Prof Motlalepula Matsabisa, Associate Professor in the Department of Pharmacology at the University of the Free State (UFS), has been appointed as the chairperson of the World Health Organisation’s (WHO) Regional Expert Advisory Committee on Traditional Medicines for COVID-19.

Prof Motlalepula Matsabisa, Associate Professor in the Department of Pharmacology at the University of the Free State (UFS), will lead Africa’s fight against the COVID-19 pandemic with his appointment as chairperson of the World Health Organisation’s (WHO) Regional Expert Advisory Committee on Traditional Medicines for COVID-19.

Prof Matsabisa has been chosen over 25 other experts from 27 African countries to head this expert committee tasked with setting up research and clinical trials for COVID-19 and beyond. The committee is also supported by the African Union (AU), the Centers for Disease Control and Prevention (CDC – Africa), and the European and Developing Countries Clinical Trials Partnership (EDCTP).

This committee was established by the WHO and the Africa CDC on 22 July with the aim of providing independent scientific advice and support to countries on the safety, efficacy, and quality of traditional medicine therapies. It is also an effort to enhance research and development of traditional medicines for COVID-19 in Africa.

Looking forward

“This is a huge continental and global responsibility being laid on my shoulders as a chairperson.  I have to keep the committee together and ensure that it delivers on its set mandate and terms of reference.  I need to ensure that the committee helps the continent and region to get the scientific and legislative aspects on traditional medicine development on track.”  

“I have taken this position and responsibility, knowing quite well what it entails. I want to do this for the continent and for the sake of good science of all traditional healers and consumers of traditional medicines on the continent and beyond,” says Prof Matsabisa.

According to Prof Matsabisa, he is looking forward to working with a team of dedicated experts from 27 countries in the African region, and being of help to countries that need assistance with clinical trials, including preclinical work to move to clinical research.

Prof Matsabisa says he is also looking forward to countries asking South Africa to be part of their multi-centre studies in clinical trials for traditional medicines, and to help set up clinical trial teams that include Western-trained clinicians to get into traditional medicine studies. 

The work of the committee

According to Prof Matsabisa, his new position took effect the same day as his appointment and will run as long as COVID-19 is part of our daily lives and even beyond. It entails supporting member states to implement the WHO master plan for clinical trial protocols in order to generate credible data for COVID-19 results, based on traditional medicines. The committee will also coordinate support to member states in the African region to collaborate on clinical trials of traditional medicine-based therapies – elevating standards by pooling expertise in multicentre studies, as well as complying with GCP and good participatory practice guidelines for trials of emerging and re-emerging pathogens.
“The committee will also advise on strengthening the capacity of national medicine regulatory authorities to accelerate the issuance of marketing authorisations for traditional medicine products that have been well researched for safety, efficacy, and quality, as well as to expedite the approval of clinical trials on traditional medicines. This will help to meet the national registration criteria and the WHO norms and standards of quality, safety, and efficacy for the management of COVID-19 and others.”

“It will also provide independent scientific advice to the WHO and other partners regarding policies, strategies, and plans for integrating traditional medicines into COVID-19 responses and health systems,” explains Prof Matsabisa. 

Aiming for the top spot 

Prof Matsabisa has been described as having the third highest research output – something he is not satisfied with. 
“I was disappointed that only one point separated me from the second place. I will push for first place as this is my ultimate aim. My motivation for this is simple – I like what I am doing, I do not take it as a job but do it because I love research.”  

“I always like to tell students that we should be proud to one day see products in the shops that we can relate to and to which we have contributed or that we have made.   This is what drives me and my staff.  I have a beautiful team of students, staff, and postdoctoral fellows who share my vision of research.  We all have a shared vision and strive to be relevant at all times in science research, development, and teaching.”

• Prof Matsabisa was recently part of a national conference with the theme: Harnessing science, technology, and innovation in response to COVID-19: A national and international effort. The conference was hosted by Dr Blade Nzimande, Minister of Higher Education, Science and Innovation, with Pres Cyril Ramaphosa, Dr Zweli Mkhize, Minister of Health, Ebrahim Patel, Minister of Trade, Industry and Competition, Prof Sarah Anyang Agbor, African Union Commissioner for Human Resources, Science and Technology, and Dr Tedros Adhanom Ghebreyesus, Director-General of the World Health Organisation, in attendance.

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.
