Clearance of germ granules in the soma [PDF]

open access: yesF1000 Biology Reports, 2009
Germ granules are ribonucleoprotein complexes specifically segregated into germ cell lineages in diverse organisms. Recent studies indicate that multiple mechanisms are involved in the clearance of germ granules and their components in somatic cells in Caenorhabditis elegans embryos.

Vitrification of human immature oocytes before and after in vitro maturation: a review [PDF]

open access: yes, 2017
The use of immature oocytes subjected to in vitro maturation (IVM) opens interesting perspectives for fertility preservation where ovarian reserves are damaged by pathologies or therapies, as in PCO/PCOS and cancer patients. Human oocyte cryopreservation

El sistema reproductor femenino de Zearaja chilensis (Guichenot, 1848) (Chondrichthyes, Rajidae): Gametogénesis y validación microscópica de los criterios de madurez [PDF]

open access: yes, 2015
Los condrictios son extremadamente susceptibles a la explotación pesquera debido, entre otras cosas, a sus adaptaciones reproductivas. Los conocimientos básicos de sus parámetros reproductivos son esenciales, ya sea desde el punto de vista ecológico como

Protein-based condensation mechanisms drive the assembly of RNA-rich P granules

open access: yeseLife, 2021
Germ granules are protein-RNA condensates that segregate with the embryonic germline. In Caenorhabditis elegans embryos, germ (P) granule assembly requires MEG-3, an intrinsically disordered protein that forms RNA-rich condensates on the surface of PGL ...

Germ Granule Evolution Provides Mechanistic Insight into Drosophila Germline Development

open access: yesMolecular Biology and Evolution, 2023
Abstract The copackaging of mRNAs into biomolecular condensates called germ granules is a conserved strategy to posttranscriptionally regulate germline mRNAs. In Drosophila melanogaster, mRNAs accumulate in germ granules by forming homotypic clusters, aggregates containing multiple transcripts from the same gene. Nucleated by Oskar (Osk),

Unidirectional P-body transport during the yeast cell cycle. [PDF]

open access: yesPLoS ONE, 2014
P-bodies belong to a large family of RNA granules that are associated with post-transcriptional gene regulation, conserved from yeast to mammals, and influence biological processes ranging from germ cell development to neuronal plasticity.

A single transcription factor is sufficient to induce and maintain secretory cell architecture [PDF]

open access: yes, 2017
We hypothesized that basic helix–loop–helix (bHLH) MIST1 (BHLHA15) is a “scaling factor” that universally establishes secretory morphology in cells that perform regulated secretion.

Tripartite phase separation of two signal effectors with vesicles priming B cell responsiveness. [PDF]

open access: yes, 2020
Antibody-mediated immune responses rely on antigen recognition by the B cell antigen receptor (BCR) and the proper engagement of its intracellular signal effector proteins.

DLC-1 facilitates germ granule assembly in Caenorhabditis elegans embryo

open access: yesMolecular Biology of the Cell, 2022
Interactions between DLC-1/LC8 family protein and several germ granule components suggest a role for DLC-1 in promoting phase separation of non-membrane bound cellular organelles. This function of DLC-1 was genetically validated and was independent of dynein motor or cell polarity.

A new species of Daldinia (Xylariaceae) from the Argentine subtropical montane forest [PDF]

open access: yes, 2016
Based on a combination of morphological, molecular phylogenetic and chemotaxonomic evidence, a new species of Daldinia from Northwest of Argentina is described. Daldinia korfii is morphologically related to D.
