miR-34a is strongly induced upon TPA-induced megakaryocyte differentiation of K562 cells. To investigate the gene networks regulated by this miRNA during the process of differentiation we performed gene microarray analysis in K562 cells overexpressing miR-34a or a control sequence.
miR-34a contributes to megakaryocytic differentiation of K562 cells independently of p53.

View SamplesIn this study, investigators recruited the largest reported cohort of tolerant kidney transplant recipients who maintained their graft after ceasing to take their immunosuppression drug, and compared this cohort to subjects with stable allograft function while on immunosuppression and healthy non transplated, controls. Using gene expression studies, they identified genetic markers that are strong candidates for predicting kidney transplant candidates who may benefit from minimization or withdrawl of immunosuppression.

View SamplesCardiomyocyte-like cells can be reprogrammed from somatic fibroblasts by combinations of genes, providing a new avenue for cardiac regenerative therapy. Here we show that functional cardiomyocytes can be rapidly and efficiently generated from human fibroblasts by specific combination small molecules. Microarray analysis has been used to compare the expression profile of cardiomyocyte-like cells derived from human foreskin and lung fibroblasts, and human ES cell-derived cardiomyocytes.
