چکیده

Uveal melanoma (UM) is the most common adult intraocular tumor. UM often involves activating mutations in guanine nucleotide binding protein (G protein), q polypeptide (GQ), or G Protein, α 11 (G11). We show that the Yes-associated protein (Yap) inhibitor verteporfin blocks tumor growth of Gq/11-mutated UM cells.

Oncogenic GNAQ and GNA11 Mutations in Uveal Melanoma in Chinese

PURPOSE To examine whether GNAQ and GNA11 somatic mutations previously identified in uveal melanomas of Caucasians are associated with uveal melanomas in Chinese patients. METHODS Uveal melanomas treated by primary enucleation in Chinese patients underwent a mutation analysis of GNAQ and GNA11 with sequencing of exon 5 and exon 4. RESULTS The study included 50 patients with uveal melanoma a...

Oncotargeting G proteins: The Hippo in the room

The core components of the Hippo pathway are conserved from flies to mammals. In humans, these include a kinase cascade initiated by the Hippo kinase MST1/2 associated with the adaptor protein WW45/SAV1, and LATS1/2 in complex with MOB1, which in turn, phosphorylates and inhibits the mammalian transcription co-activator YAP and its related protein TAZ. YAP plays a critical role in organ size co...

Combination small molecule MEK and PI3K inhibition enhances uveal melanoma cell death in a mutant GNAQ- and GNA11-dependent manner.

PURPOSE Activating Q209L/P mutations in GNAQ or GNA11 (GNAQ/11) are present in approximately 80% of uveal melanomas. Mutant GNAQ/11 are not currently therapeutically targetable. Inhibiting key down-stream effectors of GNAQ/11 represents a rational therapeutic approach for uveal melanomas that harbor these mutations. The mitogen-activated protein/extracellular signal-regulated kinase/mitogen-act...

Frequent GNAQ, GNA11, and EIF1AX Mutations in Iris Melanoma.

Purpose The most common malignant intraocular tumors with a high mortality in adults are uveal melanomas. Uveal melanomas arise most frequently in the choroid or ciliary body (97%) and rarely in the iris (3%). Whereas conjunctival and posterior uveal (ciliary body and choroidal) melanomas have been studied in more detail genetically, little data exist regarding iris melanomas. Methods In our ...

High throughput mass spectrometry-based mutation profiling of primary uveal melanoma.

PURPOSE We assessed for mutations in a large number of oncogenes and tumor suppressor genes in primary uveal melanomas using a high-throughput profiling system. METHODS DNA was extracted and purified from 134 tissue samples from fresh-frozen tissues (n = 87) or formalin-fixed, paraffin-embedded tissues (n = 47) from 124 large uveal melanomas that underwent primary treatment by enucleation. DN...
