Objective: To explore the inhibitory effects of silencing long non-coding RNA (LncRNA) HIF1A-AS2 on epithelialmesenchymal transition (EMT) and tumor stem cell-like phenotype in cervical cancer cells.
Methods: We designed 3 shRNA constructs for silencing HIF1A-AS2 in CaSki cells, and the shRNA with the strongest interference effect was selected for subsequent experiment. CaSki cells were transfected with shRNA-NC or Sh-HIF1A-AS2, and the changes in cell viability, invasion ability, EMT, expressions of EMT-related proteins, formation of cell spheres and expressions of stem cell markers were detected.
Results: Transfection with shRNA-NC and Sh-HIF1A-AS2 did not significantly affected the viability of CaSki cells ( > 0.05). Compared with the cells transfected with shRNA-NC, the cells transfected with Sh- HIF1A-AS2 showed significantly reduced invasion ability, expressions of vimentin N-cadherin, and cell sphere formation ability. HIF1A-AS2 silencing obviously lowered the rate of ABCG2-positive cells, significantly reduced the mRNA and protein expressions of Nanog, OCT4, and SOX2, and strongly enhanced the expression of E-cadherin in CaSki cells ( < 0.05).
Conclusions: Silencing HIF1A-AS2 can inhibit proliferation, invasion and migration of cervical cancer cells .

Increased expression of lnc-FANCI-2, a newly discovered long noncoding RNA, is associated with cervical lesion progression from cervical intraepithelial neoplasia stage 1 (CIN1, low grade), CIN2-3 (high grade), to cervical cancer. Viral oncoprotein E7 of high-risk human papillomaviruses (HR-HPVs) and host transcription factor YY1 are two major factors promoting lnc-FANCI-2 expression. Using CRISPR-Cas9 technology, we knocked out the expression of in the HPV16-positive cervical cancer cell line, CaSki cells.

In this research study, we introduce a novel approach to develop an innovative nanocarrier system comprising gold nanoparticles (GNPs) loaded with doxorubicin (D) in combination with natural molecules, such as trans-resveratrol (R), piperine (P), and icariin (Ic), against human cervical cancer. The final objective is to improve the anticancer efficacy of doxorubicin on HeLa and CaSki cell lines. Resveratrol was also used for the synthesis of GNP_R1 nanoparticles.

Objective: The aim of this study is to evaluate the influence of altered expression of indoleamine 2,3-dioxygenase 1 (IDO1) on key enzymes and metabolites within the tryptophan-kynurenine pathway, as well as to assess the resulting effects on the malignant biological behavior of cervical cancer cells, including proliferation, invasion and migration.
Methods: IDO1 expression was assessed in cervical cancer and normal cervical tissues via immunohistochemistry and western blot (WB) analysis. Four human cervical cancer cell lines (HeLa, C33A, SiHa, CaSki) were cultured, and HeLa and SiHa cells-characterized by elevated IDO1 expression-were selected for further experimentation.

This study evaluated the probiotic potential of Probio87 (Probio87), focusing on its physiological robustness, safety, antimicrobial properties, and anticancer activity, with relevance to vaginal and cervical health. Tests included acid and bile salt tolerance, mucin adhesion, and carbohydrate utilization. Prebiotic preferences were assessed using FOS, GOS, and inulin.
