Abstract

Studies on cell polarity proteins and planar cell polarity (PCP) proteins date back to almost 40 years ago in Drosophila and C. elegans when these proteins were shown to be crucial to support apico-basal polarity and also directional alignment of polarity cells across the plane of an epithelium during morphogenesis. In adult mammals, cell polarity and PCP are most notable in cochlear hair cells. However, the role of these two groups of proteins to support spermatogenesis was not explored until a decade earlier when several proteins that confer cell polarity and PCP proteins were identified in the rat testis. Since then, there are several reports appearing in the literature to examine the role of both cell polarity and PCP in supporting spermatogenesis. Herein, we provide an overview regarding the role of cell polarity and PCP proteins in the testis, evaluating these findings in light of studies in other mammalian epithelial cells/tissues. Our goal is to provide a timely evaluation of these findings, and provide some thought provoking remarks to guide future studies based on an evolving concept in the field.

细胞极性和平面细胞极性蛋白在精子发生中的作用。
关于细胞极性蛋白和平面细胞极性(PCP)蛋白的研究可以追溯到近40年前,在果蝇和秀丽隐杆线虫中,这些蛋白被证明在形态发生过程中对支持顶基极性和极性细胞在上皮平面上的定向排列至关重要。在成年哺乳动物耳蜗毛细胞中,细胞极性和PCP最为显著。然而,直到十年前,当在大鼠睾丸中发现了几种赋予细胞极性和PCP蛋白的蛋白质时,这两组蛋白质在支持精子发生中的作用才被探索出来。从那时起,文献中出现了一些报告来研究细胞极性和PCP在支持精子发生中的作用。在此,我们概述了细胞极性和PCP蛋白在睾丸中的作用,并结合其他哺乳动物上皮细胞/组织的研究对这些发现进行了评估。我们的目标是对这些发现进行及时的评估,并提供一些发人深省的评论,以指导基于该领域不断发展的概念的未来研究。

期刊介绍: As the discipline of biochemistry and molecular biology have greatly advanced in the last quarter century, significant contributions have been made towards the advancement of general medicine, genetics, immunology, developmental biology, and biophysics. Investigators in a wide range of disciplines increasingly require an appreciation of the significance of current biochemical and molecular biology advances while, members of the biochemical and molecular biology community itself seek concise information on advances in areas remote from their own specialties. Critical Reviews in Biochemistry and Molecular Biology believes that well-written review articles prove an effective device for the integration and meaningful comprehension of vast, often contradictory, literature. Review articles also provide an opportunity for creative scholarship by synthesizing known facts, fruitful hypotheses, and new concepts. Accordingly, Critical Reviews in Biochemistry and Molecular Biology publishes high-quality reviews that organize, evaluate, and present the current status of high-impact, current issues in the area of biochemistry and molecular biology. Topics are selected on the advice of an advisory board of outstanding scientists, who also suggest authors of special competence. The topics chosen are sufficiently broad to interest a wide audience of readers, yet focused enough to be within the competence of a single author. Authors are chosen based on their activity in the field and their proven ability to produce a well-written publication.
