Our project aims to explore the functional significance of non-synonymous single nucleotide polymorphisms (nsSNPs) within the CAPN10 gene, an important exploration of the complex genetic landscape of type 2 diabetes mellitus (T2DM) susceptibility. By employing a range of bioinformatics tools, we identified 15 nsSNPs likely to exert deleterious effects, with 5 certain amino acid substitutions showing particular promise due to their presence in highly conserved regions and impact on protein stability. This study provides valuable insights into CAPN10 variants, a significant step towards understanding the complex interactions between genetic variation and illness risk. This study therefore facilitates future large-scale population studies and personalized medicine approaches, and potentially informs novel drug discovery efforts.

Martha Luka, Ruth Nanjala, Wafaa Rashed and Winfred Gatua
Rhinoviruses (RV), common respiratory pathogens, are positive-sense, single-stranded RNA viruses characterized by a high antigenic diversity and mutation rate. With their genome approximately 7.2 kb in length, RVs exhibit mutation rates between 10^-3 and 10^-5 mutations per nucleotide per replication event. These viruses are classified into 169 types across three species: RV-A, RV-B, and RV-C. Genotype assignment, a critical aspect of RV research, is based on pairwise genetic distances and phylogenetic clustering with prototype strains, a process currently executed through multiple steps, making it laborious. In this study, we developed an R package to streamline RV genotype assignment, thereby facilitating genomic scientists in efficiently genotyping RV infections.

Type 2 Diabetes Mellitus (T2DM) still poses a significant healthcare challenge within the African continent and the world at large. This menace has been primarily attributed to macrovascular and microvascular complications arising from hyperglycemia. While glycemic control remains paramount, adjunctive therapeutic strategies targeting specific pathways implicated in diabetic complications offer promising avenues for improving associated morbidity.
Our research focuses on the aldose reductase (AR) enzyme, a key enzyme in glucose metabolism whose activity and metabolites under high glucose conditions trigger different pathways resulting in diabetic complications. Unfortunately, existing AR-targeting drugs come with limitations such as toxicity, adverse reactions, and a lack of specificity. In this study, we explored the potential of indigenous African compounds, as inhibitors of AR for effective pharmacological intervention.
To achieve this, we employed computational techniques like molecular docking and molecular dynamics simulations where we scrutinized natural compounds sourced from databases for their inhibitory efficacy against AR. The drug-likeness and ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) properties of successfully screened lead compounds were selected. Molecular dynamics stimulations determined the free binding energy of the protein-ligand complexes using molecular mechanics with generalized born and surface area (MMGBSA) solvation.
This study serves as a crucial step toward identifying novel and alternative compounds for inhibiting AR, ultimately paving the way for more effective treatments for type 2 diabetes mellitus and its associated complications.

Epilepsy is a chronic neurological disorder characterized by recurring spontaneous seizures. It is one of the most common and most disabling chronic neurological disorders affecting more than seventy million individuals worldwide. More than 20 antiseizure drugs are available for the symptomatic treatment of epileptic seizures, but drug resistance appears in around 30% of patients, leading to unsuccessful treatments. Despite various research efforts, the exact mechanisms underlying drug resistance are not fully understood. Unraveling the genomic landscape of anti-epileptic drug resistance represents a pioneering endeavor in the field of epilepsy treatment. In this study, we employed advanced bioinformatics methods to delve into the intricate genetic makeup of individuals with epilepsy to decipher the underlying mechanisms driving resistance to anti-epileptic drugs (AEDs). By analyzing vast genomic datasets, including bulk RNA sequences, we identified key genetic variants, gene expression patterns, and molecular pathways associated with AED resistance. This comprehensive approach not only enhances our understanding of the complex interplay between genetics and drug response but also holds promise for the development of personalized therapeutic strategies tailored to individuals living with epilepsy.

Drug Candidate Development against Non-alcoholic Steatohepatitis (NASH)
Chimenya Ntweya, Desmond Osarfo Amoah and Diabate Oudou
Nonalcoholic fatty liver disease (NAFLD) is characterized by the abnormal accumulation of fat in the liver (hepatic steatosis) in the absence of other causes of secondary liver fat accumulation. NAFLD encompasses both nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH), which is diagnosed when there is evidence of inflammatory activity and hepatocyte injury in steatotic liver tissue. NASH represents the most severe form of NAFLD, wherein excessive fat deposits accumulate in the liver. Unlike NAFL, NASH carries the highest risk of progressing to cirrhosis, liver failure, and liver cancer. The global
prevalence of NASH exceeds 115 million adults, a number projected to rise by 2030, imposing substantial burdens on individuals, families, and economies. Currently, there are no approved medications specifically for treating NASH. Therefore, this project aims to identify potential therapies for NASH using computational methods. In this study, we utilized a series
of in-silico techniques such as homology modeling, ligand-based pharmacophore modeling, molecular docking, and molecular dynamic simulations to identify potential drug candidates for treating NASH. Our research makes a major contribution to the ongoing effort to develop drugs for NASH.

George Eusebio Kuodza, Ifeoluwa Hephzibah Ojelabi and Jonathan Kalami
Epilepsy, is one of the most prevalent neurological conditions, which presents as a complex disorder, characterized by recurrent seizures with excessive and abnormal neuronal discharges, it has been attributed to both genetic and environmental factors. Gene regulation of epigenetics basically includes DNA methylation, histone modification and RNA methylation, so as to change the genetic information of organisms without altering the sequence of DNA nucleotides. Our focus in this study is on the DNA methylation so as to give plausible answers for frequent characteristics of complicated disorders. We identified the methylated regions in patients with epilepsy using Bisulfite mapping and methylation calling, comparing differences in methylation among those that have temporal lobe epilepsy with hippocampal sclerosis and those with temporal lobe epilepsy without hippocampal sclerosis. Our study’s result will give insight into the different effects of DNA methylation in epilepsy and possibly the molecular mechanisms underlying the complications. With this understanding, personalized treatments may be developed.

Mamadou D. Coulibaly, Ndong H. Ndang, Oyepeju D. Atarase, Fousseyni Kane, Adham Hallal and Abdulwasiu Tiamiyu
Malaria susceptibility is the predisposition to be infected by malaria parasites. Factors influencing susceptibility to malaria parasites could be genetic or generic such as age, sex composition, social and economic status as well as mobility of the population. These factors create a difference in susceptibility rates among populations. Unfortunately, certain populations become more susceptible to malaria infection than others. It is therefore key to understanding in detail populations more susceptible to infections first to inform policy and then implement cost-effective interventions with priority given to populations with higher susceptibility to malaria. In this project, we analyzed and modeled genomic data consisting of biological susceptibility factors such as age and sex using machine learning to predict malaria susceptibility in diverse African populations.

Ojochenemi A. Enejoh, Chinelo Henrietta Okonkwo, Moses Ainembabazi, Hector Nortey, Oluwasegun Adesina Babaleye and David Olatunji
TGR5 agonists have emerged as a promising class of therapeutic agents for the treatment of type 2 diabetes mellitus. Machine learning algorithms combined with molecular docking and simulation techniques provide valuable insights into the interactions between small molecules and TGR5 receptors. This approach not only helps in predicting the potential efficacy of a molecule, but also aids in understanding the molecular mechanisms underlying TGR5 activation.
In this study, to identify novel TGR5 agonists, we employed a machine learning-based modeling approach which involved the development and validation of machine learning-based models to predict the binding affinity of small molecules to TGR5, followed by molecular docking and simulation techniques. This allowed for the virtual screening of a large compound library to identify potential small molecule candidates that can bind to and activate the TGR5 receptor. Moreover, TGR5 agonists have been shown to stimulate GLP-1 secretion, which can lead to improved glycemic control through glucose-dependent insulin secretion. These advancements in the field of diabetes treatment have the potential to significantly improve diabetes management and treatment outcomes.

Longitudinal aerosol metagenomic profiling will eventually change our understanding on biotic exposures. That is, with wearable devices we can collect longitudinal cumulative aerosol exposure samples from our daily environment. It may even be possible to accurately predict changes in an individual’s health using personalized aerosol metagenomic profiling.
In this project, we assessed the reproducibility of fine-scale metagenomic profiling of microbes (ie. bacteria, virus and fungi) from personalized longitudinal aerosol samples. In particular, we evaluated the diversity and distribution of likely pathogenic microbes present in the personal aerosol profiles. For the project, we have six months bi-weekly personal-aerosol sampled metagenome data available from fifteen individuals. From these previously published aerosol metagenomes, we assessed the fine-scale longitudinal biotic profiles. Our results indicate that the microbial species detected from the personal aerosol sampled metagenomes are highly reproducible and enable longitudinal profiling of likely pathogenic exposures at individual level.
