The present study aimed to develop a rapid diagnostic test of aneuploidy in chromosomes 13, 18, 21, X and Y through a program combining short tandem repeat (STR) typing with fluorescence-labeled homologous gene quantitative‑polymerase chain reaction (fHGQ-PCR), which avoids misjudgment risks by using one method alone. Furthermore, fluorescently labeled universal primers not only ensure the accuracy of the results but also reduces the cost of fluorescent labels. The verification of DNA extracted from samples confirmed by karyotype analysis with quantitative fluorescence (QF)-PCR shows that the results obtained using the QF-PCR program are consistent with the results of karyotype analysis in rapidly diagnosing the aneuploidy of chromosomes 13, 18, 21, X and Y.

Background: The establishment of kinetochore-microtubule attachment is essential for error-free chromosome alignment and segregation during cell division. Defects in chromosome alignment result in chromosome instability, birth defects, and infertility. Kinesin-7 CENP-E mediates kinetochore-microtubule capture, chromosome alignment, and spindle assembly checkpoint in somatic cells, however, mechanisms of CENP-E in germ cells remain poorly understood.

Background: Aneuploidy is crucial yet under-explored in cancer pathogenesis. Specifically, the involvement of brain expressed X-linked gene 4 () in microtubule formation has been identified as a potential aneuploidy mechanism. Nevertheless, 's comprehensive impact on aneuploidy incidence across different cancer types remains unexplored.

Research Question: Is it possible to predict blastocyst quality, embryo chromosomal ploidy, and clinical pregnancy outcome after single embryo transfer from embryo developmental morphokinetic parameters?
Design: The morphokinetic parameters of 1011 blastocysts from 227 patients undergoing preimplantation genetic testing were examined. Correlations between the morphokinetic parameters and the quality of blastocysts, chromosomal ploidy, and clinical pregnancy outcomes following the transfer of single blastocysts were retrospectively analyzed.
Results: The morphokinetic parameters of embryos in the high-quality blastocyst group were significantly shorter than those in the low-quality blastocyst group (p < 0.

Aim: This study investigates the impact of sub-toxic cisplatin levels on nuclear and nucleolar abnormalities and chromosome instability in HeLa cells since our current knowledge of cisplatin effects on these parameters is based on studies with high concentrations of cisplatin.
Materials And Methods: HeLa cells were exposed to gradually increasing sub-toxic doses of cisplatin (0.01 to 0.

Aneuploidy eggs are a common cause of human infertility, spontaneous abortion, or trisomy syndromes. The spindle assembly checkpoint (SAC) plays a crucial role in preventing aneuploidy in oocytes, yet it is unclear if additional mechanisms exist to ensure oocyte adherence to this checkpoint. It is now revealed that the microtubule-associated protein NUSAP can prevent oocytes from evading the SAC and regulate the speed of the cell cycle.
