Renal medullary carcinoma (RMC) and fumarate hydratase (FH)-deficient renal cell carcinoma (RCC) are rare and highly aggressive cancers. Although the combination of vascular endothelial growth factor (VEGF) inhibition by bevacizumab and epidermal growth factor receptor (EGFR) inhibition by erlotinib is clinically used for both diseases, the differential effect of each component has not been investigated. Transcriptomic profiling revealed that RMC and FH-deficient tumor tissues demonstrate increased EGFR but not VEGF expression compared with adjacent normal kidney. Subsequent in vitro studies revealed that RMC and FH-deficient cell lines are sensitive to erlotinib treatment, whereas clear cell RCC cell lines are resistant. …

Cat: A Conditional Association Test For Microbiome Data Using A Permutation Approach, Yushu Shi, Liangliang Zhang, Kim-Anh Do, Robert R Jenq, Christine B Peterson

Faculty, Staff and Student Publications

In microbiome analysis, researchers often seek to identify taxonomic features associated with an outcome of interest. However, microbiome features are intercorrelated and linked by phylogenetic relationships, making it challenging to assess the association between an individual feature and an outcome. This paper proposes a novel conditional association test, CAT, that can account for other features and phylogenetic relatedness when testing the association between a feature and an outcome. CAT adopts a permutation approach, measuring the importance of a feature in predicting the outcome by permuting operational taxonomic unit/amplicon sequence variant counts belonging to that feature from the data and quantifying …

Pol Θ-Mediated End-Joining Uses Microhomologies Containing Mismatches, Yuzhen Li, Ngoc K Dang, Wei He, Mark Returan, Denisse Carvajal-Maldonado, Han Xu, Richard D Wood

Faculty, Staff and Student Publications

DNA polymerase theta (Pol θ) initiates repair of DNA double-strand breaks by pairing single strands at short "microhomologies". It is important to understand microhomology selection, as some cancer cells rely on Pol θ for survival. Here, we investigate end-joining by purified human Pol θ, employing DNA sequencing of products generated from oligonucleotide libraries having diverse 3' ends. Pol θ overwhelmingly selects short internal microhomologies found within 15 nucleotides of the terminus of single-stranded DNAs, restricting deletion size during end-joining. Significantly, we find that the selected microhomologies are usually interrupted by mismatches and that base pairing within 6 nucleotides of the …

Commentary On Blaser's "Antibiotic Use And Its Consequences For The Normal Microbiome", Fred C. Tenover

AMR Commentary

If you have not read this eye-opening commentary by Dr. Martin Blaser about the negative impact of the widespread use of antibiotics in children, you should. The goal of giving antibiotics to children usually is to treat an infection — an earache, a respiratory tract infection, or perhaps a potentially deadly bloodstream infection. Those antibiotics, however, will often kill more than just the bacteria that are causing the infection. Humans have large quantities of “good bacteria” in our intestinal tracts, on our skin, and elsewhere on our body that play an important role in keeping us healthy.

Tissue Engineering: History, Principles, Applications, Challenges, And Future Work, Alexa Cesari, Ms

Student Papers, Posters & Projects

Tissue engineering is a comprehensive and cutting-edge field that leverages principles from multiple scientific disciplines to assist in regenerative medicine. It is defined by the most basic structure of the human body, the cell. When an injury occurs, cells send signals to initiate wound healing processes. In most cases, the body is equipped to heal wounds on its own; however, there are instances where wounds are too severe and cannot undergo proper regeneration. When this occurs, alternative measures are taken to assist in wound repair. With numerous advancements made over the years, tissue engineering has become an increasingly common method …

Economic Evaluation Of Caregiver Interventions For Children With Developmental Disabilities: A Scoping Review, Angela Kairu, Edwin Dzoro, Vibian Angweny, Charles Newton, Charlotte Hanlon, Rosa Hoekstra, Amina Abubakar, Edwine Barasa

Institute for Human Development, East Africa

Globally, families with children with developmental disabilities (DDs) experience challenges, including social isolation, stigma, and poverty, especially in low-income settings in Africa. Most children with DDs in Africa remain unidentified and receive no formal support. Caregiver interventions focusing on education and training for the carers/parents have been shown to be adaptable and low intensity in implementation, although the economic evidence is limited. This review aimed to describe the evidence and methodological aspects of economic evaluations for caregiver interventions for DDs. The Arksey and O’Malley framework was applied. Seven electronic databases, grey literature and cited references were systematically searched to identify …

Faculty/Staff Personal Papers

Best known for his natural history studies on evolution and biogeography, Alfred Russel Wallace (1823−1913) had a significant second career as a social critic. One of his most controversial stances was his position on (smallpox) vaccination. Anti-vaxxers of the present frequently bring up his name as a resource for their side, but the situation is not so easily reducible to that.

Vitamin D Status And Risk For Breast Cancer In Kenya, Ronald Wasike, Victor Mobegi, Esther Maina, Francis Makokha, Robert Armstrong, Annastacia Mbithi

General Surgery, East Africa

Background: Vitamin D plays a critical role in bone metabolism, calcium regulation, and various cellular processes, including those linked to cancer. The biologically active form, 1,25-dihydroxyvitamin D [1,25(OH)2D], works through the Vitamin D Receptor (VDR). Polymorphisms in VDR and related genes have been associated with cancer risk, including breast cancer. This case-control study aimed to investigate the relationship between serum vitamin D levels and breast cancer among Kenyan women.

Methods: Serum 25-hydroxyvitamin D [25(OH)D] levels were measured in 112 breast cancer patients and 106 controls using electrochemiluminescence.

Paediatrics and Child Health, East Africa

Background: Severe pneumonia remains the leading cause of morbidity and mortality among children worldwide. Severe pneumonia causes death during hospitalization, and survivors are prone to malnutrition after discharge from the hospital. The World Health Organization and United Nations International Children’s Fund recommend ‘continued’ feeding following a severe pneumonia illness without specific recommendations on nutritional support. This recommendation could influence health workers’ and caregivers’ nutritional practices. This study aimed to explore the perspectives and practices of health workers and caregivers for mitigating malnutrition among children with severe pneumonia.

Methods: We conducted a cross-sectional qualitative study between June and November 2021 among …

Recent studies have highlighted the importance of mitochondria in NP cells and articular chondrocyte health. Since the understanding of mechanisms governing mitochondrial dynamics in these tissues is lacking, we investigated the role of OPA1, a mitochondrial fusion protein, in their homeostasis. OPA1 knockdown in NP cells altered mitochondrial size and cristae shape and increased the oxygen consumption rate. OPA1 governed the morphology of multiple organelles, including peroxisomes, early endosomes and cis-Golgi and loss resulted in the dysregulation of autophagy. Metabolic profiling and
