PREX2 Antibody, FITC conjugated

1. Study demonstrates that miR-637 inhibites melanoma cell proliferation by activation of AKT signaling pathway and induces apoptosis through regulation of Bcl-2/Bax expression via targeting P-REX2a. PMID: 30213289
2. MiR-338-3p suppresses the TNF-alpha-induced lipogenesis in sebocytes by targeting PREX2a and down-regulating PI3K/AKT signaling. PMID: 28597147
3. complex signaling mechanisms that involve PREX2, PI3K/AKT/PTEN and downstream epigenetic machinery to deregulate expression of key cell cycle regulators PMID: 27111337
4. PREX2 was identified as a frequently mutated gene in human melanoma. .. mutation of PREX2 can accelerate human melanoma growth. PMID: 28100393
5. The rapid tumor onset observed in this replication attempt, compared to the original study, makes the detection of accelerated tumor growth in PREX2 expressing NRAS(G12D) melanocytes extremely difficult. PMID: 28100394
6. Elevated PREX2 protein expression is associated with pathogenesis of hepatocellular carcinoma. PMID: 28205209
7. knockdown of PREX2a may effectively inhibit the malignant phenotype of glioma. PMID: 26795161
8. The results of the present study suggested that PREX2a may act as an oncogene in osteosarcoma via the inhibition of PTEN activity and activation of PI3K signaling. PMID: 26718453
9. findings identify PREX2 as a mediator of NRAS-mutant melanoma development that acts through the PI3K/PTEN/Akt pathway to regulate gene expression of a cell cycle regulator PMID: 26884185
10. second messengers activate the Rac1 signal, which sets in motion a cascade whereby PAKs phosphorylate and negatively regulate PREX2 to decrease Rac1 activation. PMID: 26438819
11. PREX2 mutants are likely selected in cancer to escape PTEN-mediated inhibition of invasion. PMID: 25829446
12. CXCL9 is involved in the invasion ability of hepatocellular carcinoma cells possibly through up-regulation of its potential effector PREX2. PMID: 25151370
13. Results demonstrate that miR-338-3p affects gastric cancer progression through PTEN-AKT signaling by targeting P-Rex2a in gastric cancer cells PMID: 24375644
14. P-REX2 PH-domain-mediated inhibition of PTEN has a role in regulating insulin sensitivity and glucose homeostasis PMID: 24367090
15. MiR-338-3p affects the PTEN/Akt pathway by down-regulating PREX2a. PMID: 24140344
16. Analysis of whole-genome sequence data identified PREX2 (phosphatidylinositol-3,4,5-trisphosphate-dependent Rac exchange factor 2)--a PTEN-interacting protein and negative regulator of PTEN in breast cancer--as a significantly mutated gene with a mutation frequency of approximately 14% in an independent extension cohort of 107 human melanomas PMID: 22622578
17. suggests that aberrant control of PTEN by P-REX2a may represent a key tumorigenic mechanism, in agreement with recent studies supporting the pathological relevance of several other proposed PTEN regulators PMID: 19861688
18. P-REX2 may serve as a novel link between Rac activation and the PI-3 kinase pathway. PMID: 15304342
19. P-Rex2 is a 183 kDa protein that activates the small GTPase Rac and is regulated by phosphatidylinositol (3,4,5)-trisphosphate. PMID: 15304343
20. the pleckstrin homology domain of the Dbl family guanine nucleotide exchange factor P-Rex2 has a role in substrate specificity and recognition PMID: 15897194
21. identified P-REX2a as a PTEN-interacting protein; P-REX2a inhibited PTEN lipid phosphatase activity & stimulated the PI3K pathway only in the presence of PTEN; P-REX2a is a component of the PI3K pathway that can antagonize PTEN in cancer cells PMID: 19729658
