PI3K inhibition activates SGK1 via a feedback loop to promote chromatin-based regulation of ER-dependent gene expression
- Authors
- Toska, EnedaKoche, Richard Patrick
- Description
Summary from GEO: "The phosphoinositide 3-kinase (PI3K) pathway integrates extracellular stimuli to phosphorylate and activate key downstream effectors such as AKT and serum-and glucocorticoid-inducible kinase (SGK1). We have previously reported that the PI3K pathway regulates ER-dependent transcription in breast cancer through the phosphorylation of the epigenetic regulator KMT2D by AKT. Here, we...

A paracrine IGF1/IGF1R-PI3K signaling loop underlies resistance to CSF-1R inhibition in GBM

- Description
Summary from GEO: "Glioblastoma multiforme (GBM) is the most aggressive form of glioma, and is notorious for its terminal prognosis and lack of responsiveness to current treatment approaches. The brain tumor microenvironment (TME) represents a largely untapped reservoir of therapeutic target options in GBM. Here we have focused on the interplay between glioma cells and tumor-associated macrophages/...

Microenvironment-driven IGF-1R/PI3K signaling underlies acquired resistance to CSF1R inhibition in gliomas (CGH)
- Authors

- Description
Summary form GEO: "Macrophages accumulate with glioblastoma multiforme (GBM) progression, and can be acutely targeted via inhibition of colony stimulating factor-1 receptor (CSF-1R) to regress high-grade tumors in animal models. However, whether and how resistance emerges in response to sustained CSF-1R blockade is unknown. Here, we investigate whether long-term CSF-1R inhibition can stably regress...
