(Submitter supplied) Leukemia inhibitory factor (LIF) is amongst the IL-6 family cytokines expressed in the lungs during pneumonia. However, the function of endogenous LIF during pneumonia has never been explored. The purpose of this study was to determine the transcriptional response to pneumonia in the lungs and whether or how this response is influenced by LIF. Mice received intratracheal instillations of vehicle (PBS) or Escherichia coli (10^6 CFU). more...

(Submitter supplied) C57BL/6 mice were intratracheally challenged for 24 hours with saline or E. coli (1 x 10^6 CFU) with or without LIF neutralization. Left lobes were collected and digested into single-cell suspensions for FACS. Equal ratios of CD45+ (leukocytes), CD45-EpCAM+ (epithelium), and CD45-EpCAM- (other) cells were pooled from a mouse undergoing each condition.

(Submitter supplied) During bacterial pneumonia, alveolar epithelial cells are critical for maintaining gas exchange and providing antimicrobial as well as pro-immune properties. We previously demonstrated that leukemia inhibitory factor (LIF), an IL-6 family cytokine, is produced by type II alveolar epithelial cells (ATII) and is critical for tissue protection during bacterial pneumonia. However, the target cells and mechanisms of LIF-mediated protection remain unknown. more...

(Submitter supplied) Leukemia inhibitory factor (LIF) is a cytoprotective cytokine that reduces lung injury during pneumonia. The purpose of this study was to determine the influence of LIF on pneumonia-induced gene changes in lung epithelium. Mice received intratracheal instillations of vehicle (PBS) or Escherichia coli (10^6 CFU). Control IgG or anti-LIF specific IgG was included in the instillate. 6 hours after the challenge, lung epithelial cells (EpCAM+/CD45-) were sorted from enzymatic lung digests and used for RNA isolation and microarray analysis.

(Submitter supplied) Cachexia is an exacerbating event in many types of cancer that is strongly associated with a poor prognosis. We have identified cytokine, signaling and transcription factors that are required for cachexia in the mouse C26 colon carcinoma model of cancer. C2C12 myotubes treated with conditioned medium from C26 cancer cells induced atrophy and activated a STAT-dependent reporter gene but not reporter genes dependent on SMAD, FOXO, C/EBP, NF-ĸB, or AP-1. more...

(Submitter supplied) T helper 17 (Th17) cell differentiation triggered by interleukin-6 (IL-6) via STAT3 activation promotes inflammation in inflammatory bowel disease (IBD) patients. However, leukemia inhibitory factor (LIF), an IL-6 family cytokine, restricts inflammation by blocking Th17 cell differentiation via an unknown mechanism. Here, we report that microbiota dysregulation promotes LIF secretion by intestinal epithelial cells (IECs) in a mouse colitis model. more...

(Submitter supplied) We report that microbiota dysregulation promotes LIF secretion by intestinal epithelial cells (IECs) in a mouse colitis model. LIF greatly activates STAT4 phosphorylation on multiple SPXX elements within the C-terminal transcription regulation domain. STAT4 and STAT3 act reciprocally on both canonical cis-inducible elements (SIEs) and noncanonical “AGG” elements at different loci. In lamina propria lymphocytes (LPLs), STAT4 activation by LIF blocks STAT3-dependent Il-17a/Il-17f promoter activation, whereas in IECs, LIF bypasses the extraordinarily low level of STAT4 to induce YAP gene expression via STAT3 activation. more...

(Submitter supplied) While the hypothalamo-pituitary-adrenal axis (HPA) activates a general stress response by increasing glucocorticoid (Gc) synthesis, biological stress resulting from infections triggers the inflammatory response through production of cytokines. The pituitary gland integrates some of these signals by responding to the pro-inflammatory cytokines IL6 and LIF and to a negative Gc feedback loop. The present work used whole-genome approaches to define the LIF/STAT3 regulatory network and to delineate cross-talk between this pathway and Gc action. more...

(Submitter supplied) The TET family of FE(II) and 2-oxoglutarate-dependent enzymes (Tet1/2/3) promote DNA demethylation by converting 5-methylcytosine to 5-hydroxymethylcytosine (5hmC), which they further oxidize into 5-formylcytosine and 5-carboxylcytosine. Tet1 is robustly expressed in mouse embryonic stem cells (mESCs) and has been implicated in mESC maintenance. Here we demonstrate that, unlike genetic deletion, RNAi-mediated depletion of Tet1 in mESCs led to a significant reduction in 5hmC and loss of mESC identity. more...

(Submitter supplied) In this study, we further verified the role of LIF by looking at gene expressions in morula stage embryos through DNA microarray. Our results showed that LIF knockdown affected 373 gene expressions, and after LIF supplementation we found that the epidermal growth factor (EGF) is most affected by LIF expression. In order to observe the correlation between LIF and EGF, the LIF knockdown embryos were supplemented with various growth factors including LIF, EGF, GM-CSF, TGF, and IGF II. more...

(Submitter supplied) Systemic duress such as that elicited by sepsis, burns or trauma predispose patients to nosocomial pneumonia, demanding a better understanding of host pathways influencing this connection. These systemic challenges are also capable of triggering the hepatic acute phase response (APR), an event that we have previously demonstrated as essential for limiting susceptibility to secondary lung infections. more...

(Submitter supplied) Infectious pneumonias exact an unacceptable mortality burden worldwide. Efforts to protect populations from pneumonia have historically focused on antibiotic development and vaccine-enhanced adaptive immunity. However, we have recently reported that the lungs’ innate defenses can be therapeutically induced by inhalation of a bacterial lysate that protects mice against otherwise lethal pneumonia. Here, we tested in mice the hypothesis that Toll-like receptors (TLRs) are required for this antimicrobial phenomenon, and found that resistance could not be induced in the absence of the TLR signaling adaptor protein MyD88. more...
