MicroRNA-130a regulated by HPV18 E6 promotes proliferation and invasion of cervical cancer cells by targeting TIMP2.

Human papillomaviruses (HPVs) have important roles in the development and progression of cervical cancer, but the underlying mechanisms are yet to be fully elucidated. MicroRNA-130a (miR-130a) has previously been reported to promote cervical cancer growth. However, the underlying molecular mechanisms by which miR-130a promotes cervical cancer progression have remained largely elusive.

MiR-19a negatively regulated the expression of PTEN and promoted the growth of ovarian cancer cells.

Ovarian cancer is the most lethal malignancy of the women genital tract. Exploring novel factors involved in the development of ovarian cancer and characterizing the molecular mechanisms by which regulate the tumorigenesis of ovarian cancer are quite necessary. Here, we found that miR-19a was highly expressed in ovarian cancer tissues and cell lines.

Pharmacokinetics of silybin nanoparticles in mice bearing SKOV-3 human ovarian carcinoma xenocraft.

The particle fabrication technique was used to fabricate monodisperse size and shape specific poly (lactide-co-glycolide) particles loaded with the silybin. Response surface methodology (RSM) using the central composite rotatable design (CCRD) model was used to optimize formulations of silybin nanoparticles. Further the optimized nanoparticles are characterized for particle size, zeta potential, surface morphology, entrapment efficiency, in-vitro drug release, silybin availability for tumor, plasma, lung, spleen, liver were determined.

Pretreatment Pokemon Level as a Predictor of Response to Cisplatin and Paclitaxel in Patients with Unresectable Non-Small Cell Lung Cancer.

Background: We firstly investigated the expression of Pokemon in patients with non-small cell lung cancer (NSCLC), then characterized the role of Pokemon in evaluating the response to combined cisplatin and paclitaxel chemotherapy and prognosis.

Patients And Methods: In this study, 61 patients with previously untreated locally advanced or metastatic NSCLC were treated with a combination chemotherapy comprising cisplatin and paclitaxel. The correlation between serum expression of Pokemon and effectiveness of chemotherapy was assessed.

Effect of downregulated histone deacetylase 2 expression on cell proliferation and cell cycle in cervical cancer.

Purpose: To investigate the effects and molecular mechanism of downregulated histone deacetylase 2 (HDAC2) expression on cell proliferation and cell cycle in cervical cancer Hela cells.

Methods: HDAC2 small interfering (si)RNA and control siRNA were transfected into cervical cancer Hela cells. A cell proliferation assay using a cell counting kit-8 was applied to analyze the change in cell proliferation before and after transfection.

[Pregnancy outcomes of day-2 versus day-3 embryo transfer in poor responders].

Objective: To investigate whether the day of embryo transfer (day 2 or day 3) affects clinical pregnancy outcomes in poor responder patients.

Methods: We retrospectively analyzed the pregnancy rates of 265 initial fresh cycles of in vitro fertilization-embryo transfer (IVF-ET), all transferred on day 2 (n = 169) or day 3 (n = 96) irrespective of quality because of an extremely low number of available embryos.

Results: Among the poor responders aged < 35 years, a higher rate of clinical pregnancy was achieved in the day-3 than in the day-2 group (50% vs 32.

Depletion of Pokemon gene inhibits hepatocellular carcinoma cell growth through inhibition of H-ras.

Background: Pokemon is a transcription repressor which plays a critical role in cell transformation and malignancy. However, little is known about its effect on the development and progression of hepatocellular carcinoma (HCC). The aim of this study was to investigate the expression of Pokemon in human HCC tissues and the biological behavior of Pokemon in HCC cells in which it is overexpressed.

[Hypoxia induces heat shock protein HSP70-2 expression in a HIF-1 dependent manner].

Objectives: To investigate role of hypoxia inducible factor 1 (HIF-1) in the transcriptional activation of heat shock protein 70-2 (HSP70-2) in hepatocellular carcinoma (HCC) cells under hypoxic conditions.

Methods: HCC cells were exposed to reduced oxygen atmosphere (1% O2), or treated with YC-1 or HIF-1 alpha siRNA, the expression of HIF-1 alpha and HSP70-2 were detected by Western blot analysis. Serial deletions of the HSPA2 promoter were cloned in the reporter pGL3-Basic plasmid.
