Identification and validation of stable reference genes for quantitative real time PCR in different minipig tissues at developmental stages

open access: yesBMC Genomics, 2022
Background Quantitative real time PCR (qPCR) is a powerful tool to evaluate mRNA expression level. However, reliable qPCR results require normalization with validated reference gene(s).

Neural stemness contributes to cell tumorigenicity

open access: yesCell & Bioscience, 2021
Background Previous studies demonstrated the dependence of cancer on nerve. Recently, a growing number of studies reveal that cancer cells share the property and regulatory network with neural stem/progenitor cells.

Carnosic acid improves porcine early embryonic development by inhibiting the accumulation of reactive oxygen species

open access: yesThe Journal of Reproduction and Development, 2020
Carnosic acid (CA), a natural catechol rosin diterpene, is used as an additive in animal feeds and human foods. However, the effects of CA on mammalian reproductive processes, especially early embryonic development, are unclear.

The rhythmic coupling of Egr-1 and Cidea regulates age-related metabolic dysfunction in the liver of male mice

open access: yesNature Communications, 2023
The liver lipid metabolism of older individuals canbecome impaired and the circadian rhythm of genes involved in lipid metabolism is also disturbed. Although the link between metabolism and circadian rhythms is already recognized, how these processes are

Both prokaryotes and eukaryotes produce an immune response against plasmids with 5ʹ-GTTTGTT-3ʹ

open access: yesCell & Bioscience, 2022
In the evolutionary “arms race” from prokaryotes to eukaryotes, some memories of foreign DNA have been conserved for defensive purposes. Shortly after invasion by the plasmid, pEGFP-N1, the conserved the defense gene, isg15, was activated in the ...

Loss of WTAP Impairs Early Parthenogenetic Embryo Development

open access: yesAnimals, 2021
m6A is one of the most common and abundant modifications of RNA molecules present in eukaryotes. The methyltransferase complex, consisting of methyltransferase-like 3 (METTL3), METTL14, and WTAP, is responsible for the m6A modification of RNA.

Distinct Roles of Smooth Muscle and Non-muscle Myosin Light Chain-Mediated Smooth Muscle Contraction

open access: yesFrontiers in Physiology, 2020
Both smooth muscle (SM) and non-muscle (NM) myosin II are expressed in hollow organs such as the bladder and uterus, but their respective roles in contraction and corresponding physiological functions remain to be determined.

Animal models [PDF]

open access: yesBritish Medical Bulletin, 2000
Animal models of cerebral ischaemia mimic at best less than 25% of all strokes. Compounds which prove efficacious in animal models should, therefore, only be expected to improve outcome in a quarter of all strokes. If trials for acute stroke are to succeed, stroke subgroups represented by the animal models should be targeted. For the other subgroups, e.

PER1 Phosphorylation Specifies Feeding Rhythm in Mice

open access: yesCell Reports, 2014
Organization of circadian behavior, physiology, and metabolism is important for human health. An S662G mutation in hPER2 has been linked to familial advanced sleep-phase syndrome (FASPS).

Methoxychlor induces oxidative stress and impairs early embryonic development in pigs

open access: yesFrontiers in Cell and Developmental Biology, 2023
Introduction: Methoxychlor (MXC) is an organochlorine pesticide (OCP) that was formerly used worldwide as an insecticide against pests and mosquitoes. However, MXC is not biodegradable and has lipophilic characteristics; thus, it accumulates in organisms
