Regional requirements for Dishevelled signaling during Xenopus gastrulation: separable effects on blastopore closure, mesendoderm internalization and archenteron formation [PDF]

open access: yes, 2004
During amphibian gastrulation, the embryo is transformed by the combined actions of several different tissues. Paradoxically, many of these morphogenetic processes can occur autonomously in tissue explants, yet the tissues in intact embryos must interact

Developmental toxicity of bisphenol A diglycidyl ether (epoxide resin badge) during the early life cycle of a native amphibian species [PDF]

open access: yes, 2016
Bisphenol A diglycidyl ether (BADGE) is used in packaging materials, in epoxy adhesives, and as an additive for plastics, but it is also a potential industrial wastewater contaminant.

Changes in amino acid and fatty acid composition during early development in cobia (Rachycentron canadum)

open access: yesFrontiers in Marine Science, 2022
An estimation of the utilization of endogenous nutrients from the yolk sac that occurs during embryonic and early larval development can be a valuable approach to studying the nutritional requirements of fish larvae.

Embryos as Patients? Medical Provider Duties in the Age of CRISPR/Cas9 [PDF]

open access: yes, 2017
The CRISPR/Cas9 genome engineering platform is the first method of gene editing that could potentially be used to treat genetic disorders in human embryos. No past therapies, genetic or otherwise, have been intended or used to treat disorders in existent

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A novel homozygous variant in PADI6 is associate with human cleavage-stage embryonic arrest

open access: yesFrontiers in Genetics, 2023
Repeated absence of useable embryos is a difficult problem for infertility patients. Among them, embryonic developmental arrest is more common, but the genetic cause is not known.

Changes in body composition and fatty acid profile during embryogenesis of quillback rockfish (Sebastes maliger) [PDF]

open access: yes, 2009
We investigated developmental changes in the body compositions and fatty acid (FA) profiles of embryos and preparturition larvae of the quillback rockfish (Sebastes maliger).

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Effect of long-term embryo cryopreservation on subsequent frozen embryo transfer outcomes: A retrospective cohort study

open access: yesJournal of Human Reproductive Sciences, 2022
Background: The duration of cryopreservation of embryos and its effect on the subsequent pregnancy outcomes, when they have been frozen for a longer duration remains a matter of concern.
