Spatiotemporal Expression of ARRDC5 in Mammalian Spermatogenesis
Andrology, EarlyView.ABSTRACT Background Spermiogenesis is the final phase of sperm development during which haploid round spermatids transform into specialized spermatozoa and occurs across distinct stages of sperm production in the seminiferous epithelium. Abnormalities in this process lead to malformations and an inability of sperm to fertilize eggs.

Haploid Embryos: Being Like Mommy or Like Daddy?
, 2021 International audienceIn planta haploid embryo induction is a powerful plant breeding tool, but is limited to very few crops. Two recent studies by Wang et al. and Lv et al.

Andrology, EarlyView.ABSTRACT Background During spermiogenesis, protamines (PRMs) replace histones to hypercondense and protect sperm DNA. Rodents and primates express two PRMs (PRM1 and PRM2). Alterations of species‐specific PRM ratios are associated with sub‐ or infertility in mice and humans.

Andrology, EarlyView.ABSTRACT Background Macrozoospermia is a rare form of teratozoospermia characterized by tetraploids, large‐headed spermatozoa with multiple flagella, usually caused by bi‐allelic AURKC mutations. The etiology of atypical phenotypes with a lower proportion of large headed spermatozoa and single flagella however often remains unresolved.

Ploidy‐Dependent Response to Anticancer Drugs of Human Embryonic Stem Cells
Cell Proliferation, EarlyView.Using isogenic hESCs, differing only in their ploidy level, we show the effect of ploidy on the resistance to anticancer drugs. We demonstrate that polyploidy, by itself, confers sensitivity to chemotherapies, leading to higher apoptosis and delayed proliferation, while the loss of p53 reverses the phenotype, demonstrating higher resistance.

Protocols for In Vivo Doubled Haploid (DH) Technology in Maize Breeding: From Haploid Inducer Development to Haploid Genome Doubling [PDF]
, 2022 Doubled haploid (DH) technology reduces the time required to obtain homozygous genotypes and accelerates plant breeding among other advantages. It is established in major crop species such as wheat, barley, maize, and canola.
