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).

To tan or not to tan: a burning issue

2009-12-08

Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
