Objective: To evaluate the effect of exogenous wild PTEN gene stable transfected into human ovarian cancer cell line HO-8910 on phosphatidyl inositol 3-kinase (PI3K)/protein kinase B (Akt) signal pathway and cells proliferation.
Methods: Wild-type PTEN recombinant eukaryotic expression plasmid was constructed and then was transfected into HO-8910 cells by lipofectamine 2000. The expression of PTEN, Akt1, Akt2, PI3K mRNA and protein of PTEN were tested by reverse transcription (RT)-PCR and Western blot. The proliferation of HO-8910 after wild PTEN gene transfected was measured by methyl thiazolyl tetrazolium (MTT).
Results: Wild-type PTEN gene was successfully transfected into HO-8910 cells. The results of RT-PCR and western bolt showed that there were the significant expression high level of PTEN mRNA and protein after infected by wild-PTEN plasmid than those in the control [(17,372 ± 23) vs. (39 ± 1) vs. (78 ± 4) copies/ml, P < 0.05]. While the expression of mRNA of Akt1, Akt2 and PI3K were decreased clearly than those in the control [(28 ± 2) vs. (115 ± 5), (7 ± 1) vs. (18 ± 2), (61 ± 2) vs. (84 ± 2) copies/ml, all P < 0.05]. The proliferation rate of HO-8910 cells was obviously slower than those in the control (90 158 ± 47 vs. 148,251 ± 65 vs. 250,115 ± 62, P < 0.05).
Conclusion: Transfection of PTEN may increase the expression of PTEN and inhibit the proliferation of HO-8910 cells, in which PI3K/Akt signal pathway is inhibit significantly.

Background: Mitochondrial dysregulation contributes to the chemoresistance of multiple cancer types. Yet, the functions of mitochondrial dysregulation in Ovarian serous cystadenocarcinoma (OSC) remain largely unknown.
Aim: We sought to investigate the function of mitochondrial dysregulation in OSC from the bioinformatics perspective.

Accurately visualizing the intracellular trafficking of upconversion nanoparticles (UCNPs) loaded with phthalocyanines and achieving precise photodynamic therapy (PDT) using near-infrared (NIR) laser irradiation still present challenges. In this study, a novel NIR laser-triggered upconversion luminescence (UCL) imaging-guided nanoparticle called FA@TPA-NH-ZnPc@UCNPs (FTU) was developed for PDT. FTU consisted of UCNPs, folic acid (FA), and triphenylamino-phenylaniline zinc phthalocyanine (TPA-NH-ZnPc).

A new 14-membered resorcylic acid lactone (RAL), chaetolactone A (), along with three known ones (-), was obtained from the fermentation of the soil-derived fungus SSJZ001. Their structures were established based on extensive spectroscopic data analyses (UV, IR, HRESIMS, 1D, and 2D NMR),C NMR chemical shifts calculations coupled with the DP4 probability method, theoretical calculations of ECD spectra, as well as X-ray diffraction analysis. All compounds were evaluated for their cytotoxic effects against A549, HO-8910, and MCF-7 cell lines.

Background: Eukaryotic Initiation Factor 3C (EIF3C) represents a pivotal translational initiation factor in eukaryotes and has been shown to facilitate the progression of various neoplasms. However, its mechanistic role in ovarian cancer remains elusive.
Methods: In this research, the expression of EIF3C in ovarian cancer tissues was investigated using immunohistochemistry.
