Privacy-Preserving Framework For Genomic Computations Via Multi-Key Homomorphic Encryption Mar 2025

Privacy-Preserving Framework For Genomic Computations Via Multi-Key Homomorphic Encryption

Faculty, Staff and Student Publications

Motivation: The affordability of genome sequencing and the widespread availability of genomic data have opened up new medical possibilities. Nevertheless, they also raise significant concerns regarding privacy due to the sensitive information they encompass. These privacy implications act as barriers to medical research and data availability. Researchers have proposed privacy-preserving techniques to address this, with cryptography-based methods showing the most promise. However, existing cryptography-based designs lack (i) interoperability, (ii) scalability, (iii) a high degree of privacy (i.e. compromise one to have the other), or (iv) multiparty analyses support (as most existing schemes process genomic information of each party individually). Overcoming …

Learning Directed Acyclic Graphs For Ligands And Receptors Based On Spatially Resolved Transcriptomic Data Of Ovarian Cancer, Shrabanti Chowdhury, Sammy Ferri-Borgogno, Peng Yang, Wenyi Wang, Jie Peng, Pei Wang

Faculty, Staff and Student Publications

To unravel the mechanism of immune activation and suppression within tumors, a critical step is to identify transcriptional signals governing cell-cell communication between tumor and immune/stromal cells in the tumor microenvironment. Central to this communication are interactions between secreted ligands and cell-surface receptors, creating a highly connected signaling network among cells. Recent advancements in in situ-omics profiling, particularly spatial transcriptomic (ST) technology, provide unique opportunities to directly characterize ligand-receptor signaling networks that power cell-cell communication. In this paper, we propose a novel statistical method, LRnetST, to characterize the ligand-receptor interaction networks between adjacent tumor and immune/stroma cells based on ST …

As colorectal cancer remains a leading cause of cancer-related death, identifying therapeutic targets and approaches is essential to improve patient outcomes. The EGFR ligand epiregulin (EREG) is highly expressed in RAS wild-type (WT) and mutant colorectal cancer, with minimal expression in normal tissues, making it an attractive target for antibody-drug conjugate (ADC) development. In this study, we produced and purified an EREG mAb, H231, which had high specificity and affinity for human and mouse EREG. H231 also internalized to lysosomes, which is important for ADC payload release. ImmunoPET and ex vivo biodistribution studies showed significant tumor uptake of zirconium-89-labeled H231, …

Systematic multi-omics analysis revealed ancestry-dependent molecular alterations, but their impact on the efficacy of anti-cancer treatment is yet largely unknown. Here, we analyzed clinical trials from ClinicalTrials.gov and found that only 8,779/102,721 (8.5%) oncology clinical trials posted information on enrollment by race/ethnicity. The underrepresentation of non-White populations suggests that it remains challenging to determine differences in the efficacy of anti-tumor treatments among different racial groups. Through a comprehensive analysis of clinically actionable genes, imputed drug responses, and immune features, we identified potential differences in treatment response to targeted, chemo and immunotherapies between different ancestral populations. Further analysis of multiple independent …

Triple-negative breast cancer (TNBC) is a highly metastatic subtype of breast cancer. The epithelial-to-mesenchymal transition is a nonbinary process in the metastatic cascade that generates tumor cells with both epithelial and mesenchymal traits known as hybrid EM cells. Recent studies have elucidated the enhanced metastatic potential of cancers featuring the hybrid EM phenotype, highlighting the need to uncover molecular drivers and targetable vulnerabilities of the hybrid EM state. Here, we discovered that hybrid EM breast tumors are enriched in CD38, an immunosuppressive molecule associated with worse clinical outcomes in liquid malignancies. Altering CD38 expression in tumor cell impacted migratory, invasive, …

A Novel Sensitivity Maximization At A Given Specificity Method For Binary Classifications, Seyyed Mahmood Ghasemi, Chunhui Gu, Johannes F Fahrmann, Samir Hanash, Kim-Anh Do, Ehsan Irajizad

Faculty, Staff and Student Publications

In the cancer early detection field, logistic regression (LR) is a frequently used approach to establish a combination rule that differentiates cancer from noncancer. However, the application of LR relies on a maximum likelihood approach, which may not yield optimal combination rules for maximizing sensitivity at a clinically desirable specificity and vice versa. In this article, we have developed an improved regression framework, sensitivity maximization at a given specificity (SMAGS), for binary classification that finds the linear decision rule, yielding the maximum sensitivity for a given specificity or the maximum specificity for a given sensitivity. We additionally expand the framework …

Tubulin Transforms Tau And Α-Synuclein Condensates From Pathological To Physiological, Kyoung-Jae Choi, Josephine C Ferreon, Allan Chris M Ferreon

Faculty, Staff and Students Publications

Proteins phase-separate to form condensates that partition and concentrate biomolecules into membraneless compartments. These condensates can exhibit dichotomous behaviors in biology by supporting cellular physiology or instigating pathological protein aggregation 1–3 . Tau and α- synuclein (αSyn) are neuronal proteins that form heterotypic (Tau:αSyn) condensates associated with both physiological and pathological processes. Tau and αSyn functionally regulate microtubules 8–12 , but are also known to misfold and co-deposit in aggregates linked to various neurodegenerative diseases 4,5,6,7 , which highlights the paradoxically ambivalent effect of Tau:αSyn condensation in health and disease. Here, we show that tubulin modulates Tau:αSyn condensates by promoting …

Disrupting Tymp-Mediated Pathways To Block Lymph Node Metastasis In Ovarian Cancer, Emine Bayraktar Mar 2025

Disrupting Tymp-Mediated Pathways To Block Lymph Node Metastasis In Ovarian Cancer, Emine Bayraktar

Dissertations and Theses (Open Access)

Historically, ovarian cancer (OC) was thought to metastasize by surface-to-surface spread, but recent developments have yielded a new understanding of the paths of metastatic spread. In epithelial ovarian cancer, the mechanisms driving lymph node (LN) metastasis are poorly understood, and it remains unclear whether omental metastasis occurs in parallel with LN metastasis. Utilizing comparative transcriptomic and proteomic profiling of primary tumors, LN metastases, and omental metastases, we identified significant upregulation of thymidine phosphorylase (TYMP) in LN metastases compared to primary and omental tumor sites. Functional studies in murine models demonstrated that TYMP silencing significantly suppressed LN metastasis, underscoring TYMP as …

PURPOSE: The best possible outcomes in infantile epileptic spasms syndrome require electroclinical remission; however, determining electrographic remission is not straightforward. Although the determination of hypsarrhythmia has inadequate interrater reliability (IRR), the Burden of AmplitudeS and Epileptiform Discharges (BASED) score has shown promise for the reliable interictal assessment of infantile epileptic spasms syndrome. Our aim was to develop a BASED training program and assess the IRR among learners. We hypothesized moderate or better IRR for the final BASED score and the presence or absence of epileptic encephalopathy (+/-EE).

This paper presents an evaluation of predictions submitted for the "HMBS" challenge, a component of the sixth round of the Critical Assessment of Genome Interpretation held in 2021. The challenge required participants to predict the effects of missense variants of the human HMBS gene on yeast growth. The HMBS enzyme, critical for the biosynthesis of heme in eukaryotic cells, is highly conserved among eukaryotes. Despite the application of a variety of algorithms and methods, the performance of predictors was relatively similar, with Kendall's tau correlation coefficients between predictions and experimental scores around 0.3 for a majority of submissions. Notably, the …


Pseudotumor Tensor Fascia Lata Syndrome From Underlying Severe Lumbar Stenosis: A Case Report, Yonghoon Lee Mar 2025

Pseudotumor Tensor Fascia Lata Syndrome From Underlying Severe Lumbar Stenosis: A Case Report, Yonghoon Lee

Faculty, Staff and Students Publications

A pseudotumor of the tensor fascia lata (TFL) describes a rare condition characterized by hypertrophy or pseudohypertrophy of the TFL that can mimic a soft tissue mass. Without the right clinical suspicion, it can be misdiagnosed as a benign or malignant soft tissue tumor, leading to oncologic workups. Unnecessary workups can cause patient distress, waste resources, and delay the management of the condition and its associated symptoms. Here, we describe a 65-year-old male who developed a pseudotumor of the TFL in the setting of severe lumbar spinal stenosis. The etiology for this patient was suspected to be a combination of …
