Diese Aktie bringt mich um den Verstand. Vollkommen gegen den Trend, werden riesige Pakete verkauft. 🫣

Danke für das teilen der Info hier 👍

Peroxisome proliferator activated receptor alpha (PPARα) is a transcription factor and master regulator of fatty acid oxidation. PPARα ligands modulate the switch between co-activator and co-repressor transcription complexes at PPARα-controlled target genes. In addition, PPARα has been shown to transrepress NF-κB signaling and inhibit angiogenesis. Renal cell carcinoma (RCC) expresses high levels of PPAR-α and is a highly angiogenic cancer. Current frontline treatments for RCC include chemotherapy, anti-angiogenics, and immunotherapy but are limited by the immune suppressive state of the tumor microenvironment. TPST-1120 is a novel PPARα antagonist for the treatment of cancer patients that binds in the ligand binding domain, positioning the AF-2 activation helix in an inactive conformation. The inactive conformation has a lower affinity for co-activator motifs and reduces activation of PPARα regulated genes. In a CHO-based reporter cell line, TPST-1120 potently competed against the PPARα-specific agonist GW7647 (IC50 = 36 nM at 20 nM GW7647) and an endogenous PPARα agonist oleoylethanolamide (OEA; IC50 = 15 nM at 30 µM OEA). Furthermore, in an enzyme fragment complementation assay, we demonstrated that TPST-1120 inhibited agonist-induced binding of PPARα to MED1 by destabilizing the co-activator complex thereby stabilizing the inactive conformation of PPAR-α. In a murine model of renal cell adenocarcinoma (RENCA), TPST-1120 treatment for 12 days (30 mg/kg qd) reduced tumor growth by 52% as a monotherapy (p
