Heritage Day

Staff members of the Faculty of Health Sciences working in the Muller Potgieter Building celebrated Heritage Day on Thursday (23 September 2021) by feasting together on different traditional meals and enjoying their diverse cultural backgrounds.

For Ms Rejoyce Ncube, an Assistant Officer in Undergraduate Medical Programme Management, Heritage Day is an important reminder of who we are as South Africans. She has been wearing different cultural attire since the start of Heritage Month.

“I love wearing different attires. It is so unique and colourful.  It is also important because, when you look at the young people, they do not always know the difference between the cultures.

“As much as I am Zulu, I wear attires from different cultures. I need Tsonga and Ndebele attire.  It is just to make people aware that we are all South African and also to teach the young people that they have a history behind who they are. I love the uniqueness, the colours, and the designs,” says Ncube.

Heritage Day important to teach young people about different cultures in South Africa
According to her, Heritage Day is important to teach young people about the different cultures in South Africa and the history behind them. Ncube says she also tries to cook a traditional African dish for her family every Sunday.

Ms Joyce Phindela, an Assistant Officer in the School of Clinical Medicine, says Heritage Day helps her to remember who she is and where she comes from. Says Joyce: “I am Xhosa, but mostly grew up in the Sotho and Coloured community and I went to an all-Afrikaans school. This is what is meant by being South African and what makes us unique.”

“Heritage Day gives me an opportunity to represent who I am and to teach other people about my culture. I also get to learn from other people and their cultures, because on a normal day we do not learn from each other. I can teach this to my kids one day.”

Some of the traditional treats shared included dombolo, samp and beans, droëwors, koeksisters, and melktert.

Dr Lynette van der Merwe, Undergraduate Medical Programme Director in the School of Clinical Medicine, indicated that the staff working in the Muller Potgieter Building consider themselves part of a diverse, multicultural, multilingual family who try to make one another’s lives enjoyable by being friendly, courteous, supportive, and kind.  Sharing and learning from one another and realising that we all have unique stories to tell about our varied backgrounds bring us closer together and help us grow in unity.

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.
