Acute duodenal obstruction after hemorrhaging of a duodenal duplication cyst

Duodenal duplication cysts are relatively rare congenital anomalies that occur most often in infants and children. We report a case of a 13-year-old boy who presented with duodenal obstruction caused by bleeding of a duodenal duplication cyst. Operative findings and hispathological examination confirmed the diagnosis. We treated him with subtotal excision of the duodenal duplication cyst and mucosal stripping and ablation of the remaining mucosa

miR-34a-5p might have an important role for inducing apoptosis by down-regulation of SNAI1 in apigenin-treated lung cancer cells

Apigenin is a flavonoid with antioxidant and anticancer effects. It has been reported that apigenin inhibits proliferation, migration, and invasion and induces apoptosis in cultured lung cancer cells. However, there is little information on the involvement of microRNAs (miRNAs) in its effects. miRNA microarray analysis and polymerase-chain-reaction analysis of miRNAs revealed that treatment of human lung cancer A549 cells with apigenin up-regulated the level of miR-34a-5p. Furthermore, mRNA microarray analysis and the results of three microRNA target prediction tools showed that Snail Family Transcriptional Repressor 1 (SNAI1), which inhibits the induction of apoptosis, had its mRNA expression down-regulated in A549 cells treated with apigenin. Our findings suggest that apigenin might induce apoptosis by down-regulation of SNAI1 through up-regulation of miR-34a-5p in A549 cells
