Studies of knockout (KO) mice with defects in the endolysosomal two-pore channels (TPCs) have shown TPCs to be involved pathophysiological processes, including heart and muscle function, metabolism, immunity, cancer, viral infection. With objective studying TPC2's roles for first time a large, more humanlike animal model, TPC2 KO pigs were produced using CRISPR-Cas9. A major problem CRISPR-Cas9...

In rodents and swine, individual differences in a broad range of characteristics correlate with intrauterine position during fetal life. By identifying the intrauterine position of mice at cesarean delivery, we can predict reliably postnatal reproductive traits such as genital morphology, timing of puberty, length of estrous cycles, timing of reproductive senescence, sexual attractiveness, sexu...

In utero, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure causes abnormal ventral, dorsolateral, and anterior prostate development in C57BL/6J mice. Androgens, mesenchymal-epithelial interactions, and growth factor expression all have roles in initiating and regulating development and growth of the prostate. Epidermal growth factor (EGF) and transforming growth factor alpha (TGF-alpha), bot...

The thyroid structural changes in pregnant ewes and their fetuses were investigated. Out of 100 pairs of thyroid glands collected from ewes and their fetuses at the local municipal abattoir in Ahvaz city of Khuzestan province, multiple lesions were seen in 59% and 21% of the thyroid glands of ewes and fetuses, respectively. Histologically, ninety nine lesions in the ewes and twenty two lesions...

cyclophosphamide (cp) is a mustard alkylating agent used in the treatment of a number of neoplastic diseases and as an immunosuppressant for the prevention of xenograft rejection. there are many reports that the teratogenic effects of cyclophosphamide can be prevented by application of antioxidant drugs and stimulation of the maternal immune system. also, there is some evidence that l-carnitine...
