The ras oncogene-encoded p21 protein is known to induce cell maturation of Xenopus laevis oocytes and malignant transformation of NIH 3T3 mouse fibroblasts. The pathways involved in oocytes and NIH 3T3 cells appear to be similar to one another. For example, in both cases, the ras p21-induced cellular events involve increased intracellular levels of the second messengers diacylglycerol and inosi...
Wen-Shiun Yueh and Ching-Fong Chang (2000) Morphological changes and competence of maturing oocytes in the protandrous black porgy, Acanthopagrus schlegeli. Zoological Studies 39(2): 114-122. The study objectives aimed to investigate the morphological changes of oocytes during final oocyte maturation and ovulation, and the maturational competence of oocytes to respond to maturation-inducing ste...
Guiducci et al. report on page 1999 that plasmacytoid dendritic cells (PDCs) mount either innate or adaptive immune responses depending on the subcellular localization of foreign DNA. PDCs are very rare in the body (making up less than 1% of the cells in the blood) but are important for antiviral immune responses. Activation of the endosomal receptor TLR9 by viral DNA can induce PDCs either to ...
Articular cartilage maturation is the postnatal development process that adapts joint surfaces to their site-specific biomechanical demands. Maturation involves gross morphological changes that occur through a process of synchronised growth and resorption of cartilage and generally ends at sexual maturity. The inability to induce maturation in biomaterial constructs designed for cartilage repai...
Background: Nowadays, dendritic cells (DC) are used for tumor immunotherapy as they can induce immune responses against tumor cells. In this research, we comprehensively studied the maturation stimulus addition, PHA-activated T-cell (PHA- TCM) conditioned medium, autologous monocyte-conditioned medium (MCM) and TNF-α for their ability to promote uniformly mature dendritic cells that eli...
Natural killer (NK) cells are effector cells of the innate immune system that exert direct cytotoxic functions. Ubiquitously-expressed toll-like receptors (TLRs) have been recognized as one of the major components promoting dendritic cell (DC) maturation, which may induce polarized immune responses beneficial to cancer immunotherapy. TLR-activated NK cells and DCs are prerequisite for robust ac...
