Abstract

Background

Diagnosis of uterine sarcomais is a challenging task for clinicians because its position is not easily accessible by current conventional techniques. In addition, standardized treatment for uterine sarcoma has not yet been established due to its rarity and heterogeneity.

Hypothesis/Purpose

We investigated the apoptotic cell death of uterine sarcoma cells (SK-UT-1B) induced by Gyejibokryunghwan (GBH). GBH, an herbal medicine, has been widely used for gynecological diseases in Koean medicine.

Methods

SK-UT-1B cells were treated with GBH of varying concentrations from 0 to 500 µg/ml. The mechanism of cell death was investigated through multiple analysis methods, including flow cytometry, cell cycle, and western blotting.

Results

Flow cytometric analysis revealed that the number of apoptotic cells increased in a GBH dose-dependent manner. The cell populations of sub-G1 and G0/G1phases were increased by GBH treatment, indicating apoptosisand cell arrest, while the population of S and G2/M phases decreased. With GBH, the expression levels of cleaved caspase-3, -6, and -9 were upregulated, while the expression levels of pro-caspase-3, -6, and -9 were down-regulated in SK-UT-1B cells.

Conclusion

These results are the first observation of uterine sarcoma cell death induced by GBH and confirmation of the mechanism of cell death, which occurred through the intrinsic apoptotic pathway. Clinically, uterine sarcoma has a poor prognosis with no appropriate treatment. GBH may become a new treatment modality for uterine sarcoma.
