Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Mammalian telomeres are formed by tandem repeats of the TTAGGG sequence, and shorten with each round of cell division in the absence of telomerase. Telomere shortening and dysfunction has been implicated in the pathology of several age-related diseases and premature ageing syndromes. Telomerase is important for telomere length maintenance. Telomerase RNA component, also known as TERC, is a component of telomerase. Terc knockout leads to telomerase deficiency and telomere shortening. Heterozygous telomerase-deficient (Terc+/-) mice were housed and bred for homozygous generation. ESC lines were generated with high efficiency from wild-type (WT, Terc+/+), heterozygous (Het, Terc+/-) and early- to late-generation (G1, G3 and G4) Terc-/- mouse blastocysts. Telomeres were shorter in Terc+/- ES cells than in WT ES cells, and further shortened from G1 to G4 Terc-/- ES cells. We took advantage of ES cell lines with various telomere lengths to investigate roles of telomere length on differentiation capacity of ES cells. We found that telomere length, but not telomerase activity, is required for differentiation of ES cells into epidermis.

Description
Interleukin 7 receptor (IL7R) is a transmembrane receptor which belongs to the type I cytokine receptor family. Recent studies have indicated that the IL7R is involved in the pathogenesis of some neurodegenerative disorders, such as multiple sclerosis. Previously, we found that the retinal neuroregenation was delayed following the targeted knockdown of IL7R, highlighting the potential role of IL7R in the development of nervous system.

Description
Myeloid-derived suppressor cells (MDSCs) have emerged as major regulators of immune responses in cancer and other pathological conditions. At the epigenetic level, lncRNA play an important role in cell differentiation and function. We identify a novel long non-coding RNA (lncRNA) termed as lnc-mdsc in MDSCs, which may tightly control the development of MDSCs.

Lactobacillus NK2 (L.NK2) is a commensal microbe, isolated from the mouse intestinal feces in our lab. To examine the potential role of L. NK2 in the gut immunity, we monocolonized GF mice with L.NK2. And, we conducted a microarray experiment to compare the transcriptomes of GF and L.NK2-colonized mice intestines under the same experimental condition

Description
The Suppressor of cytokine signaling (SOCS) family of negative regulatory proteins are upregulated in response to several cytokines and pathogen-associated molecular patterns (PAMPs), and suppress cellular signaling responses by binding receptor phosphotyrosine residues. Exposure of bone marrow-derived dendritic cells (BMDCs) to 1D8 cells, a murine model of ovarian carcinoma, suppresses their ability to express CD40 and stimulate antigen specific responses in response to PAMPs, and in particular to poly I: C with the upregulated SOCS3 transcript and protein levels. The ectopic expression of SOCS3 in both the macrophage cell line RAW264.7 and BMDCs decreased signaling in response to both poly I:C and IFN. Further, knockdown of SOCS3 transcripts significantly enhanced the responses of RAW264.7 and BMDCs to both poly I: C and IFN. Immunoprecipitation and pull-down studies demonstrate that SOCS3 binds to the IFN receptor TYK2. Since poly I: C triggers autocrine IFN signaling, binding of SOCS3 to TYK2 may thereby suppress the activation of BMDCs by polyI:C and IFN. Thus, elevated levels of SOCS3 in tumor-associated DCs may potentially resist the signals induced by TLR3 ligands and type I interferon to decrease DC activation via binding with IFN receptor TyK2.
