Telmisartan broadly used for the treatment of hypertension that is also known for its anticancer properties. TRAIL has the potential to kill tumor cells with minimal toxicity in normal cells by binding to death receptors, DR4 and DR5. Unfortunately, these TRAIL-death receptors have failed as most human cancers are resistant to TRAIL-mediated apoptosis. In this study, we evaluated telmisartan as a novel TRAIL-DR5-targeting agent with the aim of rendering TRAIL-based cancer therapies more active. Herein, we demonstrated that telmisartan could sensitize TRAIL and enhance NSCLC tumor cell death...

Bacterial ghosts (BGs) can be generated by the controlled expression of the PhiX174 lysis gene E in gram-negative bacteria. They are intriguing vaccine candidates since ghosts retain functional antigenic cellular determinants often lost during traditional inactivation procedures. Here we prepared Edwardsiella tarda ghost (ETG) and tested different concentrations in vaccination trials. The results showed that serum IgM antibody titers were significantly higher in three different concentration immunization groups than control group (P < 0...

Benchmark dose (BMD) analysis is generally recognized superior to generate a point of departure (PoD) to conduct risk assessment on environmental toxicants, comparing with the traditionally employed no observed adverse effect level (NOAEL) or lowest observed adverse effect level (LOAEL) methods. However, only a few studies compared the two on producing PoD of thyroid toxicity caused by environmental chemicals. Here, we presented BMD analyses on several thyroid toxicity endpoints caused by a model chemical - propylthiouracil (PTU)...

Oxytocin (OT) has gained attention not only as anxiolytic drug and as potential treatment option for autistic children; it also acts as a growth and differentiation factor in neuronal cells. While behavioral effects of OT have been studied in detail, knowledge about the cellular effects of OT is relatively sparse. In this study, we present evidence for three hypotheses: 1) OT leads to neurite retraction in hypothalamic neurons via the OT receptor (OTR) 2) The transcription factor MEF-2A is a central regulator of OT-induced neurite retraction, and 3) The MAPK pathway is critical for OT-induced MEF-2A activation...

Steroid hormones play important roles in normal physiological functions and diseases. Sex steroids hormones are important in the biology and treatment of sex hormone-related cancer such as prostate cancer and breast cancer. Cells may take up steroids using multiple mechanisms. The conventionally accepted hypothesis that steroids cross cell membrane through passive diffusion has not been tested rigorously. Experimental data suggested that cells may take up sex steroid using an active uptake mechanism. 3 H-testosterone uptake by prostate cancer cells showed typical transporter-mediated uptake kinetic...

Growing evidence suggests the existence of new antibiotic resistance mechanisms. Recent studies have revealed that quorum-quenching enzymes, such as MacQ, are involved in both antibiotic resistance and cell-cell communication. Furthermore, some small bacterial regulatory RNAs, classified into RNA attenuators and small RNAs, modulate the expression of resistance genes. For example, small RNA sprX, can shape bacterial resistance to glycopeptide antibiotics via specific downregulation of protein SpoVG. Moreover, some bacterial lipocalins capture antibiotics in the extracellular space, contributing to severe multidrug resistance...

Although tamoxifen is the most frequently used drug for the treatment of estrogen receptor positive (ER+ )-breast cancer (BRCA), its efficacy varies between patients. In the present study, Cox multivariate regression of the relative mRNA expression levels in two microarray-based datasets (GSE17005 and GSE26971) was employed to develop a risk score model to evaluate the outcome of patients with BRCA in the GSE17005 dataset. A total of ten genes were used to develop the prediction model for the survival of tamoxifen-treated patients with breast cancer...

Endometriosis is a complex and heterogeneous pre-malignant inflammatory disease harboring multiple gene mutations. Previous studies have suggested that caspase recruitment domain family member (CARD)10 and CARD11 mutations may exist in endometriosis. In the present study, a collection of endometriotic lesions and paired peripheral blood from 101 patients with ovarian endometriosis were obtained, and the entire coding sequences of the CARD10 and CARD11 genes were sequenced. Evolutionary conservation analysis and online prediction programs were applied to analyze the disease-causing potential of the identified mutations...

Circulating soluble tumor necrosis factor receptor 2 (sTNFR2) has been associated with a relatively poor prognosis in various types of lymphoma. However, the specific role of TNFR2 expression in lymphoma cells remains uncharacterized. In the present study, TNFR2 expression was quantified in the Hodgkin lymphoma cell line, L428, and the anaplastic large-cell lymphoma cell line, Karpas299, using RT-PCR and western blot analyses. Karpas299 cells exhibited higher TNFR2 expression than L428 cells. Proliferation and drug resistance experiments demonstrated that Karpas299 cells also possessed a greater proliferative ability and resistance to adriamycin (ADM) than L428 cells, with 50% inhibitory concentrations (IC50 ) of 1...

Evan C Chen, Amir T Fathi, Andrew M Brunner
Despite increasing understanding of the pathobiology of acute myeloid leukemia (AML), outcomes remain dismal particularly for patients over the age of 60 years, a population enriched for therapy-related AML (tAML) and secondary AML (sAML). For decades, the standard of care for AML has been the combination of cytarabine and daunorubicin, typically delivered in combination as "7 + 3" induction. In 2017, a liposomal-encapsulated combination of daunorubicin and cytarabine (CPX-351, Vyxeos) was approved by the US Food and Drug Administration (FDA) for use in the treatment of newly diagnosed tAML or AML with myelodysplasia-related changes (AML-MRCs)...

Many renaturation projects and compensation areas are based on the use of seeds from regional indigenous wild plants, in the following: native or regional seeds. Despite this, such seeds make up only a small proportion of the total number of seeds used for greening projects - in Germany, for example, it is only around 1% (= 200 t/yr). Although the market for regional seeds is small, it is highly competitive. High-priced native seeds compete with flower mixes of unspecified origin and can only be differentiated from them by reliable quality seals...

The Papillomaviridae is a family of small, non-enveloped viruses with double-stranded DNA genomes of 5 748 to 8 607 bp. Their classification is based on pairwise nucleotide sequence identity across the L1 open reading frame. Members of the Papillomaviridae primarily infect mucosal and keratinised epithelia, and have been isolated from fish, reptiles, birds and mammals. Despite a long co-evolutionary history with their hosts, some papillomaviruses are pathogens of their natural host species. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Papillomaviridae, which is available at http://www...
