Department of Surgery Faculty Papers

BACKGROUND: The rising complexity and cost of healthcare in plastic surgery, particularly in resource-intensive procedures like free flap and breast reconstruction, pose significant financial challenges. Time-driven activity-based costing (TDABC) offers a method to accurately assess these costs by mapping each step of the care cycle based on time and resources consumed. Although TDABC has been utilized in high-cost fields such as neurosurgery and spine surgery, its application in plastic surgery remains underexplored. This systematic review evaluates the literature on TDABC use in plastic surgery to identify key cost drivers and propose strategies for cost-efficiency.

METHODS: A systematic review was conducted …

Tumor-initiated emergency granulopoiesis results in expansion of the circulating neutrophil compartment and neutrophil recruitment into the tumor microenvironment (TME), which may in turn promote tumor progression. Although an elevated circulating neutrophil-to-lymphocyte ratio (cNLR) has repeatedly been demonstrated to be an adverse prognostic factor in patients with non-small cell lung cancer (NSCLC), whether this neutrophil expansion in circulation reflects a similar relative neutrophil abundance in the TME remains unclear. We sought to characterize the relationships between cNLR and the intratumoral neutrophil-to-lymphocyte ratio (tNLR), between tNLR and proteogenomic and immune features of NSCLC tumors, and between tNLR and prognosis.We analyzed tNLR (transcriptomic …

The Carsr Two-Component System Directly Controls Radd Expression As A Global Regulator That Senses Bacterial Coaggregation In Fusobacterium Nucleatum, Bibek G C, Chenggang Wu

Faculty, Staff and Student Publications

Two-component systems (TCS) enable bacteria to sense and respond to environmental signals, facilitating rapid adaptation. Fusobacterium nucleatum, a key oral pathobiont, employs the CarSR TCS to modulate coaggregation with various gram-positive partners by regulating the expression of radD, encoding a surface adhesion protein, as revealed by RNA-Seq analysis. However, the direct regulation of the radD-containing operon (radABCD) by the response regulator CarR, the broader CarR regulon, and the signals sensed by this system remain unclear. In this study, chromatin immunoprecipitation followed by high-throughput DNA sequencing (ChIP-seq) identified approximately 161 CarR-enriched loci across the genome and …

Castration-resistant prostate cancer (CRPC) remains an incurable disease in need of improved treatments. CAMKK2 is an emerging therapeutic target whose oncogenic effects in prostate cancer have, to date, been largely attributed to its activation of AMP-activated protein kinase (AMPK). Here, we demonstrate that CAMKK2 promotes prostate cancer growth through an alternative downstream pathway involving CAMKI and CREB. Unbiased transcriptomics identify CREB-mediated transcription as a CAMKK2-regulated process, findings that we validate using diverse molecular, genetic, and pharmacological approaches in vitro and in vivo. CAMKK2 promotes CREB phosphorylation/activation through CAMKIα independently of AMPK, CAMKIV, or other CAMKI isoforms. Functionally, the CREB family …

The Only Constant Is Change: The Role Of Genetic Diversification In Cancer And Beyond, Malgorzata Tyczynska Weh

USF Tampa Graduate Theses and Dissertations

Genetic diversification, the process by which genetic variation arises in a population, is fundamental to evolution by natural selection. Mutation, a central diversification process, fuels adaptation across species, including in cancer. Yet most new mutations are neutral or deleterious on cell fitness, raising the question of how mutation-driven adaptation persists. To explore this paradox, I developed a spatial agent-based model (ABM) in which population fitness emerges from individual cells acquiring mutations at varied rates and with diverse fitness effects. I evaluated model behavior across adaptive states, mutation rates, and distributions of fitness effects. The results show that high mutation rates …

Potential Effect Of Statins As Adjuvant Anti‑Tuberculosis Agents: A Short Communication, Mehwish Hanif, Ayesha Tariq, Laiba Zahoor

Digital Journal of Clinical Medicine

Tuberculosis is a chronic pulmonary infectious disease caused by Mycobacterium tuberculosis and can affect other parts of the body such as bones, brain, and lymph nodes (extra pulmonary Tb). Statins, primarily used for hyperlipidemia, have demonstrated anti-inflammatory and immunomodulatory properties that may help prevent and manage TB. They inhibit HMG-CoA reductase, reduce cholesterol synthesis and interfere with phagocytosis crucial for TB infection. Given the rise in resistance to first-line anti-tubercular therapies, Statins have shown promise as adjunctive agents by potentially shortening treatment duration, reducing adverse effects, and improving outcomes, particularly in immunocompromised and diabetic patients. Based on these findings, Statins …

Usp37 Counteracts Hltf To Protect Damaged Replication Forks And Promote Survival Of Brca1-Deficient Cells And Parp Inhibitor Resistance, Mengfan Tang, Siting Li, Ziqiang Zhu, Chao Wang, Shuai Ding, Huimin Zhang, Min Huang, Sarah Keast, Zhen Chen, Ling Yin, Litong Nie, Dan Su, Xu Feng, Junjie Chen

Faculty, Staff and Student Publications

Poly(ADP-ribose) polymerase inhibitors (PARPi) have greatly improved survival of cancer patients harboring BRCA1 mutations. However, therapy resistance develops via either restoration of homologous recombination or replication fork stabilization. Therapeutic targets to overcome PARPi resistance are critically needed. We identified the deubiquitinase USP37 as a key determinant of PARPi toxicity in BRCA1-deficient cells via whole-genome CRISPR screens. USP37 ablation enhanced PARPi sensitivity in BRCA1-deficient cells and also overcame PARPi resistance due to 53BP1 loss. USP37 interacts with and deubiquitinates replication protein A (RPA) at stalled replication forks to limit excessive RPA accumulation, progressive RPA exhaustion, and the conversion of RPA-coated single-stranded …
