同源异型基因(hox gene) 相关知识点: 试题来源: 解析 答案:谱系异型基因是指存在于多种无脊椎动物和高等脊椎动物中的一类在体节发育中起发育关键作用的核酸,在基因表达调控中具有主导性作用。这些基因都含有一个称为同源框的180bp长的DNA序列,编码的同源异型结构域形成的α螺旋转角α螺旋结构作为作用因子启动特定基因...

A Hox gene is defined as an evolutionary homologue of transcription factor genes found in all vertebrates, with multiple complexes in mammals. These genes exhibit colinearity in their expression along the body axis, reflecting their order on the chromosome. ...
Hox gene Thesaurus Medical Encyclopedia Wikipedia (hŏks) n. Any of a group of homeobox genes that exist as clusters in animals, especially in vertebrates, and determine the identity and locations of body parts along the anterior-posterior body axis in a developing fetus or larva. ...
can function withinDrosophilato activate gene expression in aDeformed-specific pattern, whereas the enhancer region ofDrosophila DeformedactivatesHoxb4-specific expression in the mouse hindbrain (Malickiet al., 1992). Similar results have been obtained forHox1orthologues (Pöpperlet al., 1995), sugges...
Hox genes are central to metazoan body plan formation, patterning and evolution, playing a critical role in cell fate decisions early in embryonic development in invertebrates and vertebrates. While the archetypical Hox gene cluster consists of members of nine ortholog groups (HOX1-HOX9), arrayed ...

HOXgenes are expressed in adult cells as positional identity markers [47,48]. Because the cells are in a quiescent state, their collagen synthesis gene expression is upregulated. In our suggested model, however, if an injury compromises the skin’s integrity, fibroblasts can sense the changes ...
Hox gene collinearity; temporal collinearity; Noether theory; self-similarity; double strand break; split Hox clusters; chicken limb growth1. Introduction In 1978 E.B. Lewis discovered a fundamental property of developmental biology: Hox gene collinearity (HGC). HGC is the long-range interaction of...
