Oncopig Model for Cancer Research

Oncopig  Cancer Model: A New Approach in Cancer Research for Humans

By Ramadhani Chambuso

Oncopig Cancer Model is a novel transgenic swine model that recapitulates human cancer through the development of site and cell specific tumors. For decades, cancer research progress has been markedly hampered by the lack of a phenotypically, genotypically, anatomically, and physiologically relevant large animal models.

On the other hand, small animal models, such as mouse models, have played a major role in our understanding of the genetic basis of cancer and the role of specific genes and gene mutations in the development and progression of cancer. However, due to vast differences between humans and rodents or zebrafish for example, the ability to model complex diseases such as cancer and translate results into clinical practice is quite limited

In a nutshell, large animal models of cancer comprise a smaller portion of cancer models than small animal cancer models. Therefore, these large animal models recapitulate transcriptional hallmarks of the human disease while also exhibiting clinically relevant histologic and genotypic tumor phenotypes.

Breast Cancer Screening using Mammography

Breast Cancer Screening with Mammography in Women Aged 40-49 Years is Still Controversial

By Ramadhani Chambuso

The incidence and mortality rates from breast cancer are expected to rise as a result of the ageing population. To reduce the burden of this disease, many countries have implemented mammography screening for early detection and treatment of breast cancer for all women aged from 50 years for every 2 years. However, there is a debate about whether breast cancer screening should be extended to younger women (i.e., 40–49 years). Generally, for effective cancer screening programme, the benefits should outweigh the harms. Some negative effects of breast cancer screening include radiation exposure from mammography, pain during the mammography procedure, consequences of false positive and false negative tests, and the occurrence of over-diagnosis. Therefore, based on the current evidence from randomised trials, extending mammography screening to younger age groups cannot be recommended.

Gut Microbiome and Cancer Therapy

Gut Microbes May Help in Cancer Treatment

By Ramadhani Chambuso

Since the gut is the largest immunological organ in the body, research has found that certain anticancer drugs work better with prior or concomitant modulation of specific gut microbiome to optimize maximum therapeutic outcome in the treatment of skin and lung cancer in mice. However, this strong interrelationship between the immune system and the host gut microbiota which can determine responses to cancer therapies has not yet been demonstrated in humans, although efforts are made to have ethical clearance to conduct further clinical trials.

Welcoming New Members

Postgraduate Cancer Research Initiative (CRI) Opens Door to New Postgraduates!

On behalf of Prof. Jennifer Moodley, we would like to extend a cheerful welcome to the new members who have joined the Postgraduate Cancer Research Initiative (CRI). As you are aware, this group was founded in 2015 as “Cancer PhD Mentorship Group” and was only for PhD students. This year, after much discussion, we extended the invitation and membership to MSc students doing cancer-related projects; hence, the name “Postgraduate Cancer Research Initiative”. Therefore, we are delighted to have all the new postgraduate members from different divisions and departments join our group.

Our main goal is to offer mentorship to postgraduate students, identifying and assisting them in their areas of need in academics and research. It also provides students with the opportunity to share exciting ideas in cancer research. This is not limited to policy implementation, translational research, and any opportunities in the discipline.

Thanks to all the old and new members who made a huge effort to participate in our first two meetings (7th and 27th July 2017 chaired by Prof. Jennifer Moodley and Dr. Ramadhani Chambuso, respectively). To those that were unable to attend, it is our pleasure to welcome you!

Cancer policies and key role players in cancer research

Cancer policies and key role players in cancer research

2img-20160907-wa0001img-20160907-wa0002The Cancer Research Initiative hosted a seminar for the members of the PhD mentorship group to provide an overview of cancer policies, key organisations and role players in cancer research.

Dr Henry Adeola began his presentation by discussing the urgent need for cancer control policies in Africa. The burden of cancer on the continent is set to exponentially increasing due to industrialisation and the ageing population and cancer control needs to be prioritised according to the World Health Organisation (WHO). In South Africa, only two policies including the HPV vaccination in school girls and the Tobacco Products Control Act in 1993 have been approved and implemented by the government. A draft National Cancer control and prevention document has been developed and is currently undergoing revisions. However, the anticipated date of the final policy is yet to be released. It is clear that the first steps towards a comprehensive cancer control policy have been put into place but more needs to be done to hasten the implementation of an integrated and practical cancer control policy.

Vedantha Singh provided an outline of the key role players in cancer research and how students can make use of the available resources to supplement their own research. International organisations such as the WHO’s International Agency for Cancer Research (IARC) and their cancer surveillance data website, GLOBOCAN provide important epidemiological and population based statistics on the global burden of cancer. Role players in cancer research within Africa including the African Organisation for Research and Training in Cancer (AORTIC) and the African Cancer Registry Network (AFCRN). South African role players in cancer research including the policy makers (Department of Health), advocacy groups/NGOs, academic/research institutions and cancer registries were then described. The key message was that each of the role players needs to be engaged in integrative, collaborative efforts to control, prevent and overcome cancer.

Colleen Marco (CANSA) concluded the seminar by emphasising that cancer control and prevention efforts need to be practical and implementable in the South African setting. The major problem is lack of urgency to act and limited political will. The topic of cancer is still taboo in our communities and this needs to be addressed (perhaps through research) in order to ensure that cancer prevention is taken seriously.

Discussion

Students in attendance engaged in a discussion surrounding the importance of policies to be developed using evidence based research. The need to engage all stakeholders throughout the research process was also discussed. The general consensus of the group was to drive political will and change through research that is derived from integrated and translatable research questions.

Please share your opinion on how we can drive cancer control in South Africa?

16th IUBMB Young Scientist Program and Conference (14-21 July 2016, Vancouver, Canada)

16th IUBMB Young Scientist Program and Conference (14-21 July 2016, Vancouver, Canada)

By Tamara Stelma (STLTAM001@myuct.ac.za)

T Stelma 5The International Union of Biochemistry and Molecular Biology (IUBMB) Young Scientist Program gave 42 PhD students or T Stelma 6postdoctoral fellows the opportunity to travel to Vancouver, Canada, and attend an inspiring academic program at the University of British Columbia. I was privileged to be a part of the young scientist group that T Stelma 1represented 26 different countries around the world. We each got the opportunity to do an oral presentation on our research as well as a poster presentation which facilitated useful and interesting T Stelma 4discussions around our work. We were also taken on a tour of the Michael Smith Genome Science Centre where we got to experience
the workings of the world’s first Personalised Oncogenomics Project (POG project). The program provided a great opportunity for young scientists to network with each other as well as leading researchers in their respective fields.

The international conference on biochemistry and molecular biology followed the young scientist program and was held at Vancouver’s East Convention Centre. The conference brought delegates together from all corners of the globe to discuss signaling pathways in development, disease and aging. Exceptional science was presented by leading researchers in their fields including two Nobel and 5 Gairdner prize winners. The plenary sessions covered a diverse range of topics including; cell death and aging, cancer causes and progression, circadian rhythms, regulation of RNA and proteins as well as membrane proteins and channels.

The next IUBMB conference will be held in Seoul, South Korea, 4-8 June 2018. I recommend all future PhD students and Postdoctoral Fellows to apply for the Young Scientist program as it is an opportunity not to be missed.
