We have previously established a mouse malignant T-lymphoma CS-21 cell line that preferentially metastasizes to lymph nodes after s.c. inoculation into BALB/c mice. The CS-21 lymphoma cells were grown in vitro in the presence of CA-12 stromal cells isolated from lymph nodes. When CS-21 cells were cultured alone, they underwent apoptotic cell death with DNA fragmentation. In contrast, the cultur...
PURPOSE MicroRNAs are approximately 22 nucleotide noncoding RNA molecules that posttranscriptionally regulate gene expression. The aim of this study was (a) to determine a role of microRNA-21 in esophageal squamous cell carcinoma and (b) to elucidate the regulation of the programmed cell death 4 (PDCD4) gene by microRNA-21. EXPERIMENTAL DESIGN MicroRNA-21 expression was investigated in 20 mat...
This study was conducted to evaluate the effect of 5% and 21% oxygen concentrations on chimeric embryo development. Inner cell mass (ICM) from parthenogenetic activated blastocyst were used produce ES cell-like cells. A pair zona-free tetraploid embryos one clump pESCs at passage 2 3 aggregated granulosa monolayer in such a manner that sandwiched between embryos. The aggregates prepared randoml...
Interleukin- (IL-) 21 is a pleiotropic cytokine that regulates the activity of both innate and specific immunity. Indeed, it costimulates T and natural killer (NK) cell proliferation and function and regulates B cell survival and differentiation and the function of dendritic cells. In addition, IL-21 exerts divergent effects on different lymphoid cell leukemia and lymphomas, as it may support c...
