DNA fragmentation is a hallmark of apoptosis (programmed cell death). However, the biological function of apoptotic DNA fragmentation remains unclear. Here, we show that DNA fragmentation factor plays an important role for maintaining genomic stability. Inhibition or loss of the DNA fragmentation factor (DFF)/caspase-activated DNase (CAD), whose nuclease activity is responsible for digesting ge...
the purpose of the present study is to investigate the cytotoxicity/apoptotic effect of 2-chloro-2′-deoxyadenosine, cladribine, (2-cda) in the human breast cancer cell line, mda-mb468 (estrogen receptor negative, er−). mtt [3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2h tetrazolium bromide] assay, annexin v-fluorescein/pi and hoechst 33258 staining were used to detect cytotoxicity and cell apopto...
The appropriate management for male partners of couples with recurrent pregnancy loss (RPL) or recurrent implantation failure during in vitro fertilization (IVF) remains unclear. In particular, men with normal semen parameters are often ignored because the “bulk semen parameters” appear normal [1]. Despite normal semen parameters, male partners in couples with RPL or recurrent implantation fail...
Sperm DNA damage has a negative impact on pregnancy rates following assisted reproduction treatment (ART). The aim of the present study was to examine the relationship between sperm DNA fragmentation and live-birth rates after IVF and intracytoplasmic sperm injection (ICSI). The alkaline Comet assay was employed to measure sperm DNA fragmentation in native semen and in spermatozoa following den...
