In pursuit of efforts to advance research on viruses and disease control, the United States-based Centre for Disease Control and Prevention (CDC) has made a commitment to enhance the University of the Free State (UFS) Next Generation Sequencing (NGS) Unit’s data collection systems and further empower its staff and students.

UFS and US guests explore areas of mutual; cooperation

During a visit to the university in early December last year CDC delegation, Dr Michael Bowen and Dr Mathew Esona, a meeting was held with the lead Researcher at the UFS-NGS Unit, Dr Martin Nyaga; Senior Director of the UFS Directorate Research Development, Dr Glen Tylor; Director of UFS Office for International Affairs, Cornelius Hagenmeier; and Dr Saheed Sabiu Postdoctoral Research Fellow in the Faculty of Natural and Agriculture Sciences. It was in this meeting that areas of mutual collaboration and engagement between the two institutions which include technology transfer, funding and wet and dry laboratory quality control and capacity development were identified.

The UFS-NGS Unit, established in 2016, enjoys longstanding networking and collaborative ventures with renowned researchers in Africa, the USA, and Europe – which in return, have contributed immensely to the research activities of the university as a whole.

Dr Nyaga said in an effort to advance genomics research in the NGS Unit, the visitors have committed themselves to initiate and further enhance capacity development for the unit’s staff and students.

US guests impressed with advanced equipment at UFS

The CDC delegation were intrigued that the UFS also operates a Miseq Illumina platform like the one used at their enteric-viruses laboratory. It could thus be in line to assist in developing exclusive pipelines for the analysis of NGS data generated by the UFS-NGS Unit.

This is a personal sequencing system, which is a powerful state-of-the-art next-generation sequencer. It uses sequencing-by-synthesis technology capable of sequencing up to 15GB of high-quality filtered bases per run, with up to 600 base-pair read lengths. This allows the assembly of small genomes or the detection of target variants with unmatched accuracy, especially within homo-polymer regions.

UFS and CDC engagements still on

Further engagements about the identified areas of collaboration are ongoing between Hagenmeier, Dr Bowen, and Dr Nyaga, who are currently working on appropriate mechanisms to enact the envisaged collaboration between the two institutions.

The NGS Unit received research awards from the World Health Organisation, South African Medical Research Council, Poliomyelitis Research Foundation, and the National Research Foundation for different aspects of genomics research, and more recently from the Bill and Melinda Gates Foundation for the Enteric Viruses Genome Initiative, involving four African countries (South Africa, Ghana, Malawi, and Cameroon).

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
