Enhancement of germ cell apoptosis induced by ethanol in transgenic mice overexpressing Fas Ligand
It was suggested that chronic ethanol exposure could result in testicular germ cell apoptosis, but the mechanism is still unclear. In the present study, we use a model of transgenic mice ubiquitously overexpre...

Impaired reproduction in transgenic mice overexpressing γ-aminobutyric acid transporter I (GAT1)
It is well documented that γ-aminobutyric acid (GABA) system existed in reproductive organs. Recent researches showed that GABAA and GABAB receptors were present in testis and sperm, and might mediate the acrosom...
