Little is known about the effects of hypoxic ischemic (HI) injury on these critical postnatal processes.
Pre- and postnatal processes contribute to the lifelong responsiveness of the HPA axis to stressors.
These findings indicate that developmental and postnatal processes may have many similarities but can be different at the molecular level.
Their pleiotropic effects on different cell types steer many pre- and postnatal processes, such as cell differentiation, proliferation, adhesion, motility, and apoptosis [ 9- 11].
IGF-1 is involved in a number of postnatal processes affected by early life events, including IR, obesity, and chronic lung disease.
Postnatal processes are also divided into two stages (Ι Ι Ι and ΙV) and genes expression profile of stage ΙV (ranging from day 7 to week 18) exhibited more invariant property [ 4].
We demonstrate that female offspring of high-fat/high-sugar diet-fed dams are particularly vulnerable to metabolic perturbation with body weight increases due to postnatal processes, whereas in utero effects of the diet ultimately lead to glucose homeostasis dysregulation.
We further identify the developmentally critical time periods during which maternal diet influences aspects of offspring metabolic balance; whereas increased weight gain is programmed by postnatal processes, disturbances in the maintenance of offspring glucose homeostasis are a consequence of in utero effects.
The results of this postnatal developmental process provide critical support for neonatal mammals, and maternal investment in this process is critical for the survival of the species.
In the pig, for example, the number of muscle fibers is prenatally determined during primary and secondary muscle fiber formation, while the postnatal hypertrophy process then increases the length and diameter of these fibers.
