Anti-retroviral therapy (ART) has decreased human immunodeficiency virus (HIV)-1-associated morbidity. However, despite ART, immune cells remain latently infected, leading to chronic inflammation and HIV-1-associated comorbidities. New strategies are needed to target viral proteins and inflammation. We found activation of Notch3 in renal cells of the HIV-1 transgenic mouse model (HIV-Tg26) and in patients with HIV-associated nephropathy. We hypothesized that targeting NOTCH3 activation constitutes an effective therapy for HIV-related chronic kidney disease. We generated HIV-Tg26 mice with Notch3 knocked out (Tg-N3KO). Compared to HIV-Tg26 mice at 3 months, Tg-N3KO mice showed a marked reduction in renal injury, skin lesions and mortality …

MYCN-amplification is a genetic hallmark of ~40% of high-risk neuroblastomas (NBs). Altered glycosylation is a common feature of adult cancer progression, but little is known about how genetic signatures such as MYCN-amplification alter glycosylation profiles. Herein, matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) revealed increased core fucosylated glycan abundance within neuroblast-rich regions of human MYCN-amplified NB tumors. GDP-mannose 4,6-dehydratase (GMDS) is responsible for the first-committed and rate-limiting step of de novo GDP-fucose synthesis. High GMDS expression was found to be associated with poor patient survival, advanced stage disease, and MYCN-amplification in human NB tumors. Chromatin immunoprecipitation and promoter reporter assays …

The rising incidence of advanced-stage colorectal cancer (CRC) and poor survival outcomes necessitate new and effective therapies. Immune checkpoint inhibitors (ICIs), specifically anti-PD-1 therapy, show promise, yet clinical determinants of a positive response are suboptimal. Here, we identify microRNA-155 (miR-155) as necessary for CD8 + T cell-infiltrated tumors through an unbiased in vivo CRISPR-Cas9 screen identifying functional tumor antigen-specific CD8+ T cell-expressed microRNAs. T cell miR-155 is required for anti-PD-1 responses and for a vital intratumor CD8 + T cell differentiation cascade by repressing Ship-1, inhibiting Tcf-1 and stemness, and subsequently enhancing Cxcr6 expression, anti-tumor immunity, and effector functions. Based …

Staying Sane In The Membrane: Neutral Sphingomyelinase 2 As A Master Regulator Of Plasma Membrane Ceramide, Zainuddin Quadri, Erhard Bieberich

Markey Cancer Center Faculty Publications

Ceramide, a key signaling sphingolipid in the plasma membrane, plays a pivotal role in fundamental cellular processes such as adhesion, polarity, and programmed cell death. The generation of plasma membrane ceramide is largely attributed to the activity of two types of sphingomyelinases: neutral sphingomyelinase 2 (nSMase2, Smpd3) and acid sphingomyelinase (aSMase, Smpd1). While many studies have explored ceramide generation following experimental activation of these enzymes, the mechanisms governing basal or steady- state ceramide levels have remained poorly understood. Using an innovative mass spectrometry approach developed in the Canals’ lab, the team has quantified the distinct contributions of nSMase2 and aSMase …

Bilirubin Bioconversion To Urobilin In The Gut-Liver-Kidney Axis: A Biomarker For Insulin Resistance In The Cardiovascular-Kidney-Metabolic (Ckm) Syndrome, Zachary A. Kipp, Olufunto O. Badmus, David E. Stec, Brantley Hall, Terry D. Hinds Jr.

Markey Cancer Center Faculty Publications

The rising rates of obesity worldwide have increased the incidence of cardiovascular disease (CVD), making it the number one cause of death. Higher plasma bilirubin levels have been shown to prevent metabolic dysfunction and CVD. However, reducing levels leads to deleterious outcomes, possibly due to reduced bilirubin half-life that escalates the production of its catabolized product, urobilinogen, produced by gut bacteria and naturally oxidized to urobilin. Recent findings suggest that the involvement of the microbiome catabolism of bilirubin to urobilin and its absorption via the hepatic portal vein contributes to CVD, suggesting a liver-gut axis involvement. We discuss the studies …

Ddo-Adjuvanted Influenza A Virus Nucleoprotein Mrna Vaccine Induces Robust Humoral And Cellular Type 1 Immune Responses And Protects Mice From Challenge, Victoria Gnazzo, Hanaa Saleh, Ítalo A. Castro, Adrianus C. M. Boon, Amelia K. Pinto, James D. Brien, Carolina B. López

Markey Cancer Center Faculty Publications

A challenge in viral vaccine development is to produce vaccines that generate both neutralizing antibodies to prevent infection and cytotoxic CD8+ T-cells that target conserved viral proteins and can eliminate infected cells to control virus spread. mRNA technology offers an opportunity to design vaccines based on conserved CD8-targeting epitopes, but achieving robust antigen-specific CD8+ T-cells remains a challenge. Here, we tested the viral-derived oligonucleotide DDO268 as an adjuvant in the context of a model influenza A virus (IAV) nucleoprotein (NP) mRNA vaccine in C57BL/6 mice. DDO268 when co-packaged with mRNA in lipid nanoparticles is sensed by RIG I-like receptors and …

The Mitochondria As An Emerging Target Of Self- Renewal In T-Cell Acute Lymphoblastic Leukemia, Majd Al-Hamaly, Evelyn Winter, Jessica S. Blackburn

Markey Cancer Center Faculty Publications

Acute lymphocytic leukemia (ALL) is the most common leukemia in children, with the T-cell subtype (T- ALL) accounting for 15% of those cases. Despite advancements in the treatment of T-ALL, patients still face a dismal prognosis following their first relapse. Relapse can be attributed to the inability of chemotherapy agents to eradicate leukemia stem cells (LSC), which possess self-renewal capabilities and are responsible for the long-term maintenance of the disease. Mitochondria have been recognized as a therapeutic vulnerability for cancer stem cells, including LSCs. Mitocans have shown promise in T-ALL both in vitro and in vivo, with some currently in …

• Background (83 words): Standard delivery protocols for most prenatally diagnosed CCHD is induction of labor at 39 weeks with aims of a vaginal delivery (VD) near a tertiary care center. There is no benefit to planned Cesarean delivery (CD) over VD for most infants with CCHD. However, longer durations of labor (DOL) in CCHD have been described as a risk factor for umbilical artery (UA) acidosis. We aim to describe the relationship between DOL and UA pH and neonatal outcomes in those with prenatally diagnosed CCHD. • Methods (150 words): Retrospective chart review of prenatally diagnosed with CCHD born …

Tracking Community Outreach And Engagement Activities Among National Cancer Institute-Designated Cancer Centers, Todd Burus, Caree Mcafee, Pamela Hull, Amy Leader, Christopher Mcnair

Kimmel Cancer Center Faculty Papers

The National Cancer Institute's (NCI) Cancer Center Support Grant mandates that NCI-designated cancer centers establish a Community Outreach and Engagement (COE) component to help direct efforts at reducing cancer burden within their catchment areas. Despite the critical role of COE offices, little is known about how they track and evaluate outreach activities and outcomes. We gathered information on current practices from representatives of 40 out of 65 COE offices using an online survey. Although nearly all responding centers (97.5%) tracked COE activities, no consensus existed on resources used, and satisfaction with current solutions was mixed (51.0% not satisfied). Respondents expressed …

Anaesthesiology, East Africa

Severity of illness scores in the critical care context have evolved to serve multiple functions. These scores enable risk-adjusted outcomes to be benchmarked for the assessment of intensive care unit (ICU) performance, inform resource allocation, and enable the characterization of disease severity. Numerous illness severity scores have been developed to optimize calibration at the national level, but few studies have examined the international application of such scores.()

The COVID-19 pandemic demonstrated the value of benchmarking outcomes across heterogeneous populations and across various health care systems. Severity of illness scores were widely used to describe trial populations, assess treatment effects and …

Parkinson’s disease (PD) is an incurable, progressive and common movement disorder that is increasing in incidence globally because of population aging. We hypothesized that the landscape of rare, protein-altering variants could provide further insights into disease pathogenesis. Here we performed whole-exome sequencing followed by gene-based tests on 4,298 PD cases and 5,512 controls of Asian ancestry. We showed that GBA1 and SMPD1 were significantly associated with PD risk, with replication in a further 5,585 PD cases and 5,642 controls. We further refined variant classification using in vitro assays and showed that SMPD1 variants with reduced enzymatic activity display the strongest …

Background and purpose: Angiogenesis is a pathological component of neovascular age-related macular degeneration. Current therapies, although successful, are prone to high levels of patient non-response and a loss of efficacy over time, indicating the need to explore other therapeutic avenues. We have shown that an interaction between syndecan-2 and the tyrosine phosphatase receptor CD148 (RTP Type J) results in the ablation of angiogenesis. Here we exploit this pathway to develop a peptide activator of CD148 as a therapy for neovascular age-related macular degeneration.

Experimental approach: We tested a peptide (QM107) derived from syndecan-2 in a variety of angiogenesis models and …
