Adult stem cells have the ability to self-renew and to generate specialized cells. Self-renewal is dependent on extrinsic niche factors but few of those signals have been identified. We show that adult mammary glands contain a Wnt-responsive cell population that is enriched for stem cells. In cell culture experiments, exposure to purified Wnt protein clonally expands mammary stem cells for many generations and maintains their ability to generate functional glands in transplantation assays. We propose here that Wnt3A treated mammary stem cells retain their stemness through the regulation of its downstream target genes.

View SamplesWe generated three kinds of genetically identical mouse reprogrammed cells: induced pluripotent stem cells (iPSCs), nuclear transfer embryonic stem cells (ntESCs) and iPSC-nt-ESCs that are established after successively reprogramming of iPSCs by nuclear transfer (NT). NtESCs show better developmental potential than iPSCs, whereas iPSC-nt-ESCs display worse developmental potential than iPSCs.

View SamplesNEDD9 is important for lung cancer metastasis. However, the detailed mechanism remains elusive. Using the microarray data generated with human lung cancer cell lines with either NEDD9 overexpression or NEDD9 knockdown, we plan to idnetify important signal pathways regulated by NEDD9. This may explain how NEDD9 excutes its function in lung cancer.
NEDD9 promotes lung cancer metastasis through epithelial-mesenchymal transition.

View SamplesThe intestinal epithelial barrier plays a critical role in the mucosal immunity. However, it remains largely unknown how the epithelial barrier is maintained after damage. Here we show that FGF2 synergizes with IL-17A to induce genes for repairing of damaged epithelium. Deficiency of FGF2 or IL-17A resulted in impaired epithelial proliferation, increased pro-inflammatory microbiota outgrowth, and consequently worse pathology in a DSS-induced colitis model.
Growth Factor FGF2 Cooperates with Interleukin-17 to Repair Intestinal Epithelial Damage.

View SamplesPluripotency-associated transcription factor Foxd3 is required for maintaining pluripotent cells. However, the molecular mechanisms underlying its function are largely unknown. Here, we report that Foxd3 maintains the ESC identity through counteracting differentiation induction of Calcienurin-NFAT signaling.
Foxd3 suppresses NFAT-mediated differentiation to maintain self-renewal of embryonic stem cells.

View SamplesNeuro-2a cells were infected with ZIKV (MOI = 0.5) for 48 h and total RNA was extracted and purified using TRI Reagent and RNeasy Mini kit (Qiagen). RNA-seq was performed at the Molecular and Genomics Core Facility of the University of Mississippi Medical Center. Differential expression analysis between mock and ZIKV infected cells was done using Tophat and cuffdiff programs from the tuxedo suite.

View SamplesThe young panicles 2 cm length were used for expression analysis in well watered control and drought stressed treatment. The panicle samples from biological replicates of six rice varieties were obtained in three independent experiments. The expression profiles were generated using Affymetrix rice genome arrays.
