13:00 - SEMINAR - Cardiodegeneration and the paradoxical response of the antioxidant response protein Nrf2 : School of Human Sciences (APHB) Seminar Series More Information
Speaker: Professor Des Richardson holds the Chair of Cancer Cell Biology at the University of Sydney, Australia, and is a National Health and Medical Research Council (NHMRC) of Australia Senior Principal Research Fellow. He has published > 407 articles, reviews, patents, chapters etc., over his career with >93% as first, senior or corresponding author (H-index: 80; >24,255 citations over entire career; with >13,750 citations over the past 5 years and H-index: 55 over past 5 years: Google Scholar Accessed 10 Jan, 2018). He is Executive Editor of BBA-General Subjects and has served on the Editorial Boards of >40 international journals, including J. Biol. Chem., Antioxidants Redox Signaling, Biochem. J., BBA-Mol Cell Res, Mol. Pharmacol., Pharmacol. Res., etc. As a major translational research achievement, he has developed the anti-cancer and anti-metastatic drug, DpC, which overcomes P-glycoprotein mediated drug resistance. This has led to commercialisation of DpC and the development of the international company, Oncochel Therapeutics LLC, USA and its Australian subsidiary, Oncochel Therapeutics Pty Ltd. Notably, DpC has entered multi-centre Phase I clinical trials for the treatment of advanced and resistant cancer. Abstract: Nuclear factor-erythroid 2-related factor-2 (Nrf2) is a master regulator of the antioxidant response. However, studies in models of Friedreich ataxia, a neurodegenerative and cardiodegenerative disease associated with oxidative stress, reported decreased Nrf2 expression attributable to unknown mechanisms. Using a mouse conditional frataxin knockout (KO) model in the heart and skeletal muscle, we examined the Nrf2 pathway in these tissues. Frataxin KO results in fatal cardiomyopathy, whereas skeletal muscle was asymptomatic. In the KO heart, protein oxidation and a decreased glutathione/oxidized glutathione ratio were observed, but the opposite was found in skeletal muscle. Decreased total and nuclear Nrf2 and increased levels of its inhibitor, Kelch-like ECH-associated protein 1, were evident in the KO heart, but not in skeletal muscle. Moreover, a mechanism involving activation of the nuclear Nrf2 export/degradation machinery via glycogen synthase kinase-3β (Gsk3β) signaling was demonstrated in the KO heart. This process involved the following: i) increased Gsk3β activation, ii) β-transducin repeat containing E3 ubiquitin protein ligase nuclear accumulation, and iii) Fyn phosphorylation. A corresponding decrease in Nrf2-DNA-binding activity and a general decrease in Nrf2-target mRNA were observed in KO hearts. Paradoxically, protein levels of some Nrf2 antioxidant targets were significantly increased in KO mice. Collectively, cardiac frataxin deficiency reduces Nrf2 levels via two potential mechanisms: increased levels of cytosolic Kelch-like ECH-associated protein 1 and activation of Gsk3β signaling, which decreases nuclear Nrf2. These findings are in contrast to the frataxin-deficient skeletal muscle, where Nrf2 was not decreased.

16:00 - SEMINAR - Mathematics and Statistics Colloquium : Mathematics and the Noise Immunity of the Genetic Code More Information
Symmetry is one of the essential and most visible patterns that can be seen in nature. Starting from the left-right symmetry of the human body, all types of symmetry can be found in crystals, plants, animals and nature as a whole.

Similarly, principals of symmetry are also some of the fundamental and most useful tools in modern mathematical natural science that play a major role in theory and applications. As a consequence, it is not surprising that the desire to understand the origin of life, based on the genetic code, forces us to involve symmetry as a mathematical concept.

The genetic code can be seen as a key to biological self-organisation. All living organisms have the same molecular bases - an alphabet consisting of four letters (nitrogenous bases): adenine, cytosine, guanine, and thymine. Linearly ordered sequences of these bases contain the genetic information for synthesis of proteins in all forms of life. Thus, one of the most fascinating riddles of nature is to explain why the genetic code is as it is.

Genetic coding possesses noise immunity which is the fundamental feature that allows to pass on the genetic information from parents to their descendants. Hence, since the time of the discovery of the genetic code, scientists have tried to explain the noise immunity of the genetic information. In this talk we will discuss recent results in mathematical modelling of the genetic code with respect to noise immunity, in particular error-detection and error-correction.

13:00 - SEMINAR - Losing excess body weight or fat without losing strength or lean tissues : School of Human Sciences Seminar Series Website | More Information
While reducing excess body weight or fat is important for certain athletes and for the treatment of overweight and obesity, it is essential that weight loss interventions do not result in losses of physical strength or lean tissues such as muscle and bone, any of which could impair physical abilities and increase the risk of structural diseases such as sarcopenia or osteoporosis.

A dietary intervention showing potential for reducing body weight and fat without excessive loss of lean tissues is a novel form of intermittent energy restriction (IER) entailing repeated cycles on a moderately kilojoule-restricted diet for 2-4 weeks, interspersed with 2-week periods of energy balance, where kilojoule intake is matched to energy requirements and weight is maintained. In a randomized controlled trial of 51 men with obesity, this form of IER significantly improved weight and fat loss compared to continuous energy restriction (CER): weight loss 14.1 ± 5.6 versus 9.1 ± 2.9 kg; fat loss 12.3 ± 4.8 versus 8.0 ± 4.2 kg; means ± SD, P<0.01 for both comparisons), with no difference in loss of fat free mass (1.8 ± 1.6 versus 1.2 ± 2.5 kg; P = 0.4)1.

Another dietary intervention with potential for body weight and fat loss without excessive loss of strength or lean tissues in people with overweight or obesity is – paradoxically – fast weight loss, achieved via total meal replacement diets. The TEMPO Diet Trial (ACTRN12612000651886) has shown that at 1 year after commencement of a diet involving either fast or slow weight loss in postmenopausal women with obesity, there was no difference between diets with respect to muscle (handgrip) strength, fat free mass or bone mineral density, despite the fact that women on the fast diet lost almost twice as much weight and fat as women on the slow diet (16.9 ± 7.1 versus 9.7 ± 7.5% of body weight, and 11.1 ± 5.6 versus 6.1 ± 5.5 kg of fat mass; P<0.001 and P<0.05, respectively).

In light of the greater weight and fat loss achieved using IER as opposed to CER, as well as the lack of apparent deleterious effect of fast versus slow weight loss on muscle strength or lean mass despite markedly greater weight and fat loss, an NHMRC-funded randomised controlled trial, commencing 2018, aims to determine whether greater weight and fat loss – without greater loss of strength or lean tissues – can be achieved via intermittent use of fast weight loss in adults with overweight or obesity. If yes, then determining the mechanisms for any potential advantage of IER over CER (e.g. via reduced energy efficiency as a result of switching between carbohydrate and lipid or ketone oxidation in skeletal muscle) could enable IER interventions to be further improved. Moreover, future work to determine whether/how physical activity improves weight loss outcomes from IER (e.g. via attenuation of the drive to eat as a result of greater lean mass retention) could provide motivating reasons for people with overweight or obesity to exercise during weight loss interventions.

Biography

With a Bachelor of Science from the University of Western Australia and a PhD from the University of Geneva, Switzerland, Professor Amanda Salis (publishing as Sainsbury) leads full-time research into dietary treatments for overweight and obesity at the University of Sydney’s Boden Institute of Obesity, Nutrition, Exercise & Eating Disorders in the Charles Perkins Centre. Her translational research into hypothalamic control of appetite, eating behavior, energy expenditure, body weight and body composition spans transgenic mice, adults with overweight or obesity, as well as adult athletes. Her randomized controlled trials comparing long-term effects of fast versus slow weight loss – using intermittent versus continuous energy restriction – are funded by a Senior Research Fellowship and Project Grants from the National Health and Medical Research Council (NHMRC). She is the author of two books about adult weight management that are available internationally in three languages and are used by consumers, community health centres / gyms, and by healthcare professionals (e.g. general practitioners, physiotherapists, dieticians, diabetes educators and psychologists).
