Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Chromosomal instability in human trophoblast stem cells and placentas

Nature Communications
The human placenta, a unique tumor-like organ, is thought to exhibit rare aneuploidy associated with adverse pregnancy outcomes. Discrepancies in reported aneuploidy prevalence in placentas stem from limitations in modeling and detection methods.

Sperm Sexing in Selected Animals and Humans: Methods, Applications, and Future Prospects

Andrology, EarlyView.
ABSTRACT Background Sperm sexing is a technique that enables the selection of offspring sex by sorting spermatozoa based on their sex chromosomes. This technology has gained increasing attention due to its potential applications in both animal breeding and human‐assisted reproduction.

Impact of Chemotherapy on Sperm Functional Characteristics in Patients With Testicular Germ Cell Tumours

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell tumours (TGCT) are the most common malignancies among young men and represent a major threat to reproductive health. Both the disease itself and oncological treatments, particularly chemotherapy, can compromise spermatogenesis and semen quality.

Single-cell sequencing shows mosaic aneuploidy in most human embryos

The Journal of Clinical Investigation
Mammalian preimplantation embryos often contain chromosomal defects that arose in the first divisions after fertilization and affect a subpopulation of cells — an event known as mosaic aneuploidy. In this issue of the JCI, Chavli et al.

Incidence of Gonadal and Extragonadal Germ Cell Tumours in Patients With Klinefelter Syndrome

Andrology, EarlyView.
ABSTRACT Background Klinefelter's syndrome (KS; 47, XXY) is associated with an altered risk profile for malignancies compared with non‐KS males. In particular, several reports have noted a striking association between KS and extragonadal germ cell tumours (EGCTs), especially in the mediastinum, whereas the risk of testicular germ cell tumours (TGCTs ...

Proteogenomic analysis reveals adaptive strategies for alleviating the consequences of aneuploidy in cancer

The EMBO Journal
Aneuploidy is prevalent in cancer and associates with fitness advantage and poor patient prognosis. Yet, experimentally induced aneuploidy initially leads to adverse effects and impaired proliferation, suggesting that cancer cells must adapt to ...

Mesenchymal Stem Cells From a Klinefelter Syndrome Patient: Functional Characterization and Therapeutic Implications

Andrology, EarlyView.
ABSTRACT Background Cell therapy, particularly those utilizing mesenchymal stem/stromal cells (MSCs), is gaining traction as a therapeutic option for regenerative treatment in patients with limited therapeutic options. Although the safety of MSC‐based interventions is well established, uncertainties remain regarding how genetic abnormalities and ...

Whole Exome Sequencing for Romanian Patients With Neurodevelopmental Disorders Through an International Collaboration

Clinical Genetics, EarlyView.
Whole exome sequencing for Romanian patients with neurodevelopmental disorders through an international collaboration—this study has provided a 50% diagnostic yield for patients with NDDs (27 positive results from 54 patients), supporting the implementation of a WES analysis that can identify SNVs, small INDELs, CNVs, and mitochondrial variants ...

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

Equine Veterinary Journal, EarlyView.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.
