dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Domestic chickens activate a piRNA defense against avian leukosis virus [PDF]

, 2017
PIWI-interacting RNAs (piRNAs) protect the germ line by targeting transposable elements (TEs) through the base-pair complementarity. We do not know how piRNAs co-evolve with TEs in chickens.

Sex Hormones Associate With Amyotrophic Lateral Sclerosis Risk and Survival

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Amyotrophic lateral sclerosis (ALS) risk differs by sex and age, implicating sex hormones as potential modifiers. This study examined plasma levels of biologically active sex hormones and their association with ALS odds and survival in cases (females n = 131, males n = 189) and controls (females n = 138, males n = 150) from the University of ...

Dysregulation of angiogenesis-specific signalling in adult testis results in xenograft degeneration

Scientific Reports, 2017
Ectopic xenografting of testis is a feasible option for preservation of male fertility and angiogenesis plays a pivotal role in xenograft survival and functionality.

Triorchidism: presenting as undescended testis in a case of indirect inguinal hernia

Clinics and Practice, 2016
Triorchidism is the commonest variety of polyorchidism, an entity with more than two testis is an extremely rare congenital anomaly of the testis. Although excision of the abnormal testis is a safer alternative proposed, recent literature suggests more ...

The evolution of sperm morphometry in pheasants [PDF]

, 2007
Postcopulatory sexual selection is thought to be a potent evolutionary force driving the diversification of sperm shape and function across species. In birds, insemination and fertilisation are separated in time and sperm storage increases the duration

Functional Integration of Different‐Sex Gonad Transplants Into the Adult Mouse Hypothalamic Pituitary Gonadal Axis

Advanced Biology, EarlyView.
This study introduces and investigates different‐sex gonad transplants in a mouse model of gender‐affirming hormone therapy. Ovaries and testes implanted into gonadectomized adults exhibit gametogenesis and steroidogenesis independent of the sex of the host.

Nejire/dCBP-mediated control of H3 acetylation and transcriptional regulation by testis-specific Plus3 domain proteins during Drosophila spermatogenesis [PDF]

, 2018
Spermatogenesis describes the development from germ line stem cells to highly specialized sperm. Drosophila melanogaster spermatogenesis is a good model system for chromatin remodelling processes as many of these processes are similar in mammals and in ...

Enzyme‐Regulated Extended Swelling of Hydrogels for Dehiscence‐Less Tissue Expansions

Advanced Functional Materials, EarlyView.
An interpenetrating hydrogel network with swelling under regulation by enzymatic degradation (INSURED) is fabricated to avoid dehiscence. INSURED remains structurally intact post‐implantation, while HYAL injection enables control over the onset and rate of swelling.
