Conventional treatment planning in intensity-modulated radiation therapy (IMRT) is a trial-and-error process that usually involves tedious tweaking of optimization parameters. Here, we present an algorithm that automates part of this process, in particular the adaptation of voxel-based penalties within normal tissue. Thereby, the proposed algorithm explicitly considers a priori known physical limitations of photon irradiation. The efficacy of the developed algorithm is assessed during treatment planning studies comprising 16 prostate and 5 head and neck cases...

Behçet's disease (BD) is a multi-systemic inflammatory disorder consisting of recurrent oral aphthosis, genital ulcers, and chronic relapsing bilateral uveitis; however, many other organs may be affected. Several pro-inflammatory cytokines, mainly derived from Th1 and Th17 lymphocytes, seem to be involved in different pathogenic pathways leading to development of the clinical manifestations. On this basis, the primary aim of our study was to compare a core set of pro-inflammatory cytokines between patients with BD and healthy control (HC)...

Transcriptional reprogramming of macrophages upon Mycobacterium tuberculosis (Mtb) infection is widely studied; however, the significance of alternate splicing (AS) in shaping cellular responses to mycobacterial infections is not yet appreciated. Alternate splicing can influence transcript stability or structure, function and localization of corresponding proteins thereby altering protein stoichiometry and physiological consequences. Using comprehensive analysis of a time-series RNA-seq data obtained from human macrophages infected with virulent or avirulent strains of Mtb, we show extensive remodeling of alternate splicing in macrophage transcriptome...

Exosomal-miRNAs are emerging as mediators of crosstalk between tumor cells and macrophages. In this study, we observed that exosomes derived from TWEAK-stimulated macrophages (TMs) could be internalized by epithelial ovarian cancer (EOC) cells and inhibit cell metastasis. Through a miRNA microarray analysis, we identified 19 miRNAs that are differentially expressed in exosomes derived from macrophages treated with or without TWEAK. The study validated that TWEAK not only increased the levels of microRNA-7 (miR-7) in macrophages and its secreted exosomes but also resulted in an elevated level of miR-7 in recipient EOC cells, which eventually reduced the activity of the EGFR/AKT/ERK1/2 pathway...

Common variable immunodeficiency (CVID) is the largest group of symptomatic primary immune deficiencies; it is characterized by hypogammaglobulinemia, poor response to vaccines and increased susceptibility to infections. Cellular phenotypes and abnormalities have been described both in adaptive and innate immune response. Several classifications of common variable immunodeficiency are based on defects found on T and B cells, which have been correlated with clinical manifestations. In recent years, significant progress has been made in elucidating the genetic mechanisms that result in a IDCV phenotype...

BACKGROUND: Dietary intake of saturated fat is a likely contributor to nonalcoholic fatty liver disease (NAFLD) and insulin resistance, but the mechanisms that initiate these abnormalities in humans remain unclear. We examined the effects of a single oral saturated fat load on insulin sensitivity, hepatic glucose metabolism, and lipid metabolism in humans. Similarly, initiating mechanisms were examined after an equivalent challenge in mice. METHODS: Fourteen lean, healthy individuals randomly received either palm oil (PO) or vehicle (VCL)...

Beyond the natural proteome, high-throughput mutagenesis offers the protein engineer an opportunity to "tweak" the wild-type activity of a protein to create a recombinant protein with required attributes. Of the various approaches available, saturation mutagenesis is one of the core techniques employed by protein engineers, and in recent times, nondegenerate saturation mutagenesis is emerging as the approach of choice. This review compares the current methodologies available for conducting nondegenerate saturation mutagenesis with traditional, degenerate saturation and briefly outlines the options available for screening the resulting libraries, to discover a novel protein with the required activity and/or specificity...

The survival of patients diagnosed with glioblastoma (GBM), the most deadly form of brain cancer, is compromised by the proclivity for local invasion into the surrounding normal brain, which prevents complete surgical resection and contributes to therapeutic resistance. Tumor necrosis factor-like weak inducer of apoptosis (TWEAK), a member of the tumor necrosis factor (TNF) superfamily, can stimulate glioma cell invasion and survival via binding to fibroblast growth factor-inducible 14 (Fn14) and subsequent activation of the transcription factor NF-κB...

The use of recombinant adeno-associated viruses (rAAVs) ushered in a new millennium of gene transfer for therapeutic treatment of a number of conditions, including congenital blindness, hemophilia, and spinal muscular atrophy. rAAV vectors have remarkable staying power from a therapeutic standpoint, withstanding several ebbs and flows. As new technologies such as clustered regularly interspaced short palindromic repeat genome editing emerge, it is now the delivery tool-the AAV vector-that is the stalwart. The long-standing safety of this vector in a multitude of clinical settings makes rAAV a selling point in the advancement of approaches for gene replacement, gene knockdown, gene editing, and genome modification/engineering...

Preventing viral induced liver disease begins with an understanding of the host factors that define susceptibility to infection. Hepatitis C Virus (HCV) is a global health issue with an estimated 170 million infected individuals at risk of developing liver disease including fibrosis and hepatocellular carcinoma. The liver is the major reservoir supporting HCV replication and this hepatocellular tropism is defined by HCV engagement of cellular entry receptors. Hepatocytes are polarised in vivo and this barrier function limits HCV entry...

Rhabdomyosarcoma (RMS), a neoplasm characterized by undifferentiated myoblasts, is the most common soft tissue tumour in children. Therapeutic resistance is common in RMS and is often caused by acquired defects in the cellular apoptotic program. Smac mimetic compounds (SMCs) are a novel class of inhibitor of apoptosis (IAP) antagonists that are currently under clinical development as cancer therapeutics. We previously reported that cIAP1 is overexpressed in human primary RMS tumours and in patient-derived RMS cell lines where it drives resistance to apoptosis...

In the liver, the signal and function of tumor necrosis factor-like weak inducer of apoptosis (TWEAK) have mainly been assessed in association with liver regeneration. However, the effects of TWEAK on liver fibrosis have not been fully elucidated. To investigate the effects of TWEAK on human hepatic stellate cells (HSCs) and to explore the relevant potential mechanisms, human HSCs line-LX-2 were cultured with TWEAK. Cell migration was detected by transwell assay; cell viability was evaluated by Cell Counting Kit-8; the expression of MMP1, MMP2, MMP3, MMP7, MMP8, MMP9, MMP10, MMP11, MMP12, MMP13 gene was identified by quantitative real-time polymerase chain reaction and western blotting; the activity of matrix metalloproteinases (MMPs) was tested by enzyme-linked immuno sorbent assay; small interfering RNA transfection was applied for depletion of MMP9 and p65...

A synergy of a pre-accumulated genes with an autoimmunity advancing to slow abolition of pancreatic beta-cells causes insulin deficiency and results enrooting insulin dependent diabetes mellitus (IDDM). As per WHO data worldwide about 150 million people are diabetic and the number may rise to more than double by the year 2025. Any absolute cure for IDDM is not available yet, and one of the credible advent in the field include cell-based therapy. At this conjecture, mesenchymal stem cells (MSC) seems to have a specific and beneficial characteristics due to their in vivo as well as in vitro potential to mimic a pancreatic endocrine phenotype and immune-regulatory actions...
