The landscape of viral strains and lineages of SARS-CoV-2 keeps changing and is currently dominated by Delta and Omicron variants. Members of the latest Omicron variants, including BA.1, are showing a high level of immune evasion, and Omicron has become a prominent variant circulating globally. In our search for versatile medicinal chemistry scaffolds, we prepared a library of substituted α-aminocyclobutanones from an α-aminocyclobutanone synthon (11). We performed an in silico screen of this actual chemical library as well as other virtual 2-aminocyclobutanone analogs against seven SARS-CoV-2 nonstructural proteins to identify potential drug leads against SARS-CoV-2, and more broadly against coronavirus …
Role Of Micrornas In Intestinal Inflammation And Barrier Homeostasis After Alcohol And Burn Injury, Caroline J. Herrnreiter
Role Of Micrornas In Intestinal Inflammation And Barrier Homeostasis After Alcohol And Burn Injury, Caroline J. Herrnreiter
Dissertations
MicroRNAs are small noncoding RNA molecules that negatively regulate gene expression. Within the intestinal epithelium, miRNAs play a critical role in gut homeostasis and aberrant miRNA expression has been implicated in various disorders associated with intestinal inflammation and barrier disruption. In this study, we sought to profile changes in intestinal epithelial cell miRNA expression after alcohol and burn injury and elucidate their impact on inflammation and barrier integrity. In a more targeted approach, we began by focusing on anti-inflammatory miRNAs that, when downregulated, could exacerbate inflammation and result in intestinal barrier disruption. Using a mouse model of acute ethanol intoxication …

Characterizing The Dynamic Localization Of Cmi In Early Drosophila Development, Asra Habibullah
Master's Theses
The COMPASS-like family of lysine methyltransferases, MLR/MLX complexes, are epigenetic regulators that are essential for normal development through the methylation of the fourth lysine residue on histone 3 (H3K4), a universal epigenetic mark associated with active transcription. This family of complexes is highly conserved from yeast to mammals and the genes encoding the human MLR complexes have been associated with various developmental diseases and cancers (Dingwall and Fagan, 2019). In D. melanogaster, the enzymatic methyltransferase core of this complex is composed of two proteins: Cara Mitad (Cmi, also known as Lpt) and Trithorax-related (Trr). Although these proteins have been shown …

Bcl2-associated athanogene-3 (BAG3) is a pro-autophagy co-chaperone that we havepreviously shown localizes to the cardiac sarcomere and is critical for proteostasis and maintenance of normal sarcomeric function. Indeed, BAG3 loss in heart failure (HF) results in accumulation of ubiquitinated sarcomeric proteins, and depressed maximum force generating capacity (Fmax). However, how BAG3 is regulated in the cell is not well understood, with uncertainty about its structure and proteoforms. During our analysis of human heart tissue, BAG3 appears as a “doublet”, with one band at 74 kDa (BAG3-Z) and a second at a higher 85 kDa (BAG3-FL). Previous studies hypothesized the full-length …
Dynamic Control Of The Cardiac Calcium Pump, Sean Robert Cleary
Dynamic Control Of The Cardiac Calcium Pump, Sean Robert Cleary

The sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) sequesters Ca2+ into the endoplasmic reticulum of cells to establish a reservoir for Ca2+ signaling. In the heart, the activity of this transporter is tightly controlled via direct interactions with two competing regulatory micropeptides: phospholamban (PLB) and dwarf open reading frame (DWORF). PLB inhibits SERCA, while DWORF activates SERCA. These competing interactions determine cardiac performance by modulating the Ca2+ signals that drive the contraction/relaxation cycle. Previous studies indicated these SERCA-micropeptide interactions are Ca2+-sensitive; SERCA binds PLB more avidly at low cytoplasmic [Ca2+] but binds DWORF better when [Ca2+] is high. Here, FRET-microscopy demonstrated that this …
