Ras Enhances Myc Protein Stability [PDF]
Molecular Cell, 1999 Various experiments have demonstrated a collaborative action of Myc and Ras, both in normal cell growth control as well as during oncogenesis. We now show that Ras enhances the accumulation of Myc activity by stabilizing the Myc protein. Whereas Myc has a very short half-life when produced in the absence of mitogenic signals, due to degradation by the ...

κB-Ras Proteins Regulate Both NF-κB-Dependent Inflammation and Ral-Dependent Proliferation
Cell Reports, 2014 The transformation of cells generally involves multiple genetic lesions that undermine control of both cell death and proliferation. We now report that κB-Ras proteins act as regulators of NF-κB and Ral pathways, which control inflammation/cell death and

Inhibition of Ral GTPases Using a Stapled Peptide Approach. [PDF]
, 2016 Aberrant Ras signaling drives numerous cancers, and drugs to inhibit this are urgently required. This compelling clinical need combined with recent innovations in drug discovery including the advent of biologic therapeutic agents, has propelled Ras back ...

ETS1 is a genome-wide effector of RAS/ERK signaling in epithelial cells [PDF]
, 2014 The RAS/ERK pathway is commonly activated in carcinomas and promotes oncogenesis by altering transcriptional programs. However, the array of cis-regulatory elements and trans-acting factors that mediate these transcriptional changes is still unclear. Our

The Ins and Outs of RAS Effector Complexes
Biomolecules, 2021 RAS oncogenes are among the most commonly mutated proteins in human cancers. They regulate a wide range of effector pathways that control cell proliferation, survival, differentiation, migration and metabolic status.

A role for the Ral guanine nucleotide dissociation stimulator in mediating Ras-induced transformation [PDF]
, 1996 Oncogenic Ras transforms cells through the activation of multiple downstream pathways mediated by separate effector molecules, one of which is Raf. Here we report the identification of a second ras-binding protein that can induce cellular transformation ...

PIK3CB and K-ras in oral squamous Cell carcinoma. A possible cross-talk!
Journal of Orofacial Sciences, 2014 Background: PIK3 and K-ras are signal transducing proteins involved and mediating many responses related to cell cycle growth regulation. Until date, there has been only limited evidence about the expression of K-ras and PKI3CB in oral squamous cell ...

RASSF4: Regulator of plasma membrane PI(4,5)P2. [PDF]
, 2017 Phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) is a negatively charged phospholipid that plays a major role in recruiting and regulating proteins at the plasma membrane-cytosol interface. In this issue, Chen et al. (2017. J. Cell Biol. https://doi.org/

Evaluating The Role Of Nitric Oxide Synthase In Oncogenic Ras-Driven Tumorigenesis
Redox Biology, 2015 We previously reported that oncogenic KRAS activation of the PI3K/AKT pathway stimulates the remaining wild-type HRAS and NRAS proteins in a manner dependent upon both eNOS expression and C118 in HRAS and NRAS, which promoted tumor growth.

eLife, 2020 The RAS proteins are GTP-dependent switches that regulate signaling pathways and are frequently mutated in cancer. RAS proteins concentrate in the plasma membrane via lipid-tethers and hypervariable region side-chain interactions in distinct nano-domains.
