Advanced Science, EarlyView.Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Role of arachidonic acid cascade in Rhinella arenarum oocyte maturation [PDF]
, 2015 There are no studies that document the production of prostaglandins (PGs) or their role in Rhinella arenarum oocyte maturation. In this study, we analysed the effect of arachidonic acid (AA) andprostaglandins (PGs) on maturation, activation and ...

Evaluation of different factors affecting the efficiency of oocytes cryopreservation in the bovine model [PDF]
, 2011 Interest in oocyte cryopreservation has recently increased. Cattle oocytes are sensitive to low temperatures, and despite the efforts of numerous research groups cryopreservation of oocytes remains a difficult task.

In vitro maturation (IVM) of human immature oocytes: is it still relevant?
Reproductive Biology and Endocrinology, 2023 In vitro maturation (IVM) of human immature oocytes has been shown to be a viable option for patients at risk of ovarian hyperstimulation syndrome (OHSS), those seeking urgent fertility preservation and in circumstances where controlled ovarian ...

CRISPR and Gene Augmentation Rescue Trabecular Meshwork Dysfunction in iPSC Models of Lowe Syndrome
Advanced Science, EarlyView.By modeling Lowe syndrome using patient‐derived iPSCs, this study establishes a human disease model that faithfully recapitulates OCRL deficiency‐associated ciliary and cytoskeletal defects. The model enables evaluation of both mutation‐agnostic DNA augmentation and CRISPR‐mediated mutation correction strategies, both of which restore OCRL function and

In vitro maturation of canine oocyte [PDF]
, 2005 Compared to other mammals, the canine oocyte offers a very unusual model of meiosis. Its maturation in vitro, studied only over the past ten years, is still poorly controlled: low rate of metaphase II (10 to 20% vs. over 90% in cattle),

Factors Influencing the In Vitro Maturation (IVM) of Human Oocyte [PDF]
, 2021 In vitro maturation (IVM) of oocytes is a promising assisted reproductive technology (ART) deemed as a simple and safe procedure. It is mainly used in patients with impaired oocyte maturation and in fertility preservation for women facing the risk of ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope
Animal Research and One Health, EarlyView.FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Determination of non-invasive viability markers for human embryos in in vitro fertilization. [PDF]
, 2010 The major challenge currently facing human in vitro fertilization (IVF) programs is the prevention of multiple gestation pregnancies. The replacement of multiple embryos to fertility patients is common practice to increase pregnancy rates.
