Description

Application

Thapsigargin has been used as an endoplasmic reticulum (ER) stress inducer:

• to study its effect on cyclase-associated protein 2 (CAP2) expression in liver cancer cells[1]
• in the cell viability experiment using ARPE -19 cells (human retinal pigment epithelial cells)[2]
• to study its effect on lipocalin 2 (LCN2) glycosylation in primary hepatocytes[3]
• to study the consequences of calcium depletion in the endoplasmic reticulum (ER) of cells[4]
• to study its effect on tissue inhibitor of metalloproteinases-1 (TIMP-1) mRNA expression in rat Sertoli cells

Biochem/physiol Actions

Potent, cell-permeable, IP₃-independent intracellular calcium releaser.

Thapsigargin is a potent, cell-permeable, IP₃-independent intracellular calcium release. It blocks the transient increase in intracellular Ca²⁺ induced by angiostatin and endostatin. It also induces apoptosis by disrupting intracellular free Ca²⁺ levels and is incorporated into chemotherapeutic prodrug formulations.

General description

Thapsigargin, a guaianolide-type sesquiterpene lactone,[5] is a widely used inhibitor of the ubiquitous sarcoplasmic/endoplasmic reticulum Ca²⁺ ATPase (SERCA)[6]. It can activate endoplasmic reticulum (ER) stress and the unfolded protein response (UPR).[7] Thapsigargin is a natural phytochemical found in the roots and fruits of Mediterranean plants from Thapsia garganica (Apiaceae) species.[5] Thapsigargin promotes the release of translational arrest and induces proteome-wide changes in metabolic pathways within cells infected with coronavirus (CoV).[7]
