Knock-in continues quest for diabetes cure

KO mouse

Diabetes is a major health challenge worldwide and understanding the disease is the focus of intensive research for many scientists and institutions. Despite the prevalence of diabetes and the substantial body of knowledge on the mechanisms of insulin synthesis and secretion, scientists have not yet identified a specific cause, and are yet to find a cure.

Prof. Peter Shepherd and Dr. Brie Sorrenson from the Department of Molecular Medicine and Pathology at the University of Auckland, New Zealand, are conducting research into instruments that are involved in diabetes and the development of new treatment therapies.

Insulin secretion occurs in the pancreatic beta-cells in response to glucose levels and is regulated at both the transcriptional and translational level. The cis-acting sequences within the 5′ flanking region and trans-activator genes regulate transcription, and the stability of preproinsulin mRNA and its untranslated regions control protein translation. Secretion is regulated by various hormones, such as melatonin, estrogen, leptin, growth hormone and glucagon.

There is evidence that genetic and environmental factors can lead to conditions that functionally compromise beta-cells resulting in the pathogenesis of diabetes, and recent research has been focused on the importance of insulin gene mutations at the transcriptional level in our understanding of beta-cell biology.

Prof. Shepherd and Dr. Sorrenson’s recent research has identified that the transcription co-activator beta-catenin, involved in the Wnt (Wingless-related integration site) signaling pathway, is regulated by glucose. Specifically, glucose regulates the phosphorylation of this protein at residue Serine 552.

A knock-in mouse model has been developed by Ozgene with an Alanine which cannot be phosphorylated to replace Serine 552. This model will allow Dr. Shepherd and Dr. Sorrenson to determine the role of beta-catenin phosphorylation in glucose stimulated insulin secretion and whole body glucose homeostasis. The results will provide insight into an important mechanism involved in diabetes development and thus contribute to our knowledge of the causes of the disease, and the development of new therapies. Prof. Shepherd and Dr. Sorrenson’s research will also provide a platform to investigate the importance of beta-catenin Serine 552 phosphorylation in multiple other physiological processes.

Shingo International Conference

Our CEO, Dr Frank Koentgen, is attending the Shingo International Conference in Washington DC, 25-29 April. The conference is all about organisational improvement beginning with an organisation’s culture and ending with results. Join other like-minded leaders and managers to hear from professionals who have turned organisations around. They will share details of the steps they took to success.

You can also attend the actual Shingo Workshops of your choice and see how you can begin to shape your organisation’s culture to make it the envy of your industry.

Frank's blog - Order within chaos

Think about a water particle in the ocean. Look at it on its own and you can't see much potential, but when a wave forms you can see a greater pattern emerge from the behaviour of many small particles. This is emergence. It lets us explore how we might grow and change into new areas. As an organisation, we want to exist in the space known as the edge of chaos, where there is maximum creativity, potential and adaptability but also stability.
