A Bioengineered Probiotic For The Oral Delivery Of A Peptide Kv13 Channel Blocker To Treat Rheumatoid Arthritis, Yuqing Wang, Duolong Zhu, Laura C Ortiz-Velez, Jacob L Perry, Michael W Pennington, Joseph M Hyser, Robert A Britton, Christine Beeton

Faculty, Staff and Students Publications

New therapeutics that combine efficacy with limited side effects and can be delivered noninvasively are needed to adequately treat patients with rheumatoid arthritis (RA) and other autoimmune diseases. Kv1.3 channel-expressing CCR7− effector memory T (TEM) lymphocytes are significant players in the pathogenesis of multiple autoimmune diseases, and blocking Kv1.3 reduces disease severity in rat models of RA and patients with plaque psoriasis. However, peptide therapeutics require repeated injections, reducing patient compliance. We used a bioengineered Lactobacillus reuteri as an oral delivery method of a Kv1.3 blocker for immunomodulation in rat models of atopic dermatitis and RA. This study demonstrates a …

Background: Taking fewer than the widely promoted "10 000 steps per day" has recently been associated with lower risk of all-cause mortality. The relationship of steps and cardiovascular disease (CVD) risk remains poorly described. A meta-analysis examining the dose-response relationship between steps per day and CVD can help inform clinical and public health guidelines.

Methods: Eight prospective studies (20 152 adults [ie, ≥18 years of age]) were included with device-measured steps and participants followed for CVD events. Studies quantified steps per day and CVD events were defined as fatal and nonfatal coronary heart disease, stroke, and heart failure. Cox proportional …

Disabling Uncompetitive Inhibition Of Oncogenic Idh Mutations Drives Acquired Resistance, Junhua Lyu, Yuxuan Liu, Lihu Gong, Mingyi Chen, Yazan F Madanat, Yuannyu Zhang, Feng Cai, Zhimin Gu, Hui Cao, Pranita Kaphle, Yoon Jung Kim, Fatma N Kalkan, Helen Stephens, Kathryn E Dickerson, Min Ni, Weina Chen, Prapti Patel, Alice S Mims, Uma Borate, Amy Burd, Sheng F Cai, C Cameron Yin, M James You, Stephen S Chung, Robert H Collins, Ralph J Deberardinis, Xin Liu, Jian Xu

Mutations in IDH genes occur frequently in acute myeloid leukemia (AML) and other human cancers to generate the oncometabolite R-2HG. Allosteric inhibition of mutant IDH suppresses R-2HG production in a subset of patients with AML; however, acquired resistance emerges as a new challenge, and the underlying mechanisms remain incompletely understood. Here we establish isogenic leukemia cells containing common IDH oncogenic mutations by CRISPR base editing. By mutational scanning of IDH single amino acid variants in base-edited cells, we describe a repertoire of IDH second-site mutations responsible for therapy resistance through disabling uncompetitive enzyme inhibition. Recurrent mutations at NADPH …

A Molecular Switch Between Mammalian Mll Complexes Dictates Response To Menin-Mll Inhibition, Yadira M Soto-Feliciano, Francisco J Sánchez-Rivera, Florian Perner, Douglas W Barrows, Edward R Kastenhuber, Yu-Jui Ho, Thomas Carroll, Yijun Xiong, Disha Anand, Alexey A Soshnev, Leah Gates, Mary Clare Beytagh, David Cheon, Shengqing Gu, X Shirley Liu, Andrei V Krivtsov, Maximiliano Meneses, Elisa De Stanchina, Richard M Stone, Scott A Armstrong, Scott W Lowe, C David Allis

Faculty, Staff and Student Publications

Menin interacts with oncogenic MLL1-fusion proteins, and small molecules that disrupt these associations are in clinical trials for leukemia treatment. By integrating chromatin-focused and genome-wide CRISPR screens with genetic, pharmacologic, and biochemical approaches, we discovered a conserved molecular switch between the MLL1-Menin and MLL3/4-UTX chromatin-modifying complexes that dictates response to Menin-MLL inhibitors. MLL1-Menin safeguards leukemia survival by impeding the binding of the MLL3/4-UTX complex at a subset of target gene promoters. Disrupting the Menin-MLL1 interaction triggers UTX-dependent transcriptional activation of a tumor-suppressive program that dictates therapeutic responses in murine and human leukemia. Therapeutic reactivation of this program using CDK4/6 inhibitors …

Dance/Movement Therapy As A Holistic Approach To Diminish Health Discrepancies And Promote Wellness For People With Schizophrenia: A Review Of The Literature, Jacelyn Biondo

Department of Family & Community Medicine Faculty Papers

Individuals with a diagnosis of schizophrenia face a myriad of obstacles to wellness, beginning with diagnostic discrepancies including over- and misdiagnoses on the schizophrenia spectrum. People with schizophrenia experience profound amounts of stigmatization from the general population, their healthcare providers, and even themselves. Such stigmatization creates a barrier for wellness, poorer prognoses, and often limits adherence to physical and mental healthcare. Moreover, it can exacerbate the already stifling symptomatology of their diagnoses, including specific bodily-related symptomatology. Oftentimes, a diagnosis of schizophrenia disrupts one's relationship with their body including a diminished mind-body connection, decreased interoceptive awareness, and thus unsuccessful intra- and …

Clear cell renal cell carcinomas (ccRCCs) represent ∼75% of RCC cases and account for most RCC-associated deaths. Inter- and intratumoral heterogeneity (ITH) results in varying prognosis and treatment outcomes. To obtain the most comprehensive profile of ccRCC, we perform integrative histopathologic, proteogenomic, and metabolomic analyses on 305 ccRCC tumor segments and 166 paired adjacent normal tissues from 213 cases. Combining histologic and molecular profiles reveals ITH in 90% of ccRCCs, with 50% demonstrating immune signature heterogeneity. High tumor grade, along with BAP1 mutation, genome instability, increased hypermethylation, and a specific protein glycosylation signature define a high-risk disease subset, where UCHL1 …

Technology Meets Tils: Deciphering T Cell Function In The -Omics Era, William H Hudson, Andreas Wieland

Faculty, Staff and Students Publications

T cells are at the centerstage of cancer immunology due to their ability to recognize mutations within tumor cells and directly mediate cancer cell killing. Immunotherapies to rejuvenate exhausted T cell responses have transformed the clinical management of several malignancies. In parallel, the development of novel multidimensional analysis platforms such as single-cell RNA-sequencing and high-dimensional flow cytometry has yielded unprecedented insights into immune cell biology. This convergence has revealed substantial heterogeneity of tumor-infiltrating immune cells, both within single tumors, across tumor types, and among cancer patients. Here, we discuss the opportunities and challenges of studying the complex tumor microenvironment with …

Interdependent Progression Of Bidirectional Sister Replisomes In E Coli, Po Jui Chen, Anna B Mcmullin, Bryan J Visser, Qian Mei, Susan M Rosenberg, David Bates

Faculty, Staff and Students Publications

Bidirectional DNA replication complexes initiated from the same origin remain colocalized in a factory configuration for part or all their lifetimes. However, there is little evidence that sister replisomes are functionally interdependent, and the consequence of factory replication is unknown. Here, we investigated the functional relationship between sister replisomes in Escherichia coli, which naturally exhibits both factory and solitary configurations in the same replication cycle. Using an inducible transcription factor roadblocking system, we found that blocking one replisome caused a significant decrease in overall progression and velocity of the sister replisome. Remarkably, progression was impaired only if the block …

Relationship Of Abdominal Circumference And Trunk Length With Spinal Anesthesia Block Height In Geriatric Patients Undergoing Transurethral Resection Of Prostate, Muhammad Yahya, Aliya Ahmed, Iayla Fatima, Muhammad Nasir

Department of Anaesthesia

Introduction: Spinal anesthesia is commonly used for various surgical procedures. Prediction of spinal anesthesia block height is always a challenging task for anesthetists. Higher than desired levels of spinal anesthesia blocks are associated with serious side effects, while inadequate block height does not provide satisfactory surgical anesthesia. In this study, we observed the relationship between the ratio of trunk length (TL) and square of the abdominal circumference (AC²) and spinal anesthesia sensory block height in geriatric patients undergoing transurethral resection of the prostate (TURP).
Material & Methods: This is a cross-sectional study conducted at the Aga Khan University …

Department of Neurosurgery Faculty Papers

Fast ripples (FR) are a biomarker of epileptogenic brain, but when larger portions of FR generating regions are resected seizure freedom is not always achieved. To evaluate and improve the diagnostic accuracy of FR resection for predicting seizure freedom we compared the FR resection ratio (RR) with FR network graph theoretical measures. In 23 patients FR were semi-automatically detected and quantified in stereo EEG recordings during sleep. MRI normalization and co-registration localized contacts and relation to resection margins. The number of FR, and graph theoretical measures, which were spatial (i.e., FR rate-distance radius) or temporal correlational (i.e., FR mutual information), …

Predicting The Risk Of A Clinical Event Using Longitudinal Data: The Generalized Landmark Analysis, Yi Yao, Liang Li, Brad Astor, Wei Yang, Tom Greene

Faculty, Staff and Student Publications

Background: In the development of prediction models for a clinical event, it is common to use the static prediction modeling (SPM), a regression model that relates baseline predictors to the time to event. In many situations, the data used in training and validation are from longitudinal studies, where predictor variables are time-varying and measured at clinical visits. But these data are not used in SPM. The landmark analysis (LA), previously proposed for dynamic prediction with longitudinal data, has interpretational difficulty when the baseline is not a risk-changing clinical milestone, as is often the case in observational studies of chronic disease …

Faculty, Staff and Students Publications

As a zoonotic disease caused by Echinococcus multilocularis larvae, alveolar echinococcosis (AE) is one of the most severe forms of parasitic infection. Over a long evolutional process E. multilocularis has developed complex strategies to escape host immune attack and survive within a host. However, the mechanisms underlying immune evasion remain unclear. Here we investigated the binding activity of E. multilocularis calreticulin (EmCRT), a highly conserved Ca2+-binding protein, to human complement C1q and its ability to inhibit classical complement activation. ELISA, Far Western blotting and immunoprecipitation results demonstrated that both recombinant and natural EmCRTs bound to human C1q, …

Faculty, Staff and Student Publications

Patients with advanced thyroid cancer, including advanced papillary thyroid cancer and anaplastic thyroid cancer (ATC), have low survival rates because of the lack of efficient therapies available that can combat their aggressiveness. A total of 90% of thyroid cancers have identifiable driver mutations, which often are components of the MAPK pathway, including BRAF, RAS, and RET-fusions. In addition, Src is a non-receptor tyrosine kinase that is overexpressed and activated in thyroid cancer, which we and others have shown is a clinically relevant target. We have previously demonstrated that combined inhibition of Src with dasatinib and the MAPK …
