The effect of oxidation on the stability of G-quadruplex DNA : implications for oncogene expression [PDF]

open access: yes, 2011
G-quadruplexes (G4-DNA) are a class of secondary structures formed from Guanine rich sequences. In recent years these structures have been implicated in both telomere maintenance and oncogene expression, and have been shown to be abundant in upstream ...

Not all NTRK fusions in mesenchymal neoplasia are driver events: implications on classification and targeted therapy. [PDF]

open access: yesJ Pathol Clin Res
Abstract NTRK fusions drive the pathogenesis of a distinctive group of mesenchymal neoplasms with significant impact on classification and targeted therapy. However, unexpected NTRK fusions have been reported in other sarcoma entities, raising uncertainty over their specificity and clinical management.

Malignant progression of liver cancer progenitors requires lysine acetyltransferase 7–acetylated and cytoplasm‐translocated G protein GαS

open access: yesHepatology, EarlyView., 2022
KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.

The degradation of p53 and its major E3 ligase Mdm2 is differentially dependent on the proteasomal ubiquitin receptor S5a. [PDF]

open access: yes, 2014
p53 and its major E3 ligase Mdm2 are both ubiquitinated and targeted to the proteasome for degradation. Despite the importance of this in regulating the p53 pathway, little is known about the mechanisms of proteasomal recognition of ubiquitinated p53 and

MDM2 negatively regulates the human telomerase RNA gene promoter [PDF]

open access: yes, 2005
<b>Background:</b> We have previously demonstrated that NF-Y and Sp1 interact with the human telomerase RNA (hTR) promoter and play a central role in its regulation. We have also shown that pRB activates the hTR promoter, but the mechanism

MAGE-A cancer/testis antigens inhibit MDM2 ubiquitylation function and promote increased levels of MDM4 [PDF]

open access: yes, 2015
Melanoma antigen A (MAGE-A) proteins comprise a structurally and biochemically similar sub-family of Cancer/Testis antigens that are expressed in many cancer types and are thought to contribute actively to malignancy.

Ras-mediated phosphorylation of a conserved threonine residue enhances the transactivation activities of c-Ets1 and c-Ets2 [PDF]

open access: yes, 1996
The Ras oncogene products regulate the expression of genes in transformed cells, and members of the Ets family of transcription factors have been implicated in this process.

A p53-independent role for the MDM2 antagonist Nutlin-3 in DNA damage response initiation. [PDF]

open access: yes, 2011
BACKGROUND: The mammalian DNA-damage response (DDR) has evolved to protect genome stability and maximize cell survival following DNA-damage. One of the key regulators of the DDR is p53, itself tightly regulated by MDM2. Following double-strand DNA breaks

The role of the proto-oncogene Ski in cortical development [PDF]

open access: yes, 2013
The proto-oncogene Ski is an evolutionary conserved protein associated with various cellular processes such as proliferation and differentiation as well as transformation and tumor progression.
