    How does the Regulation of Ubiquitin/ubiquitin-like Pathways Determine Cellular Responses to Reactive Oxygen Species?
    Reference Code: CB108

    Details:
    Name of the supervisors
    Professor B Morgan, Institute for Cell and Molecular Biosciences (ICAMB)
    Dr J Quinn, Institute for Cell and Molecular Biosciences (ICAMB)

    Sponsor
    This studentship is sponsored by the Biotechnology and Biological Sciences Research Council (BBSRC) as part of the Doctoral Training Partnership (DTP).

    Duration of the award
    Four years (MRes Biosciences followed by a three-year PhD).

    Project description
    Oxidative stress-induced cell damage caused by reactive oxygen species (ROS) is associated with cancer, diabetes, cardiovascular disease, certain neurodegenerative diseases and shortened lifespan. However, ROS are also used by the immune system to defend against disease-causing organisms and play important roles as signalling molecules. Thus, to understand how cells function in ageing and disease it is important to explore the mechanisms by which cells sense and respond to ROS. Recently we and others, using yeast as a model, discovered that conserved antioxidants, previously thought to mainly act in restoring redox homeostasis, play key roles in sensing and signalling the presence of ROS [1,2]. Furthermore, ubiquitin (Ub)/ubiquitin-like (Ubl) modifications of proteins regulate many fundamental biological processes and, excitingly, we recently demonstrated that the specific sensitivity of a conserved ubiquitin pathway enzyme, Cdc34, to oxidation coordinates cell cycle delay to prevent oxidative stress-induced damage [3].

    Thus, the project aim is to build on these exciting data, using yeast as a model eukaryote, to determine the regulation and roles of conserved Ub/Ubl protein modifications in responses to ROS. Broadly applicable experience will be obtained of genetics, biochemical, cell biology, microscopy, molecular biology techniques, and also techniques to investigate protein modification.

    Traditional medicine of Chinese hold a big share of Pharmaceutical market in the entire China. It is said that annually $ 41 billion are earned from this business by the pharmaceutical companies. Recently, Chinese and US based scientists have revealed that the material used in these medicines does have scientific importance and considered to be untapped source for all kinds of ailments. Chinese deputy health minister quoted as saying that $ 1 billion had been used last year for investigating the drugs with the help of biotechnology.

    It is the reason that scientists from China and US have collaboratively agreed to improve the quality of the drugs with the use of modern technology. Hong Kong based biotech technologists hold the opinion that researches are under way and if the products are improved , the sale of Chinese traditional medicines would be boombing in the market. On the other hand, Yung H Wong the famous director of life sciences division at the Biotechnology Research Institute in Hong Kong, categorically says that biotechnology is the only science that has capacity to unravel this perplexity.

    The US based researchers have also said that the traditional medicine from China are treasures for us. Besides, all the biotech research institutes have launched the research initiative for developing herbal medicines of China as per international standards.

    The Hong Kong Institute of Biotechnology was one of those first institutions which took the initiative. Presently, most of the herbal medicines of China are not allowed to be sold in Europe as European Union has embarked sanctions over the local pharmaceutical companies of China. EU holds the view that the products of China does not meet with international medicine standards and can not be accepted.

    It was the reason that Hong Kong government owned another science park with approximate area of 10000 square meters for new biotechnological labs.

    Scientists in the University of Washington have used nanoparticle technology to immunise mice with what they term ‘just-in-time’ vaccines in a process that could revolutionise distribution and accessibility of vaccines if successfully extended to humans in the future. Current technologies rely on making batches of vaccines centrally and then distributing them to centres where they need to be used, with refrigeration required at all steps. The University of Washington researchers used rudimentary equipment and a single-pot process to produce their vaccine. If this could be extended to humans, it raises the possibility of making vaccines at the site at which they are needed. This would be especially advantageous in the developing world, allowing doctors and scientists locally to act to produce the necessary vaccines cheaply and easily at the first signs of an epidemic.

    The University of Washington study, published this week in the journal Nanomedicine: Nanotechnology, Biology and Medicine, used a fusion protein created between ovalbumin, which is often used as a model antigen in animal studies, and a calcium phosphate binding domain. This effectively created a mineralised biocompatible adjuvant in a single step. When administered to mice, this nanoparticle induced the production of an ovalbumin-specific antibody response and class-switch recombination. Importantly, when the mice were subsequently challenged with an influenza virus containing an ovalbumin-derived peptide, the mice produced substantially higher levels of ovalbumin-specific CD8 T cells- protective killer cells of the immune system- and a cytokine called interferon-gamma (IFN-gamma) which is toxic to invading pathogens, compared to mice which received the protein in the absence of the nanoparticle. A robust immune response was observed 8 months after vaccination. The mechanism of action of the nanoparticle appears to reside in its ability to ferry antigen to the secondary lymph nodes, where immune reactions can be mounted. There they are detected by specialised immune cells called dendritic cells, which in turn can then present antigen to the immune killer cells such as CD8 T cells.

    The strength of this technology lies in its simplicity, with production possible using rudimentary equipment, and lack of reliance on transport and refrigeration of vaccines. Production costs would be much lower and production could be tailored to match the vaccines to the relevant specific infectious agents at local level. Additionally, there is the possibility of administering vaccine via alternative methods to injection, such as a disposable patch. There is a long road ahead for this technology in terms of human testing but one day it may have a positive impact on vaccination programmes worldwide.

    The findings of a new study from the University of Eastern Finland may suggest that including sources of vitamin E in the diet, such as vegetable oils including palm oil, sunflower, corn, soybean and olive oil or using vitamin E supplements, could confer an advantage in avoiding memory disorders in later life. The study, published in Experimental Gerontology, found that elevated serum levels of various vitamin E forms was associated with decreased risk of development of cognitive impairment. Vitamin E is a fat-soluble vitamin in eight forms, four tocopherols and four tocotrienols and is an important anti-oxidant. To date one form, α-tocopherol , which is found in many vitamin E supplements, has been focused on in studies of cognitive impairment and Alzheimer's disease. However the Finnish study suggests that other forms of vitamin E, including γ-tocopherol, β-tocotrienol and total tocotrienols, are associated with the observed protective effect.

    The study focused on a sample of 140 Finnish people over the age of 65 who had no memory impairment at the beginning of the 8-year study. The study population was drawn from participants in the more extensive Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) study, which examines links between cardiovascular disease and memory impairment. For the purposes of the study, cognitive impairment was defined as development of mild cognitive impairment (MCI) or Alzheimer's dementia. Lower risk of cognitive impairment was observed in subjects with higher absolute serum levels of γ-tocopherol, β-tocotrienol, and total tocotrienols. The study highlights the importance of considering all forms of vitamin E when considering vitamin E status and suggests a further benefit of including vitamin E in the diet.

    The analysis of polyacrylamide gels is currently carried out manually or automatically. In the automatic method, there are limitations related to the acceptable degree of distortion of lane and band continuity. The available software cannot deal satisfactorily with this type of situations. Therefore, the paper presents an original image analysis method devoid of the aforementioned drawbacks.

    http://www.biomedical-engineering-online...nt/12/1/68

    It is possible to carry out this method of DNA polymorphism analysis on distorted images of polyacrylamide gels. The method is fully automatic and does not require any operator intervention. Compared with other methods, it produces the best results and the resulting image is easy to interpret. The presented method of measurement is used in the practical analysis of polyacrylamide gels in the Department of Genetics at the University of Silesia in Katowice, Poland.

    Research published in last week's Nature Communications suggests that the microRNA miR-181a may be a useful prognostic marker for predicting response to therapy of epithelial ovarian cancer (EOC). The study, from research groups in Case Western Reserve University and Mount Sinai Medical Centre, both in the USA, and the Mario Negri Institute of Pharmaceutical Research in Milan, examined expression of miR-181a in 80 human EOC samples. They also used both in vitro and preclinical in vivo ovarian mouse models to elucidate function and pathways of miR-181a. According to Analisa DiFeo of Case Comprehensive Cancer Center and lead investigator on the study, their findings showed that “miR-181a was one of the top expressing microRNAs in tumours from patients who recurred within the first six months after treatment" and that there were “higher levels in recurrent tumours compared to primary tumours" in their patient population.

    MicroRNAs such as miR-181a are short, single stranded RNA molecules which help control expression of up to 60% of all protein encoding genes. In the current study, in vivo and in vitro studies indicated that the target for miR-181a was the Smad7 gene. SMAD7 protein is an inhibitor of the TGF-β signalling pathway, a potent metastases inducer. Inhibition of SMAD7 by miR-181a would therefore remove the brake on TGF-β and encourage metastases.

    However, the story of miR-181a in cancer is not straightforward, and it appears to have more than one target protein, suggesting caution should be applied in any consideration of miR-181a in EOC therapy. MiR-181a has been associated with poor prognosis in colorectal cancer (CRC) and enhances the chemoresistance and resistance to radiation of human cervical squamous cell carcinoma. In contrast, in breast cancer decreased serum miR-181a has been proposed as a potential biomarker and miR-181a has been shown, for example, to enhance drug sensitivity in mitoxantone-resistant breast cancer cells. In this case, the target for miR-181a is the breast cancer resistance protein (BCRP/ABCG2). On the other hand, the target in CRC was expression of the tumour suppressor, phosphatase and tensin homolog (PTEN) while in human cervical squamous cell carcinoma cells it targeted the apoptosis inhibitor PRKCD.

    Given the number of targets for miR-181a that have been identified in various cancer cells and the differing effects of the microRNA in breast cancer as opposed to ovarian, cervical and colorectal cancer, a lot of work lies ahead in any potential therapeutic use of miR-181a. This is particularly relevant, for example, for women with hereditary breast–ovarian cancer syndromes. However, the study in Nature Communications does suggest a prognostic value for miR-181a in predicting response to therapy and recurrence for EOC.

    A flu forecasting website for the United States set up by infectious disease experts at Columbia's Mailman School of Public Health may help “foster greater awareness of influenza activity and risk around the country, and motivate individuals to take measures, such as vaccination, to protect themselves against the virus" according to Jeffrey Shaman, PhD, who led the site’s development. The URL is cpid.iri.columbia.edu. The system reports predictions every Friday during the flu season for 94 US cities.

    The latest data reported was for the week from December 29th 2013 to January 4th 2014. It reported in which cities flu was expected to arise and when it would peak and also in which cities seasonal flu is likely to have already peaked. Overall, the system predicted that the 2013-2014 flu season would peak later with fewer cases than in 2012-2013 but with considerably more severe cases than in 2011-2012 season.

    According to a press release from Colombia, the website boasts features including:
    • Interactive map of the United States the displays the relative severity of seasonal flu in cities across the country flu and incidence numbers for each.
    • Influenza incidence predictions by city for the coming weeks.
    • Map that illustrates the proportion of flu cases by region.
    • Charts that compare the timing and severity of the four most recent flu seasons.
    • Exportable data for each week of the flu season (beginning in 9/29 for the 2013-2014 season).

    The scientifically validated system adapts techniques used in weather forecasting to convert real-time, Web-based estimates of influenza infection into local forecasts of the future influenza incidence by locality. It is hoped that access to the website may have a positive public health impact by influencing the public in terms of accessing vaccination and exercising care around people sneezing and coughing. It should also have a positive impact on public health officials by helping inform decisions on vaccine stockpiling and distribution and measures such as school closures. It is to be hoped that in the future this type of system may become available internationally.

    Researchers from KU Leuven in Belgium have identified a ‘short-circuit’ mechanism in chemosensors called transient receptor potential (TRP) channels that can paradoxically lead to increased pain in response to candidate painkillers targeting these channels. The work, published online in last week’s Nature Chemical Biology focused on one member of the TRP family called TRPM3.

    Pain provides with a vital ‘warning’ system alerting us to the dangers of, for example, extreme heat or cold. A network of sensory nerves, for example in the skin and mucosa, relays pain signals from around the body to the brain. Around these nerves are ion channels such as the TRP family. The TRP family act as primary chemosensors. Upon binding of a ligand, a cation conducting pore opens in the middle of the TRP channel. This results in a tiny electrical signal which when it is transmitted to the brain is interpreted as pain. The Belgian group’s work involved study of candidate painkillers which would target the TRPM3. This channel detects heat and the hormone pregnenolone sulfate, a pain and inflammation trigger. TRPM3 can be gated by combinding drugs such as endogenous neurosteroids and exogenous chemicals such as clotrimazole.

    In an in vivo mouse model, the Belgian study found that an alternative pathway was mediated via TRPM3 when channels were closed by a number of different mechanisms including desensitization, blockade, mutagenesis and chemical modification of the central pore. This pathway therefore did not depend on an open ion channel. Instead, it involved a ‘short circuit’ whereby the stimulus found a different route; rather than using the central pore, it carved a path through the surrounding material and activated the nearby pain nerves, sending a pain signal to the brain. The overall result was to exacerbate TRPM3-dependent pain. The researchers maintain that this mechanism may explain the pain-enhancing side effects of drugs such as clotrimazole and thy hope that it will shed new light on TRP channel function and pharmacology.

    Studies on the white-throated sparrow have given a rare insight into how a chromosomal rearrangement resulting in genetic polymorphism directly impacts behaviour in a vertebrate. The study, led by researchers in Emory University, was published in early edition this week in the Proceedings of that National Academy of Sciences in the United States of America (PNAS). It has linked differences in parenting and aggression behaviour in two different white-throated sparrow phenotypes to the oestrogen receptor ER-alpha.

    The PNAS study examined white-throated sparrows (Zonotrichia albicollis) with two different, long-recognised phenotypes caused by a rearrangement in a chromosome sequence known as chromosomal polymorphism ZAL2/2m. This polymorphism results in two readily distinguishable forms of the sparrow, the tan-striped morph and the white-striped morph, respectively. The attached picture clearly shows how they can be distinguished by their plumage (copyright/credit Brent Horton, http://esciencecommons.blogspot.ie/2014/...ial.html). Sparrows with the rearranged ZAL2m polymorphism (white-striped) are recognised to be more aggressive and less parental than the tan-striped birds.

    In the study, parenting behaviour was assessed in the wild by monitoring frequency with which the birds returned to the nest to feed their young while aggression monitoring was based on analysis of song rate in the presence of a perceived threat to the sparrow’s territory. Such patterns of behaviour are thought to be mediated by sensitivity to sex steroids in vertebrates. An examination of the polymorphic region revealed various candidate genes, among them ESR1, the gene for oestrogen receptor ER-alpha. Levels of expression of this receptor affect sensitivity to sex hormones including testosterone. The study demonstrated that in the region of the ESR1 gene that controls its expression, known as the promoter, there were fixed differences (polymorphisms) between the tan-striped and white-striped birds. These polymorphisms affected the transcription of ESR1 in vitro. When expression of the ESR1 protein product, ER-alpha, was examined in brain regions associated with aggression, white-striped birds (the more aggressive ZAL2m polymorphism type) had three times the level of ER-alpha than the tan-striped birds. By correlating behavioural data and lab data, the researchers were able to show that expression of ER-alpha in that region and others predicted variation in territorial aggression and parenting.

    This is an unusual example of a study being able to demonstrate directly how a chromosomal rearrangement causes behavioural difference in a vertebrate. The authors are currently examining a suite of further neuroendocrine genes captured by the chromosome rearrangement to examine their impact on behaviour.

    A study led by a research group in the University of Washington has found that inherited (germline) mutations in genes known to be involved in ovarian cancer are present in 20% of women with no known family history or predisposition to ovarian cancer. The study, published yesterday in Nature Communications, also revealed the presence of germline mutations in genes not previously associated with ovarian cancer. The results of this study suggest that screening of women for ovarian cancer needs to take into account the fact that genetic susceptibility to ovarian cancer may not be obvious from a look at family history. While more than 20000 women are estimated to be afflicted with ovarian cancer, often it is not diagnosed until the cancer has spread due to a lack of definitive symptoms. As a result, there is a poor five –year survival rate for this cancer. The germline mutations identified in this study may not in themselves necessarily lead to cancer, however when linked to acquired (somatic) genetic changes that may occur during a woman’s life, these germline mutations would be sufficient to tip the balance. The authors consider the 20% figure to be conservative as on-going research is expected to reveal further mutations.

    The study used large-scale exome-wide analysis to examine both tumour DNA and the woman’s own DNA from 429 ovarian carcinoma cases and 557 controls. These ovarian cancer cases were considered to have arisen sporadically, in the absence of any known familial susceptibility. By comparing the sequences, the researchers were able to identify the somatic mutations that had been acquired in the tumour. In addition, they could compare the ovarian cancer patients’ own DNA samples to those of control subjects to determine if there were germline variants in the cancer patients related to susceptibility to ovarian cancer. This genetic detective work revealed that in 20% of these apparently sporadic ovarian cancer cases, there were germline truncation variants and large deletions in genes belonging to the Fanconi pathway. This pathway is associated with cell division and repair of damaged or mutated DNA and includes the genes BRCA1 (breast cancer type 1 susceptibility protein) and BRCA2 (breast cancer type 2 susceptibility protein), which are widely known to be associated with predisposition to both ovarian and breast cancer. The study found that the ovarian cancer patients carried germline mutations in these genes which would lead to shortened (truncated) protein product, as well as mutations in another gene in this pathway, PALB2 (Partner and localizer of BRCA2). As well as these mutations which were already familiar in the field of ovarian cancer susceptibility, mutations were found in several other genes not previously known in this context, including NF1 (Neurofibromin), MAP3K4 (Mitogen-activated protein kinase kinase kinase 4), CDKN2B (Cyclin-dependent kinase 4 inhibitor B) and MLL3 (Histone-lysine N-methyltransferase 2C).

    In all, the findings of this important paper should encourage better integration of knowledge of both inherited and acquired mutations in causing ovarian cancer and contribute to changes in screening practices for this devastating disease. The lead author of the paper, Dr. Li Ding, said: “We’re now able to obtain a fuller picture of the way cancer develops in a particular patient. More studies are needed, but our findings could have important implications for developing better screening strategies for ovarian cancer and improving early detection.”
