Systems Biology Approaches and Precision Oral Health: A Circadian Clock Perspective
Conclusion Most head and neck pathologies show a broad cellular heterogeneity making it difficult to achieve an accurate diagnosis and efficient treatment (Graf and Zavodszky, 2017; Lo Nigro et al., 2017). Single cell analysis of circadian omics (Lande-Diner et al., 2015; Abraham et al., 2018), may be a crucial tool needed in the future to fully understand the circadian control of head and neck diseases. It becomes more obvious that there is only a small genetic component but a largely unknown epigenetics and/or environmental component for most of the head and neck pathologies (Moosavi and Motevalizadeh Ardekani, 2016; He...

Plant-Derived Alkaloids: The Promising Disease-Modifying Agents for Inflammatory Bowel Disease
Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

Hepatoma-Derived Growth Factor and DDX5 Promote Carcinogenesis and Progression of Endometrial Cancer by Activating β-Catenin
Conclusion: Our results provide novel evidence that HDGF interacts with DDX5 and promotes the progression of EC through the induction of β-catenin. Introduction Endometrial cancer (EC) comprises the most common malignancy involving the female genital tract and the fourth most common malignancy in women after breast, lung, and colorectal cancers (1). In 2012, approximately 320,000 new cases of EC were diagnosed worldwide and the incidence is increasing (2). Currently, endometrial carcinogenesis is thought to be a multi-step process involving the coordinated interaction of hormonal regulation, gene mutation, ad...

Complement C5b-9 and Cancer: Mechanisms of Cell Damage, Cancer Counteractions, and Approaches for Intervention
In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

ROS Modifiers and NOX4 Affect the Expression of the Survivin-Associated Radio-Adaptive Response.
Abstract The survivin-associated radio-adaptive response can be induced following exposure to ionizing radiation in the dose range from 5 to 100 mGy, and its magnitude of expression is dependent upon the TP53 mutational status of cells and ROS signaling. The purpose of the study was to investigate the potential role of ROS in the development of the survivin-associated adaptive response. Utilizing human colon carcinoma HCT116 TP53 wild type (WT) and HCT116 isogenic TP53 null mutant (Mut) cell cultures, the roles of inter- and intracellular ROS signaling on expression of the adaptive response as evidenced by changes...

Upregulated plasmacytoma variant translocation 1 promotes cell proliferation, invasion and metastasis in colorectal cancer.
Authors: Wang C, Zhu X, Pu C, Song X Abstract Emerging evidence indicates that the long non-coding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) is associated with tumourigenesis in various types of cancer. However, its specific effects on the proliferation, invasion and metastasis of colorectal cancer (CRC) are still poorly understood. The present study aimed to investigate PVT1 expression in CRC and explore its role in CRC pathogenesis. The reverse transcriptase‑quantitative polymerase chain reaction (RT‑qPCR) technique was used to assess PVT1 expression in CRC cell lines. Gene Expression Omnibus ...

Dimethyl Fumarate Controls the NRF2/DJ-1 Axis in Cancer Cells: Therapeutic Applications
The transcription factor NRF2 (NFE2L2), regulates important antioxidant and cytoprotective genes. It enhances cancer cell proliferation and promotes chemoresistance in several cancers. Dimethyl fumarate (DMF) is known to promote NRF2 activity in noncancer models. We combined in vitro and in vivo methods to examine the effect of DMF on cancer cell death and the activation of the NRF2 antioxidant pathway. We demonstrated that at lower concentrations (<25 μmol/L), DMF has a cytoprotective role through activation of the NRF2 antioxidant pathway. At higher concentrations, however (>25 μmol/L), DMF caused oxidative s...

Perturbation of the Warburg effect increases the sensitivity of cancer cells to TRAIL-induced cell death.
Abstract Tumor necrosis-factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF-superfamily that selectively induces apoptosis through death receptors (DRs) 4 and/ or DR5 in cancer cells, without affecting normal cells. Unfortunately, many clinical studies have shown that cancer cells acquire TRAIL-resistance and thus avoid TRAIL-induced apoptosis. In the current study, we newly found that PTBP1, a splicer protein that plays an important role in energy metabolism is highly expressed in TRAIL-resistant human colon cancer DLD-1. Interestingly, silencing PTBP1 by using siRNA for PTBP1 (siR-PTBP1...

Interaction of DNA demethylase and histone methyltransferase upregulates Nrf2 in 5-fluorouracil-resistant colon cancer cells.
Authors: Kang KA, Piao MJ, Ryu YS, Kang HK, Chang WY, Keum YS, Hyun JW Abstract We recently reported that DNA demethylase ten-eleven translocation 1 (TET1) upregulates nuclear factor erythroid 2-related factor 2 (Nrf2) in 5-fluorouracil-resistant colon cancer cells (SNUC5/5-FUR). In the present study, we examined the effect of histone modifications on Nrf2 transcriptional activation. Histone deacetylase (HDAC) and histone acetyltransferase (HAT) were respectively decreased and increased in SNUC5/5-FUR cells as compared to non-resistant parent cells. Mixed-lineage leukemia (MLL), a histone methyltransferase, was upr...

DHA-induced stress response in human colon cancer cells-focus on oxidative stress and autophagy.
Abstract Polyunsaturated fatty acids (PUFAs) are important constituents of the diet and health benefits of omega-3/n-3 PUFAs, especially eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) have been well documented in relation to several diseases. Increasing evidence suggests that n-3 PUFAs may have anticancer activity and improve the effect of conventional cancer therapy. The mechanisms behind these effects are still unclear and need to be elucidated. We have examined the DHA-induced stress response in two human colon cancer cell lines, SW620 and Caco-2. SW620 cells are growth-inhibited a...

Epithelial-specific ETS-1 (ESE1/ELF3) regulates apoptosis of intestinal epithelial cells in ulcerative colitis via accelerating NF-κB activation
In this study, we reported for the first time that ESE1/ELF3 was over-expressed in intestinal epithelial cells (IECs) of patients with UC. In DSS-induced colitis mouse models, we observed the up-regulation of ESE1/ELF3 accompanied with the elevated levels of IEC apoptotic markers (active caspase-3 and cleaved PARP) and NF-κB activation indicators [phosphorylated NF-κB p65 subunit (p-p65) and p-IκB] in colitis IECs. Increased co-localization of ESE1/ELF3 with active caspase-3 (and p-p65) in IECs of the DSS-induced colitis group further indicated the possible involvement of ESE1/ELF3 in NF-κB-mediated IEC apoptosis in UC...

Abstract 1393: Correlating the expression of protein kinase C isozymes with the transformed phenotype in colorectal cancer
Protein Kinase C (PKC) is a family of serine/threonine kinases that are involved in almost every signal transduction pathway. Their regulation is mediated by several factors and by binding to a group of scaffolding proteins called RACKs (Adams et al. 2011). The development of PKC modulators with anti-cancer therapeutic value is a major target in cancer. However, this task is made difficult because PKC has an important role to play in normal processes and the PKC family consists of at least 12 different isozymes. In colon cancer, there is differential expression of the PKC isozymes, giving the cancer cells a migratory advan...
