The role of spatial averaging in the precision of gene expression patterns [PDF]

open access: yes, 2009
During embryonic development, differentiating cells respond via gene expression to positional cues from morphogen gradients. While gene expression is often highly erratic, embryonic development is precise. We show by theory and simulations that diffusion of the expressed protein can enhance the precision of its expression domain.

CXCL5 Downregulation in Villous Tissue Is Correlated With Recurrent Spontaneous Abortion

open access: yesFrontiers in Immunology, 2021
Recurrent spontaneous abortion (RSA) affects 5% of childbearing-age women worldwide. Inadequate trophoblast invasion is one of the main reasons for the development of RSA; however, the underlying molecular mechanisms for RSA have not been fully ...

USP25 Regulates the Proliferation and Apoptosis of Ovarian Granulosa Cells in Polycystic Ovary Syndrome by Modulating the PI3K/AKT Pathway via Deubiquitinating PTEN

open access: yesFrontiers in Cell and Developmental Biology, 2021
Background: Polycystic ovarian syndrome (PCOS) is an endocrine-related disease related to abnormal folliculogenesis and is a leading cause of infertility worldwide.

Retinoic Acid Signaling Plays a Crucial Role in Excessive Caffeine Intake-Disturbed Apoptosis and Differentiation of Myogenic Progenitors

open access: yesFrontiers in Cell and Developmental Biology, 2021
Whether or not the process of somitogenesis and myogenesis is affected by excessive caffeine intake still remains ambiguous. In this study, we first showed that caffeine treatment results in chest wall deformities and simultaneously reduced mRNA ...

Mechanical Plasticity of Cell Membranes Enhances Epithelial Wound Closure [PDF]

open access: yesPhys.Rev.Research. 6 (2024) L012036, 2023
During epithelial wound healing, cell morphology near the healed wound and the healing rate vary strongly among different developmental stages even for a single species like \textit{Drosophila}. We develop deformable particle (DP) model simulations to understand how variations in cell mechanics give rise to distinct wound closure phenotypes in the ...

Nanocomposites based on nanoceria regulate the immune microenvironment for the treatment of polycystic ovary syndrome

open access: yesJournal of Nanobiotechnology, 2023
The immune system is closely associated with the pathogenesis of polycystic ovary syndrome (PCOS). Macrophages are one of the important immune cell types in the ovarian proinflammatory microenvironment, and ameliorate the inflammatory status mainly ...

Regulation and Function of Chemokines at the Maternal–Fetal Interface

open access: yesFrontiers in Cell and Developmental Biology, 2022
Successful pregnancy requires the maternal immune system to tolerate the semi-allogeneic embryo. A good trophoblast function is also essential for successful embryo implantation and subsequent placental development.
