Hermes (Rbpms) is a critical component of RNP complexes that sequester germline RNAs during oogenesis
(MDPI, 2016-03)
The germ cell lineage in Xenopus is specified by the inheritance of germ plasm that assembles within the mitochondrial cloud or Balbiani body in stage I oocytes. Specific RNAs, such as nanos1, localize to the germ plasm. ...
Expression of the Subunits of Protein Kinase CK2 During Oogenesis in Xenopus laevis
(1995)
Northern‐blot analysis of RNAs from different tissues demonstrated that the mRNA for the protein kinase CK2α subunit is very abundant in the ovary of Xenopus laevis. The competitive reverse‐PCR technique has been used to ...
Descripción parcial de la oogénesis de Gastrotheca orophylax (Anura, Hemiphractidae)
(PUCE, 2016)
El proceso en el que se desarrollan los oocitos se denomina oogénesis. Este proceso ha sido descrito detalladamente en Xenopus laevis con seis estadios. Esta rana posee un modo de desarrollo bifásico. La oogénesis para las ...
Cytochemical characterization of the endomembranous system during the oocyte primary growth in Serrasalmus spilopleura (Teleostei, Characiformes, Characidae)
(Churchill LivingstoneEdinburghEscócia, 2005)
Xepac protein and IP3/Ca2+ pathway implication during Xenopus laevis vitellogenesis
(Cambridge University Press, 2013-07)
The objective of this study was to elucidate the signalling pathways initiated by cAMP once inside the Xenopus laevis oocyte, where it triggers and maintains vitellogenin endocytic uptake. Our results showed the presence ...
Adenylate cyclase activity in Xenopus laevis ovarian follicles
(Martinus Nijhoff/Dr. W. Junk Publishers, 1981)
An adenylate cyclase activity was identified and characterized in preparations from Xenopus laevis ovarian tissue and follicles. The enzyme is more active in the presence of Mn2+ than of Mg2+, and it is highly activated ...
High-throughput analysis reveals novel maternal germline RNAs crucial for primordial germ cell preservation and proper migration
(Company of Biologists, 2017-01)
During oogenesis, hundreds of maternal RNAs are selectively localized to the animal or vegetal pole, including determinants of somatic and germline fates. Although microarray analysis has identified localized determinants, ...
Implication of gap junction coupling in amphibian vitellogenin uptake
(Cambridge University Press, 2007-05)
The aim of the present study was to investigate the physiological role and the expression pattern of heterologous gap junctions during Xenopus laevis vitellogenesis. Dye transfer experiments showed that there are functional ...
Caracterización molecular de una adenilil ciclasa de oocito de Xenpus laevis, estudio de estructura-función.
(Universidad de Concepción.Facultad de Ciencias BiológicasDepartamento de Biología Celular y Molecular., 2000)
El objetivo general de este trabajo de tesis fue caracterizar a nivel molecular una adenilil ciclasa (A.C.) de oocito de Xenopus laevis y su interacción con otros componentes que participan en el sistema de transducción ...
