Oral Engineered Extracellular Vesicles Based on Ion Exchange Strategy for Multipronged Management of Wilson's Disease Complicated with Reproductive Dysfunction Therapy

Advanced Science, EarlyView.
This study reports for the first time an oral targeted nanomedicine that conducts ion exchange through engineered Ganoderma‐derived extracellular vesicle, managing both the in‐copper and ex‐copper in a multi‐pronged approach, offering a promising therapeutic strategy for addressing WD with reproductive dysfunction.

Understanding spermatogenesis is a prerequisite for treatment

Reproductive Biology and Endocrinology, 2003
Throughout spermatogenesis multiplication, maturation and differentiation of germ cells results in the formation of the male gamete. The understanding of spermatogenesis needs detailed informations about the organization of the germinal epithelium, the ...

SRSF2 is required for mRNA splicing during spermatogenesis

BMC Biology, 2023
Background RNA splicing plays significant roles in fundamental biological activities. However, our knowledge about the roles of alternative splicing and underlying mechanisms during spermatogenesis is limited. Results Here, we report that Serine/arginine-

RNA from a simple-tandem repeat is required for sperm maturation and male fertility in Drosophila melanogaster. [PDF]

, 2019
Tandemly-repeated DNAs, or satellites, are enriched in heterochromatic regions of eukaryotic genomes and contribute to nuclear structure and function. Some satellites are transcribed, but we lack direct evidence that specific satellite RNAs are required ...

A Novel Cultivation System for Germ Cell Proliferation and Sustaining Whole Testicular Niche

Advanced Science, EarlyView.
A hydrogel microneedle‐based system enables whole testicular cultivation, supporting spermatogonial proliferation and enhancing spermatogenesis in vitro. This ‘whole testicular spermatogonia pool’ (WTSP) significantly increases spermatid production and fertility potential in mice. This system also promotes spermatogonial expansion in human fetal testes,

Testicular expression of TDRD1, TDRD5, TDRD9 and TDRD12 in azoospermia. [PDF]

, 2020
BACKGROUND: Tudor domain-containing proteins (TDRDs) play a critical role in piRNA biogenesis and germ cell development. piRNAs, small regulatory RNAs, act by silencing of transposons during germline development and it has recently been shown in animal ...

Mitochondrial dynamics during spermatogenesis

Journal of Cell Science, 2020
Mitochondrial fusion and fission (mitochondrial dynamics) are homeostatic processes that safeguard normal cellular function. This relationship is especially strong in tissues with constitutively high energy demands, such as brain, heart and skeletal ...
