TLR4 deficiency attenuates kidney injury after ischemic reperfusion as measured by both renal function and morphology. To better understand the role of TLR4 during the acute kidney injury, we used DNA microarray to identify genes that were differentially expressed on kidneys in wildtype B10 mice and TLR4 null mice during the early stage of injury.
Endothelial pentraxin 3 contributes to murine ischemic acute kidney injury.

View SamplesPreviously, we found that LZTFL1 is down-regulated in epithelial tumors including lung cancer and functions as a tumor suppressor in gastric cancers. However, the functional role of LZTFL1 in lung oncogenesis is undefined. We show here that downregulation of LZTFL1 expression in non-small cell lung cancer is associated with recurrence and poor survival, while re-expression of LZTFL1 in lung tumor cells inhibited extravasation/colonization of circulating tumor cells to the lung and inhibited tumor growth in vivo. Mechanistically, we found that LZTFL1 is expressed in ciliated human bronchial epithelial cells (HBECs) and its expression correlates with HBEC differentiation. LZTFL1 inhibits TGF-activated MAPK and hedgehog signaling. Alteration of intracellular levels of LZTFL1 resulted in changes of expression of genes associated with epithelial-to mesenchymal transition (EMT). We conclude that LZTFL1 inhibit lung tumorigenesis, possibly by maintaining epithelial cell differentiation and/or inhibition of signalings that lead to EMT, and suggest that reactivation of LZTFL1 expression in tumor cells may be a novel lung cancer therapeutic approach.
