Virtually all cases of mantle cell lymphoma (MCL) carry the t(11;14)(q13;q32) translocation, leading to the juxtaposition of the CCND1/CYCLIND1 gene to the immunoglobulin heavy chain (IGH) joining region, resulting in cyclin D1 mRNA and protein overexpression.1-3 The existence of “true” MCL negative for cyclin D1 has been controversial but was recently substantiated by gene expression profiling...

KLF5 is a transcription factor. Many KLF5 target genes, such as PDGFa, PPARg, NFkB, cyclinD1, KLF4, and TCR, have been identified in different cell models. KLF5 regulates cell proliferation, cell cycle, apoptosis, and differentiation. KLF5 is an important transcription factor for cardiovascular remodeling and tumor angiogenesis. KLF5 is essential for mouse embryo development. Additionally, KLF5...

Neural stem cells (NSCs) in the adult mammalian brain generate neurons and glia throughout life. However, the physiological role of adult neurogenesis and the use of NSCs for therapy are highly controversial. One factor hampering the study and manipulation of neurogenesis is that NSCs, like most adult somatic stem cells, are difficult to expand and their switch to differentiation is hard to con...

Cancer stem cells have been found to play important roles in carcinoma. Although thy-1 has been identified as a potential stem cell marker of liver cancer, whether the Wnt/β-catenin signaling pathway plays an important role in regulating hepatocarcinoma proliferation and apoptosis mediated by thy-1 remains unknown. Our results showed that high thy-1 expression caused hepG2 cells transfected wit...

OBJECTIVES Glucose fluctuations are both strong predictor of diabetic complications and crucial factor for beta cell damages. Here we investigated the effect of intermittent high glucose (IHG) on both cell apoptosis and proliferation activity in INS-1 cells and the potential mechanisms. METHODS Cells were treated with normal glucose (5.5 mmol/L), constant high glucose (CHG) (25 mmol/L), and I...

Colorectal cancer (CRC) is the third most common cancer in the world. Oplopanax elatus is widely used in traditional medicine. However, little is known about its pharmacological effects and bioactive compounds. We evaluated the effects of the polyyne-enriched extract from O. elatus (PEO) on the progression of colon carcinogenesis in ApcMin/+ mice. In addition, these effects were also investigat...
