The Constitutively Active Form Of A Key Cholesterol Synthesis Enzyme Is Lipid Droplet-Localized And Upregulated In Endometrial Cancer Tissues, Hudson W Coates, Tina B Nguyen, Ximing Du, Ellen M Olzomer, Rhonda Farrell, Frances L Byrne, Hongyuan Yang, Andrew J Brown

Faculty, Staff and Student Publications

Cholesterol is essential for both normal cell viability and cancer cell proliferation. Aberrant activity of squalene monooxygenase (SM, also known as squalene epoxidase), the rate-limiting enzyme of the committed cholesterol synthesis pathway, is accordingly implicated in a growing list of cancers. We previously reported that hypoxia triggers the truncation of SM to a constitutively active form, thus preserving sterol synthesis during oxygen shortfalls. Here, we show SM truncation is upregulated and correlates with the magnitude of hypoxia in endometrial cancer tissues, supporting the in vivo relevance of our earlier work. To further investigate the pathophysiological consequences of SM truncation, we …

Faculty, Staff and Student Publications

The agr quorum-sensing system links Staphylococcus aureus metabolism to virulence, in part by increasing bacterial survival during exposure to lethal concentrations of H2O2, a crucial host defense against S. aureus. We now report that protection by agr surprisingly extends beyond post-exponential growth to the exit from stationary phase when the agr system is no longer turned on. Thus, agr can be considered a constitutive protective factor. Deletion of agr resulted in decreased ATP levels and growth, despite increased rates of respiration or fermentation at appropriate oxygen tensions, suggesting that Δagr cells undergo a shift towards a hyperactive metabolic …

Sars-Cov-2 Omicron: Viral Evolution, Immune Evasion, And Alternative Durable Therapeutic Strategies, Hailong Guo, Sha Ha, Jason W Botten, Kai Xu, Ningyan Zhang, Zhiqiang An, William R Strohl, John W Shiver, Tong-Ming Fu

Faculty, Staff and Student Publications

Since the SARS-CoV-2 Omicron virus has gained dominance worldwide, its continual evolution with unpredictable mutations and patterns has revoked all authorized immunotherapeutics. Rapid viral evolution has also necessitated several rounds of vaccine updates in order to provide adequate immune protection. It remains imperative to understand how Omicron evolves into different subvariants and causes immune escape as this could help reevaluate the current intervention strategies mostly implemented in the clinics as emergency measures to counter the pandemic and, importantly, develop new solutions. Here, we provide a review focusing on the major events of Omicron viral evolution, including the features of spike …
