DOI: 10.1002/jmor.21446

Abstract: Details of spermatogenesis and sperm organization are often useful for reconstructing the phylogeny of closely related taxa of invertebrates. Here, the spermiogenesis and the ultrastructure of sperm were studied in two marine demosponges, Crellomima imparidens… read more here.

recommendations! Published in 2020 at "Molecular Reproduction and Development"

DOI: 10.1002/mrd.23396

Abstract: We isolated the transmembrane and coiled‐coil domains 2 (Tmco2) gene using a polymerase chain reaction‐based subtraction technique. Tmco2 is predominantly expressed in rat testes starting from 4 weeks of age. Rat TMCO2 consists of 187… read more here.

DOI: 10.1016/j.gene.2018.01.056

Abstract: Prohibitin (PHB) is a ubiquitous, evolutionarily conserved protein that is mainly localized in the inner mitochondrial membrane and exerts various mitochondrial functions. Here, we first cloned the phb gene from P. esculenta. The Pe-PHB protein… read more here.

DOI: 10.1016/j.gene.2018.10.021

Abstract: Kinesin-14 KIFC1 plays an important role in vesicular transport, microtubule organization, and spermiogenesis. In this study, we first investigated the microtubule distribution and expression pattern of KIFC1 during spermiogenesis of P. esculenta. Microtubules are abundant… read more here.

DOI: 10.1016/j.jcz.2021.09.001

Abstract: Abstract We describe in this paper the morphology of the male reproductive system, the spermiogenesis and the sperm ultrastructure of the drugstore beetle S. paniceum (L) (Coleoptera, Ptinidae). The male reproductive apparatus has a pair… read more here.

DOI: 10.1016/j.jprot.2020.103891

Abstract: Lysine crotonylation (Kcr) is a recently-discovered type of post-translational modification. Although Kcr has been reported in many species, little is known about this process in crustaceans. In this study, pan anti-lysine crotonylation antibody enrichment and… read more here.

DOI: 10.1016/j.micron.2019.03.006

Abstract: Autophagy is a subcellular process that is extensively involved in spermiogenesis. In this study, we observed ultrastructural malformation of acrosome and mitochondrial cristae during the spermiogenesis of Chinese soft-shelled turtle due to the inhibition of… read more here.

DOI: 10.1016/j.ydbio.2018.02.013

Abstract: Successful fertilization requires that sperm are activated prior to contacting an oocyte. In C. elegans, this activation process, called spermiogenesis, transforms round immobile spermatids into motile, fertilization-competent spermatozoa. We describe the phenotypic and genetic characterization… read more here.

DOI: 10.1038/s41598-017-03867-7

Abstract: Classification of morphological features in biological samples is usually performed by a trained eye but the increasing amount of available digital images calls for semi-automatic classification techniques. Here we explore this possibility in the context… read more here.

DOI: 10.1080/15548627.2022.2096396

Abstract: ABSTRACT Sperm mitochondria generally exhibit distinctive and diverse morphologies in animals and plants. Bryophytes, a plant group consisting of liverworts, mosses, and hornworts, produce motile male gametes, called spermatozoids, that possess a fixed number of… read more here.

DOI: 10.1093/hmg/ddab185

Abstract: Asthenoteratospermia is a common cause of male infertility. Recent studies have revealed that CFAP65 mutations lead to severe asthenoteratospermia due to acrosome hypoplasia and flagellum malformations. However, the molecular mechanism underlying CFAP65-associated sperm malformation is… read more here.
