(Rac)-AAA is a regulator and inhibitor targeting GPR75. By blocking the 20-HETE-induced downregulation of GPR75 expression, (Rac)-AAA effectively inhibits the activation of key downstream signaling pathways including EGFR, AKT, NF-κB and FAK. (Rac)-AAA reverses 20-HETE-mediated epithelial-mesenchymal transition, which is specifically characterized by downregulating vimentin (vimentin), upregulating E-Cadherin, as well as reducing MMP-2 activity and cancer cell migration ability. (Rac)-AAA also abolishes the 20-HETE-induced upregulation of HIC-5 expression and anchorage-independent growth, and modulates the subcellular localization of PKC-α and phosphorylated AKT. (Rac)-AAA is investigated in androgen-independent prostate cancer (castration-resistant prostate cancer).

Description

(Rac)-AAA reverses 20-HETE-mediated epithelial-mesenchymal transition, which is specifically characterized by downregulating vimentin (vimentin), upregulating E-Cadherin, as well as reducing MMP-2 activity and cancer cell migration ability. (Rac)-AAA also abolishes the 20-HETE-induced upregulation of HIC-5 expression and anchorage-independent growth, and modulates the subcellular localization of PKC-α and phosphorylated AKT. (Rac)-AAA is investigated in androgen-independent prostate cancer (castration-resistant prostate cancer)[1].

IC50 & Target

MMP-2

 

In Vitro

(Rac)-AAA (5-10 μM; 12 h) reverses the 20-HETE-induced reduction in GPR75 expression, and increases baseline GPR75 expression in PC-3 human prostate cancer cells[1].
(Rac)-AAA (5-10 μM; 2 h) reduces 20-HETE-induced phosphorylation of EGFR, AKT, and NF-κB, and increases baseline p38 phosphorylation in PC-3 human prostate cancer cells[1].
(Rac)-AAA (5-10 μM; 24 h) reverses 20-HETE-induced epithelial-mesenchymal transition by restoring E-cadherin expression and reducing or abrogating vimentin expression in PC-3 human prostate cancer cells[1].
(Rac)-AAA (5-10 μM; 24 h) reduces or abrogates 20-HETE-induced MMP-2 activity in conditioned medium from PC-3 human prostate cancer cells[1].
(Rac)-AAA (5 μM; 21 days) abrogates the increase in anchorage-independent colony formation induced by 5,14-HEDGE in PC-3 human prostate cancer cells[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
