GSK3 Inhibition During Annelid Head Regeneration Results in a Hyper‐Proliferative Blastema and Impaired Differentiation

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
A whole‐body regenerative annelid was treated with a GSK3 inhibitor. While posterior regeneration was mostly normal, GSK3 inhibition prevented differentiation of anterior‐specific structures and instead produced a persistent, oversized, hyper‐proliferative blastema. This suggests that GSK3 promotes anterior identity and halts proliferation during axial

A frozen-thawed embryo transfer program improves the embryo utilization rate.

Chinese medical journal, 2010
Frozen-thawed embryo transfer (FET) is the most common way to prevent serious late ovarian hyperstimulation syndrome and increase the cumulative pregnancy rate. We evaluated the effectiveness of an FET program for improving the embryo implantation and clinical pregnancy rates, and ultimate embryo utilization rate in infertility treatment.Patients ...

Outcome of cryopreserved-thawed embryo transfer in the GnRH agonist versus antagonist protocol [PDF]

, 2012
Background: GnRH agonist and antagonist were developed to control the premature release of LH surge. There is some difference between two protocols. Objective: We compared the outcome of frozen-thawed embryo transfer in infertile women who used GnRH ...

Recent Advances in Top‐Down Proteomics for Single‐Cell Research

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Individual cells have distinctive molecular characteristics, including biologically relevant proteoforms. Although single‐cell (SC) molecular omics offer unprecedented insights into cellular heterogeneity and function, the characterization of proteoforms in SCs remains an uncharted territory.

Human Prostate Cell Lines: Derivation, Molecular Characteristics and Appropriate Use

The Prostate, EarlyView.
ABSTRACT Background Research on prostate cancer and benign prostatic hyperplasia depends on a small number of immortalized human cell lines established between 1977 and 2001, most of them from advanced metastatic disease. The cell lines differ from one another in androgen receptor status, prostate‐specific antigen secretion, p53 status, karyotype and ...

Dihydrotanshinone I Targets MIF to Inhibit GSK‐3β/β‐Catenin Axis‐Mediated Invasion and Metastasis in Gastric Cancer

Phytotherapy Research, EarlyView.
DHT directly binds to MIF and subsequently blunts AKT signaling, which restores the kinase activity of GSK‐3β. The reactivated GSK‐3β then promotes the phosphorylation (Ser33/37/Thr41) and proteasomal degradation of β‐catenin, thereby preventing its nuclear translocation and inhibiting the transcription of EMT‐related genes (e.g., Snail and Twist ...

Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

Environmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.
