Medical Aid In Dying: A Narrative Review Of The Recent Academic Literature In The United States, Anjiya Sulaiman, Courtney Nguyen, Caroline G Snider, Gabriel M Aisenberg

Faculty, Staff and Student Publications

Medical aid in dying (MAiD) is a practice in which a healthcare professional provides assistance to a terminally ill patient seeking to end their life. To assess how academic discourse may shape public opinion and policy in the United States, we conducted a narrative review of the literature published between 2020 and 2024. Articles were categorized as supportive, opposing, or neutral, and patterns were examined across authorship, disciplinary focus, and target populations. Our findings reveal that most recent publications adopt supportive or neutral stances toward MAiD, with a slight increase in opposition beginning in 2022. Authorship discipline strongly influenced position, …

Retrospective Analysis Of Cutaneous Immune-Related Adverse Events Following Checkpoint Inhibitor Therapy In Melanoma Patients Reveals Increased Risk Associated With The Hla-B*51:01 Allele, Mckenzie Dileo, Samantha Oglesby, Cheuk Hong Leung, Kristen E Pauken, Sahira Farooq, Shelby L Kubicki, Macartney Welborn, Sana Zahiruddin, Jun Zou, Kai Cao, Anisha B Patel

Faculty, Staff and Student Publications

Background: While immune checkpoint inhibitors (ICIs) have shown significant efficacy, a common side effect is cutaneous immune-related adverse events (irAEs). This study focuses on exploring the association between specific human leukocyte antigen (HLA) alleles and the development of cutaneous irAEs in melanoma patients undergoing ICI monotherapy and combination therapy. As certain HLA types are indicative of susceptibility to autoimmune diseases, it was hypothesized that HLA typing could serve as a potential screening tool for identifying patients at increased risk for developing irAEs.

Methods: A retrospective chart review was performed of 515 patients with melanoma who underwent ICI therapy, either as …

Tbr2-Dependent Parallel Pathways Regulate The Development Of Distinct Iprgc Subtypes, Takae Kiyama, Ching-Kang Chen, Halit Y Altay, Yu-Jiun Chen, Leviette Sigala, Steven Eliason, Chai-An Mao

Faculty, Staff and Student Publications

The intrinsically photosensitive retinal ganglion cells (ipRGC) are the conduit between the retina and brain regions responsible for non-image-forming and image-forming vision. In mice, six ipRGC subtypes have been discovered based on morphological characteristics, functions, and molecular profiles. All ipRGCs arise from Tbr2-expressing RGCs during developmental stages and subsequently diverge and differentiate into the six mature, distinct subtypes in adult retinas. However, the cellular and molecular mechanisms controlling the formation and maturation of the six ipRGC subtypes remain elusive. Here, we demonstrate that two Tbr2-dependent transcription factors, Iroquois‑related homeobox 1 (Irx1) and T-box containing factor 20 (Tbx20), are key downstream …

Small cell transformation has been described as a resistance mechanism to targeted therapy treated in patients with EGFR-mutated NSCLC and less often reported with those with other actionable oncogenic alterations, including ALK-rearranged NSCLC. Given lack of standard-of-care treatments for patients with actionable oncogenic alteration NSCLC transformed to SCLC, this remains a challenge and unmet need for treating these patients.

Here, we present a case of a patient with ALK-rearranged NSCLC with transformation to SCLC, who has progressed on several lines of therapies and successfully treated with tarlatamab to elicit and maintain clinical benefit, including intracranial response.

A Comparative Study Of Statistical Methods For Identifying Differentially Expressed Genes In Spatial Transcriptomics, Yishan Wang, Chenxuan Zang, Ziyi Li, Charles C Guo, Dejian Lai

Faculty, Staff and Student Publications

Spatial transcriptomics (ST) provides unprecedented insights into gene expression patterns while retaining spatial context, making it a valuable tool for understanding complex tissue architectures, such as those found in cancers. Seurat, by far the most popular tool for analyzing ST data, uses the Wilcoxon rank-sum test by default for differential expression analysis. However, as a nonparametric method that disregards spatial correlations, the Wilcoxon test can lead to inflated false positive rates and misleading findings. This limitation highlights the need for a more robust statistical approach that effectively incorporates spatial correlations. To this end, we propose a Generalized Estimating Equations (GEE) …

Identification Of Raptor And Gli1 As Usp37 Substrates Highlight Its Context-Specific Function In Medulloblastoma Cells, Ashutosh Singh, Donghang Cheng, Amanda R Haltom, Yanwen Yang, Tara Dobson, Veena Rajaram

Faculty, Staff and Student Publications

The USP37 gene encodes a deubiquitylase (DUB), which catalyzes the proteolytic removal of ubiquitin moieties from proteins to modulate their stability, cellular localization or activity. Its expression is downregulated in a subgroup of medulloblastomas driven by constitutive activation of sonic hedgehog (SHH) signaling. Patients with SHH-driven medulloblastomas with elevated expression of the RE1 silencing transcription factor (REST) and reduced expression of USP37 have poor outcomes. In previous studies, we showed sustained proliferation of SHH-medulloblastoma cells due to blockade of terminal cell cycle exit and neuronal differentiation stemming from a failure in USP37-dependent stabilization of its target, the cyclin-dependent kinase inhibitor …

Human fatty acid binding protein‐4 (FABP‐4), a protein elevated in obesity that promotes colon cancer cell invasiveness and metastasis, may be associated with higher mortality in individuals with colorectal cancer (CRC) and may serve as a mediator of the obesity–mortality association in these individuals. We used a causal diagram to inform covariate selection and applied Cox proportional hazards models to estimate hazard ratios (HRs) for CRC‐specific, non‐CRC‐specific, and all‐cause mortality by FABP‐4 levels measured in baseline blood samples from 1371 incident CRC cases from the European Prospective Investigation into Cancer and Nutrition cohort. Competing risk analyses were adapted for CRC …

Tumour-Brain Crosstalk Restrains Cancer Immunity Via A Sensory-Sympathetic Axis, Haohan K Wei, Chuyue D Yu, Bo Hu, Xing Zeng, Hiroshi Ichise, Yu Wang, Ronald N Germain, Rui B Chang, Chengcheng Jin

Faculty, Staff and Student Publications

Body–brain communication has emerged as a key regulator of tissue homeostasis1–5. Solid tumours are innervated by different branches of the peripheral nervous system and increased tumour innervation is associated with poor cancer outcomes6–8. However, it remains unclear how the brain senses and responds to tumours in peripheral organs, and how tumour–brain communication influences cancer immunity. Here we identify a tumour–brain axis that promotes oncogenesis by establishing an immune-suppressive tumour microenvironment. Combining genetically engineered mouse models with neural tracing, tissue imaging and single-cell transcriptomics, we demonstrate that lung adenocarcinoma induces innervation and functional …

Prognosis in therapy‐related acute myeloid leukemia (T‐AML) remains poor, but understanding outcomes with venetoclax (VEN)‐based therapy is relevant. We retrospectively analyzed 317 adult patients with newly diagnosed T‐AML focusing on lower intensity therapy (LIT) VEN‐containing regimens. Patients with an antecedent myeloid disorder before AML diagnosis were excluded. The median age was 69 years (range 21–92); 50% evaluated patients had a complex karyotype, and 40% evaluated patients had a TP53 mutation. Composite complete response rates were higher with LIT + VEN compared to LIT (58% vs. 40%, P = 0.003) but were similar in intensive chemotherapy (IC) + VEN versus IC …

Recurrent liver-metastatic colorectal cancer contributes to high mortality. Recurrence occurs when dormant, microscopic residual disease survives initial treatment to escape dormancy. In their dormant, microscopic state within the liver, these metastatic lesions are undetectable by clinical diagnostic imaging until they form overt, chemoresistant metastases. Therefore, understanding the molecular mechanisms underlying dormancy in colorectal cancer liver metastases is a significant knowledge gap, motivating the engineering of nuanced in vitro models of disease. The current work presents an engineered model of liver-metastatic colorectal cancer dormancy. Decellularized extracellular matrix (dECM) scaffolds are used to provide microscopic colorectal cancer cell clusters with a biomimetic, …
