RTKs can activate Ras, a protein that is tethered to the plasma membrane, by causing it to bind GTP. Once activated, Ras can do a variety of things. In this example, it activates an enzymatic cascade ...

As many as 50 percent of human cancer cases -- across a wide variety of tissues -- involve defects in a common cellular growth signaling pathway. These defects have so far defied most attempts to ...

Pancreatic ductal adenocarcinoma (PDAC) is characterized clinically by poor survival and mechanistically by KRAS- and autophagy-dependent growth. We and others previously demonstrated that inhibition ...

The effective targeting of RAS-mutant acute myeloid leukemia (AML) still remains a challenge; RAS mutations are tied to relapse to targeted therapy, such as resistance to FLT3 inhibitors due to the ...

Ras mutations occur as an early event in many human tumours of epithelial origin, including thyroid. Using primary human thyroid epithelial cells to model tumour initiation by Ras, we have shown ...

Patients with NSCLC who underwent RT for spine metastasis and tumor genetic profiling were ascertained. Associations between driver gene mutations incidence of local failure were analyzed, followed by ...

Erasca, Inc. presents promising preclinical data on ERAS-0015 and ERAS-4001 targeting RAS/MAPK pathway cancers at AACR meeting. Erasca, Inc. presented new preclinical data at the American Association ...

Mitogen-activated protein kinase (MAPK) networks are essential for the transmission of extracellular signals into appropriate intracellular responses. Prototypical MAPK activation implements a ...

Two molecular pathways—one that causes cancer and one that protects against it—compete to control cellular levels of one protein, according to a new study by A*STAR researchers and colleagues.The ...
