BACKGROUND Matrix metalloproteinase-9 is a member of the MMP family, which is overexpressed in some solid tumors and is thought to enhance tumor invasion and metastasis ability. The present study aims to examine MMP-9 expression in human colorectal cancer and to determine its association with clinicopathological characteristics and prognosis. METHODS(More)
Wounds that fail to heal in a timely manner, for example, diabetic foot ulcers, pose a health, economic, and social problem worldwide. For decades, conventional wisdom has pointed to growth factors as the main driving force of wound healing; thus, growth factors have become the center of therapeutic developments. To date, becaplermin (recombinant human(More)
Deregulated accumulation of hypoxia-inducible factor-1α (HIF-1α) is a hallmark of many solid tumors. Directly targeting HIF-1α for therapeutics is challenging. Our finding that HIF-1α regulates secretion of heat shock protein-90α (Hsp90α) for cell migration raises the exciting possibility that targeting the secreted Hsp90α from HIF-1α-positive tumors has a(More)
MicroRNAs are noncoding RNAs that regulate multiple cellular processes during cancer progression. Among various microRNAs, MiR-630 has recently been identified to be implicated in many critical processes in human malignancies. We aimed to investigate the significance and prognostic value of miR-630 in human gastric cancer. Gastric cancer and adjacent normal(More)
Heat shock protein 90 (Hsp90) has been historically known as an abundant and intracellular ATP-driven chaperone with more than 100 target proteins that often play critical roles in various branches of the signaling networks for control of cell metabolism, survival, growth and differentiation. In many cancers, Hsp90 is either over-expressed or over-activated(More)
