University of Limpopo visits UFS Protection Services
Staff from the University of the Free State Department of Protection Services pictured with the delegation from the University of Limpopo during their benchmarking visit.

The University of the Free State Department of Protection Services hosted a delegation from the University of Limpopo on Friday, 13 May 2022 as part of benchmarking best protection service practices. 

During the visit, discussions included the management of student protests, gender-based violence, fire emergency responses, and challenges experienced with the Campus Protection Society of Southern Africa.

The visit by the University of Limpopo follows similar benchmark visits by the Central University of Technology, Sol Plaatje University, and the University of Johannesburg.

Noko Masalesa, Senior Director: Protection Services, said: “The visit by the University of Limpopo was used to take them through our vision 2024, to show them some of the advanced CCTV cameras that the UFS has installed, the policies, and organisational structure. Part of that strategy is to enhance the university’s security technology in line with the best practices.”

Masalesa said: “The UFS has a good model to manage all the different functional areas of the Department of Protection Services, and most universities are impressed with the new CCTV cameras that we rolled out and the other advances made in the development of protection services over the past five years.”

To remain among the leaders in protection services within the higher education, the department also visited Stellenbosch University, the University of Cape Town, Cape Peninsula University of Technology, and the University of Nairobi and Kenyatta University – both in Kenya.

Mampuru Mampa, Director: Safety and Security at the University of Limpopo, said: “Like other institutions, the University of Limpopo is dealing with crimes affecting students on and off campus, as well as student protests. Fostering collaboration and benchmarking will assist our protection service departments to develop and implement a standardised approach to improve safety on our campuses.”

On lessons learnt during the benchmarking tour, Mampa said: “We have learnt about security system integration, investigation systems approach, off-campus security, and student protest management.”

Mampa believes “it is important for protection service departments across the higher education sector to develop standardised security measures to improve safety, and benchmarking assists in closing gaps in protection services”.

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.
