“…Cell proliferation and differentiation is a simultaneous and contradictory biological process. cAMP serves an important role in the regulation of these contradictions (41,42). To clarify how CD38 affects the concentration of cAMP in NPC cells, cAMP was tested and it was determined that the concentration of cAMP in 5-8F/CD38 cells was 60.25±3.23 ng/ml, and the 5-8F/Vector intracellular cAMP concentration was 53.48±2.49 ng/ml.…”

“…Insulin also induces GVBD in denuded (devoid of surrounding follicular cells) zebrafish oocytes, suggesting that insulin can mediate oocyte maturation via a pathway independent of steroids in teleosts as well (Das, Khan, & Maitra, ). Both insr and igf1r are also expressed by zebrafish and carp oocytes, and expression of insr is lower than that of igf1r (reviewed by Das et al, ). Zebrafish mid‐vitellogenic follicle‐enclosed oocytes (Figure b) respond to insulin, but not human chorionic gonadotropin, suggesting that oocytes are only responsive to insulin at an early stage of development (Das et al, ).…”

“…Insulin likely triggers meiotic resumption by up‐regulating membrane abundance of Progesterone receptor α and 20β‐hydroxy‐steroid dehydrogenase, which is responsible for maturation‐inducing steroid synthesis (Das et al, ). In vitro insulin stimulation can also trigger igf3 expression in zebrafish follicle‐enclosed oocytes (Das et al, ), suggesting an important role for insulin in modulating the activity of local paracrine factors involved in oocyte maturation (Das et al, ).…”
