Stimulation of pro-opiomelanocortin gene expression by glucocorticoids in the denervated rat intermediate pituitary gland.

abstract：AIM:To extensively explore microRNA expression profiles in lung carcinoids in correlation with clinical and pathological features. METHODS:A PCR-based array was employed in the screening phase to analyze 752 microRNAs in a discovery set of 12 lung carcinoids, including 6 typical (3 with lymph node metastasis) and 6 at...
