S1PR3–G12-biased agonist ALESIA targets cancer metabolism and promotes glucose starvation [HeLa RNA-seq]

Project description:Cancer tissues possess less glucose than surrounding normal tissue, because cancer cells predominantly produce energy by glycolysis than oxidative phosphorylation even in the presence of an adequate oxygen supply (Warburg effect). We found a novel compound ALESIA which causes apoptosis of malignant cells at a low glucose condition from an original phenotypic screening. Identified target molecule of ALESIA was Sphingosine-1-phosphate receptor 3 (S1PR3). Being different from the natural ligand, ALESIA selectively stimulated S1PR3-G12 coupling to S1PR3 without suppression by β-arrestin recruitment and continuously promoted NO synthesis. To reduce the enhanced oxidative stress, NAPDH production through pentose-phosphate pathway and resulting consumption of glucose were promoted in ALESIA-treated cells. ALESIA therefore accelerated glucose starvation of cancer cells and preferentially killed them both in vitro and in vivo.

Mapping AT1R biased signaling using proximity-labeling and proteomics identifies diverse actions of biased agonists

Project description:Angiotensin II type 1 receptors (AT1Rs) are one of the most widely studied G protein-coupled receptors. To fully appreciate the diversity in cellular signaling profiles activated by AT1R transducer-biased ligands, we utilized peroxidase-catalyzed proximity labeling to capture proteins in close proximity to AT1Rs in response to six different ligands: Angiotensin II (full agonist), S1I8 (partial agonist), TRV055 and TRV056 (G protein-biased agonists), TRV026 and TRV027 (β-arrestin biased agonists) at 90s, 10min, and 60min after stimulation. We systematically analyzed the kinetics of AT1R trafficking and determined that distinct ligands lead AT1R to different cellular compartments for downstream signaling activation and receptor degradation/recycling. Distinct proximity labelling of proteins from a number of functional classes, including GTPases, adaptor proteins, and kinases were activated by different ligands suggesting unique signaling and physiological roles of the AT1R. Ligands within the same class, i.e. either G protein-biased or -arrestin-biased, shared high similarity in their labelling profiles. Comparison between ligand classes revealed distinct signaling activation such as greater labeling by G protein biased ligands on ESCRT-0 complex proteins that act as sorting machinery for ubiquitinated proteins. Our study provides a comprehensive analysis of AT1R receptor trafficking kinetics and signaling activation profiles induced by distinct classes of ligands.

Delineation of a conserved arrestin-biased signaling repertoire in vivo

Project description:Biased G protein-coupled receptor agonists engender a restricted repertoire of downstream events from their cognate receptors, permitting them to produce mixed agonist-antagonist effects in vivo. While this opens the possibility of novel therapeutics, it complicates rational drug design, since the in vivo response to a biased agonist cannot be reliably predicted from its in vitro efficacy. We have employed novel informatic approaches to characterize the in vivo transcriptomic signature of the arrestin pathway-selective parathyroid hormone analog [D-Trp12, Tyr34]-bPTH(7-34) in six different murine tissues after chronic drug exposure. We find that [D-Trp12, Tyr34]-bPTH(7-34) elicits a distinctive arrestin-signaling focused transcriptomic response that is more coherently regulated across tissues than that of the pluripotent agonist, hPTH(1-34). This arrestin-focused network is closely associated with transcriptional control of cell growth and development. Our demonstration of a conserved arrestin-dependent transcriptomic signature suggests a framework within which the in vivo outcomes of arrestin-biased signaling may be generalized.

AG3C glucose starvation time course

Project description:This data set consists of a long term glucose starvation time course of E. coli grown in minimal media for up to two weeks. Unlike previous studies of long term starvation,Our study focuses on the physiological response of E. Coli in stationary phase as a result of being starved for glucose, not on the genetic adaptation of E. coli to utilize alternative nutrients.
