Establishment and optimization of the two‐step induction system for generating primordial germ cell‐like cells from chicken embryonic stem cells

open access: yesFEBS Open Bio, EarlyView.
This study optimizes a two‐step induction system to generate PGCLCs from chicken ESCs. The induced cells express germline markers and migrate to gonads in ovo, offering a novel approach for avian genetic resource conservation. Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs.

The impact of Hnrnpl deficiency on transcriptional patterns of developing muscle cells

open access: yesFEBS Open Bio, EarlyView.
We performed nanopore whole‐transcriptome sequencing comparing RNA from Hnrnpl‐knockdown versus control C2C12 myoblasts to investigate the contributions of Hnrnpl to muscle development. Our results indicate that Hnrnpl regulates the expression of genes involved with Notch signaling and skeletal muscle, particularly splicing patterns of specific muscle ...

Overexpression of CDT1 inhibits cell cycle progression at S phase by interacting with the mini‐chromosome maintenance complex and causes DNA damage

open access: yesFEBS Open Bio, EarlyView.
CDT1 is an essential protein for DNA replication licensing that loads the MCM complex, the eukaryotic replicative DNA helicase, onto replication origins. Overexpression of CDT1 induces cell cycle arrest at the S phase. Here we showed CDT1 inhibits the progression of replication forks by interacting with the MCM complex, leading to the stalling and ...

Salivary Fluoride level in preschool children after toothbrushing with standard and low fluoride content dentifrice, using the transversal dentifrice application technique: pilot study [PDF]

open access: yesRGO: Revista Gaúcha de Odontologia, 2008
Objective: To investigate the salivary fluoride concentration in pre-school children after toothbrushing with dentifrice containing standard (1100ppmF/NaF) and low (500ppmF/NaF) fluoride concentration, using the transversal technique of placing the ...

The use of fluoride dentifrices in children: conceptual bases in a confusing context: a topic review

open access: yesRevista Facultad de Odontología Universidad de Antioquia, 2017
Fluoride toothpastes have long been recommended as part of the measures to prevent dental caries. Controversial findings suggest that an inappropriate use of this type of dentifrices can significantly contribute to the total intake of fluoride by ...
