Chromosomal segregation in spermatozoa of 14 Robertsonian translocation carriers.
Male carriers of Robertsonian (Rob) translocations can have fertility problems associated with low sperm counts and abnormal sperm morphology. In this study, spermatozoa from 14 Rob translocation carriers, seven der(13;14), two der(13;15), two der(14;15), two der(14;21) and one der(21;22), were tested by fluorescence in-situ hybridization (FISH) for the chromosomes involved, to study meiotic se...
متن کاملSperm parameters and DNA fragmentation of balanced chromosomal rearrangements carriers.
INTRODUCTION Somatic chromosomal rearrangements that occur in infertile males are thought to be one of the major genetic factors influencing male infertility. The objective of this retrospective study was to evaluate sperm parameters in a group of patients with balanced translocations. MATERIAL AND METHODS We analyzed semen of 84 balanced somatic translocation carriers [35 Robertsonian transl...
متن کاملPropranolol induced chromosomal aberrations in Chinese hamster ovary cell line
Propranolol (PL), a non-selective beta-blocker, is a cardiovascular drug widely used to treat hypertension. The present study was concerned with assessing the cytogenetic effects of this drug on Chinese hamster ovary (CHO) cell line. MTT assay was then carried out to determine the cytotoxicity index (IC50) of the drug. The IC50 value of PL was 0.43±0.02 mM. To investigate the clastogenic effect...
متن کاملCell cycle control of chromosomal DNA replication.
Accurate replication and segregation of chromosomal DNA is essential for high-fidelity transmission of genetic information from generation to generation. Eukaryotic cells typically replicate by first duplicating their chromosomes during the S phase followed by their segregation between two daughter cells during the M phase. Over recent years, advances in our understanding of this process at the...
