HOTAIR polymorphism rs1899663 was associated with BC, CC, and OC susceptibility to a certain extent, (alleles T/G OR = 0.90 [95% CI, 0.69-1.16]; in the codominant model: GT/GG OR = 0.81 [95% CI, 0.50-1.30], TT/GG OR = 1.04 [95% CI, 0.63-1.72]; dominant model: GT + TT/GG OR = 0.82 [95% CI, 0.52-1.29]; and recessive model: TT/GT + GG OR = 1.21 [95% CI, 0.76-1.94]).
In the current study, we aimed to uncover the biological role of lncRNA HOTAIR and its underlying regulatory mechanism in the progression and metastasis of ovarian cancer.
These findings propose that HOTAIRrs920778 polymorphism influences ovarian cancer susceptibility and prognosis, and further studies are warranted in other populations.
In conclusion, HOTAIR promotes the initiation and chemoresistance of ovarian cancer by activating wnt/β-catenin signaling, suggesting that HOTAIR might be a potent therapeutic target for ovarian cancer treatment.
In this study, we show that upregulation of HOTAIR induced platinum resistance in ovarian cancer, and increased HOTAIR levels were observed in recurrent platinum-resistant ovarian tumors vs primary ovarian tumors.
In conclusion, HOTAIR may be used in the development of novel treatments for ovarian cancer, particularly those that are resistant to conventional therapies.
Additionally, the results of in vitro assays showed that the suppression of HOTAIR expression in the three highly metastatic EOC cell lines (SKOV3.ip1, HO8910-PM, and HEY-A8) significantly reduced cell migration/invasion.
