Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
slug gene expression is associated with the specification and migration of neural crest cells in the African clawed frog Xenopus laevis. We provide evidence that the protein Ying-Yang 1 (YY1) regulates the slug gene expression both indirectly and directly, via a YY1 cis -element in the slug promoter, during Xenopus development. The ability of the YY1 to bind this YY1 cis -element was confirmed by electromobility shift assays and reporter assays. YY1 was detected in the nuclei of ectodermal cells contemporaneously with the process of neural crest specification. The injection of anti-YY1 morpholino, which targeted both YY1 α and YY1 β gene products, depleted YY1 expression below 20% and was lethal at gastrulation. Sublethal depletion of YY1 reduced the length of the anterior-posterior axis and severely inhibited the expression of the neural marker Nrp1 and of the slug gene. Overexpression of YY1 or mutation of the YY1 cis -element reduced the restricted spatial expression of the slug reporter gene in the neural ectoderm border and provoked its expression in the nonneural ectoderm. Chromatin immunoprecipitation indicated that endogenous YY1 interacts directly with the YY1 cis -element of the endogenous slug gene and with the slug gene reporter sequence injected into embryos. The results suggest that YY1 is essential for Xenopus development; is necessary for neural ectoderm differentiation, a prerequisite for neural crest specification; and restricts which cells can form neural crest mesenchyme through directly blocking slug gene activity.
