(Submitter supplied) Alveolar macrophages from never smokers and active smokers were isolated by bronchoalveolar lavage and gene expression was measured. Chronic cigarette smoke exposure, as occurs in smoker's lungs, leads to significant changes in gene expression. Of note, RNA was isolated immediately following bronchoscopy. Alveolar macrophage levels were >95%.

(Submitter supplied) MicroRNAs (miRNAs) are a family of short, noncoding RNAs that regulate translation of mRNAs by mechanisms involving the binding of complementary sequences. The influence of miRNAs on the proteome and cellular events is extensive as they regulate an estimated 60% of the transcriptome and play key roles in differentiation, plasticity, circadian rhythm, immunity, and disease. The post-transcriptional biogenesis of most miRNAs involves a sequential cleavage process mediated by RNase III family enzymes. more...

(Submitter supplied) Biogenesis of canonical microRNAs (miRNAs) involves multiple steps: nuclear processing of primary miRNA (pri-miRNA) by DROSHA, nuclear export of precursor miRNA (pre-miRNA) by Exportin 5 (XPO5), and cytoplasmic processing of pre-miRNA by DICER. To gain a deeper understanding of the contribution of each of these maturation steps, we deleted DROSHA, XPO5, and DICER in the same human cell line, and analyzed their effects on miRNA biogenesis. more...

(Submitter supplied) Background: When exposed to specific stimuli, macrophages exhibit distinct activation programs, M1 and M2 polarization, that define macrophage function as inflammatory/immune effectors or anti-inflammatory/tissue remodeling cells, respectively. Due to their position on the lung epithelial surface, alveolar macrophages (AM) directly interact with environmental stimuli such as cigarette smoke, the major risk factor for the development of chronic obstructive pulmonary disease (COPD). more...

(Submitter supplied) Increased monocyte adhesion to dysfunctional endothelial cells (ECs) orchestrated by chemokines plays an important role in arterial inflammation during atherosclerosis. Endothelial microRNAs (miRNAs) processed by the RNase Dicer1 determine the phenotype of ECs by posttranscriptional regulation of gene expression. However, the impact of endothelial miRNAs on endothelial inflammation and atherosclerosis is currently unclear. more...

(Submitter supplied) MicroRNAs (miRNAs) are small, endogenous, non-protein coding RNAs that are an important means of post-transcriptional gene regulation. Deletion of Dicer, a key miRNA processing enzyme, is embryonic lethal in mice, and tissue-specific Dicer deletion results in developmental defects. Using a conditional knockout model, we generated mice lacking Dicer in the adrenal cortex. These Dicer knockout (KO) mice exhibited perinatal mortality and failure of the adrenal cortex during late gestation between embryonic day 16.5 (E16.5) and E18.5. more...
