Gene Information

human ... DHCR24(1718) , EBP(10682)

Application

Triparanol has been used to inhibit cholesterol biosynthesis in lipid rafts1. Triparanol has also been used as a 3β-hydroxysterol-Δ24-reductase inhibitor to study its effect on delayed-rectifier potassium current (Iks) channels2.

Biochem/physiol Actions

Triparanol is known to repress Hedgehog signaling in cancer cells and can also inhibit tumor growth3.
Desmosterol Delta24 (D24) reductase inhibitor.

Preparation Note

Triparanol is soluble in DMSO at 20 mg/ml and is also soluble in alcohol. It is slightly soluble in olive oil and is insoluble in water.

Like many solid tumors, sarcomas are heterogeneous and include a small fraction of the so-called side population (SP) cells with stem-like tumor-initiating potential. Here, we report that SP cells from a soft tissue tumor of enigmatic origin termed undifferentiated pleomorphic

Chondrosarcoma is a malignant cartilage tumor that may arise from benign precursor lesions, such as enchondromas. Some cases of multiple enchondromas are caused by a mutation that results in constitutive activation of Hedgehog-mediated signaling. We found that chondrosarcomas expressed high
