Breast cancer is the most important cause of death in women globally. Though, improved survival is due to the developments in the screening techniques, initial diagnosis, and advances in treatments. Numerous factors contributed in the progression of breast cancer, such as inflammation. The most significant factor involved in the inflammatory process, is T helper 17 (Th17) cells. Th17 cells have an exceptional role in many of inflammatory diseases like psoriasis, rheumatoid arthritis, and breast cancer through production of proinflammatory cytokine (IL17)...

Small hepatocyte-like progenitor cells (SHPCs) transiently form clusters in rat livers treated with retrorsine (Ret)/70% partial hepatectomy (PH). When Thy1+ cells isolated from d-galactosamine-treated rat livers were transplanted into the livers of Ret/PH-treated rats, the mass of the recipient liver transiently increased during the first 30 days after transplantation, suggesting that liver regeneration was enhanced. Here we addressed how Thy1+ cell transplantation stimulates liver regeneration. We found that the number and size of SHPC clusters increased in the liver at 14 days after transplantation...

Keratoconus (KTCN) is a protrusion and thinning of the cornea, resulting in impairment of visual function. The extreme genetic heterogeneity makes it difficult to discover factors unambiguously influencing the KTCN phenotype. In this study, we used whole-exome sequencing (WES) and Sanger sequencing to reduce the number of candidate genes at the 5q31.1-q35.3 locus and to prioritize other potentially relevant variants in an Ecuadorian family with KTCN. We applied WES in two affected KTCN individuals from the Ecuadorian family that showed a suggestive linkage between the KTCN phenotype and the 5q31...

Overexpression of IL17RB is associated with poor prognosis and short survival of the breast cancer patients.IL17RB/IL17B signaling triggers a substantial increase in the cell growth, proliferation and migration through the activation of NF-κB as well as the up-regulation of the Bcl-2. In this study we designed carboxymethyl dextran (CMD) Chitosan nanoparticles (ChNPs) to encapsulated IL17RB siRNA and doxorubicin (DOX) as an anticancer drug. Then we investigated the efficiency of the simultaneous delivery of drug/siRNA on viability and gene expression of MDA-MB361 cell lines...

Previous microarray analyses of RNAs from 8-cell (8C) human embryos revealed a lack of cell cycle checkpoints and overexpression of core circadian oscillators and cell cycle drivers relative to pluripotent human stem cells [human embryonic stem cells/induced pluripotent stem (hES/iPS)] and fibroblasts, suggesting growth factor independence during early cleavage stages. To explore this possibility, we queried our combined microarray database for expression of 487 growth factors and receptors. Fifty-one gene elements were overdetected on the 8C arrays relative to hES/iPS cells, including 14 detected at least 80-fold higher, which annotated to multiple pathways: six cytokine family (CSF1R, IL2RG, IL3RA, IL4, IL17B, IL23R), four transforming growth factor beta (TGFB) family (BMP6, BMP15, GDF9, ENG), one fibroblast growth factor (FGF) family [FGF14(FH4)], one epidermal growth factor member (GAB1), plus CD36, and CLEC10A...

BACKGROUND: Glioblastomas (GBM) are comprised of a heterogeneous population of tumor cells, immune cells, and extracellular matrix. Interactions among these different cell types and pro-/anti-inflammatory cytokines may promote tumor development and progression. AIMS: The objective of this study was to develop a cytokine-related gene signature to improve outcome prediction for patients with primary GBM. METHODS: Here, we used Cox regression and risk-score analysis to develop a cytokine-related gene signature in primary GBMs from the whole transcriptome sequencing profile of the Chinese Glioma Genome Atlas (CGGA) database (n=105)...

Intracortical electrodes record neural signals directly from local populations of neurons in the brain, and conduct them to external electronics that control prosthetics. However, the relationship between electrode design, defined by shape, size and tethering; and long-term (chronic) stability of the neuron-electrode interface is poorly understood. Here, we studied the effects of various commercially available intracortical electrode designs that vary in shape (cylindrical, planar), size (15 μm, 50 μm and 75 μm), and tethering [electrode connections to connector with (tethered) and without tethering cable (untethered)] using histological, transcriptomic, and electrophysiological analyses over acute (3 day) and chronic (12 week) timepoints...

Kindlin-2 is a novel focal adhesion gene mediating the cell-extracellular matrix (ECM) adhesion. Tumor-associated macrophages (TAMs) play an important role in linking chronic inflammation to cancer progression. Both kindlin-2 and TAMs have been found to promote the invasion of gastric cancer cells in our previous studies. However, the correlation between kindlin-2 and TAMs remains unclear. Real-time RT-PCR was used to investigate kindlin-2 expression in the AGS, NCI and Hs-746T gastric cancer cell lines co-cultured with TAMs under normal or hypoxic conditions...

Few studies have investigated the changes of Th1- and Th2-type cytokines in pulmonary embolism (PE) patients. In this study, the gene expression of interleukins and the balance of Th1- and Th2-type cytokines in the peripheral blood mononuclear cells (PBMCs) of PE patients and controls were investigated. A total of 20 PE patients and 20 gender- and age-matched controls were included in the study. Human cDNA microarray analysis was used to detect the differences in cytokine gene expression between the two groups and a random variance model corrected t-test was used to analyze the statistical data...

A new family of cytokines, the interleukin (IL)-17 family, has recently been defined, which reveals unique functions and distinct ligand-receptor signaling systems. This family contains six members, IL-17 (also called IL-17A), IL17B, IL-17C, IL-17D, IL-17E (IL-25) and IL-17F. The IL-17F gene was discovered in 2001, and is located on chromosome 6p12. Notably, among this family, IL-17F has been well characterized both in vitro and in vivo, and has been shown to have a pro-inflammatory role in asthma. IL-17F is clearly expressed in the airway of asthmatics and its expression level is correlated with disease severity...

Drug resistance is the major setback of acute myeloid leukemia (AML) therapy. Notch proteins have demonstrated functional regulation in cell proliferation, differentiation, and apoptosis and thus may affect drug resistance. Our study aimed to identify the Notch-related gene profile in drug-resistant AML cells and provide potential strategies for resistant AML therapy. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was conducted to detect the cytotoxicity of adriamycin toward K562 and drug-resistant K562/A02...

BACKGROUND AND OBJECTIVE: A role for cytokines and growth factors in mediating the cellular and molecular events involved in orthodontic tooth movement is well established. The focus to date, however, has been largely on individual mediators, rather than to study cytokines in terms of complex interacting networks. Our objective was to expand our knowledge of the cytokines and growth factors expressed by human periodontal ligament (PDL) cells and to identify new genes that are responsive to mechanical deformation...

INTRODUCTION: The growth plate response following radiotherapy is poorly understood. In particular, little is known about the changes in growth plate growth factors and cytokines following irradiation. The hypothesis was that a limited number of growth factors and cytokines play a role in growth plate proliferative and hypertrophic chondrocyte radio-recovery. METHODS: The right limbs of 6 rats were irradiated (17.5 Gy), leaving the left limbs as controls. Limbs were harvested 1 (n = 3) and 2 (n = 3) weeks later...

Genetic predisposition to coeliac disease (CD) is determined primarily by alleles at the HLA-DQB locus, and evidence exists implicating other major histocompatibility complex-linked genes (6p21) and the CTLA4 locus on chromosome 2q33. In addition, extensive family studies have provided strong, reproducible evidence for a susceptibility locus on chromosome 5q (CELIAC2). However, the gene responsible has not been identified. We have assayed genetic variation at the IL4, IL5, IL9, IL13, IL17B and NR3C1 (GR) loci, all of which are present on chromosome 5q and have potential or demonstrated involvement in autoimmune and/or inflammatory disease, in a sample of 409 CD cases and 355 controls...

BACKGROUND: Articular cartilage homoeostasis is critical for joint function. The steady state homoeostasis of articular cartilage is a balance between anabolic morphogens such as cartilage derived morphogenetic proteins (CDMPs) and bone morphogenetic proteins (BMPs) of the BMP family and catabolic cytokines such as interleukin (IL)1, IL17, and tumour necrosis factor alpha. Although bone and articular cartilage are adjacent tissues, there is a profound difference in their regeneration potential...
