Long noncoding RNAs (lncRNAs) are crucial regulatory molecules involved in diverse biological processes and human diseases, including preeclampsia (PE). The lncRNA growth arrest associated lncRNA 1 (GASAL1) has been implicated in multiple malignant solid tumors and other diseases, while it is poorly known as the potential molecular mechanism of GASAL1 in PE. In this study, GASAL1 was significantly downregulated in the placentas’ of tissues from primipara with PE and trophoblast cell lines. Then, the upregulation of GASAL1 dramatically decreased proliferation and invasion and enhanced apoptosis in HTR-8/SVneo and JAR cells. Bioinformatics tool predicated that there is a potential interaction between GASAL1 and serine/arginine splicing factor 1 (SRSF1). RNA pull-down assays showed that GASAL1 directly binds with SRSF1 that could promote cell proliferation and invasion and suppress cell apoptosis. Further research showed that promoting effects of trophoblasts proliferation and invasion caused by co-transfecting GASAL1 and SRSF1 into HTR-8/SVneo and JAR cells were impaired by SRSF1 knockdown. Moreover, inhibition of the mammalian target of rapamycin (mTOR) activity by rapamycin influenced the effects of GASAL1 on cell proliferation, invasion, and apoptosis. Taken together, these findings suggest that lncRNA GASAL1 interacts with SRSF1 to regulate the proliferative, invasive, and apoptotic abilities of trophoblast cells via the mTOR signaling pathway.

A B S T R A C TIntroduction To explore the effect of ethynil estradiol and desogestrel onproliferation and apoptosis hydatidiform mole trophoblast cell. Methods: From April2008 until March 2009, we collected 15 samples of hydatidiform mole tissue.Trophoblast cells was isolated and culture at RPMI 20% FBS medium. Only 7samples (46%)shown good growth. Cell was identified using cytology and β HCG test.Trophoblast cells good quality than devided into three groups observation. Firstgroup get ethynil estradiol 10 nmol/mL, second group get desogestrel 100 nmol/mL,Third group get DMSO 1%. Cells incubated and observe at 24, 48, 72, 96 hours. Cellcycle, apoptosis and β HCG was evaluated at each time observation. Cell cycleevaluation using BD cycle test plus DNA reagent, apoptosis evaluation using FITC-Annexin V. Analyze using FACSCalibur flowcytometer. β HCG evaluation usingAbbott AxSym total β-HCG reagent pack. Results: The group of cell that get ethynilestradiol in concentration 10 nmol/mL had cell proliferation index, amount cells andβ HCG level higher than control after 72 hours observation. The group of cell thatget desogestrel in concentration 100 nmol/mL have cell proliferation index, amountcells and β HCG level lower than control after 48 hours observation. There are nodifferences of apoptosis between the two group and control. Conclusion: Ethynilestradiol will increase proliferation of hydatidiform mole trophoblast cell, whiledesogestrel will decrease proliferation of hydatidiform mole trophoblast cell. Thereare no effect of ethynil estradiol and desogestrel on apoptosis of hydatidiform moletrophoblast cell.
