The transcriptome changes of the ileal mucosa in suckling piglets during early postnatal life were analysed to contribute to the knowledge of a pigs gut development. In addition, the ileal transcriptome of suckling piglets was compared with that of age-matched weaned piglets (weaned at the age of 21 days) to elucidate the effect of weaning on the developing gut.

View SamplesWe analyzed the effects of cellular context on the function of the synovial sarcoma-specific fusion protein, SS18-SSX, using human pluripotent stem cells containing the drug-inducible SS18-SSX gene. To investigate the cell-type-dependent effecfts of SS18-SSX, we performed gene expression profiling experiments.

View SamplesLactic acid bacteria confer a variety of health benefits. Here we investigate the mechanisms by which Lactobacillus brevis KB290 enhances cell-mediated cytotoxic activity. We fed a diet containing KB290 (3 10^9 colony-forming units/g) , or potato starch, to 9-week-old female BALB/c mice for 1, 4, 7, or 14 days and examined the cytotoxic activity of splenocytes was measured. RNA was extracted from the spleen and analyzed for gene expression by DNA microarray.

View SamplesPersistent colonization of the gastric mucosa by Helicobacter pylori (Hp) elicits chronic inflammation and aberrant epithelial cell proliferation, which increases the risk of gastric cancer. We examined the ability of microRNAs to modulate gastric cell proliferation in response to persistent Hp infection and found that epigenetic silencing of miR-210 plays a key role in gastric disease progression. Importantly, DNA methylation of the miR-210 gene was increased in Hp-positive human gastric biopsies as compared to Hp-negative controls. Moreover silencing of miR-210 in gastric epithelial cells promoted proliferation. We identified STMN1 and DIMT1 as miR-210 target genes and demonstrated that inhibition of miR-210 expression augmented cell proliferation by activating STMN1 and DIMT1. Together, our results highlight inflammation-induced epigenetic silencing of miR-210 as a mechanism of induction of chronic gastric diseases, including cancer, during Hp infection.

BES1 and BZR1 Redundantly Promote Phloem and Xylem Differentiation.
Specimen part, Treatment, Time
View SamplesXylem consists of three types of cells: vessel cells, also referred to as tracheary elements (TEs), parenchyma cells, and fiber cells. TE differentiation includes two essential processes, programmed cell death (PCD) and secondary cell wall formation. These two processes are tightly coupled. However, little is known about the molecular mechanism of their gene regulation. Here, we show that VASCULAR-RELATED NAC-DOMAIN 6 (VND6), a master regulator of TEs, regulates these processes in a coordinated manner. We first identified specific genes downstream of VND6 by comparing them with those of SECONDARY WALL-ASSOCIATES NAC DOMAIN PROTEIN1 (SND1), a master regulator of xylem fiber cells, with transformed suspension culture cells in microarray experiments.
Arabidopsis VASCULAR-RELATED NAC-DOMAIN6 directly regulates the genes that govern programmed cell death and secondary wall formation during xylem differentiation.
