Alzheimer's disease (AD) is a devastating neurodegenerative disease and there is no effective therapy for it. Peroxisome proliferators activated receptor-gamma (PPAR-γ) agonists is a promising therapeutic approach for AD and has been widely studied recently, but no consensus was available up to now. To clarify this point, a meta-analysis was performed. We searched MEDLINE, EMBASE, Cochrane Central database, PUBMED, Springer Link database, SDOS database, CBM, CNKI and Wan fang database by December 2014. Standardized mean difference (SMD), relative risk (RR) and 95% confidence interval (CI) were calculated to assess the strength of the novel therapeutics for AD and mild-to-moderate AD. A total of nine studies comprising 1314 patients and 1311 controls were included in the final meta-analysis. We found the effect of PPAR-γ agonists on Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-cog) scores by using STATA software. There was no evidence for obvious publication bias in the overall meta-analysis. There is insufficient evidence of statistically incognition of AD and mild-to-moderate AD patients have been improved who were treated with PPAR-γ agonists in our research. However, PPAR-γ agonists may be a promising therapeutic approach in future, especially pioglitazone, with large-scale randomized controlled trials to confirm. Copyright © 2015 Taylor and Francis.

As the major barrier to curative cancer chemotherapy, chemoresistance presents a formidable challenge to both cancer researchers and clinicians. We have previously shown that the bladder cancer (BCa) cell line 5637 is significantly more sensitive to the cytoxicity of five chemotherapeutic agents than H-bc cells. Using an RNA-seqbased omic analysis and validation at both the mRNA and protein levels, we found that the inhibitor of growth 5 (ING5) gene was upregulated in 5637 cells compared with H-bc cells, indicating that it has an inhibitory role in BCa chemoresistance. siRNAmediated inhibition of ING5 increased the chemoresistance and inhibited the DNA damage response pathway in 5637 cells. Conversely, forced expression of EGFP-ING5 decreased the chemoresistance of and activated the DNA damage response pathway in H-bc cells. We also showed that ING5 gene expression is inhibited by miR-193a- 3p and is instrumental in miR-193a-3p's role in activating BCa chemoresistance. Our results demonstrate both the role and mechanism of inhibition of BCa chemoresistance by ING5.

The purpose of this study was to investigate the overall incidence and relative risk (RR) of hemorrhagic events in cancer patients treated with ramucirumab. 298 potentially relevant citations on ramucirumab from Pubmed, Web of Science and the Cochrane Database, as well as abstracts presented at conferences (all up to March 2016) were identified through our initial search. Only phase II and III prospective clinical trials of ramucirumab among cancer patients with toxicity records on hemorrhagic events were selected for final analysis. Data was extracted from the original studies by two independent reviewers. The overall incidence, RR, and 95% confidence intervals (CI) were calculated using fixed or random effects models according to the heterogeneity of the enrolled studies. The statistical analysis was performed by STATA version 11.0 (Stata Corporation, College Station, TX). 4963 patients with a variety of solid tumors from eleven eligible studies were selected into our analysis. The results demonstrated that the overall incidences of all-grade and high-grade hemorrhagic events in cancer patients were 27.6% (95% CI, 18.7-36.5%) and 2.3% (95% CI, 1.3-3.2%), respectively. The RR of hemorrhagic events of ramucirumab compared to control was significantly increased for low-grade (RR, 2.06; 95% CI, 1.85-2.29, p < 0.001), but not for high-grade (RR, 1.19, 95% CI, 0.80-1.76, p=0.39) hemorrhagic events. Hemorrhagic events associated with ramucirumab are modest and manageable while patients could continue to receive ramucizumab treatment to achieve their maximum clinical benefits.

Alantolactone is the active ingredient in frankincense, and is extracted from the dry root of elecampane. It has a wide variety of uses, including as an insect repellent, antibacterial, antidiuretic, analgesic and anticancer agent. In addition, alantolactone induces apoptosis of human cervical cancer cells, however, its mechanism of action remains to be elucidated. Therefore, the present study investigated whether alantolactone was able to induce apoptosis of human cervical cancer cells, and its potential mechanisms of action were analyzed. Treatment of HeLa cells with alantolactone (0, 10, 20, 30, 40, 50 and 60 μM) for 12 h significantly inhibited growth in a dose-dependent manner. Cells treated with 30 μM of alantolactone for 0, 3, 6 and 12 h demonstrated marked induction of apoptosis in a time-dependent manner. Treatment of HeLa cells with 30 μM of alantolactone for 0, 3, 6 and 12 h significantly induced the generation of reactive oxygen species (ROS) and inhibited glutathione (GSH) production in HeLa cells in a dose-dependent manner. Alantolactone additionally markedly inhibited the Bcl-2/Bax signaling pathway in HeLa cells. Therefore, administration of alantolactone induced apoptosis of human cervical cancer cells via ROS generation, GSH depletion and inhibition of the Bcl-2/Bax signaling pathway. © 2016, Spandidos Publications.

Small cell lung cancer (SCLC) is one of the most aggressive types of cancer, yet the pathologic mechanisms underlying its devastating clinical outcome remain elusive. In this report, we surveyed 924 miRNA (miR) for their expressions in the formalin-fixed paraffin-embedded specimens from 42 patients with SCLC, and found that the downregulated miR-886-3p is closely correlated with the shorter survival of SCLC. This correlation was validated with another 40 cases. It was further discovered that loss of miR-886-3p expression was mediated by DNA hypermethylation of its promoter in both cultured SCLC cells and tumor samples. Moreover, miR-886-3p potently repressed cell proliferation, migration, and invasion of NCI-H446 cell in cell culture via suppression of the expression of its target genes: PLK1 and TGF-β1 at posttranscription levels. Forced upregulation of miR-886-3p greatly inhibited in vivo tumor growth, bone/muscle invasion, and lung metastasis of NCI-H446 cells. This newly identified miR-886-3p-PLK1/TGF-β1 nexus that modulates SCLC aggression suggests that both loss of miR-886- 3p expression and hypermethylation of the miR-886 promoter are the promising indicators for poor outcome of as well as new therapeutic targets for SCLC. © 2013 American Association for Cancer Research.

MicroRNAs have been identified as key players in the development and progression of osteosarcoma, which is the most common primary malignancy of bone. Sequencing-based miR-omic and quantitative real-time PCR analyses suggested that the expression of miR-193a-3p and miR-193a-5p was decreased by DNA methylation at their promoter region in a highly metastatic osteosarcoma cell line (MG63.2) relative to their expression in the less metastatic MG63 cell line. Further wound-healing and invasion assays demonstrated that both miR-193a-3p and miR-193a-5p suppressed osteosarcoma cell migration and invasion. Moreover, introducing miR-193a-3p and miR-193a-5p mimics into MG63.2 cells or antagomiRs into MG63 cells confirmed their critical roles in osteosarcoma metastasis. Additionally, bioinformatics prediction along with biochemical assay results clearly suggested that the secretory small GTPase Rab27B and serine racemase (SRR) were direct targets of miR-193a-3p and miR-193a-5p, respectively. These two targets are indeed involved in the miR-193a-3p- and miR-193a-5p-induced suppression of osteosarcoma cell migration and invasion. MiR-193a-3p and miR-193a-5p play important roles in osteosarcoma metastasis through down-regulation of the Rab27B and SRR genes and therefore may serve as useful biomarkers for the diagnosis of osteosarcoma and as potential candidates for the treatment of metastatic osteosarcoma.

Micro RNA (miR)-486-5p is often aberrantly expressed in human cancers. The aim of this study was to identify the prognostic value of miR-486-5p expression in digestive system cancers. Tissue microarrays were constructed with 680 samples including 185 esophageal squamous cell carcinomas (ESCCs), 90 gastric adenocarcinomas (GCs), and 60 digestive system cancer tissues from 10 ESCC, 10 GC, 10 colon, 10 rectum, 10 liver, 10 pancreatic cancer, and corresponding normal tissues. Twenty normal digestive system mucosa tissues from healthy volunteers were included as normal controls. In GC, miR-486-5p expression was decreased in 62.8% of cases (59/94), increased in 33.0% (31/94), and unchanged in 4.2% (4/94); in ESCC its expression was decreased in 66.2% (129/195), increased in 32.3% (63/195), and unchanged in 1.5% (3/195). Expression of miR-486-5p was decreased in 12, and increased in 8, of 20 cases of colon or rectum cancer; decreased in 6, and increased in 4, of 10 cases of liver cancer; and decreased in 8, and increased in 2, of 10 cases of pancreatic cancer. Multivariate and univariate regression analysis demonstrated that low/unchanged miR-486-5p predicted poor prognosis in ESCC (hazard ratio [HR], 4.32; 95% confidence interval [CI], 2.62-7.14; P < 0.001; HR, 3.88; 95% CI, 2.43-6.22; P < 0.001, respectively) and GC (HR, 2.46; 95% CI, 1.35-4.50; P = 0.003; HR, 2.55; 95% CI, 1.39-4.69; P = 0.002, respectively). MiR-486-5p might therefore be an independent tumor marker for evaluating prognosis in patients with ESCC or GC.

Radiation therapy is one of the most important methods of contemporary cancer treatment. Cells in the G2 and M phases are more sensitive to radiation therapy, and cell division cycle 25 homolog C (CDC25C) is essential in shifting the cell cycle between these two phases. In this study, the knockdown of CDC25C in human esophageal squamous carcinoma EC9706 cells was mediated by transfecting shRNA against human CDC25C-subcloning into pGV248. The levels of CDC25C mRNA and protein expression were assessed by reverse transcription-polymerase chain reaction (RT-PCR) and western blotting, respectively. Moreover, cell proliferation and radiosensitivity were measured. Stable CDC25C-knockdown EC9706 cell lines were successfully established. Furthermore, the proliferation of both control and CDC25C-shRNA-EC9706 cells was inhibited after the cells were treated with increasing X-ray doses, and the proliferation of the control cells was affected more significantly (p<0.05). Moreover, cell colony formation assays allowed us to reach the same conclusion. Taken together, our experiments demonstrated that the knockdown of CDC25C can reduce both the radiotherapy sensitivity and the proliferation activity of EC9706 cells. Thus, CDC25C might be a potential biomarker for radiotherapy treatment.
