Journal ArticleDOI

Jesse Lyons,Jesse Lyons,Phaedra C Ghazi,Alina Starchenko,Alina Starchenko,Alessio Tovaglieri,Katherine R. Baldwin,Emily J. Poulin,Jessica J. Gierut,Casie A. Genetti,Vijay Yajnik,David T. Breault,Douglas A. Lauffenburger,Kevin M. Haigis +13 more
TL;DR: This study suggests that proper differentiation of epithelial cells is an important feature of colonic homeostasis because of its effect on the secretion of inflammatory cytokines.
Journal ArticleDOI
Natural history of Crohn's disease following total colectomy and end ileostomy.
Joanna Lopez,Gauree G. Konijeti,Deanna D. Nguyen,Jenny Sauk,Vijay Yajnik,Ashwin N. Ananthakrishnan +5 more
TL;DR: Up to one-third of patients with CD have overall recurrence of disease after treatment with total colectomy and permanent ileostomy, suggesting there is need to develop algorithms for surveillance and management of this select subgroup of patients.
Journal ArticleDOI
Reduced DOCK4 expression leads to erythroid dysplasia in myelodysplastic syndromes.
Sriram Sundaravel,Ryan Duggan,Tushar D. Bhagat,David L. Ebenezer,Hui Liu,Yiting Yu,Matthias Bartenstein,Madhu Unnikrishnan,Subhradip Karmakar,Ting Chun Liu,Ingrid Torregroza,Thomas Quenon,John Anastasi,Kathy L. McGraw,Andrea Pellagatti,Jacqueline Boultwood,Vijay Yajnik,Andrew S. Artz,Michelle M. Le Beau,Ulrich Steidl,Alan F. List,Todd Evans,Amit Verma,Amittha Wickrema +23 more
TL;DR: It is demonstrated that DOCK4 is underexpressed in MDS bone marrow samples and that the reduced expression is associated with decreased overall survival in patients, and a novel single-cell multispectral flow cytometry assay is developed for evaluation of disrupted F-actin filaments, which can be used for potential early detection of dysplastic cells in M DS.
Journal ArticleDOI
Impact of mode of delivery on outcomes in patients with perianal Crohn's disease.
Alice Cheng,Emily C Oxford,Jenny Sauk,Deanna D. Nguyen,Vijay Yajnik,Sonia Friedman,Sonia Friedman,Ashwin N. Ananthakrishnan +7 more
TL;DR: There was no difference in risk of symptomatic perianal flares in patients with establishedPerianal CD delivering vaginally or through C-section, based on mode of delivery or between pregnant patients with CD and nonpregnant CD controls.
Journal ArticleDOI
Integrated in vivo multiomics analysis identifies p21-activated kinase signaling as a driver of colitis
Jesse Lyons,Jesse Lyons,Douglas K. Brubaker,Douglas K. Brubaker,Phaedra C. Ghazi,Katherine R. Baldwin,Katherine R. Baldwin,Amanda L. Edwards,Myriam Boukhali,Samantha Dale Strasser,Samantha Dale Strasser,Lucia Suarez-Lopez,Lucia Suarez-Lopez,Yi-Jang Lin,Vijay Yajnik,Joseph L. Kissil,Wilhelm Haas,Douglas A. Lauffenburger,Kevin M. Haigis,Kevin M. Haigis +19 more
TL;DR: A multiomics analysis that integrated RNA microarray, total protein mass spectrometry, and phosphoproteomics analyses of tissues isolated from a mouse model of colitis identified Pak as a potential therapeutic target in IBD.
