Dpar: Decoupled Graph Neural Networks With Node-Level Differential Privacy, Qiuchen Zhang, Hong Kyu Lee, Jing Ma, Jian Lou, Carl Yang, Li Xiong

Faculty, Staff and Student Publications

Graph Neural Networks (GNNs) have achieved great success in learning with graph-structured data. Privacy concerns have also been raised for the trained models which could expose the sensitive information of graphs including both node features and the structure information. In this paper, we aim to achieve node-level differential privacy (DP) for training GNNs so that a node and its edges are protected. Node DP is inherently difficult for GNNs because all direct and multi-hop neighbors participate in the calculation of gradients for each node via layer-wise message passing and there is no bound on how many direct and multi-hop neighbors …

Programming A Ferroptosis-To-Apoptosis Transition Landscape Revealed Ferroptosis Biomarkers And Repressors For Cancer Therapy, Yaron Vinik, Avi Maimon, Vinay Dubey, Harsha Raj, Ifat Abramovitch, Sergey Malitsky, Maxim Itkin, Avi Ma'ayan, Frank Westermann, Eyal Gottlieb, Eytan Ruppin, Sima Lev

Faculty, Staff and Student Publications

Ferroptosis and apoptosis are key cell-death pathways implicated in several human diseases including cancer. Ferroptosis is driven by iron-dependent lipid peroxidation and currently has no characteristic biomarkers or gene signatures. Here a continuous phenotypic gradient between ferroptosis and apoptosis coupled to transcriptomic and metabolomic landscapes is established. The gradual ferroptosis-to-apoptosis transcriptomic landscape is used to generate a unique, unbiased transcriptomic predictor, the Gradient Gene Set (GGS), which classified ferroptosis and apoptosis with high accuracy. Further GGS optimization using multiple ferroptotic and apoptotic datasets revealed highly specific ferroptosis biomarkers, which are robustly validated in vitro and in vivo. A subset of …

Tofacitinib For The Treatment Of Refractory Immune Checkpoint Inhibitor-Associated Immune Nephritis, Kiran Shivaraj, Amanda Tchakarov, Yanlan Dong, Jamie S Lin

Faculty, Staff and Student Publications

Immune checkpoint inhibitor (ICI)-associated immune nephritis or acute interstitial nephritis (AIN) is one of the rare but known complication of ICI therapy. Guidelines recommend treatment of ICI-associated AIN with steroids, then TNF-alpha inhibitor infliximab. However, some cases are refractory to these therapies, potentially due to insufficient cytokine blockade. This is the first case where a 65-year-old female with metastatic lung adenocarcinoma, requiring high maintenance doses of steroids for immune nephritis was treated with tofacitinib, an oral Janus kinase (JAK) inhibitor. Tofacitinib enabled successful steroid tapering and might be a therapy option for refractory immune nephritis.

Faculty, Staff and Student Publications

Objective: This quasi-experimental study examined the effect of repetitive finger stimulation on brain activation in eight stroke and seven control subjects, measured by quantitative electroencephalogram.

Methods: We applied 5 mins of 2-Hz repetitive bilateral index finger transcutaneous electrical nerve stimulation and compared differences pre- and post-transcutaneous electrical nerve stimulation using quantitative electroencephalogram metrics delta/alpha ratio and delta-theta/alpha-beta ratio.

Results: Between-group differences before and after stimulation were significantly different in the delta/alpha ratio ( z = -2.88, P = 0.0040) and the delta-theta/alpha-beta ratio variables ( z = -3.90 with P < 0.0001). Significant decrease in the delta/alpha ratio and delta-theta/alpha-beta ratio variables after the transcutaneous electrical nerve stimulation was detected only in the stroke group (delta/alpha ratio diff = 3.87, P = 0.0211) (delta-theta/alpha-beta ratio diff = 1.19, P = 0.0074).

Conclusions: The decrease in quantitative electroencephalogram metrics in the stroke …

Gain-of-function mutations activating JAK/STAT signaling are seen in the majority of patients with myeloproliferative neoplasms (MPN), most commonly JAK2V617F. Although clinically approved JAK inhibitors improve symptoms and outcomes in MPNs, remissions are rare, and mutant allele burden does not substantively change with chronic therapy. We hypothesized this is due to limitations of current JAK inhibitors to potently and specifically abrogate mutant JAK2 signaling. We therefore developed a conditionally inducible mouse model allowing for sequential activation, and then inactivation, of Jak2V617F from its endogenous locus using a combined Dre-rox/Cre-lox dual-recombinase system. Jak2V617F deletion abrogates MPN features, induces depletion of mutant-specific hematopoietic …
