Abstract
Artemisia argyi H. Lév. and Vaniot is a variety of Chinese mugwort widely cultured in central China. A. verlotorum Lamotte, another variety of Chinese mugwort, has been used in the southern region of China since ancient times. Despite their similar uses in traditional medicine, little is known about the differences in their active ingredients and potential benefits. Herein, the chemical compositions of the essential oils (EOs) from both varieties were analyzed using chromatography-mass spectrometry (GC-MS). A series of databases, such as the Traditional Chinese Medicine Systems Pharmacology database (TCMSP), SuperPred database and R tool, were applied to build a networking of the EOs. Our results revealed significant differences in the chemical compositions of the two Artemisia EOs. However, we found that they shared similar ingredient-target-pathway networking with diverse bioactivities, such as neuroprotective, anti-cancer and anti-inflammatory. Furthermore, our protein connection networking analysis showed that transcription factor p65 (RELA), phosphatidylinositol 3-kinase regulatory subunit alpha (PIK3R1) and mitogen-activated protein kinase 1 (MAPK1) are crucial for the biological activity of Artemisia EOs. Our findings provided evidence for the use of A. verlotorum as Chinese mugwort in southern China.

A novel pathway links oxidative stress to loss of insulin growth factor-2 (IGF2) imprinting through NF-κB activation. PLoS One 2014; 9:e88052.

Abstract
Genomic imprinting is the allele-specific expression of a gene based on parental origin. Loss of imprinting(LOI) of Insulin-like Growth Factor 2 (IGF2) during aging is important in tumorigenesis, yet the regulatory mechanisms driving this event are largely unknown. In this study oxidative stress, measured by increased NF-κB activity, induces LOI in both cancerous and noncancerous human prostate cells. Decreased expression of the enhancer-blocking element CCCTC-binding factor(CTCF) results in reduced binding of CTCF to the H19-ICR (imprint control region), a major factor in the allelic silencing of IGF2. This ICR then develops increased DNA methylation. Assays identify a recruitment of the canonical pathway proteins NF-κB p65 and p50 to the CTCF promoter associated with the co-repressor HDAC1 explaining gene repression. An IκBα super-repressor blocks oxidative stress-induced activation of NF-κB and IGF2 imprinting is maintained. In vivo experiments using IκBα mutant mice with continuous NF-κB activation demonstrate increased IGF2 LOI further confirming a central role for canonical NF-κB signaling. We conclude CTCF plays a central role in mediating the effects of NF-κB activation that result in altered imprinting both in vitro and in vivo. This novel finding connects inflammation found in aging prostate tissues with the altered epigenetic landscape.

Abstract
Intrinsic or acquired resistance to chemotherapeutic agents is a common phenomenon and a major challenge in the treatment of cancer patients. Chemoresistance is defined by a complex network of factors including multi-drug resistance proteins, reduced cellular uptake of the drug, enhanced DNA repair, intracellular drug inactivation, and evasion of apoptosis. Pre-clinical models have demonstrated that many chemotherapy drugs, such as platinum-based agents, antracyclines, and taxanes, promote the activation of the NF-κB pathway. NF-κB is a key transcription factor, playing a role in the development and progression of cancer and chemoresistance through the activation of a multitude of mediators including anti-apoptotic genes. Consequently, NF-κB has emerged as a promising anti-cancer target. Here, we describe the role of NF-κB in cancer and in the development of resistance, particularly cisplatin. Additionally, the potential benefits and disadvantages of targeting NF-κB signaling by pharmacological intervention will be addressed.

Abstract
AIM To characterize the activation of the nuclear factor (NF)-kappaB pathway in diffuse large B-cell lymphoma (DLBCL) by immunohistochemistry. METHODS AND RESULTS Sixty-six DLBCLs treated with anthracycline-containing chemotherapy were evaluated with antibodies against phosphorylated p65 (P-p65), p65, p50, p52, IKK alpha, and phosphorylated I kappaB (P-I kappaB). NF-kappaB activation was based on the expression of P-p65, P-I kappaB, and nuclear expression of p65 or p52 in the tumour cells. P-p65 and P-I kappaB were expressed in 13 (20%) and 17 cases (26%), respectively. p65, p52 and IKK alpha were found in the cytoplasm. A correlation was found between expression of P-p65 and P-I kappaB (P < 0.0001), but not between the two subtypes of DLBCL [germinal centre B cell and non-germinal centre (GC)]. P-p65+ tumours showed a better response to chemotherapy (P = 0.025) and a trend to increased event-free survival (P = 0.08). However, P-I kappaB expression was not associated with either clinical response or survival. Bcl-2 was not preferentially expressed on DLBCL tumours with NF-kappaB activation, as determined by expression of P-p65 and P-I kappaB proteins. CONCLUSIONS NF-kappaB activation in DLBCL is preferentially mediated through the classical pathway and a novel mechanism involving phosphorylation of p65. Activation of NF-kappaB by P-p65 is associated with good prognosis. NF-kappaB activation is not confined to non-GC DLBCL exclusively.

Abstract
CTCF, a nuclear transcriptional factor, is a multifunctional protein and involves regulation of growth factor- and cytokine-induced cell proliferation/differentiation. In the present study, we investigated the role of CTCF in protecting stress-induced apoptosis in various human cell types. We found that UV irradiation and hyper-osmotic stress induced human corneal epithelial (HCE) and hematopoietic myeloid cell apoptosis detected by significantly increased caspase 3 activity and decreased cell viability. The stress-induced apoptotic response in these cells requires down-regulation of CTCF at both mRNA and protein levels, suggesting that CTCF may play an important role in downstream events of stress-induced signaling pathways. Inhibition of NFkappaB activity prevented stress-induced down-regulation of CTCF and increased cell viability against stress-induced apoptosis. The anti-apoptotic effect of CTCF was further studied by manipulating CTCF activities in HCE and hematopoietic cells. Transient transfection of cDNAs encoding full-length human CTCF markedly suppressed stress-induced apoptosis in these cells. In contrast, knocking down of CTCF mRNA using siRNA specific to CTCF significantly promoted stress-induced apoptosis. Thus, our results reveal that CTCF is a down stream target of stress-induced signaling cascades and it plays a significant anti-apoptotic role in regulation of stress-induced cellular responses in HCE and hematopoietic myeloid cells.

Abstract
NF-kappaB is an inducible transcription factor that plays a role in the expression of over one hundred genes involved in immunity, inflammation, proliferation, and in defense against apoptosis. NF-kappaB has been known to be redox regulated for some time and is a direct target for oxidation that can affect its ability to bind to DNA. Reactive oxygen species (ROS) have been identified as second messengers in cells, and play a role in receptor signaling and posttranslation modification of signaling molecules. These posttranslation modifications include oxidations of critical cysteines to sulfenic acids or mixed disulfides, which can affect the activity of proteins. Many kinases involved in direct or indirect activation of NF-kappaB are affected by oxidants and therefore, have the potential to alter NF-kappaB activity. This review will provide a summary of the NF-kappaB family, their activation and regulation, followed by a summary of cytoplasmic and nuclear kinases in this pathway whose activity is affected by oxidants. Additionally, recent investigations have revealed that the JNK signaling pathway, which is known to be redox regulated, and pro-apoptotic, is inhibited by NF-kappaB signaling. The crosstalk of NF-kappaB with other signaling pathways is therefore critical for cellular fate, notably survival or cell death under oxidative conditions, and will also be reviewed.

Abstract
A defect in apoptosis is almost always linked to many pathologies, including cancer. Carcinogenesis has been linked to abnormalities in the apoptotic pathway, and many drugs that are targeted at different parts of this pathway are being developed. There have been many promising drugs that target the extrinsic death receptor pathway as well as the intrinsic mitochondrial apoptotic pathway. There have also been developments in targeting initiator and effector caspases, as well as the death domains that are involved in transducing the apoptotic signals. In this review, the authors will briefly explain how apoptosis deregulation can lead to cancer and discuss drugs that promise success in targeting this anomaly. This article shall also explain how co-treatments with chemotherapy can increase survival of cancer patients. There is a problem of acquired resistance in some of these therapies but there may be ways to overcome this.

Abstract
Highly inducible heme oxygenase (HO)-1 is protective against acute and chronic inflammation. HO-1 generates carbon monoxide (CO), ferrous iron, and biliverdin. The aim of this study was to investigate the protective effects of biliverdin against sepsis-induced inflammation and intestinal dysmotility. Cecal ligation and puncture (CLP) was performed on Sprague-Dawley rats under isoflurane anesthesia with and without intraperitoneal biliverdin injections, which were done before, at the time of CLP, and after CLP. In vivo gastrointestinal transit was carried out with fluorescein-labeled dextran. Jejunal circular muscle contractility was quantified in vitro using organ bath-generated bethanechol dose-response curves. Neutrophilic infiltration into the muscularis externa was quantified. The jejunal muscularis was studied for cytokine mRNA expressions [interleukin (IL)-6, monocyte chemoattractant protein (MCP)-1, inducible nitric oxide synthase, cyclooxygenase-2, biliverdin, IL-10, and HO-1] using real-time RT-PCR. Biliverdin treatment prevented the sepsis-induced suppression of gastrointestinal muscle contractility in vivo and in vitro and significantly decreased neutrophilic infiltration into the jejunal muscularis. Inflammatory mRNA expressions for small bowel IL-6 and MCP-1 were significantly reduced after biliverdin treatment in CLP-induced septic animals compared with untreated septic animals. The anti-inflammatory mediator expression of small bowel IL-10 was significantly augmented after CLP at 3 h compared with untreated septic animals. These findings demonstrate that biliverdin attenuates sepsis-induced morbidity to the intestine by selectively modulating the inflammatory cascade and its subsequent sequelae on intestinal muscularis function.

Abstract
Nuclear factor-kappaB (NF-kappaB) is generally viewed as anti-apoptotic and oncogenic, leading to a quest for its inhibitors. However, recent evidence suggests that in some situations NF-kappaB may promote apoptosis. Depending on the specific cell type and the stimulus involved, NF-kappaB activation may lead to either anti- or pro-apoptotic response. Both these effects can be mediated by NF-kappaB in a context-dependent manner by selectively regulating its target genes. In this review, we discuss the evidence for NF-kappaB's pro-apoptotic role and explore the possible mechanisms behind it. We emphasize that rather than trying to inhibit NF-kappaB in cancer therapy, agents should be developed to unleash its pro-apoptotic ability.

Abstract
NF-kappaB-inducing kinase (NIK) has been implicated as an essential component of NF-kappaB activation. However, the regulatory mechanism of NIK signaling remains elusive. We have identified a novel NIK interacting protein, TNAP (for TRAFs and NIK-associated protein). In mammalian cells, TNAP physically interacts with NIK, TRAF2, and TRAF3 but not IKK1 or IKK2. TNAP specifically inhibits NF-kappaB activation induced by tumor necrosis factor (TNF)-alpha, TNF receptor 1, TRADD, RIP, TRAF2, and NIK but does not affect IKK1- and IKK2-mediated NF-kappaB activation. Knockdown of TNAP by lentiviral-mediated small interference RNA potentiates TNF-alpha-induced NF-kappaB activation. TNAP suppresses NIK kinase activity and subsequently reduces p100 processing, p65 phosphorylation, and IkappaBalpha degradation. These data suggest that TNAP is a repressor of NIK activity and regulates both the classical and alternative NF-kappaB signaling pathways.
