Car-Macrophage Cell Therapy: A New Era Of Hope For Pancreatic Cancer, Daoyan Wei, Liang Wang, Yi Liu, Xiangsheng Zuo, Xiling Shen, Robert S Bresalier

Faculty, Staff and Student Publications

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest malignancies, characterized by late diagnosis, early metastasis, and resistance to conventional therapies. A major barrier to effective treatment is its desmoplastic and immunosuppressive tumor microenvironment (TME), which restricts T cell infiltration and dampens responses to immune checkpoint inhibitors (ICIs). These features highlight the urgent need for innovative immunotherapeutic strategies capable of overcoming PDAC's immunologic and physical barriers. Chimeric antigen receptor (CAR)-macrophage (CAR-M) therapy has emerged as a promising approach to address these challenges. Unlike CAR-T or CAR-NK cells, CAR-Ms can efficiently infiltrate tumors, remodel the TME, phagocytose tumor cells, and stimulate …

Impaired Rest-Activity Rhythm Characteristics Predict Higher Risk Of Incident Type 2 Diabetes In Uk Biobank Participants, Chris Ho Ching Yeung, Alison K Wright, Daniel P Windred, Angus C Burns, Andrew J K Phillips, Sean W Cain, Martin K Rutter, Qian Xiao

Faculty, Staff and Student Publications

Objective: Circadian rhythms play a key role in metabolic health. Rest-activity rhythms, which are in part driven by circadian rhythms, may be associated with diabetes risk. There is a need for large prospective studies to comprehensively examine different rest-activity metrics to determine their relative strength in predicting risk of incident type 2 diabetes.

Research design and methods: In actigraphy data from 83,887 UK Biobank participants, we applied both parametric and nonparametric algorithms to derive 13 different metrics characterizing different aspects of rest-activity rhythm. Diabetes cases were identified using both self-reported data and health records. We used Cox proportional hazards models …

Although both short and long sleep duration are associated with elevated hypertension risk, our understanding of their interplay with biological pathways governing blood pressure remains limited. To address this, we carried out genome-wide cross-population gene-by-short-sleep and long-sleep duration interaction analyses for three blood pressure traits (systolic, diastolic, and pulse pressure) in 811,405 individuals from diverse population groups. We discovered 22 novel gene-sleep duration interaction loci for blood pressure, mapped to 23 genes. Investigating these genes' functional implications shed light on neurological, thyroidal, bone metabolism, and hematopoietic pathways that necessitate future investigation for blood pressure management that caters to sleep health …

White adipose tissue (WAT) fibrosis occurring in obesity contributes to the inflammatory and metabolic comorbidities of insulin resistance and type 2 diabetes, yet the mechanisms involved remain poorly understood. Here, we report a role for the broadly conserved miRNA miR-30a as a regulator of WAT fibrosis and systemic glucose metabolism. Mice modified to express miR-30a at elevated levels in adipose tissues maintain insulin sensitivity coupled with reduced fatty liver disease when fed a high-fat diet. These effects were attributable to cell-autonomous functions of miR-30a that potently increase expression of adipocyte-specific genes. Proteomic screening revealed miR-30a limits profibrotic programs in subcutaneous …

Mir-302a/B/D-3p Differentially Expressed During Frontonasal Development Is Sensitive To Retinoic Acid Exposure, Chihiro Iwaya, Akiko Suzuki, Goo Jun, Junichi Iwata

Faculty, Staff and Student Publications

Any failure in frontonasal development can lead to malformations at the middle facial region, such as frontonasal dysplasia, midfacial clefts, and hyper/hypotelorism. Various environmental factors influence morphogenesis through epigenetic regulations, including the action of noncoding microRNAs (miRNAs). However, it remains unclear how miRNAs are involved in the frontonasal development. In our analysis of publicly available miRNA-seq and RNA-seq datasets, we found that miR-28a-5p, miR-302a-3p, miR-302b-3p, and miR-302d-3p were differentially expressed in the frontonasal process during embryonic days 10.5 to 13.5 (E10.5–E13.5) in mice. Overexpression of these miRNAs led to a suppression of cell proliferation in cultured mouse embryonic frontonasal mesenchymal …

Cat: A Conditional Association Test For Microbiome Data Using A Permutation Approach, Yushu Shi, Liangliang Zhang, Kim-Anh Do, Robert R Jenq, Christine B Peterson

Faculty, Staff and Student Publications

In microbiome analysis, researchers often seek to identify taxonomic features associated with an outcome of interest. However, microbiome features are intercorrelated and linked by phylogenetic relationships, making it challenging to assess the association between an individual feature and an outcome. This paper proposes a novel conditional association test, CAT, that can account for other features and phylogenetic relatedness when testing the association between a feature and an outcome. CAT adopts a permutation approach, measuring the importance of a feature in predicting the outcome by permuting operational taxonomic unit/amplicon sequence variant counts belonging to that feature from the data and quantifying …

Smelling is a human sense, expressing strong sexual dimorphisms. We aim to improve the knowledge of the genetics of human olfactory perception by performing an exploratory genome-wide association meta-analysis of up to 21,495 individuals of European ancestry. By sex-stratified and overall analysis of the identification of twelve odours and an identification score, we discovered ten independent loci, seven of them novel, with trait-wise genome-wide significance (p <  5 × 10−8) involving five odours. Seven of these loci, including four novel ones, are also significant using a stricter study-wide significance threshold (p <  3.85 × 10−9). Loci were predominantly located within clusters of olfactory receptors. Two loci were female-specific while one was sex-differential with respective candidate genes containing androgen response elements. Two-sample Mendelian randomization was applied to search for causal relationships between sex hormones, odour identification and neurodegenerative diseases. A causal negative effect was detected for Alzheimer’s disease on the identification score. These findings deepen our understanding of the genetic basis of olfactory perception and its interaction with sex, prioritizing mechanisms for further molecular research.

Heat Shock Induces Alternative Polyadenylation Through Dynamic Dna Methylation And Chromatin Looping, Emily E Fink, Yi Zhang, Briana Santo, Anwita Siddavatam, Rosie Ou, Vishal Nanavaty, Byron H Lee, Angela H Ting

Faculty, Staff and Student Publications

Alternative cleavage and polyadenylation (APA) is a gene regulatory mechanism used by cells under stress to upregulate proteostasis-promoting transcripts, but how cells achieve this remains poorly understood. Previously, we elucidated a DNA methylation-regulated APA mechanism, in which gene body DNA methylation enhances distal poly(A) isoform expression by blocking CCCTC-binding factor (CTCF) binding and chromatin loop formation at APA control regions. We hypothesized that DNA methylation-regulated APA is one mechanism cells employ to induce proteostasis-promoting poly(A) isoforms. At the DNAJB6 cochaperone locus, acute heat shock resulted in binding of stress response transcription factors heat shock factor 1, ATF6, and YY1 at …

All biological processes, from embryonic development to cancer, are tightly controlled by the interactions between genetics and epigenetics. An array of epigenetic modifications, such as DNA methylation, histone/chromatin modifications, and noncoding RNA-mediated targeting, are essential to regulate the heritable changes that occur during multiple cellular processes. A failure in proper regulation results in inappropriate gene expression that ultimately leads to pathological states. Groundbreaking advances in genomics and transcriptomics have revealed the potential involvement of epigenetics in various physiological and pathological states. The promising clinical and preclinical results shown by epigenetics drugs further underscore the central role of epigenetics in multiple …

The rate of weight reduction during obesity treatment declines over time and eventually reaches a weight plateau. We investigated factors associated with time to weight plateau (TTWP) in tirzepatide-treated participants with obesity or overweight in a post-hoc analysis of SURMOUNT-1 and SURMOUNT-4 trials. Participants adherent to tirzepatide treatment and achieving ≥5% weight loss by primary endpoint (week 72 SURMOUNT-1; week 88 SURMOUNT-4) were included. Weight plateau was defined as a weight change < 5% over a 12-week interval and all subsequent 12-week intervals. TTWP was time from randomization to the start of the first 12-week interval. Association between baseline characteristics and TTWP was assessed. Overall, 1438 participants in SURMOUNT-1 and 259 in SURMOUNT-4 were included. Across BMI categories (overweight, class I, II, and III), median TTWP in SURMOUNT-1 was 24.3, 26.0, 36.1, and 36.1 weeks, respectively (p < .05, class II and III vs. overweight). By week 72, 90.2%, 88.9%, 87.6%, and 87.8% of participants in SURMOUNT-1 had reached a weight plateau across respective BMI categories [Correction added on 22 January 2025, after first online publication: The "72%" has been changed to "72" in this version.]. Higher doses of tirzepatide (10/15 mg), younger age, and female sex were more likely to reach a weight plateau later. Results in SURMOUNT-4 were similar. In this post-hoc analysis, most participants reached a weight plateau by week 72. Higher doses of tirzepatide, younger age, and female sex were associated with a longer TTWP. Further research into modifiers of weight reduction phases with tirzepatide may inform treatment decisions for its use in chronic weight management.
