Pancreatic Cancer and MicroRNAs

Hwang JH

MicroRNAs (miRNAs) are recently discovered non-coding small RNAs that play a role as regulators of genetic expressions in eukaryotic cells. It comprises about 20 nucleotides, which contains seed sequence to...

Emodin prevents intima thickness via Wnt4/Dvl-1/beta-catenin signaling pathway mediated by miR-126 in balloon-injured carotid artery rats

Hua JY, He YZ, Xu Y, Jiang XH, Ye W, Pan ZM

Neointimal proliferation after vascular injury is a key mechanism of restenosis, a major cause of percutaneous transluminal angioplasty failure and artery bypass occlusion. Emodin, an anthraquinone with multiple physiological activities,...

Expression of MicroRNA in Host Cells Infected with Helicobacter pylori

Chung JW, Jeong SH, Lee SM, Pak JH, Lee GH, Jeong JY, Kim JH

BACKGROUND/AIMS: MicroRNAs (miRNAs) regulate gene expression. We assess miRNA regulation by Helicobacter pylori infection and elucidate their role in H. pylori-infected gastric epithelial cells. METHODS: The relationship between miRNA expression and...

miR-27 regulates mitochondrial networks by directly targeting the mitochondrial fission factor

Tak H, Kim J, Jayabalan , Lee H, Kang H, Cho DH, Ohn T, Nam SW, Kim W, Lee EK

Mitochondrial morphology is dynamically regulated by forming small, fragmented units or interconnected networks, and this is a pivotal process that is used to maintain mitochondrial homeostasis. Although dysregulation of mitochondrial...

MicroRNA-200c as a Prognostic Biomarker for Pancreatic Cancer

Paik WH, Song BJ, Kim HW, Kim HR, Hwang JH

BACKGROUND/AIMS: MicroRNA (miRNA) regulates messenger RNA stability and translation. In cancer biology, miRNA affects the growth and metastasis of cancer cells by controlling epithelial-mesenchymal transition (EMT). MiR-200 family (200a/200b/200c/141) and...
