Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

FEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

FEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

ANIMAL TESTING ALTERNATIVES

Chemical & Engineering News Archive, 2007
TESTING CHEMICALS on animals for human toxicity should be greatly reduced and can potentially be eliminated in favor of experiments using cells, cell lines, or cellular components, says a National Research Council report released last week. Advances in systems biology and methods to test cells and tissues are fundamentally changing the way scientists ...

The Validation and Acceptance of Alternatives to Animal Testing

Toxicology in Vitro, 1999
Validation is the key to the regulatory status of alternative methods. A series of questions are put, to which answers are given, including the following: What is validation? What is meant by "relevance", "reliability" and "purpose"? Why and when is formal validation necessary? What comes before and after a formal validation study?

Harmonisation of Animal Testing Alternatives in China

Alternatives to Laboratory Animals, 2017
More and more countries are lining up to follow the EU's approach and implement a full ban on the sale of cosmetics that have been tested on animals, which has been the case in the EU since 2013. Besides animal welfare considerations, the need for mutual acceptance of data (MAD) and harmonisation of the global market have made the move toward non ...

Alternatives to Animal Testing in the Safety Evaluation of Products

Alternatives to Laboratory Animals, 2002
The conventional method for assessing the safety of products, ranging from pharmaceuticals to agrochemicals, biocides and industrial and household chemicals — including cosmetics — involves determining their toxicological properties by using experimental animals. The aim is to identify any possible adverse effects in humans by using these animal models.

Trend on alternative to animal testing

International Journal of Cosmetic Science, 2007
For the promotion of 3R's (Reduction, Refinement and Replacement) principles of animal tests, the EU and US established the European Center for the Validation of Alternative Methods (ECVAM) and the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM), respectively.
