    Abstract High mortality rates in ovarian cancer have been linked to recurrence, metastasis, and chemoresistant disease, which are known to involve not only genetic changes but also epigenetic aberrations. In ovarian cancer, adipose-derived stem cells from the omentum (O-ASCs) play a crucial role in supporting the tumor and its tumorigenic microenvironment, further propagating epigenetic abnormalities and dissemination of the disease. Epigallocatechin gallate (EGCG), a DNA methyltransferase inhibitor derived from green tea, and Indole-3-carbinol (I3C), a histone deacetylase inhibitor from cruciferous vegetables, carry promising effects in reprograming aberrant epigenetic modifications in cancer. Therefore, we demonstrate the action of these diet-derived compounds in suppressing the growth of 3D ovarian cancer spheroids or organoids as well as post-treatment cancer recovery through proliferation, migration, invasion, and colony formation assays when compared to the synthetic epigenetic compound Panobinostat with or without standard chemotherapy. Finally, given the regulatory role of the secretome in growth, metastasis, chemoresistance, and relapse of disease, we demonstrate that natural epigenetic compounds can regulate the secretion of protumorigenic growth factors, cytokines, extracellular matrix components, and immunoregulatory markers in human ovarian cancer specimens. While further studies are needed, our results suggest that these treatments could be considered in the future as adjuncts to standard chemotherapy, improving efficiency and patient outcomes.

    Abstract TWEAK (tumor necrosis factor-like weak inducer of apoptosis) is a member of the TNF superfamily that controls a multitude of cellular events including proliferation, migration, differentiation, apoptosis, angiogenesis, and inflammation. TWEAK control of these events is via an expanding list of intracellular signalling pathways which include NF-κB, ERK/MAPK, Notch, EGFR and AP-1. Two receptors have been identified for TWEAK - Fn14, which targets the membrane bound form of TWEAK, and CD163, which scavenges the soluble form of TWEAK. TWEAK appears to elicit specific events based on the receptor to which it binds, tissue type in which it is expressed, specific extrinsic conditions, and the presence of other cytokines. TWEAK signalling is protective in healthy tissues, but in chronic inflammatory states become detrimental to the tissue. Consistent data show a role for the TWEAK/FN14/CD163 axis in metabolic disease, chronic autoimmune diseases, and acute ischaemic stroke. Low circulating concentrations of soluble TWEAK are predictive of poor cardiovascular outcomes in those with and without diabetes. This review details the current understanding of the TWEAK/Fn14/CD163 axis as one of the chief regulators of immune signalling and its cell-specific role in metabolic disease development and progression.

    Abstract TNFAIP3 encodes a zinc finger protein called A20, which has potent anti-inflammatory and anti-apoptotic properties. A20 promotes beta-cell survival and protects against islet graft rejection in experimental models. The current study sought to investigate the mechanisms underlying the protective role of A20 in the pancreatic beta-cell. Two islet cell types were used for experiments: the insulin-secreting BRIN-BD11 cell line and human islet cells. A20 was silenced using siRNA against TNFAIP3, and knockdown was confirmed by qPCR and immunostaining of cells. Cell viability, cytotoxicity and apoptosis were assessed using the ApotoxGlo assay. Glucose-stimulated insulin secretion and production of inflammatory cytokines (TNFa, IL1b and IFNg) were measured by ELISA. Expression of beta-cell regulatory genes (Abcc8, Kcnj11, Kcnq1, Gck, Scl2a2) and transcription factors (Hnf1a, Pdx1, Nkx6.1, Ngn3) was determined by qPCR. A20 deficiency increased apoptosis, impaired glucose-induced insulin secretion, and reduced expression of beta-cell regulatory genes and transcription factors. Addition of recombinant A20 normalized gene expression profiles. TNFa, IL1b and IFNg were elevated in A20 deficient cells and found to independently elicit changes in gene expression. Analysis of PCR array data suggests that A20 action in the beta cell is largely, although not exclusively, driven by the P65 subunit of NF-kB. The current report demonstrates a role for A20 in controlling beta-cell integrity and survival, which likely results from the regulation of inflammatory signalling. Of particular note is the impact that A20 deficiency has on the expression of transcription factors regulating the maturation and normal function of beta cells.

    Abstract Background: Acute pancreatitis (AP) is a frequent cause of hospitalization with long-term health consequences, including type 3c diabetes mellitus (DM). The incidence and risk factors for new-onset morbidities after AP need to be clarified to inform a personalized medicine approach.
    Methods: Using a longitudinal electronic healthcare record-linkage analysis, all patients admitted to hospital in Scotland with a first episode of AP between 1 April 2009 and 31 March 2012 and followed for a minimum of 5 years after their index AP admission were identified. All new-onset morbidity with specific focus on type 3c DM were analysed and, using time-split multiple regression.
    Results: A total of 2047 patients were included. AP requiring critical care was followed by 2 years of heightened risk (HR 5.24) of developing type 3c DM, increased risk of new-onset cardiac disease (HR 1.61), and renal disease (HR 2.96). The additional risk conferred by critical care AP had a negative interaction with time, whereas additional risk associated with male sex and a non-gallstone aetiology was long lasting.
    Conclusion: Based on these findings, a personalized approach to include type 3c DM screening for a minimum of 2 years for individuals who required critical care when hospitalized with AP is recommended.

    Abstract Abstract Background With the introduction of oncogenic Human Papillomavirus (HPV) testing into cervical screening there is a renewed focus on primary prevention among high-risk groups. To date, little is known about the effectiveness of this program, and the extent to which individual-level factors, such as psychosocial health and agency, may play a role. In particular, it is unclear if knowledge of one’s oncogenic HPV status impacts on adherence behaviors amongst women with screening abnormalities. The purpose of this study was to identify if clinical, demographic or psychosocial factors predict non-adherence with recommended colposcopy follow-up. Methods This prospective pilot study included 145 women referred to a large Toronto colposcopy clinic between December, 2013 and September, 2014. Demographic, clinical and psychosocial characteristics were collected at three points in time: (1) at initial colposcopy consultation; (2) 4–6 weeks following initial consultation, and; (3) at time of follow-up appointment (within 12 months of initial consultation). Results Overall, 13% (n = 145) of the women were classified as non-adherent. Older women (OR = 0.73, p < 0.01) and those with higher-grade lesions (OR = 0.10, p < 0.01) were less likely to be non-adherent, whereas current smokers (OR = 22.46, p < 0.01) were more likely to be non-adherent. While not statistically significant, variation in rates of non-adherence amongst the various HPV status groups (untested; 15.3%, HPV positive; 5.3%, HPV negative; 6.7%) warrants further study. Conclusion Findings of this study indicate that younger women, those with higher-grade lesions and current smokers were more likely to be non-adherent to recommended colposcopy follow-up. While HPV status did not reach statistical significance, the direction of this finding suggests that testing for HPV may have a positive reinforcing role on adherence to follow-up. The direction of this finding warrants further study, and potentially a practical clinical goal as HPV testing for ...

Here, we utilise focused ion beam – scanning electron microscopy nanotomography (FIB-SEM-NT) to quantitatively characterise the morphology of printed nanostructured networks and their devices using nanometre-resolution 3D images. The influence of nanosheet/nanowire size on network structure in printed films of graphene, WS2 and silver nanosheets (AgNSs), as well as networks of silver nanowires (AgNWs), is investigated. We present a comprehensive toolkit to extract morphological characteristics including network porosity, tortuosity, specific surface area, pore dimensions and nanosheet orientation, which we link to network resistivity. By extending this technique to interrogate the structure and interfaces within printed vertical heterostacks, we demonstrate the potential of this technique for device characterisation and optimisation.
