A pH-sensitive molecular switch able to change its conformation upon protonation at endosomal pH values is embedded into the structure of cationic lipidoid materials, thus conferring endosomal escape properties. Involvement of the conformational switch in the endosomal escape process was confirmed and leading material identified was able to induce efficient gene knockdown both in vitro and in vivo. The lipid nanoparticles reported here are promising for therapeutic applications and this work could serve as a template for future design of stimulus-responsive (ionic, redox, light) molecular switch for drug and gene delivery...

Late stage epithelial ovarian cancer has a dismal prognosis. Identification of pharmacogenomic markers (i.e. polymorphisms) to stratify patients to optimize individual therapy is of paramount importance. We here report the retrospective analysis of polymorphisms in 5 genes (ATM, ATR, Chk1, Chk2 and CDK12) involved in the cellular response to platinum in a cohort of 240 cancer patients with late stage ovarian cancer. The aim of the present study was to evaluate associations between the above mentioned SNPs and patients' clinical outcomes: overall survival (OS) and progression free survival (PFS)...

Spinal manipulative therapy (SMT) creates health benefits for some while for others, no benefit or even adverse events. Understanding these differential responses is important to optimize patient care and safety. Toward this, characterizing how loads created by SMT relate to those created by typical motions is fundamental. Using robotic testing, it is now possible to make these comparisons to determine if SMT generates unique loading scenarios. In 12 porcine cadavers, SMT and passive motions were applied to the L3/L4 segment and the resulting kinematics tracked...

The human metastasis associated lung adenocarcinoma transcript 1 (MALAT1) is a long non-coding RNA associated with metastasis, and is a favorable prognostic factor for lung cancer. Recent studies have shown that MALAT1 plays an important role in many malignancies. However, little is known about the role of MALAT1 in glioma. In this study, we determined the expression of MALAT1 and explored its prognostic value in glioma. Further, we investigated the regulatory mechanism of MALAT1 in glioma progression. Our results showed that the expression of MALAT1 was significantly decreased in glioma specimens than in noncancerous brain tissues...

There is debate in the tobacco control literature about the value of a medical model in reducing smoking-related harm. The variety of medical treatments for smoking cessation has increased, health professionals are encouraged to use them to assist smoking cessation and tobacco dependence is being described as a 'chronic disease'. Some critics suggest that the medicalisation of smoking undermines the tobacco industry's responsibility for the harms of smoking. Others worry that it will lead smokers to deny personal responsibility for cessation, create beliefs in 'magic bullets' for smoking cessation, or erode smokers' confidence in their ability to quit...

Radioresistance remains a significant obstacle in the treatment of Prostate Cancer (PCa). To simulate the clinical scenario of irradiation resistance (IRR), we created DU145-IRR PCa cell lines by treatment with 2 Gy daily IR for 59 fractions. DU145-IRR cells acquired an aggressive phenotype as evidenced by increased clonogenic survival, tumorigenic potential and invasiveness. We performed transcriptome profiling to discover dysregulated genes in DU145-IRR cells and identified the long non-coding RNA (lncRNA), Urothelial carcinoma-associated 1 (UCA1)...

Knowledge on the molecular mechanisms underlying metastasis colonization in Non-Small Cell Lung Cancer (NSCLC) remains incomplete. A complete overview integrating driver mutations, primary tumour heterogeneity and overt metastasis lacks the dynamic contribution of disseminating metastatic cells due to the inaccessibility to the molecular profiling of Circulating Tumour Cells (CTCs). By combining immunoisolation and whole genome amplification, we performed a global gene expression analysis of EpCAM positive CTCs from advanced NSCLC patients...
