T4Seeker: a hybrid model for type IV secretion effectors identification

open access: yesBMC Biology
Background The type IV secretion system is widely present in various bacteria, such as Salmonella, Escherichia coli, and Helicobacter pylori. These bacteria use the type IV secretion system to secrete type IV secretion effectors, infect host cells, and ...

Identification of protein secretion systems and novel secreted proteins in Rhizobium leguminosarum bv. viciae

open access: yesBMC Genomics, 2008
Background Proteins secreted by bacteria play an important role in infection of eukaryotic hosts. Rhizobia infect the roots of leguminous plants and establish a mutually beneficial symbiosis.

The VirE2 protein of Agrobacterium tumefaciens: the Yin and Yang of T-DNA transfer [PDF]

open access: yes, 2017
Agrobacterium tumefaciens has evolved a unique mechanism to solve the problem of transferring DNA across five bilayers; the inner and outer membranes of the bacterium, the plasma membrane of the plant cell and the double membrane formed by the nuclear ...

BIOGENESIS, ARCHITECTURE, AND FUNCTION OF BACTERIAL TYPE IV SECRETION SYSTEMS [PDF]

open access: yesAnnual Review of Microbiology, 2005
Type IV secretion (T4S) systems are ancestrally related to bacterial conjugation machines. These systems assemble as a translocation channel, and often also as a surface filament or protein adhesin, at the envelopes of Gram-negative and Gram-positive bacteria.

Targeting p38α in cancer: challenges, opportunities, and emerging strategies

open access: yesMolecular Oncology, EarlyView.
p38α normally regulates cellular stress responses and homeostasis and suppresses malignant transformation. In cancer, however, p38α is co‐opted to drive context‐dependent proliferation and dissemination. p38α also supports key functions in cells of the tumor microenvironment, including fibroblasts, myeloid cells, and T lymphocytes.

Type IV Secretion System Is Not Involved in Infection Process in Citrus

open access: yesInternational Journal of Microbiology, 2014
The type IV secretion system (T4SS) is used by Gram-negative bacteria to translocate protein and DNA substrates across the cell envelope and into target cells. Xanthomonas citri subsp.

Conjugative type IV secretion systems in Gram-positive bacteria

open access: yesPlasmid, 2013
Bacterial conjugation presents the most important means to spread antibiotic resistance and virulence factors among closely and distantly related bacteria. Conjugative plasmids are the mobile genetic elements mainly responsible for this task. All the genetic information required for the horizontal transmission is encoded on the conjugative plasmids ...

Phylogenomics Reveals a DiverseRickettsialesType IV Secretion System [PDF]

open access: yesInfection and Immunity, 2010
ABSTRACTWith an obligate intracellular lifestyle,Alphaproteobacteriaof the orderRickettsialeshave inextricably coevolved with their various eukaryotic hosts, resulting in small, reductive genomes and strict dependency on host resources. Unsurprisingly, large portions ofRickettsialesgenomes encode proteins involved in transport and secretion.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

open access: yesMolecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...
