Targeting oncogenic Ras signaling in hematologic malignancies.
Ras proteins are critical nodes in cellular signaling that integrate inputs from activated cell surface receptors and other stimuli to modulate cell fate through a complex network of effector pathways. Oncogenic RAS mutations are found in ∼25% of human cancers and are highly prevalent in hematopoietic malignancies. Because of their structural and biochemical properties, oncogenic Ras proteins a...
متن کاملTargeting Bcl-2 stability to sensitize cells harboring oncogenic ras
The pro-survival factor Bcl-2 and its family members are critical determinants of the threshold of the susceptibility of cells to apoptosis. Studies are shown that cells harboring an oncogenic ras were extremely sensitive to the inhibition of protein kinase C (PKC) and Bcl-2 could antagonize this apoptotic process. However, it remains unrevealed how Bcl-2 is being regulated in this apoptotic pr...
متن کاملTargeting oncogenic drivers.
Cancer is a genetic disease caused by a series of somatic and/or germline mutations. The roles of oncogenes and tumor suppressors in cancer molecular origin have been well established. Targeting oncogene products has become an attractive therapeutic strategy with great clinical success, whereas tumor suppressors are considered 'undruggable' because current technology is not able to restore tumo...
متن کاملAntibody targeting intracellular oncogenic Ras mutants exerts anti-tumour effects after systemic administration
Oncogenic Ras mutants, frequently detected in human cancers, are high-priority anticancer drug targets. However, direct inhibition of oncogenic Ras mutants with small molecules has been extremely challenging. Here we report the development of a human IgG1 format antibody, RT11, which internalizes into the cytosol of living cells and selectively binds to the activated GTP-bound form of various o...
متن کاملSuppression of Egr-1 transcription through targeting of the serum response factor by oncogenic H-Ras.
The transcription factor Egr-1 functions as a key regulator in cellular growth, differentiation, and apoptosis. The loss of Egr-1 expression is closely associated with tumor development, although the molecular mechanism behind the suppression of Egr-1 is largely unknown. In this report, we show that growth factor-induced transcriptional activation of Egr-1 gene is downregulated by chronic expre...
