The University of the Free State – Next Generation Sequencing (UFS-NGS) Unit hosted a pioneering scholarly engagement initiative for Grade 11 learners from nine secondary schools in Bloemfontein. The three-day event with the theme "Frontiers of Discovery: Illuminating the Impact of Genomics in Science outreach programme” marked the first comprehensive genomics science outreach initiative in the Faculty Health Sciences.

Coordinated by Prof Martin Nyaga, Head of the UFS-NGS Unit, the programme bridged the longstanding gap through practical NGS exposure and ignited a passion for Science, Technology, Engineering, and Mathematics (STEM) by inspiring the next generation of genomic innovators using combined interactive lectures, laboratory demonstrations, career talks, and hands-on workshops. This allowed learners to directly engage with cutting-edge scientific techniques and genomic technologies, especially the scientific and evolutionally impact of Polymerase Chain Reaction (PCR) and NGS.

The initiative engaged selected Grade 11 learners from the nine schools: Brebner, Ikaelelo and Vulamasango (day 1), Atlehang, Castle Bridge School and Kaelang (day 2) and Eunice, Navalsig, and Lekhulong (day 3).

“This outreach programme marks a significant milestone in community-based genomics education in South Africa by offering high school learners the opportunity to engage with modern genomic sciences before making career decisions. The initiative particularly aimed to nurture future scientists and diversify the country’s STEM talent pipeline.

“This historic programme bridged gaps in scientific literacy and diversity in the Free State and concluded each day with a genomics quiz competition, which tested the participant’s newly acquired knowledge/exposure and provided a fun competitive learning opportunity. Six quiz winners across the three days received special prizes, and all students were awarded certificates of participation,” says Prof Nyaga.

 

Hands-on exploration and NHLS virology laboratory tour

The training was held at the UFS-NGS Unit in the School of Biomedical Sciences and at the NHLS Virology laboratories, School of Pathology, Faculty of Health Sciences. Each attending secondary school was represented by five Grade 11 learners and a life science’s educator. Each day, 15 learners and three educators observed hands-on practicals, including DNA extraction, PCR, gel electrophoresis, and DNA library preparation for sequencing on platforms such as Illumina MiSeq and NextSeq 2000.

Guided by the UFS-NGS Unit’s team members; Dr Milton Mogotsi, Hlengiwe Sondlane, Mbali Ncube, Nkosazana Shange, Somila Nazo, Sesiyanda Maseko, Surprise Baloyi, Manyi Eyong and Mamello Maku, the learners were exposed to how DNA is extracted and visualised, how the PCR machine works and how DNA libraries are prepared and sequenced.

Furthermore, a guided laboratory tour of the Virology laboratories at the NHLS was provided by Khauhelo Mafa which offered the leaners the opportunity to observe, diagnostic and molecular workflows in action, resulting in a real-time glimpse into world-class medical research and diagnostics, fuelling curiosity about the role of advanced genomics science in disease control.

 

Inspiration through expert talks

The learners were also inspired by talks from Prof Chris Viljoen, Head of the School of Biomedical Sciences, Prof Zinhle Makatini, Associate Professor and Head of Division of Virology, School of Pathology, and Dr Claudia Ntsapi, Senior Lecturer and researcher in the Department of Basic Medical Sciences at the UFS. Prof Viljoen highlighted the role of science in transforming lives and improving life expectancy, while Prof Makatini gave candid reflections on her professional journey, particularly how she pursued Medical Virology through unwavering determination and excelled to become among the pioneer women specialists in the field in South Africa. Dr Ntsapi inspired the audience with her perseverance from her humble beginnings to earning a PhD in Neurophysiological Sciences against all odds.

The speakers also delivered compelling presentations on the applications of genomics in medicine (e.g.), personalised cancer treatments), public health (e.g.), tracking HIV and COVID-19), agriculture (e.g.), resilient crops), and environmental science (e.g.), ecosystem protection), which resonated well with the learners, educators and the UFS-NGS team. A presentation on diverse career options available at the UFS Faculty of Health Sciences was further provided by Angelique Carson-Porter, a UFS representative from the Department of Nutrition & Dietetics. Her talk on different career pathways in Health Sciences broaden the learners’ horizons, fostering future aspirations.

Dr Emmanuel Ogunbayo, Dr Mogotsi, Thabisa Mpaxa, Nkosazana Shange and Eyong Manyi shared their personal career journey to be at the UFS-NGS Unit, offering advice on academic experiences and opportunities within genomics, bioinformatics, and biotechnology, while answering scholarship queries.

“The career talk opened my eyes. I’m now aiming for a biotechnology degree!” said Neliswa Thwala, a learner from Navalsig CS/S.

Following the enthusiastic response and tangible outcomes of this programme, the UFS-NGS Unit is committed to expanding this initiative, with plans to introduce similar events to other schools and developing sustained mentorship opportunities for learners interested in pursuing genomics-related careers. The UFS-NGS Unit further invites interested partners, sponsors, and stakeholders to collaborate in future outreach and capacity-building programmes to continue bridging the genomics education gap in Africa.

 

Inspire the next generation

Prof. Nyaga’s closing remarks highlighted the learners’ potential to shape the ‘omics’ workforce and stated the intention of the organising committee to expand the mentorship programmes, fostering a vibrant STEM pipeline. “This initiative represents our vision to make genomics accessible and inspire the next generation of African scientists.”

The success of this programme was driven by the UFS-NGS Unit team and was supported by Distribution Platform in Omics (DIPLOMICS).

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
