Exposure to antioxidants and xenobiotics triggers the expression of a myriad of genes encoding antioxidant proteins, detoxifying enzymes, and xenobiotic transporters to offer protection against oxidative stress. This articulated universal mechanism is regulated through the cis-acting elements in an array of Nrf2 target genes called antioxidant response elements (AREs), which play a critical role in redox homeostasis. Though the Keap1/Nrf2/ARE system involves many players, AREs hold the key in transcriptional regulation of cytoprotective genes...

The imbalance of anti-inflammatory /pro- inflammatory cytokines plays an important role in the progression of atherosclerosis. Interleukin 35 (IL-35) is a novel member of the IL-12 family, consisting of an EBVinduced gene 3 (EBI3) subunit and a P35 subunit. IL-35 is an immunesuppressive cytokine mainly produced by regulatory T cells. Accumulating evidence suggests that IL-35 may represent a target for antiatherosclerotic therapy based on its several anti-inflammatory features. This review provide a brief overview of IL-35 biology and the role of IL-35 in the atherosclerosis, autoimmune disease and cancers...

The phase 3 PANORAMA-1 trial led to regulatory approvals of panobinostat (PAN) in combination with bortezomib (BTZ) and dexamethasone (DEX) for the treatment of multiple myeloma after ≥2 prior regimens, including BTZ and an immunomodulatory drug. Patient-reported outcomes (PROs) were assessed in PANORAMA-1, with data available for 73 patients in the PAN + BTZ + DEX arm and 74 patients in the placebo (PBO) + BTZ + DEX arm. Per the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), global health status/quality of life (QoL) scores initially declined with PAN + BTZ + DEX during the first 24 weeks before approaching baseline scores and remaining steady during the next 24 weeks, with no difference between arms at Week 48...

Neuroblastoma (NB), a developmental cancer, is often fatal, emphasizing the need to understand its pathogenesis and identify new therapeutic targets. The heterogeneous pathological and clinical phenotype of NB underscores the cryptic biological and genetic features of this tumor that result in outcomes ranging from rapid progression to spontaneous regression. Despite recent genome-wide mutation analyses, most primary NBs do not harbor driver mutations, implicating epigenetically-mediated gene regulatory mechanisms in the initiation and maintenance of NB...

The molecular processes and proteomic markers leading to tumor progression (TP) in cervical cancer (CC) are either unknown or only partially understood. TP affects metabolic and regulatory mechanisms that can be identified as proteomic changes. To identify which proteins are differentially expressed and to understand the mechanisms of cancer progression, we analyzed the dynamics of the tumor proteome in CC cell lines. This analysis revealed two proteins that are up-regulated during TP, GSTM3 and GSTP1. These proteins are involved in cell maintenance, cell survival and the cellular stress response via the NF-κB and MAP kinase pathways during TP...

Nuclear receptor NR1D2 is originally characterized as the repressor of genes involved in circadian rhythm. Recently, it is documented that NR1D2 is overexpressed in various cancers. However, the pathways and biological functions that NR1D2 involved in cancers remain poorly understood. Here, we reported that NR1D2 was abundant in human glioblastoma (GBM) tissue and cell lines but not primary human astrocytes. Silencing of NR1D2 changed the morphology of GBM cells, inhibited cell proliferation and motility, whereas had no effects on apoptosis...

Introduction : Asbestos has been used for thousands of years but only at a large industrial scale for about 100⁻150 years. The first identified disease was asbestosis, a type of incurable pneumoconiosis caused by asbestos dust and fibres. The latest estimate of global number of asbestosis deaths from the Global Burden of Disease estimate 2016 is 3495. Asbestos-caused cancer was identified in the late 1930's but despite today's overwhelming evidence of the strong carcinogenicity of all asbestos types, including chrysotile, it is still widely used globally...

Hypoxia-inducible factor-1α (HIF-1α) shifts the metabolism of glucose from highly efficient oxidative phosphorylation to less efficient glycolysis. Pyruvic acid thus accumulated is oxidized to lactic acid which is pumped out in the tumor microenvironment. Protons generated from the pentose phosphate pathway (PPP) and upon hydrolysis of ATP further enhance the acidity in the tumor microenvironment. The resultant pH in the tumor microenvironment activates an endoplasmic reticulum protein: sterol regulatory element binding protein-1c (SREBP-1c), which once activated enhances proliferation of the tumor cell...

Norcantharidin (NCTD) is a promising antitumor drug with low toxicity. It was reported to be able to regulate immunity, but the mechanism is not yet clear. Here we explored whether NCTD could enhance the antitumor immunity induced by prostate cancer cells vaccine. The results in vitro study showed that NCTD induced apoptosis and inhibited proliferation of Tregs. Mechanistic research showed that NCTD inhibited Akt activation and activated FOXO1 transcription, resulting in pro-apoptotic effect. The results in vivo study showed that more tumor-infiltrating Tregs existed within peripheral blood and tumor tissue after treating with the vaccine...

Noncanonical Wnt signaling functions independently of the β-catenin pathway to control diverse developmental processes, and dysfunction of the pathway contributes to a number of human pathological conditions, including birth defects and metastatic cancer. Progress in the field, however, has been hampered by the scarcity of functional assays for measuring noncanonical Wnt signaling activity. We recently described the Wnt5a-Ror-Kif26b (WRK) reporter assay, which directly monitors a post-transcriptional regulatory event in noncanonical Wnt signaling...

Interleukin-15 (IL-15) can promote both innate and adaptive immune reactions by stimulating CD8+ /CD4+ T cells and natural killer cells (NK) while showing no effect in activating T-regulatory (Treg) cells or inducing activation-associated death among effector T cells and NK cells. Thus, IL-15 is considered as one of the most promising molecules for antitumor immune therapy. To improve the drug-like properties of natural IL-15, we create an IL-15-based molecule, named P22339, with the following characteristics: 1) building a complex of IL-15 and the Sushi domain of IL-15 receptor α chain to enhance the agonist activity of IL-15 via transpresentation; 2) through a rational structure-based design, creating a disulfide bond linking the IL-15/Sushi domain complex with an IgG1 Fc to augment its half-life...

Globally, biosimilars are expected to have a key role in improving patient access to biological therapies and addressing concerns regarding the escalating cost of health care. Indeed, in Europe, increased use of biologics and reduced drug prices have been observed after the introduction of biosimilars. Recently, several monoclonal antibody biosimilars of anticancer therapies have been approved, and numerous others are in various stages of clinical development. Biosimilars are authorized via a regulatory pathway separate from that used for generic drugs; they are also regulated separately from novel biologics...

The consequences of apoptosis extend beyond mere death of the cell. We have shown that receptor-mediated recognition of apoptotic target cells by viable kidney proximal tubular epithelial cells (PTECs) inhibits PTEC proliferation, growth, and survival. Here we tested the hypothesis that continual exposure to apoptotic targets can induce a phenotypic change in responding PTECs, as in other instances of natural selection. In particular, we demonstrate that repeated exposure to apoptotic targets leads to emergence of a PTEC line (denoted BU...

Microbes are known to influence insect-plant interactions; however, it is unclear if host-plant diet influences the regulation of nutritional insect symbioses. The pea aphid, Acyrthosiphon pisum , requires its nutritional endosymbiont, Buchnera , for the production of essential amino acids. We hypothesize that key aphid genes that regulate the nutritional symbioses respond to host-plant diet when aphids feed on a specialized (alfalfa) compared to a universal host-plant diet (fava), which vary in amino acid profiles...
