Purpose: Trimodality therapy for muscle-invasive bladder cancer (MIBC) yields similar oncologic outcomes compared to radical cystectomy in appropriately selected patients; however, data regarding locally advanced MIBC (LA-MIBC) is limited. We explored our experience with LA-MIBC undergoing radiation therapy (RT).

Methods: We retrospectively identified 30 patients from an institutional prospectively collated database with non-metastatic, LA-MIBC. Patients with T3-4 N0 or T2-4 N + treated from 2012 to 2022 with definitive-intent RT, who were not candidates for cystectomy were included. Kaplan-Meier analysis was used to estimate time-to-event outcomes, and multivariate analyses were conducted using Cox proportional hazards modeling.

Results: 43 % had …

Apoptotic Extracellular Vesicles Carrying Mif Regulate Macrophage Recruitment And Compensatory Proliferation In Neighboring Epithelial Stem Cells During Tissue Maintenance, Safia A Essien, Ivanshi Ahuja, George T Eisenhoffer

Faculty, Staff and Student Publications

Apoptotic cells can signal to neighboring cells to stimulate proliferation and compensate for cell loss to maintain tissue homeostasis. While apoptotic cell-derived extracellular vesicles (AEVs) can transmit instructional cues to mediate communication with neighboring cells, the molecular mechanisms that induce cell division are not well understood. Here, we show that macrophage migration inhibitory factor (Mif)-containing AEVs regulate compensatory proliferation via ERK signaling in epithelial stem cells of larval zebrafish. Time-lapse imaging showed efferocytosis of AEVs from dying epithelial stem cells by healthy neighboring stem cells. Proteomic and ultrastructure analysis of purified AEVs identified Mif localization on the AEV surface. Pharmacological …

Enriched G4 Forming Repeats In The Human Genome Are Associated With Robust Well-Coordinated Transcription And Reduced Cancer Transcriptome Variation, Ruth B De-Paula, Albino Bacolla, Aleem Syed, John A Tainer

Faculty, Staff and Student Publications

Non-B DNA G-quadruplex (G4) structures with guanine (G) runs of 2 to 4 repeats can trigger opposing experimental transcriptional impacts. Here, we used bioinformatic algorithms to comprehensively assess correlations of steady-state RNA transcript levels with all putative G4 sequence (pG4) locations genome-wide in three mammalian genomes and in normal and tumor human tissues. The human pG4-containing gene set displays higher expression levels than the set without pG4, supporting and extending some prior observations. pG4 enrichment at transcription start sites (TSSs) in human, but not chimpanzee and mouse genomes, suggests possible positive selection pressure for pG4 at human TSS, potentially driving …

Argonaute (AGO), a component of RNA-induced silencing complexes (RISCs), is a representative RNA-binding protein (RBP) known to bind with mature microRNAs (miRNAs) and is directly involved in post-transcriptional gene silencing. However, despite the biological significance of miRNAs, the roles of other miRNA-binding proteins (miRBPs) remain unclear in the regulation of miRNA loading, dissociation from RISCs and extracellular release. In this study, we performed protein arrays to profile miRBPs and identify 118 RBPs that directly bind to miRNAs. Among those proteins, the RBP quaking (QKI) inhibits extracellular release of the mature microRNA let-7b by controlling the loading of let-7b into extracellular …

KRAS inhibitors demonstrate clinical efficacy in pancreatic ductal adenocarcinoma (PDAC); however, resistance is common. Among patients with KRASG12C-mutant PDAC treated with adagrasib or sotorasib, mutations in PIK3CA and KRAS, and amplifications of KRASG12C, MYC, MET, EGFR, and CDK6 emerged at acquired resistance. In PDAC cell lines and organoid models treated with the KRASG12D inhibitor MRTX1133, epithelial-to-mesenchymal transition and PI3K-AKT-mTOR signaling associate with resistance to therapy. MRTX1133 treatment of the KrasLSL-G12D/+; Trp53LSL-R172H/+; p48-Cre (KPC) mouse model yielded deep tumor regressions, but drug resistance ultimately emerged, accompanied by amplifications of Kras, Yap1, Myc, Cdk6, and Abcb1a/b, and co-evolution of drug-resistant transcriptional programs. …

Faculty, Staff and Student Publications

The phosphatidylinositol 3‑kinase/protein kinase B (PI3K/AKT) signaling pathway is critically active in many cell types, both normal and neoplastic. Many small-molecule inhibitors targeting different levels of the PI3K/AKT pathway have been developed for cancer therapy, but their efficacy is reduced by compensatory pathway re-activation mechanisms, and their tolerability by toxic side effects. We studied this problem using cell lines representing diffuse large B-cell lymphoma (SUDHL-4 and OCI-Ly7), a genetically-encoded live-cell reporter of AKT activity, and 3 small-molecule inhibitors targeting different levels of the pathway: idelalisib (PI3Kδ), GSK2334470 (PDPK1), and ipatasertib (AKT). Half-maximal (IC50) concentrations of these inhibitors for AKT activity …

Regulating Adaptive Medical Artificial Intelligence: Can Less Oversight Lead To Greater Compliance?, Jiayi Lai, Liang Xu, Xin Fang, Tinglong Dai

Research Collection Lee Kong Chian School Of Business

As of June 2024, the U.S. Food and Drug Administration (FDA) has approved 950 medical artificial intelligence (AI) devices. The current regulatory framework freezes AI algorithms after approval, requiring new submissions for updates to ensure compliance with Good Machine Learning Practices (GMLP). This approach imposes a significant administrative burden, while hindering the ability of AI algorithms to learn from new data. To address these challenges, the FDA has explored a novel pathway known as Predetermined Change Control Plans (PCCP), allowing developers to outline future changes during initial submissions and exempting approved changes from regulatory review. Yet, the impact of this …

Therapeutic Targeting Of Hypoxia Inducible Factor In Acute Respiratory Distress Syndrome, Thu T Tran, Holger K Eltzschig, Xiaoyi Yuan

Faculty, Staff and Student Publications

Acute respiratory distress syndrome (ARDS) is characterized by bilateral chest infiltration and acute hypoxic respiratory failure. ARDS carries significant morbidity and mortality despite advancements in medical management, calling for the development of novel therapeutic targets. Hypoxia-inducible factor (HIF) is a heterodimeric protein involved in various essential pathways, including metabolic reprogramming, immune modulation, angiogenesis and cell cycle regulation. HIF is routinely degraded in homeostasis conditions via the prolyl hydroxylase domain/von Hippel-Lindau protein pathway. However, HIF is stabilized in ARDS via various mechanisms (oxygen-dependent and independent) as an endogenous protective pathway and plays multifaceted roles in different cell populations. This review focuses …

Bacillus Licheniformis Suppresses Clostridium Perfringens Infection Via Modulating Inflammatory Response, Antioxidant Status, Inflammasome Activation And Microbial Homeostasis In Broilers, Xiao Xiao, Songke Qin, Tiantian Cui, Jinsong Liu, Yanping Wu, Yifan Zhong, Caimei Yang

Faculty, Staff and Student Publications

Pathogenic bacteria infection, especially Clostridium perfringens (C. perfringens), markedly threatened the health of animals, and further caused huge economic loss. In this study, Bacillus licheniformis HJ0135 (BL) was used. Oxford cup bacteriostatic test and inhibitory rate test were conducted to evaluate the antibacterial ability of BL. Results showed the strongest inhibitory role of BL on C. perfringens (P < 0.05). Afterwards, 540 one-day-old yellow-feather broilers (32.7 ± 0.2 g) were randomly allocated into 3 groups, including CON group (basal diet), CP group (basal diet + 1 × 109 CFU C. perfringens in gavage), and BL + CP group (basal diet containing 7.5 × 106 CFU/g BL + 1 × 109 CFU C. perfringens in gavage). At d 70, broilers in the CP and BL + CP groups were treated with C. perfringens by continuously oral administration for 5 d. The experiment lasted for 75 d. The serum, immune organs, jejunal mucosa, and cecal contents were collected for analysis. In vivo experiment showed that BL supplementation markedly improved (P < 0.05) BW, ADG, thymus index, serum immunoglobins and antioxidases, reduced feed conversion ratio (FCR) and serum pro-inflammatory cytokines of C. perfringens-infected broilers. Furthermore, the increased jejunal injury and levels of pro-inflammatory cytokines, decreased gene expressions of tight junction proteins in the jejunal mucosa were significantly alleviated (P < 0.05) by BL. More importantly, the activation of NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasome was inhibited (P < 0.05) by BL to further attenuate jejunal damage. Besides, BL supplementation markedly increased (P < 0.05) the cecal isobutyric acid and isovaleric acid. Microbial analysis showed that BL changed the composition and relative abundances of microbiota in the cecal contents (P < 0.05), especially the short chain fatty acids (SCFAs)-producing bacteria including Eubacterium_coprostanoligenes_group, Megamonas, Faecalibacterium, and Lactobacillus, which further protected against C. perfringens-induced jejunal inflammation in broilers. Our study laid a theoretical basis for the application of probiotics in lessening C. perfringens-related diseases in poultry farming.

Calcineurin Inhibition Enhances Caenorhabditis Elegans Lifespan By Defecation Defects-Mediated Calorie Restriction And Nuclear Hormone Signaling, Priyanka Das, Alejandro Aballay, Jogender Singh

Faculty, Staff and Student Publications

Calcineurin is a highly conserved calcium/calmodulin-dependent serine/threonine protein phosphatase with diverse functions. Inhibition of calcineurin is known to enhance the lifespan of Caenorhabditis elegans through multiple signaling pathways. Aiming to study the role of calcineurin in regulating innate immunity, we discover that calcineurin is required for the rhythmic defecation motor program (DMP) in C. elegans. Calcineurin inhibition leads to defects in the DMP, resulting in intestinal bloating, rapid colonization of the gut by bacteria, and increased susceptibility to bacterial infection. We demonstrate that intestinal bloating caused by calcineurin inhibition mimics the effects of calorie restriction, resulting in enhanced lifespan. …

Faculty, Staff and Student Publications

Immunotherapy has developed into an important modality of modern cancer treatment. Unfortunately, checkpoint inhibitor immunotherapies are currently delivered systemically and require frequent administration, which can result in toxicity and severe, sometimes fatal, adverse events. Localized delivery of immunomodulators for oral cancer and oral potentially malignant disorders offers the promise of maximum therapeutic potential and reduced systemic adverse effects. This review will discuss the limitations of current standard-of-care systemic therapies and highlight research advances in localized, intratumoral delivery platforms for immunotherapy for oral cancer and oral potentially malignant disorders.

We rigorously assessed a comprehensive association testing framework for heteroplasmy, employing both simulated and real-world data. This framework employed a variant allele fraction (VAF) threshold and harnessed multiple gene-based tests for robust identification and association testing of heteroplasmy. Our simulation studies demonstrated that gene-based tests maintained an appropriate type I error rate at α = 0.001. Notably, when 5 % or more heteroplasmic variants within a target region were linked to an outcome, burden-extension tests (including the adaptive burden test, variable threshold burden test, and z-score weighting burden test) outperformed the sequence kernel association test (SKAT) and the original burden …

Diabetes is a major health care challenge, affecting 10% of the global population. One third of patients with diabetes have an ocular complication known as diabetic retinopathy (DR). DR progression to manifestations such as vision-threatening diabetic retinopathy (VTDR) remains the leading cause of blindness in working-aged adults. Yearly DR screening is a universally recommended practice in primary care settings for patients with diabetes, but it is often difficult to implement due to a lack of staffing and screening capacity in primary care. This case study highlights our experience with developing a medical artificial intelligence (AI) software-as-a-medical-device (SaMD) solution for DR …
