Identification and pathogenomic analysis of an Escherichia coli strain producing a novel Shiga toxin 2 subtype

Scientific Reports, 2018
Shiga toxin (Stx) is the key virulent factor in Shiga toxin-producing Escherichia coli (STEC). To date, three Stx1 subtypes and seven Stx2 subtypes have been described in E. coli, which differed in receptor preference and toxin potency.

Simple oxidation of pyrimidinylhydrazones to triazolopyrimidines and their inhibition of Shiga toxin trafficking [PDF]

, 2010
The oxidative cyclisation of a range of benzothieno[2,3-d]pyrimidine hydrazones (7a–j) to the 1,2,4-triazolo[4,3-c]pyrimidines (8a–j) catalysed by lithium iodide or to the 1,2,4-triazolo[1,5-c]pyrimidines (10a–j) with sodium carbonate is presented.

Antibiotic‐resistant Shiga toxin‐producing Escherichia coli: An overview of prevalence and intervention strategies

Zoonoses and Public Health, 2018
Shiga toxin‐producing Escherichia coli (STEC) are foodborne pathogens that can cause severe diseases, including bloody diarrhoea and kidney failure, in humans, while remaining harmless to its primary reservoir hosts, cattle.

A Human Kidney Tubuloid Model of Repeated Cisplatin‐Induced Cellular Senescence and Fibrosis for Drug Screening

Advanced Healthcare Materials, EarlyView.
Replicating aging and senescence‐related pathophysiological responses in kidney organoids remains a significant challenge. Human adult renal tubular organoid, tubuloids, are successfully developed recapitulating cellular senescence that is the central pathophysiological mechanism of chronic kidney disease (CKD).

Replication of plasmids derived from Shiga toxinconverting bacteriophages in starved Escherichia coli [PDF]

, 2011
The pathogenicity of Shiga toxin-producing Escherichia coli (STEC) depends on the expression of stx genes that are located on lambdoid prophages. Effective toxin production occurs only after prophage induction, and one may presume that replication of the

Shiga toxin binds to activated platelets [PDF]

Journal of Thrombosis and Haemostasis, 2004
Hemolytic uremic syndrome (HUS) is associated with acute renal failure in children and can be caused by Shiga toxin (Stx)-producing Escherichia coli. Thrombocytopenia and formation of renal thrombi are characteristic of HUS, suggesting that platelet activation is involved in its pathogenesis. However, whether Shiga toxin directly activates platelets is

Folic Acid‐Modified Ginger‐Derived Exosome‐Like Nanoparticles Co‐Delivering Sunitinib Suppress Renal Cell Carcinoma via PI3K‐Akt Pathway Inhibition, P‐gp Downregulation, and Macrophage Reprogramming

Advanced Science, EarlyView.
FPD‐GELNs co‐deliver Su and bioactive components. This active‐passive dual‐targeting strategy suppresses the progression of RCC through the following mechanisms: 1) inhibition of the PI3K‐Akt signaling pathway; 2) downregulation of ABCB1/P‐gp to enhance the chemosensitivity of RCC to Su; and 3) reprogramming of macrophages toward M1 polarization and ...
