The pathological presence of tissue factor (TF) in cancer cells promotes tumor-initiated thrombosis and cancer metastasis. We found that TF is aberrantly present in large percentage of aggressive triple negative breast cancer (TNBC) and pancreatic adenocarcinoma (PaC), two most lethal forms of malignancy that urgently need effective treatment. TF expression in TNBC clustered with higher levels of vimentin, basal-type keratins KRT5/14 and caveolin-1 but lower levels of luminal-type biomarkers. We developed a novel and specific anti-TF therapeutic antibody SC1, which displayed an exceedingly high potency against TF extracellular domain (EC50: 0...

Pseudogenes are initially regarded as non-functional genomic fossils resulted from inactivating gene mutations during evolution. Far from being silent, pseudogenes are proved to regulate the expression of protein-coding genes through function as microRNA sponge in vivo. The aim of our study was to propose an integrative systems biology approach to identify disease pseudogenes base on competitive endogenous RNA (ceRNA) hypothesis. Here, we applied our method to lung adenocarcinoma (LUAD) RNASeq data from TCGA and identified 33 candidate pseudogenes...

Abdikarim Abdullahi, Marc G Jeschke
In this era of increased obesity and diabetes prevalence, the browning of white adipose tissue (WAT) has emerged as a promising therapeutic target to induce weight loss and improve insulin sensitivity in this population. The browning process entails a shift in the WAT from primarily storing excess energy to the dissipation of energy as heat. However, this idealistic view of WAT browning being the saviour of the metabolic syndrome has been criticized by studies in burns and cancer patients that have shown browning to be detrimental rather than being beneficial...

OBJECTIVE: To evaluate the predictive value of Type D personality on in-stent restenosis (ISR) rates at 1- and 2-year post percutaneous coronary intervention (PCI) in patients with coronary artery disease (CAD). METHODS: Consecutive patients with CAD who underwent PCI for drug-eluting stents (DES) (n=173) completed the Type D Scale-14 (DS14) at baseline. Follow-up coronary angiographic evaluation was routinely planned at 1- and 2-years after the procedure. RESULTS: Follow-up coronary angiography was performed in 159 and 112 patients at 1- and 2-years post-PCI, respectively...

Epidermal Growth Factor Receptor (EGFR) is a potential drug target in cancer therapy. Missense mutations play major roles in influencing the protein function, leading to abnormal cell proliferation and tumorigenesis. A number of EGFR inhibitor molecules targeting ATP binding domain were developed for the past two decades. Unfortunately, they become inactive due to resistance caused by new mutations in patients, and previous studies have also reported noticeable differences in inhibitor binding to distinct known driver mutants as well...

Artemin (ARTN) is a member of glial cell line-derived neurotrophic factor (GDNF) family of ligands, and its signaling is mediated via a multi-component receptor complex including the glycosylphosphatidylinositol-anchored GDNF family receptors a (GFRa1, GFRa3) and RET receptor tyrosine kinase. The major mechanism of ARTN action is via binding to a non-signaling co-receptor. The major function of ARTN is to drive the molecule to induce migration and axonal projection from sympathetic neurons. It also promotes the survival, proliferation and neurite outgrowth of sympathetic neurons in vitro...

O Hayden Griffin, Megan E Webb
Kratom is a traditional drug from Southeast Asia that has been an emerging new substance in the United States. On August 30, 2016, the DEA announced the intention to emergency schedule kratom into Schedule I. To support this decision, the DEA cited an increase in drug seizures of kratom and an increase in calls to poison control concerning kratom. However, a short time later, on October 12, 2016, the DEA withdrew the intent to schedule kratom after public and congressional backlash. The withdrawal by the DEA was somewhat unprecedented...

Ecstasy (MDMA) has regained popularity in powder and crystalline form, known as Molly. However, it is unknown whether all Molly users are aware that Molly is ecstasy. A total of 1045 nightclub/festival-attending adults in New York City were surveyed about ecstasy/MDMA/Molly use in 2016. Users were asked if they agreed that "Molly is (or is supposed to be) ecstasy/MDMA." Of the 43.5% reporting lifetime use, 84.6% agreed that Molly is ecstasy, 9.5% disagreed, and 5.9% reported not knowing that Molly is ecstasy...

The world widespread rise in cancer incidence has caused an increase in the demand for effective and safe materials for treatment. One of the most prevalent forms of treatment for cancer is photodynamic therapy (PDT), which is seen as an alternative to radiotherapy, as well as chemotherapy. In more recent years, researchers are exploring new nanotechnology-based strategies to improve the effectiveness of PDT. OBJECTIVE: The objective of this review is to explore the current trends and research findings associated with PDT and the development of nanotechnology as treatment modality for cancer...

Recombinant protein-polymer scaffolds such as Elastin-Like Polypeptides (ELPs) offer drug delivery opportunities including biocompatibility, monodispersity, and multi-functionality. We recently reported that fusion of FK-506 binding protein 12 (FKBP) to an ELP nanoparticle (FSI) increases rapamycin (Rapa) solubility, suppresses growth of breast cancer xenografts, and reduces side-effects observed with free drug controls. This new report significantly advances this carrier strategy by demonstrating the co-assembly of two different ELP diblock copolymers containing drug-loading and tumor-targeting domains...

Prostate cancer patients have been suffering from limited treatment options due to late diagnosis, poor drug tolerance, and multi-drug resistance to almost all the current drug treatments. Therefore, it is important to seek a new alternative therapeutic medicine that can effectively prevent the disease and even eradicate the progression and metastasis of prostate cancer. Vernonia amygdalina Delile (VAD) is a common edible vegetable in Cameroon that has been used as a traditional medicine for some human diseases...

Synthetic polymers offer tunable platforms to create new oral drug delivery vehicles (excipients) to increase solubility, supersaturation maintenance, and bioavailability of poorly aqueous soluble pharmaceutical candidates. Five well-defined diblock terpolymers were synthesized via reversible addition-fragmentation chain transfer polymerization (RAFT) and consist of a first block of either poly(ethylene-alt-propylene) (PEP), poly(N-isopropylacrylamide) (PNIPAm), or poly(N,N-diethylaminoethyl methacrylate) (PDEAEMA) and a second hydrophilic block consisting of a gradient copolymer of N,N-dimethylacrylamide (DMA) and 2-methacrylamidotrehalose (MAT)...

Hepatitis C virus (HCV) is a significant problem among hemodialysis population, especially in India where renal transplant often gets delayed in the presence of live-related donors. An acceleration of liver cirrhosis and poor renal allograft outcomes are often witnessed in allograft recipients with high viral load. Use of interferon in the postrenal transplant setting for the treatment of hepatitis C viral infection was limited to a few grave situations, fearing the precipitation of allograft rejection and poor efficacy for sustained virological remission...

Falsified medicines are a raising problem for the German drug market. The complex distribution channels across the European market facilitates the introduction of falsified and stolen medicines into the legal supply chain and may pose a risk for patients. The "Herceptin® case" from 2014 of falsified medicines of Italian origin demonstrates how complex distribution systems have been misused by criminal organizations in order to introduce stolen and thus falsified medicines via the parallel trade into the market, and which measures the authorities and the parallel-traders in the national and European network have taken to ensure patient safety...

Hepatocarcinogenesis is a multistep process, heralded by abnormalities in cell differentiation and proliferation and sustained by an aberrant neoangiogenesis. Understanding the underlying molecular pathogenesis leading to hepatocellular carcinoma is a prerequisite to develop new drugs that will hamper or block the steps of these pathways. As hepatocellular carcinoma has higher arterial vascularization than normal liver, this could be a good target for novel molecular therapies. Introduction of the antiangiogenic drug sorafenib into clinical practice since 2008 has led to new perspectives in the management of this tumor...
