A conditional counterselectable Piga knockout in mouse embryonic stem cells for advanced genome writing applications

open access: yesiScience, 2022
Summary: Overwriting counterselectable markers is an efficient strategy for removing wild-type DNA or replacing it with payload DNA of interest. Currently, one bottleneck of efficient genome engineering in mammals is the shortage of counterselectable ...

Generation of Human CRY1 and CRY2 Knockout Cells Using Duplex CRISPR/Cas9 Technology

open access: yesFrontiers in Physiology, 2019
Circadian clocks are endogenous oscillators essential for orchestrating daily rhythms in physiology, metabolism and behavior. While mouse models have been instrumental to elucidate the molecular mechanism of circadian rhythm generation, our knowledge ...

CRISPR/Cas9-mediated generation of a Plac8 knockout mouse model

open access: yesLaboratory Animal Research, 2018
Placenta specific 8 (PLAC8, also known as ONZIN) is a multi-functional protein that is highly expressed in the intestine, lung, spleen, and innate immune cells, and is involved in various diseases, including cancers, obesity, and innate immune deficiency.

Behavioral analysis of genetically modified mice indicates essential roles of neurosteroidal estrogen

open access: yesFrontiers in Endocrinology, 2011
Brain aromatase is expressed only in the nerve cells of specific brain regions with a transient peak at the neonatal period when sexual behaviors become organized. Aromatase knockout (ArKO) mouse, generated to give light on the physiological functions of

Production of knockout mouse lines with Cas9

open access: yesMethods, 2021
Knockout mice are used extensively to explore the phenotypic effects of mammalian gene dysfunction. With the application of RNA-guided Cas9 nuclease technology for the production of knockout mouse lines, the time, as well as the resources needed, to progress from identification of a gene of interest to production of a knockout line is significantly ...

Absence of BBSome function leads to astrocyte reactivity in the brain

open access: yesMolecular Brain, 2019
In humans, dysfunctional primary cilia result in Bardet-Biedl syndrome (BBS), which presents with clinical features including intellectual disabilities, obesity, and retinal degeneration, and, in mouse models, the added feature of hydrocephalus.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Apelin protects against NMDA-induced retinal neuronal death via an APJ receptor by activating Akt and ERK1/2, and suppressing TNF-α expression in mice

open access: yesJournal of Pharmacological Sciences, 2017
Glutamate excitotoxicity mediated by N-methyl-d-aspartate (NMDA) receptors is an important cause of retinal ganglion cell death in glaucoma. To elucidate whether apelin protects against retinal neuronal cell death, we examined protective effects of ...
