Combined treatment with and docetaxel inhibits breast cancer progression via targeting HIF-1α/VEGF mediated tumor angiogenesis in vivo.

Breast cancer is a challenging disease and leading cause of cancer death in women. There is no effective agent for metastatic breast cancer after surgery and chemotherapy. (A.

Tau nuclear translocation is a leading step in tau pathology process through P53 stabilization and nucleolar dispersion.

Tau protein abnormalities are associated with various neurodegenerative disorders, including Alzheimer's disease (AD) and traumatic brain injury (TBI). In tau-overexpressing SHSY5Y cells and iPSC-derived neuron models of frontotemporal dementia (FTD), axonal tau translocates into the nuclear compartment, resulting in neuronal dysfunction. Despite extensive research, the mechanisms by which tau translocation results in neurodegeneration remain elusive thus far.

A Comparative Study on Anticancer Effects of the and Extracts Alone and in Combination with Docetaxel on 4T1 Breast Cancer Cells.

Medicinal plants have long been studied due to their anticancer effects and use of them is commonly increased as a complementary and alternative medicine (CAM therapies) among patients with cancer. In this study, (A.m) and (A.

PRPF31 reduction causes mis-splicing of the phototransduction genes in human organotypic retinal culture.

PRPF31 is ubiquitously expressed splicing factor and has an essential role in the pre-mRNA splicing in all tissues. However, it is not clear how reduced expression of this general splicing factor leads to retinal restricted disease, retinitis pigmentosa (RP). In this study, we used RNA interference and RNA-sequencing to mimic the PRPF31 haploinsufficiency in human organotypic retinal cultures (HORCs).

Human organotypic retinal flat-mount culture (HORFC) as a model for retinitis pigmentosa11.

The splicing factor PRPF31 is the most commonly mutated general splicing factor in the retinitis pigmentosa. We used a rapid, convenient and cost effective transfection method with an efficient PRPF31 knockdown in HORFC in order to study the effect of PRPF31 downregulation on retinal gene expressions in an ex vivo model. Modified calcium phosphate method was used to transfect HORFC by PRPF31 siRNA.

Effects of extremely low-frequency pulsed electromagnetic fields on morphological and biochemical properties of human breast carcinoma cells (T47D).

This study was carried out to investigate the effects of 100 and 217 Hz extremely low-frequency pulsed electromagnetic fields (ELF-PEMF) on cell proliferation, actin reorganization, and ROS generation in a human breast carcinoma cells (T47D). Cells were exposed for 24-72 h, at 100 and 217 Hz, 0.1 mT.

COX-2 and survivin reduction may play a role in berberine-induced apoptosis in human ductal breast epithelial tumor cell line.

Berberine is an isoquinoline alkaloid that has several pharmacological effects such as antiinflammatory, antimicrobial, apoptosis-inducing and anticancer effects. It has been illustrated that the antiinflammatory effect is mediated by suppressing the nuclear factor-kappa B (NF-κB) that activates expression of some antiinflammatory and antiapoptotic proteins including cyclooxygenase-2(COX-2), inducible nitric oxide synthase (iNOS) and survivin; therefore, berberine may induce apoptosis by reducing antiinflammatory and antiapoptotic agents, which suggest the relationship between antiinflammatory and apoptosis pathways. For further illustration of the mechanism of berberine action, the human ductal breast epithelial tumor cell line (T47D cell line) was treated with different concentrations of berberine (25-100 μM/ml).

Cytotoxicity of subtoxic AgNP in human hepatoma cell line (HepG2) after long-term exposure.

Unlabelled: We aimed at evaluating the toxicity effects of low (subtoxic) concentrations of silver nanoparticles nanoparticles (AgNP, 5-10 nm) in human hepatoblastoma (HepG2) cell line after and during a period of about one month.

Methods: XTT and MTT assays were used to draw a dose-response curve; IC50 (half maximal inhibitory concentration) value of the AgNP on HepG2 cells was calculated to be 2.75-3.

Berberine-induced apoptosis via decreasing the survivin protein in K562 cell line.

Berberine is an isoquinoline alkaloid with multiple pharmacological activities, including anti-inflammatory and anti-diarrhea effect, the induction of apoptosis and anti-cancer effect. It has been reported that berberine exerts its anti-inflammatory effect via suppressing nuclear factor-kappa B (NF-κB) expression. Survivin and inducible nitric oxide synthase (iNOS) proteins may contribute to the causal relationship between anti-inflammatory and anti-apoptotic function.

Synthesis with improved yield and study on the analgesic effect of 2-hydroxyphencyclidine.

Phencyclidine (1-(1-phenylcyclohexyl)piperidine, CAS 956-90-1, PCP) has shown analgesic effects. Some of its derivatives have been synthesized and their biological properties were studied. Since a hydroxyl group has been added to the position 2 of the cyclohexane ring of PCP, this compound would be more hydrophilic than PCP.
