Descriptive Analysis of LAP1 Distribution and That of Associated Proteins throughout Spermatogenesis [PDF]

open access: yesMembranes, 2017
Spermatogenesis comprises highly complex differentiation processes. Nuclear envelope (NE) proteins have been associated with these processes, including lamins, lamina-associated polypeptide (LAP) 2 and the lamin B-receptor.

ATAD2 deficiency leads to subfertility by impairing spermatogenesis in mice [PDF]

open access: yesThe Journal of Reproduction and Development
During spermatogenesis, chromatin remodeling regulated by histone modification is essential for spermatogenic cell development, and multiple epigenetic regulators are involved in this process.

Deciphering the role of Hat1 in spermatogenesis: Chromatin organization and beyond [PDF]

open access: yesPeerJ
Spermatogenesis, a core process for male fertility, relies heavily on chromatin organization regulated by histone acetyltransferases (HATs). However, the spatiotemporal expression pattern of histone acetyltransferase 1 (Hat1) in mouse testes and its ...

Distinct Expression Profiles and Novel Targets of MicroRNAs in Human Spermatogonia, Pachytene Spermatocytes, and Round Spermatids between OA Patients and NOA Patients

open access: yesMolecular Therapy - Nucleic Acids, 2017
Human spermatogenesis includes three main stages, namely, the mitosis of spermatogonia, meiosis of spermatocytes, and spermiogenesis of spermatids, which are precisely regulated by epigenetic and genetic factors.

Some aspects on the reproductive cycle of European conger eel, Conger conger (Linnaeus, 1758) (Osteichthyes, Anguilliformes, Congridae) captured from Western Algerian coasts: a histological description of spermatogenesis [PDF]

open access: yesBiodiversity Journal, 2011
The aim of this work was to study the annual reproductive cycle of European conger eel (Conger conger,Linnaeus, 1758) through analysis and description of spermatogenesis.

Establishment of a Coilia nasus Spermatogonial Stem Cell Line Capable of Spermatogenesis In Vitro

open access: yesBiology, 2023
The process by which spermatogonial stem cells (SSCs) continuously go through mitosis, meiosis, and differentiation to produce gametes that transmit genetic information is known as spermatogenesis.

Zbtb40 Deficiency Leads to Morphological and Phenotypic Abnormalities of Spermatocytes and Spermatozoa and Causes Male Infertility

open access: yesCells, 2023
Studies on the gene regulation of spermatogenesis are of unusual significance for maintaining male reproduction and treating male infertility. Here, we have demonstrated, for the first time, that a loss of ZBTB40 function leads to abnormalities in the ...

Establishment of a Coilia nasus Gonadal Somatic Cell Line Capable of Sperm Induction In Vitro

open access: yesBiology, 2022
Coilia nasus is an important economic anadromous migratory fish of the Yangtze River in China. In recent years, overfishing and the deterioration of the ecological environment almost led to the extinction of the wild resources of C.nasus.

Recent Advances in Elongated and Round Spermatid Injection

open access: yesJournal of Urological Surgery, 2021
Azoospermia is commonly identified in patients with infertility. Non-obstructive azoospermia (NOA) includes primary or secondary and incomplete testicular failure. Before testicular sperm extraction (TESE), donor insemination is the only option available

The Spin1 interactor, Spindoc, is dispensable for meiotic division, but essential for haploid spermatid development in mice

open access: yesReproductive Biology and Endocrinology, 2021
In mammals, germline development undergoes dramatic morphological and molecular changes and is epigenetically subject to intricate yet exquisite regulation.
