The spatial and temporal organization of T cell signaling molecules is increasingly accepted as a crucial step in controlling T cell activation. CD222, also known as the cation-independent mannose 6-phosphate/insulin-like growth factor 2 receptor, is the central component of endosomal transport pathways. In this study, we show that CD222 is a key regulator of the early T cell signaling cascade....
Expression of the Air ncRNA is necessary to silence multiple genes in cis in the imprinted Igf2r cluster. However, its mode of action is unknown. Here, we characterize co- and post-transcriptional features of Air that identify it as a new member of the class of nuclear regulatory RNAs. We show that Air is transcribed from a DNA methylation-sensitive promoter by RNA polymerase II (RNAPII). Howev...
We aimed to find clinically relevant gene activities ruled by the signal transducer and activator of transcription 3 (STAT3) proteins in an ER(-) breast cancer population via network approach. STAT3 is negatively associated with both lymph nodal category and stage. MYC is a component of STAT3 network. MYC and STAT3 may co-regulate gene expressions for Warburg effect, stem cell like phenotype, c...
A number of large noncoding RNAs (ncRNAs) epigenetically silence genes through unknown mechanisms. The Air ncRNA is imprinted--monoallelically expressed from the paternal allele. Air is required for allele-specific silencing of the cis-linked Slc22a3, Slc22a2, and Igf2r genes in mouse placenta. We show that Air interacts with the Slc22a3 promoter chromatin and the H3K9 histone methyltransferase...
The aberrantly expressed signal transducer and activator of transcription 3 (STAT3) predicts poor prognosis, primarily in estrogen receptor positive (ER(+)) breast cancers. Activated STAT3 is overexpressed in luminal A subtype cells. The mechanisms contributing to the prognosis and/or subtype relevant features of STAT3 in ER(+) breast cancers are through multiple interacting regulatory pathways...
When it escapes early detection, malignant melanoma becomes a highly lethal and treatment-refractory cancer. Melastatin is greatly downregulated in metastatic melanomas and is widely believed to function as a melanoma tumor suppressor. Here we report that tumor suppressive activity is not mediated by melastatin but instead by a microRNA (miR-211) hosted within an intron of melastatin. Increasin...
Article history: Received 13 August 2009 Received in revised form 21 July 2010 Accepted 5 August 2010 In order to test the hypothesis that expression levels of insulin-like growth factor system is altered in piglets with intrauterine growth restriction (IUGR), the present study was conducted to compare the expression levels of IGF-I, IGF-II, IGFR1, IGFR2 and IGFBP5 in m. longissimus, liver and ...
