogen-activated protein kinases.

Poly(ADP-ribosyl)ation is involved in the epigenetic control of TET1 gene transcription [PDF]

, 2014
TET enzymes are the epigenetic factors involved in the formation of the Sixth DNA base 5-hydroxymethylcytosine, whose deregulation has been associated with tumorigenesis.

DLC2 modulates angiogenic responses in vascular endothelial cells by regulating cell attachment and migration. [PDF]

, 2010
Deleted in liver cancer 1 (DLC1) is a RhoGTPase activation protein-containing tumor suppressor that associates with various types of cancer. Although DLC2 shares a similar domain structure with that of DLC1, the function of DLC2 is not well characterized.

Genetic diversity and silencing suppression effects of Rice yellow mottle virus and the P1 protein

Virology Journal, 2008
Background PTGS (post-transcriptional gene silencing) is used to counter pathogenic invasions, particularly viruses. In return, many plant viruses produce proteins which suppress silencing directed against their RNA.

Epigenetic Silencing of Novel Tumor Suppressors in Malignant Melanoma [PDF]

Cancer Research, 2006
Abstract Malignant melanoma is a common and frequently lethal disease. Current therapeutic interventions have little effect on survival, emphasizing the need for a better understanding of the genetic, epigenetic, and phenotypic changes in melanoma formation and progression.

Cucumber Mosaic Virus 2b Protein Subcellular Targets and Interactions: Their Significance to RNA Silencing Suppressor Activity

Molecular Plant-Microbe Interactions, 2010
The RNA silencing suppressor activity of the 2b protein of Cucumber mosaic virus (CMV) has been variously attributed to its nuclear targeting, its interaction with and inhibition of Argonaute 1 (AGO1), or its ability to bind small RNAs in vitro.

Ageing And Cancer As Diseases Of Epigenesis [PDF]

, 2009
Cancer and ageing are often said to be diseases of development. During the past fifty years, the genetic components of cancer and ageing have been intensely investigated since development, itself, was seen to be an epiphenomenon of the genome.

CADM1 is a strong neuroblastoma candidate gene that maps within a 3.72 Mb critical region of loss on 11q23 [PDF]

, 2008
Background: Recurrent loss of part of the long arm of chromosome 11 is a well established hallmark of a subtype of aggressive neuroblastomas. Despite intensive mapping efforts to localize the culprit 11q tumour suppressor gene, this search has been ...

Snail silences suppressor

Journal of Experimental Medicine, 2009
The Snail protein has a new carcinogenic trick up its sleeve, according to Massoumi et al. on page 221. Figure 1 Downregulation of the tumor suppressor, CYLD (red, asterisks), contributes to malignant melanoma. In many different types of cancer, the transcriptional repressor Snail helps tumors spread by dampening the expression
