A Molecular Mechanism Of Epithelial To Mesenchymal Transition (Emt): An Evidence Based Lesson Applying Molecular Biology Through The Lens Of Cancer, Sophie Hasson, Melissa Rowland-Goldsmith
A Molecular Mechanism Of Epithelial To Mesenchymal Transition (Emt): An Evidence Based Lesson Applying Molecular Biology Through The Lens Of Cancer, Sophie Hasson, Melissa Rowland-Goldsmith
Open Educational Resources
This lesson aims to strengthen students’ critical thinking and molecular biology data analysis skills as well as their understanding of concepts related to the hallmark of cancer: tissue invasion and metastasis. Students begin by learning about the invasion of cancer cells, Epithelial-Mesenchymal Transition (EMT), and an important protein involved in EMT: E-cadherin. They then apply molecular biology knowledge to analyze data from multiple papers to infer the relationship between Snail and E-cadherin in different types of cancers. Next, they continue to interpret data from many papers to determine that a repressor transcription factor is present during EMT in cancer cells …

Kinetic Model Of Glycolysis And Glutaminolysis Interplay Developed In Matlab Simbiology, Zohreh Mirveis, Hugh J. Byrne, Nitin Patil
Datasets
This dataset contains a kinetic model developed in MATLAB SimBiology to simulate the metabolic dynamics of glycolysis and glutaminolysis and their interconnection. The model was used in the study ‘Experimental and computational investigation of the kinetic evolution of the glutaminolysis pathway and its interplay with the glycolysis pathway’ (Mirveis et al., 2024). The dataset includes the original SimBiology project file together with the experimental data used for model training. These resources enable reproduction of the simulations reported in the publication and provide a reusable framework for further computational exploration of metabolic pathway kinetics.
Roles Of Mitochondrial Chchd2 And Gpcr-Associated Β-Arrestin2 In The Pathogenesis Of Lewy Body Disorders, Teresa R. Kee
Roles Of Mitochondrial Chchd2 And Gpcr-Associated Β-Arrestin2 In The Pathogenesis Of Lewy Body Disorders, Teresa R. Kee
USF Tampa Graduate Theses and Dissertations
Coiled-coil-helix-coiled-coil-helix domain containing 2 (CHCHD2) is a mitochondrial protein that plays important roles in cristae structure, oxidative phosphorylation, and apoptosis. Multiple mutations in CHCHD2 have been associated with Lewy body disorders (LBDs), such as Parkinson’s disease (PD) and dementia with Lewy bodies (DLB), with the CHCHD2T61I mutation being the most widely studied. We generated the first transgenic mouse models expressing human CHCHD2WT and the PD-linked CHCHD2T61I mutation driven by the mPrP promoter. CHCHD2T61I Tg, but not CHCHD2WT Tg mice exhibit perinuclear mitochondrial aggregates, neuroinflammation, and have impaired long-term synaptic plasticity associated with synaptic dysfunction. Dopaminergic neurodegeneration, a hallmark of PD, …
Macrophage-Driven Car T Cell Resistance In B Cell Lymphoma, Sae Bom Lee
Macrophage-Driven Car T Cell Resistance In B Cell Lymphoma, Sae Bom Lee
USF Tampa Graduate Theses and Dissertations
Chimeric antigen receptor (CAR) T-cell therapy has revolutionized the treatment of patients with relapsed/ refractory large B cell lymphoma (LBCL). Despite its promising efficacy, a subset of patients experiences primary resistance or relapse. In Chapter 2, we explore the tumor microenvironment (TME)-induced resistance mechanisms in patients with LBCL. Analysis of the intratumoral immune infiltrates in pre-infusion tumor biopsies revealed that the levels of immunoregulatory macrophages were elevated in patients who responded poorly to axicabtagene ciloleucel (axi-cel). Using preclinical mouse B cell tumor models, we found that the CAR T-cell-produced interferon-gamma (IFN-γ) enhanced the expression of inducible nitric oxide synthase (iNOS, …
Ring Domain, David J. Hall
Ring Domain, David J. Hall
Protein Domains
Ring domain #1CHC. The RING finger is a specialized type of Zn finger consisting of 40–60 residues that binds two atoms of zinc, and is involved in mediating protein—protein interactions. Many zinc fingers bind nucleic acids. The presence of a RING finger domain is a characteristic of RING-class E3 ubiquitin protein ligases capable of transferring ubiquitin from an E2 enzyme to a substrate protein.
Sh2 Domain, David J. Hall
Sh2 Domain, David J. Hall
Protein Domains
SH2 domain #1BFJ. Src-homology 2 (SH2) domains are modules of ~100 amino acids that bind to specific phospho tyrosine (pY) containing peptide motifs. Conventional SH2 domains have a conserved pocket that recognizes pY, and a more variable pocket that binds 3-6 residues C-terminal to the pY and confers specificity.
Sh3 Domain, David J. Hall
Sh3 Domain, David J. Hall
Protein Domains
SH3 domain #1NEB. Src-homology 3 (SH3) domains bind to Pro-rich peptides that form a left-handed poly-Pro type II helix, with the minimal consensus Pro-X-X-Pro. Each Pro is usually preceeded by an aliphatic residue. Each in the aliphatic-Pro pair binds to a hydrophobic pocket on the SH3 domain.
Ig Domain, David J. Hall
Ig Domain, David J. Hall
Protein Domains
Ig domain #2CKN. This particular domain is named for the first protein in which it was found, the immunoglobulin. An immunoglobulin is a antibody. Antibodies are generated by our immune system to recognize the specific size, shape and charge of pathogens. This domain is also found on the extracellular portion of many receptors including the interleukin-1 family of receptors.
Beta Barrel, David J. Hall
Beta Barrel, David J. Hall
Protein Domains
Beta barrel (cyan fluorescent protein) #4AR7. This fluorescent protein is a variation of green fluorescent protein from a jellyfish and is the only domain that is a complete protein. The protein is routinely used to visualize a variety of biological processes. The beta barrel domain is a beta sheet wrapped around the fluorescent active site to provide structure.
Helix Turn Helix Domain, David J. Hall
Helix Turn Helix Domain, David J. Hall
Protein Domains
Helix turn helix domain #3V1A. The helix-turn helix is a DNA-binding domain. The two alpha helices are the reading or recognition helices, which bind in a groove in the DNA and recognize specific gene regulatory sequences in the DNA.

Phi X 174, David J. Hall
Infectious Pathogens
Phi X 174 database number # 1CD3. Phi X 174 is a virus that infects bacteria and was the first DNA-based genome to be sequenced in 1977. This bacteriophage has a [+] circular single-stranded DNA genome. The assembly of the capsid has been successfully done in vitro and is the focus of many studies on self-assembly, drug delivery and nanotechnology.
Dengue Virus, David J. Hall
Dengue Virus, David J. Hall
Infectious Pathogens
Dengue virus, database # 1THD Dengue fever, is an infectious tropical disease caused by the dengue virus and transmitted by mosquito. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever. Dengue is a positive strand RNA virus that is part of the flavivirus family. Dengue is an enveloped virus meaning it has a nucleocapsid protecting the RNA and the nucleocapsid is surrounded by lipids (hence the name enveloped).

Infectious Pathogens
Human Papilloma virus 16, database# 1DZL Infection by most papillomaviruses is either asymptomatic or causes small benign tumors, known as papillomas or warts (e.g. human papillomavirus HPV6 or HPV11). Papillomas caused by some types, however, such as human papillomaviruses 16 and 18, carry a risk of becoming cancerous. Human papilloma virus is a non-enveloped, double stranded, circular DNA virus.

Crystallization is the most serious bottleneck in high-throughput protein-structure determination by diffraction methods. We have used data mining of the large-scale experimental results of the Northeast Structural Genomics Consortium and experimental folding studies to characterize the biophysical properties that control protein crystallization. This analysis leads to the conclusion that crystallization propensity depends primarily on the prevalence of well-ordered surface epitopes capable of mediating interprotein interactions and is not strongly influenced by overall thermodynamic stability. We identify specific sequence features that correlate with crystallization propensity and that can be used to estimate the crystallization probability of a given construct. Analyses of …
