Prof Carlien Pohl-Albertyn, a successful scientist, is living her dream job, as she gets to pursue her passion for microbiology; a career she wanted to pursue ever since Grade 10.

Prof Carlien Pohl-Albertyn, a professor of Microbiology in the Department of Microbiology and Biochemistry, is the holder of the SARChI Chair in Pathogenic Yeasts at the University of the Free State (UFS). She is leading the Pathogenic Yeast Research Group, studying pathogenic yeast infections and necessary treatment options and bringing hope to many immunosuppressed patients battling HIV/Aids, cancer, diabetics, and other diseases. She also recently co-authored an article on the incidence of fungal infections in COVID-19 patients. 

“This is my dream job, as I get to pursue my passion for microbiology,” says Prof Pohl-Albertyn, who already knew as early as Grade 10 that she wanted to become a microbiologist. “I have always been fascinated by the natural world and have known since childhood that I would become a scientist,” she says. 

An interview with Prof Pohl-Albertyn reveals more about the persons who inspired her, her view on the development of women, and how she approaches her work. 

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

“The first woman who instilled a love for the biological sciences in me was Miss Steyn, my high school Biology teacher. She had a passion for teaching that inspired me to become a microbiologist.”

Prof Pohl-Albertyn, however, states that there were many other women who constantly inspired her to be a better person. 

“My mother inspires me to take responsibility for my choices; my mother-in-law inspires me to be kinder to others; and my best friends’ mothers inspire me to persevere, even when things are difficult.”

“I am also inspired by my female friends, Ezelle van den Heever, who has shown me that there is always a plan to be made to solve a problem; Trudi O’Neill, who manages to balance high-level research, teaching, and administration with her home life; Alicia Sherriff, from whom I am learning to be more emotionally intelligent; and Janine Allen, who has expanded my horizons and regularly shows me how to look at the world in a completely different way.”

What is your response to current challenges faced by women and available platforms for women development?

“Coming from a fairly male-dominated cultural background, I realise that I have been very privileged to not experience challenges just because I am a woman. I have been able to study and work in a field that values women and men equally and have chosen a very capable and extremely supportive husband, who sees me as an equal.”

She, however, realises that this is not the case for many women, and understands that there are women who were not able to follow their dreams and make their own life choices.

Prof Pohl-Albertyn believes that any opportunity for women to overcome challenges should be encouraged, as a society will ultimately be better if everyone is able to fulfil their greatest potential.

What advice would you give to the 15-year-old you?

This successful scientist, spouse, mother of two sons, daughter, friend, and mentor to many, says that she will advise her 15-year-old self to do everything the way that she has been doing it. “I do not regret anything and would not change my life in any way,” she says. 

What would you say makes you a woman of quality, impact, and care?

“I am a person of quality because of my integrity, work ethic, and commitment to my responsibilities – something that is easy if you enjoy what you do every day.”

“I am a person of impact because of the influence I have on my colleagues, who I always treat with respect, and my students, who I teach to the best of my abilities, and which I hope will serve them well in their careers.”

“I am a person of care because I value the contributions of my colleagues and students to my own growth and development,” remarks Prof Pohl-Albertyn.

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.
