概括

全转网酸是已知的脊椎动物原体,影响软体动物早期发育. 对Lymnaea stagnalis,Physa fontinalis和Bithynia tentaculata的研究表明,视网酸特别影响眼睛的形成和形态发生.

科学领域:

发育生物学是发展生物学.
甲状腺学甲状腺学是一门学科.
类动物研究研究

背景情况:

全转网红酸 (ATRA) 是脊椎动物发育中的一个成熟的原体.
了解ATRA对无脊椎动物发育的影响,可以揭示保存的生物通路.
软体动物的发展提供了一个研究早期形态遗传过程的模型.

研究的目的:

为了研究软体动物形态发生对全转网红酸的敏感性.
为了确定ATRA是否影响脚动物物种的特定发育过程.
为了比较ATRA在软体动物和脊椎动物中的致病效应.

主要方法:

对Lymnaea stagnalis,Physa fontinalis和Bithynia tentaculata的胚胎暴露于各种度的全转网红酸.
观察和记录发育异常,包括眼睛形成,发育停止和变形.
脉冲治疗以识别敏感的发育阶段,特别是胃流动期间.

主要成果:

在所有三种物种中,低度的全转网红酸 (10-7M) 特别影响了眼睛的形成.
在Lymnaea stagnalis中,较高度 (10^-6 M) 导致了更广泛的缺陷,包括发育停止和形形.
胚胎对视网酸的敏感性在胃化过程中是最高的,随后的敏感性迅速下降,这表明了特定的,无毒的机制.

结论:

软体动物胚胎对全转网红酸表现出敏感性,特别影响眼睛发育和整体形态发生.
观察到的产物效应表明脊椎动物和软体动物早期发育之间的分子通路得到保护.
在胃化过程中雷酸的影响凸显了这些无脊椎动物发育敏感性的关键时期.

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Gastrulation

Gastrulation

Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...
