          Background

          Thapsigargin is an inhibitor of microsomal Ca2+-ATPase, Thapsigargin inhibits the carbachol-evoked [Ca2+]i-transients with IC50 value of 0.353 nM[1].
          Thapsigargin may induce cell apoptosis in MH7A cells in a time- and dose-dependent manner, and the percentages of cell death reached 44.6% at thapsigargin concentration of 1 μM treated for 4 days compared to the control. The protein and mRNA levels of cyclin D1 decreased gradually with the increasing of thapsigargin concentration and treatment times[2].
          In regards to vivo results, tunicamycin is superior in not only inducing ER stress but also recapturing the metabolic alterations associated with ER stress[3].
