3,3′,5’-Triiodo-L-thyronine, also known as reverse T3 (rT3), is a thyroid hormone generated by deiodination of the prohormone thyroxine. It is about 1,000-fold less active at the thyroid hormone receptors TRα and TRβ than 3,3′,5-triiodo-L-thyronine (Item No. 16028) and commonly described as inactive.{28789,28791} However, high serum levels of rT3 are found in neonates and in certain conditions.{28795,28793,28790,28792} It reportedly activates TRΔα1, a native form of TRα that lacks a nuclear localization signal and functions in the cytoplasm.{28794} Through this action, rT3 initiates actin polymerization, particularly in astrocytes and neurons.{28794}

  • A small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state; activity is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM

    SC-1 – 5 mg

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal. SC-1 is a small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state.{14533} The activity of SC-1 is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM, respectively.{14533} Inhibition of RasGAP increases Ras signaling via the PI3-kinase pathway which promotes self-renewal, whereas inhibition of ERK blocks differentiation.
