Regulation of the Ras Signaling Network in C. Elegans Development
… LET-60/Ras switches effectors to use the RGL-1/RalGEF-RAL-1/Ral modulatory signaling cascade to promote 2˚ fate in support of LIN-12. The goals of this research are to define principles by which signaling networks function and to identify an effector cascade downstream of RAL-1. RAL-1 signals …

Evaluation of Chronic RalGTPase Activation as a Core Specifier of Oncogenic Transformation
… family Ral guanine nucleotide exchange factors (RalGEFs). Previous studies have demonstrated that RalA and RalB collaborate to maintain tumorigenicity through regulating both proliferation and survival. Remarkably, RalB is specifically required for survival in Ras-dependent tumor cells rather …

Ras Intrinsic and Extrinsic Pathways in Human Cancer
… intrinsic signaling including the Raf, PI3K, and RalGEF pathways. In regards to the latter, RalGEFs activate two other small GTPases, RalA and RalB. The role of these two proteins in Ras-mediated cancer was poorly understood. I thus assessed the requirement of RalA and RalB in tumor metastasis …
