Rational Design Of Small Molecule Disruptors Of Protein-Protein Interactions: Pd-1/Pd-L1; C-Myc, Arid4b, Samuel Ofori Jan 2021

Rational Design Of Small Molecule Disruptors Of Protein-Protein Interactions: Pd-1/Pd-L1; C-Myc, Arid4b, Samuel Ofori

Theses and Dissertations--Chemistry

Protein-protein interactions (PPIs) are vital to many biological processes, including gene expression, and immune reactions to pathogens. There are approximately 650,000 PPIs in humans with pertinent physiological functions. Aberrant expression of PPIs lead to improper function and contribute to a plethora of disease conditions including cancer. Thus, PPIs represent an enormous target space for drug discovery and chemical probes. Direct targeting of clinically relevant PPIs with small molecules remains an unmet medical need. Development of small-molecule inhibitors of PPIs is a challenging enterprise and in most cases considered undruggable due to large protein surfaces, lack of deep binding pockets and …

Theses and Dissertations--Chemistry

Cancer is a worldwide public health crisis that requires new and improved drugs to be developed to extend survival rates and improve quality of life for the patient. Platinum-based drugs are used in approximately 50% of cancer treatment regimens. These drugs are highly effective in many kinds of cancer; however, cancers can develop platinum resistance and these drugs have troubling side effects that reduced their use and efficacy. To overcome these disadvantages, many other metals have been studied for their anticancer properties. Notably, the anticancer properties of ruthenium-based agents have drawn considerable attention with multiple ruthenium complexes entering clinical trials. …


Investigation Into The Structure And Function Of Streptococcal Antigen I/Ii Family Of Proteins, Joshua L. Mieher Jan 2021

Investigation Into The Structure And Function Of Streptococcal Antigen I/Ii Family Of Proteins, Joshua L. Mieher

All ETDs from UAB

Streptococci are involved in the infections of the oral cavity as well as at various sites throughout the body. Their initial contact with tissues/surfaces is enabled by adhesins present on the microbial surface. Among these the Antigen I/II- family (AgI/II) of adhesins are known be important factors in these infections as they enable adherence to multiple host proteins thus allowing the bacteria to gain a foot hold. In this thesis, we have structurally and functionally characterized yet another adhesin on S. mutans, the glucan binding protein C, which resembles the V-region of AgI/II. In addition, we have also resolved the …

Patients with long-term estrogen-deprived breast cancer (BC), after resistance to tamoxifen or aromatase inhibitors develops, can experience tumor regression when treated with estrogens. Estrogen’s anti-tumor effect is attributed to apoptosis via the estrogen receptor (ER). Estrogen treatment can have unpleasant gynecological and non-gynecological adverse events thus the development of safer estrogenic agents remains a clinical priority. Here, we study synthetic selective estrogen mimics (SEMs) BMI-135 and TTC-352, and the naturally-occurring estrogen estetrol (E4), which are proposed as safer estrogenic agents compared to 17β-estradiol (E2), for the treatment of endocrine-resistant BC. TTC-352 and E4 are being evaluated in BC clinical trials. …

Exploring The Dopamine Transporter Utilizing A Two-Pronged Approach With Novel Cathinone Analogs And Mutant Dopamine Transporters, Charles B. Jones Iii

Theses and Dissertations

The dopamine transporter (DAT) is responsible for the removal of the neurotransmitter from the synaptic gap and a therapeutic target for a multitude of drugs. While the ortholog Drosophila melanogaster dopamine transporter (dDAT) and human serotonin transporter (hSERT) have resolved structures, the human dopamine transporter (hDAT) does not. A 3-D computational homology model of hDAT was constructed for the study of molecular interactions with agents within the central binding site (S1) of the transporter.

Synthetic cathiones are a class of abused stimulant drugs that primarily target DAT. Greater than 150 cathinones have been identified on the clandestine market but there …

Assessing The Comfort Level Of Speech-Language Pathologists In Assessing And Treating Deaf And Hard Of Hearing Children, Kaitlyn Burkamper

Honors Program Theses

When a child is diagnosed with a hearing loss, there are many different facets of their diagnosis to consider, and all of these facets are affected by the configuration, type, and severity of the hearing loss. Because of the patient's age, all decisions are at least impacted, if not made, by their parents or guardians. Depending on these factors, there are options for assistive devices, such as hearing aids, and one of the main concerns is access to language. While signed language is a completely valid path for a child with hearing loss, some parents make the decision that their …

Chromosome translocations involving mixed lineage leukemia (MLL) gene cause acute leukemia with a poor prognosis. MLL is frequently fused with transcription cofactors AF4 (~35%), AF9 (25%) or its paralog ENL (10%). The AHD domain of AF9/ENL binds to AF4, its paralog AFF4, or histone-H3 lysine-79 (H3K79) methyltransferase DOT1L. Formation of AF9/ENL/AF4/AFF4-containing super elongation complexes (SEC) and the catalytic activity of DOT1L are essential for MLL-rearranged leukemia. Protein-protein interactions (PPI) between AF9/ENL and DOT1L/AF4/AFF4 are therefore a potential drug target.

Methods: Compound screening followed by medicinal chemistry was used to find inhibitors of such PPIs, which were examined for their biological …

Novel Heat Index Models For Subtropical Region Based On Daily Milk Production Incrossbred Holstein Cows, Neeraj Kashyap, Atish Kumar Chakravarty, Bharti Deshmukh Jan 2021

Novel Heat Index Models For Subtropical Region Based On Daily Milk Production Incrossbred Holstein Cows, Neeraj Kashyap, Atish Kumar Chakravarty, Bharti Deshmukh

Turkish Journal of Veterinary & Animal Sciences

The quantification of the effect of heat stress imposed due to higher rate of heat gain on animal production is a prerequisite while estimating effects of heat stress. Temperature humidity index (THI) models developed empirically using meteorological parameters have been utilized as an indicator of heat stress. This study attempted to develop a heat index model with respect to productivity of the crossbred Holstein cows. More than 1.23 million daily milk yield records of 1860 crossbred cattle spread over a duration of 30 years were utilized. Statistically significant (p < 0.0001) partial regression coefficients were estimated as 0.0748 ± 0.0009 for dry bulb temperature (T$_{db}$) and -0.2228 ± 0.0011 for wet bulb temperature in model 1, -0.0182 ± 0.0005 T$_{db}$ and -0.1205 ± 0.0006 for vapour pressure in model 2, -0.0150 ± 0.0006 for Tdb and -0.1151 ± 0.0006 for dew point temperature in model 3 while as -0.1283 ± 0.0004 for T$_{db}$ and -0.0394 ± 0.0002 for relative humidity in model 4. The ratio of the partial regression coefficients of meteorological parameters (ß2/ß1) was -2.9791 in model 1, 6.8739 in model 2, 7.6731 in model 3 and 0.3073 in model 4. The developed THI models are based on the effect of meteorological parameters on daily productivity of the dairy animals, so the weightages to meteorological parameters were contrastingly different than the reported THI models. These models may successfully be used to evaluate the impact of heat stress on crossbred Holstein cows with respect to milk productivity and many other traits.

Oxygen regulation and homeostasis are vital for proper function in healthy cells, as are core components of aerobic metabolism and efficient ATP generation to supply our energy needs. Maintaining pH homeostasis is also of primary importance; cells maintain pH homeostasis through a host of active and passive transporters to maintain pH balance both inside and outside of the cell.

Events of uncontrolled cellular proliferation, also known as cancer, survive and thrive under conditions that perturb the delicate balance …
