Polymorphisms in the interleukin-4 receptor chain (IL-4R) have been linked to asthma incidence and severity, but a causal relationship has remained uncertain. In particular, a glutamine to arginine substitution at position 576 (Q576R) of IL-4R has been associated with severe asthma, especially in African Americans. We show that mice carrying the Q576R polymorphism exhibited intense allergen-induced airway inflammation and remodeling. The Q576R polymorphism did not affect proximal signal transducer and activator of transcription (STAT) 6 activation, but synergized with STAT6 in a gene target and tissue-specific manner to mediate heightened expression of a subset of IL-4 and IL-13responsive genes involved in allergic inflammation. Our findings indicate that the Q576R polymorphism directly promotes asthma in carrier populations by selectively augmenting IL-4Rdependent signaling.

View SamplesWe generated h-hepatocyte chimeric mice with livers that were predominantly repopulated with h-hepatocytes in a h-growth hormone (GH)-deficient state. Using microarray profiles, comparison between h-hepatocytes from h-GH-treated and untreated mice identified 14 GH-up-regulated and four GH-down-regulated genes, including IGF-1, SOCS2, NNMT, IGFLS, P4AH1, SLC16A1, and SRD5A1, and FADS1 and AKR1B10, respectively.

View SamplesHere, the effects of non-thermal low intensity pulsed ultrasound (LIPUS) on the gene expression in human lymphoma U937 cells were investigated using by an Affymetrix GeneChip system. Six hours after LIPUS treatment (0.3 W/cm2 for 1 min), apoptosis (143.8%, meanSD) with minimal cell lysis was observed. At 3 h post-treatment, LIPUS down-regulated 193 genes and up-regulated 201 genes by >1.5-fold.

Artificially induced epithelial-mesenchymal transition in surgical subjects: its implications in clinical and basic cancer research.

View SamplesSurgical samples have long been used as important subjects for cancer research. In accordance with an increase of neoadjuvant therapy, biopsy samples have recently become imperative for cancer transcriptome. On the other hand, both biopsy and surgical samples are available for expression profiling for predicting clinical outcome by adjuvant therapy; however, it is still unclear whether surgical sample expression profiles are useful for the prediction by the use of biopsy samples because little has been done about comparative gene expression profiling between the two kinds of samples.
