Abstract Study question Are S-sulfenylation and S-nitrosylation, two essential posttranslational modifications (PTMs), increased during sperm capacitation? Which proteins are subjected to S-sulfenylation? Summary answer S-nitrosylation increase capacitation. affects certain proteins, including A-kinase anchor protein 13, Fibrilline-1, Spermatogenesis-associated 7. What is known already There a ...

Background The present study was designed to evaluate the survival and proliferation of spermatogonial stem cells from cryptorchid mouse testis in co-culture system over a 3 weeks period. MaterialsAndMethods Sertoli and spermatogonial cells were isolated from bilateral cryptorchid mouse model testes. Isolated spermatogonial cells were co-cultured with Sertoli cells in minimal essential medium (...

Background: There is a direct correlation between ocular vascular endothelial growth factor (VEGF) level and progression of pathological outcomes in diabetic retinopathy. In our previous study, the periocular administration of propranolol and celecoxib could significantly reduce ocular VEGF levels in a diabetic mouse model. Here, we investigated the changes of serum VEGF after ...

OBJECTIVE Mitogen-activated protein kinase phosphatase-1 (MKP-1) is one of several oxidized-l-alpha-1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine (Ox-PAPC)-induced genes identified in human aortic endothelial cells (HAEC). We previously reported that MKP-1 activity is required for Ox-PAPC-mediated endothelial/monocyte interactions; however, an in vivo role of MKP-1 in atherogenesis ...

Background DOX is a powerful chemotherapeutic agent used in the treatment of solid tumors and malignant hematological diseases. However, its cardiac toxicity limits the clinical usefulness of this drug. Previous reports have shown Corticosteroids induce a cytoprotective effect on cardiomyocytes. Mouse transgenic embryonic stem cell-derived pure cardiomyocytes may be considered as a model for a...

The ectopic deposition of fat in liver and muscle during obesity is well established, however surprisingly little is known about the intestine. We used the ob/ob mouse and C57BL6/J mice fed a high fat (HF) diet to examine the effects of obesity and the effects of HF feeding, respectively, on intestinal mucosal triacylglycerol (TG) accumulation. Male C57BL6/J (wild-type, WT) mice were fed low fa...

Somatic cell reprogramming has generated enormous interest after the first report by Yamanaka and his coworkers in 2006 on the generation of induced pluripotent stem cells (iPSCs) from mouse fibroblasts. Here we report the generation of stable iPSCs from mouse fibroblasts by recombinant protein transduction (Klf4, Oct4, Sox2, and c-Myc), a procedure designed to circumvent the risks caused by in...
