Recent studies have indicated that side population (SP) cells, which are an enriched source of cancer stem cells (CSCs), drive and maintain many types of human malignancies. SP cells have distinguishing biological characteristics and are thought to contribute to metastasis, therapy resistance, and tumor recurrence. In the present study, the miRNA expression(More)
Endogenous caldesmon kinase activity in sheep aorta smooth muscle was purified and characterized. The enzyme was identified as a proteolytic fragment of protein kinase C by cross-reactivity with anti-protein kinase C antibodies, autophosphorylation, substrate specificity and the primary structure of the sites of phosphorylation on caldesmon. The enzyme(More)
