WebA major focus has been the role of Sonic Hedgehog (Shh) and its main signaling targets, which together regulate the late morphogenetic realization of early patterning cues triggered by Shh. Although proposed to act as a morphogen, how Shh instructs digit identity is still poorly understood. We recently showed Shh acts only transiently, as a ... WebRobert E. Hill, Laura A. Lettice, in Kaufman's Atlas of Mouse Development Supplement, 2016 Conclusion. Recent studies have shown that limb development occurs as a highly integrated process in which, at each stage, the cells must incorporate a varied selection of signals. Thus it is important to understand limb development as a four-dimensional …

Webp63 and p73 are members of the p53 protein family and have been shown to play an important role in cell death, development, and tumorigenesis. In particular, p63 has been shown to be involved in the WebOct 31, 2024 · Sonic Hedgehog (SHH) signaling has been most widely known for its role in specifying region and cell-type identity during embryonic morphogenesis. This mini-review accompanies a 2024 SFN mini-symposium that addresses an emerging body of research focused on understanding the diverse roles for Shh signaling in a wide range of contexts … Sonic hedgehog protein (SHH) is encoded for by the SHH gene. The protein is named after the character Sonic the Hedgehog. This signaling molecule is key in regulating embryonic morphogenesis in all animals. SHH controls organogenesis and the organization of the central nervous system, limbs, digits and … See more The hedgehog gene (hh) was first identified in the fruit fly Drosophila melanogaster in the classic Heidelberg screens of Christiane Nüsslein-Volhard and Eric Wieschaus, as published in 1980. These See more SHH undergoes a series of processing steps before it is secreted from the cell. Newly synthesised SHH weighs 45 kDa and is referred to as the preproprotein. As a secreted protein, it contains a short signal sequence at its N-terminus, which is recognised by the See more The gene has been linked to a condition known as holoprosencephaly, which can result in severe brain, skull and facial defects, causing a … See more • Dorus S, Anderson JR, Vallender EJ, Gilbert SL, Zhang L, Chemnick LG, et al.
