The transcriptional factor OCT4 regulates pluripotency of stem cells and has an important role during oocyte growth. Whereas, its role has remained ambiguous in ovarian tissue during reproductive cycle. Therefore, this study was aimed to investigate the expression patterns of OCT4 in mouse ovaries during the normal estrous cycle. Adult National Medical Research Institute mice were classified as...

Trehalose is the non-reducing alpha-alpha-1, 1-linked glucose disaccharide. The biosynthesisprecursor of trehalose, trehalose-6-phosphate (T6P), is essential for plant development, growth,carbon utilization and alters photosynthetic capacity but its mode of action is not understood. In thecurrent research, 6 days old seedlings of Arabidopsis thaliana (Columbia ecotype) were grown inliquid cultu...

channel activities, particularly those of calcium channels, have vital roles in the process of sperm maturation, motility and sperm-egg interaction. a group of the recently discovered ion channels associated with these processes is four novel channel-like proteins known as catsper (cation channel sperm) gene family. catsper1 and catsper2 show sperm specific expression patterns. however, neither...

expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...
