In Vitro and In Vivo Antitumor Efficacy of Celluclast Extract against Bladder Cancer.

Various physiological benefits have been linked to (HF), an edible brown seaweed. Here, fucose-containing sulfated polysaccharides were extracted from celluclast-processed HF (SPHF) and their antitumor efficacy against bladder cancer was evaluated in vitro and in vivo. SPHF possesses high sulfated polysaccharide and fucose contents and free radical scavenging activities compared to those of celluclast-processed HF extracts (CHF).

Pre-implantation genetic diagnosis and pre-implantation genetic screening: two years experience at a single center.

Objective: Indications for preimplantation genetic diagnosis (PGD)/preimplantation genetic screening (PGS) cycles and clinical outcomes were evaluated at CHA Gangnam Medical Center.

Methods: This is retrospective cohort study. All patients (n=336) who went through fertilization (IVF)-PGD/PGS cycles (n=486) between January 2014 and December 2015 were included in Fertility Center of CHA Gangnam Medical Center.

Morin Inhibits Proliferation, Migration, and Invasion of Bladder Cancer EJ Cells via Modulation of Signaling Pathways, Cell Cycle Regulators, and Transcription Factor-Mediated MMP-9 Expression.

Preclinical Research Previous studies have shown that morin exerts diverse pharmacological activities. In this study, we investigated the inhibitory activity of morin on bladder cancer EJ cells. Morin significantly inhibited EJ cell proliferation, which was related to the G1-phase cell cycle arrest together with the reduced expression of cyclin D1, cyclin E, CDK2, and CDK4 via increased expression of p21WAF1.

Rosa hybrida extract suppresses vascular smooth muscle cell responses by the targeting of signaling pathways, cell cycle regulation and matrix metalloproteinase-9 expression.

The pharmacological effects of Rosa hybrida are well known in the cosmetics industry. However, the role of Rosa hybrida in cardiovascular biology had not previously been investigated, to the best of our knowledge. The aim of the present study was to elucidate the effect of water extract of Rosa hybrida (WERH) on platelet‑derived growth factor (PDGF)-stimulated vascular smooth muscle cells (VSMCs).

Esculetin Inhibits VEGF-Induced Angiogenesis Both In Vitro and In Vivo.

Esculetin is known to inhibit tumor growth, but its effect in angiogenesis has not been studied. Here, we report the efficacy of esculetin on VEGF-induced angiogenesis. Esculetin treatment inhibited VEGF-induced proliferation and DNA synthesis of HUVECs with no cell toxicity.

Inhibitory effects of fermented extract of Ophiopogon japonicas on thrombin-induced vascular smooth muscle cells.

Ophiopogon japonicus is known to have various pharmacological effects. The present study investigated the effects of an extract of fermented Ophiopogon japonicas (FEOJ) on thrombin‑treated vascular smooth muscle cells (VSMCs). FEOJ treatment inhibited the proliferation of VSMCs treated with thrombin as indicated by an MTT assay.

MicroRNA-20b inhibits the proliferation, migration and invasion of bladder cancer EJ cells via the targeting of cell cycle regulation and Sp-1-mediated MMP-2 expression.

MicroRNAs (miRs) serve either as oncogenes or tumor-suppressor genes in tumor progression. MicroRNA-20b (miR‑20b) is known to be involved with the oncomirs of several types of cancers. However, in the present study we describe how miR-20b inhibits the proliferation, migration and invasion of bladder cancer EJ cells.

EPO gene expression promotes proliferation, migration and invasion via the p38MAPK/AP-1/MMP-9 pathway by p21WAF1 expression in vascular smooth muscle cells.

The use of recombinant human erythropoietin (rHuEpo) can lead to hypertrophy and hyperplasia, and has induced the proliferation of vascular smooth muscle cells (VSMCs). The effect of the EPO gene in the migration and invasion of VSMCs remains unclear. In this study, overexpression of the EPO gene increased the DNA synthesis and phosphorylation of ERK1/2 and p38MAPK in VSMCs.

EPO gene expression induces the proliferation, migration and invasion of bladder cancer cells through the p21WAF1‑mediated ERK1/2/NF-κB/MMP-9 pathway.

Erythropoietin (EPO) is a cytokine that modulates the production of red blood cells. Previous studies have contradicted the assumed role of EPO in tumor cell proliferation. In the present study, we investigated the effect of EPO in the proliferation, migration and invasion that is involved in the signaling pathways and cell-cycle regulation of bladder cancer 5637 cells.
