103por Gada, Kirin D., Xu, Yu, Winn, Brenda T., Masotti, Meghan, Kawano, Takeharu, Vaananen, Heikki, Plant, Leigh D.“…Here, we present a protocol for optogenetic dephosphorylation of the phosphoinositide PI(4,5)P(2) at the plasma membrane of Xenopus laevis oocytes. We first describe the co-injection of oocytes with cRNAs encoding (1) a light-activated PI(4,5)P(2) 5-phosphatase fusion protein, (2) its dimerization partner fused to the plasma membrane, and (3) the potassium channel reporter for PI(4,5)P(2) dephosphorylation. …”

Xenopus laevis is a widespread invasive amphibian species in Chile. …”

110Publicado 1988“…By scanning electron microscopy, we have observed that a 20-min heat shock at 37 degrees C, although not lethal, causes extensive damage to the epidermis of 30-h and 2-d (post-fertilization) Xenopus laevis larvae. The primary effects of heat shock are the apical swelling of the epidermal cells, giving the epidermis a "cobblestone" appearance, and the selective shedding of the ciliated cells. …”

METHODS: A morpholino targeted to Psf2 mRNA was designed to knockdown Psf2 translation and was injected into specific embryonic cells during early cleavage stages in the frog, Xenopus laevis. …”

Morpholino oligonucleotide mediated knock-down approaches in anterior neural tissue revealed that interference with either Sox4 or Sox11 function affects eye development. …”
