Biological Activity for trans-ISRIB

trans-ISRIB is a potent integrated stress response (ISR) inhibitor; reverses the effects of eIF2α phosphorylation (IC50 = 5 nM) and restores cell translation capacity. Acts downstream of PERK, targeting interactions between eIF2α kinases and elF2B. Blocks ATF4 production without altering the IRE1 or ATF6 responses in vitro. Displays memory enhancement in hippocampus-dependent spatial and fear-associated learning in rodents. trans-ISRIB promotes survival of pluripotent stem cells in culture when used in combination with Chroman 1 (Cat. No. 7163), Emricasan (Cat. No. 7310), and Polyamine Supplement x1000 (lyophilized) (Cat. No. 7739), a combination known as CEPT. When used as part of the CEPT cocktail, trans-ISRIB improves survival of differentiated cells following cryopreservation. Brain penetrant.

Inhibits integrated stress response in HEK293 cells.
By mandi gandelman on 05/01/2019
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: HEK293

Used trans-ISRIB to inhibit the integrated stress response (ISR) in HEK293 cells. Induced the ISR and added ISRIB (100 and 500nM) overnight. Evaluated p-eif2a (unchanged) and cleaved caspase 3 (increased in a dose-dependent manner with ISRIB.

Learning & Memory Poster

Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.
