Coupling of Active Motion and Advection Shapes Intracellular Cargo Transport [PDF]

open access: yesPhys. Rev. Lett. 109 (2012) 028104, 2012
Intracellular cargo transport can arise from passive diffusion, active motor-driven transport along cytoskeletal filament networks, and passive advection by fluid flows entrained by such motor/cargo motion. Active and advective transport are thus intrinsically coupled as related, yet different representations of the same underlying network structure ...

PABPN1 Couples the Polyadenylation and Translation of Maternal Transcripts to Mouse Oocyte Meiotic Maturation

open access: yesAdvanced Science, EarlyView.
This study reveals that cytoplasmic PABPN1 is essential for mouse oocyte meiotic maturation by coordinating polyadenylation, translation, and degradation of maternal mRNAs. Pabpn1 knockout disrupts CDK1 activation, spindle formation, and chromosome alignment by impairing maturation‐promoting factor (MPF) regulation and BTG4‐mediated deadenylation ...

THE INFLUENCE OF ADEMOL ON OOCYTE AND THEIR FOLICULAR CELLS

open access: yesВісник проблем біології і медицини, 2018
Today àdemole’s influence on functional ovaries remains unexplored. Data about the treatment of àdemol on oocytes and cells of their follicular environment are absent.

Germ Cell Responses to Stress: The Role of RNP Granules

open access: yesFrontiers in Cell and Developmental Biology, 2019
The ability to respond to stress is critical to survival for animals. While stress responses have been studied at both organismal and cellular levels, less attention has been given to the effect of stress on the germ line. Effective germ line adaptations

Intermediate Filament Protein BFSP1 Maintains Oocyte Asymmetric Division by Modulating Spindle Length

open access: yesAdvanced Science, EarlyView.
Different from mitosis, the female meiosis undergoes asymmetric division that produces haploid oocytes and polar body, which is essential for retaining maternal components to support subsequent fertilization and embryo development. However, the underlying mechanisms are still largely unknown.

Differential Dynamic Microscopy can be applied to Differential Interference Contrast images despite shadowing effects [PDF]

open access: yesarXiv, 2022
During In Vitro Fertilisation (IVF), combining time-lapse contrast microscopy with suitable image processing techniques could facilitate non-invasive classification of oocyte health, driving oocyte selection to maximise success rates. One image processing technique, Differential Dynamic Microscopy (DDM), has been used in a variety of microscopy ...

Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future

open access: yesAdvanced Intelligent Systems, EarlyView.
Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

Serous papillary adenocarcinoma possibly related to the presence of primitive oocyte-like cells in the adult ovarian surface epithelium: a case report

open access: yesJournal of Ovarian Research, 2011
Introduction The presence of oocytes in the ovarian surface epithelium has already been confirmed in the fetal ovaries. We report the presence of SSEA-4, SOX-2, VASA and ZP2-positive primitive oocyte-like cells in the adult ovarian surface epithelium of ...
