TL;DR: Treatment with FMT was associated with favorable changes in immune cell infiltrates and gene expression profiles in both the gut lamina propria and the tumor microenvironment, which have implications for modulating the gut microbiota in cancer treatment.
Journal ArticleDOI
Radiation induces proinflammatory dysbiosis: transmission of inflammatory susceptibility by host cytokine induction
Shiran Gerassy-Vainberg,Alexandra Blatt,Yael Danin-Poleg,Katya Gershovich,Edmond Sabo,Alex Nevelsky,Shahar Daniel,Aviva Dahan,Oren Ziv,Rishu Dheer,Maria T. Abreu,Omry Koren,Yechezkel Kashi,Yehuda Chowers +13 more
TL;DR: It is demonstrated that rectal radiation induces dysbiosis, which transmits radiation and inflammatory susceptibility and provide evidence that microbial-induced radiation tissue damage is at least in part mediated by IL-1β.
Journal ArticleDOI
Antidepressants affect gut microbiota and Ruminococcus flavefaciens is able to abolish their effects on depressive-like behavior
TL;DR: It is demonstrated that various types of antidepressants alter gut microbiota composition, and further implicate a role for R. flavefaciens in alleviating depressive-like behavior, and a mechanism for microbial regulation of antidepressant treatment efficiency is suggested.
Journal ArticleDOI
Type 2 Diabetes and Congenital Hyperinsulinism Cause DNA Double-Strand Breaks and p53 Activity in β Cells
Sharona Tornovsky-Babeay,Daniela Dadon,Oren Ziv,Elhanan Tzipilevich,Tehila Kadosh,Rachel Schyr-Ben Haroush,Ayat Hija,Miri Stolovich-Rain,J Furth-Lavi,Zvi Granot,Shay Porat,Louis H. Philipson,Kevan C. Herold,Tricia R. Bhatti,Charles A. Stanley,Frances M. Ashcroft,Peter In 'T Veld,Ann Saada,Mark A. Magnuson,Benjamin Glaser,Yuval Dor +20 more
TL;DR: It is shown that genetic activation of β cell glucokinase, initially triggering replication, causes apoptosis associated with DNA double-strand breaks and activation of the tumor suppressor p53, and ATP-sensitive potassium channels (KATP channels) and calcineurin mediate this toxic effect.
Journal ArticleDOI
Dysbiosis of microbiome and probiotic treatment in a genetic model of autism spectrum disorders.
Laure Tabouy,Dimitry Getselter,Oren Ziv,Marcela Karpuj,Timothée Tabouy,Iva Lukic,Rasha Maayouf,Nir Werbner,Hila Ben-Amram,Meital Nuriel-Ohayon,Omry Koren,Evan Elliott +11 more
TL;DR: This study identifies bacterial species that are sensitive to an autism-related mutation, and further suggests a therapeutic potential for probiotic treatment.
