Project description:We have employed Arraystar Mouse LncRNA Microarray V3.0 as a discovery platform to identify LncRNA and mRNA profile between prenatal and adult mouse liver tissues. Mouse E18 and 2-month old liver total RNA were commercially purchased.
Project description:Prenatal exposure to infectious or inflammatory insults can increase the risk of neuropsychiatric disorders with neurodevelopmental components, including schizophrenia and autism. The molecular processes underlying this pathological association are only partially understood. Here, we implemented an unbiased genome-wide transcriptional profiling of the prefrontal cortex of mice exposed to prenatal infection on GD17 compared to control subjects in order to elucidate the long term molecular signature of late prenatal infection. We used microarray analysis to investigate the long lasting gene expression changes in a well-established mouse model that is based on maternal treatment with the viral mimic poly(I:C) during pregnancy

Offspring were subjected to cognitive and behavioral testing in adulthood, and then whole genome gene expression analysis with Affymetrix Microarray and subsequent q-PCR validation were performed on the prefrontal Cortex.

Project description:Prenatal cadmium (Cd) exposure leads to immunotoxic phenotypes in the offspring. Long non-coding RNAs (lncRNAs) are integral to T cell regulation. Here, we identified genes and pathways altered in CD4+ T cell by prenatal Cd exposure. We investigated the role of long non-coding RNA small nucleolar RNA hostgene 7 (lncSnhg7) in T cell proliferation: LncSnhg7 expression increases in CD4+ T cells following stimulation with anti-CD3/CD28 beads. LngSnhg7 and a downstream protein, GALNT7, are upregulated in T cells from offspring exposed to Cd during gestation. Overexpression of miR-34a, a regulator of lnhcSnhg7 and GALNT7, suppresses GALNT7 protein levels in primary T cells, but not in a mouse T lymphocyte cell line. The T cells isolated from Cd-exposed offspring exhibit increased proliferation after activation in vitro, but Treg suppression and CD4+ T cell apoptosis are not affected by prenatal Cd exposure. In conclusion, prenatal Cd exposure alters the expression of lncRNAs during T cell activation. The induction of lncSnhg7 is enhanced in splenic T cells from Cd offspring resulting in the upregulation of GALNT7 protein and increased proliferation following activation. miR-34a overexpression decreased GALNT7 expression suggesting that the lncSnhg7/miR-34a/GALNT7 is an important pathway in primary CD4+ T cells. These data highlight the need to understand the consequences of environmental exposures on lncRNA functions in non-cancerous cells.
