The endocrine system dynamically controls tissue differentiation and homeostasis, but has not been studied using dynamic tissue culture paradigms. Here we show that a microfluidic system supports murine ovarian follicles to produce the human 28-day menstrual cycle hormone profile, which controls human female reproductive tract and peripheral tissue dynamics in single, dual and multiple unit mic...
The genetic basis of size variation in the reproductive organs of tomatillo (Physalis philadelphica) is unknown. Here we report that the expression levels of the gene Physalis Organ Size 1 (POS1) are positively associated with size variation in P. philadelphica reproductive organs such flowers, berries and seeds. POS1 knockdown results in smaller flowers and berries with smaller cells as compar...
Broad-scale evolutionary comparisons have shown that branching forms arose by convergence in vascular plants and bryophytes, but the trajectory of branching form diversification in bryophytes is unclear. Mosses are the most species-rich bryophyte lineage and two sub-groups are circumscribed by alternative reproductive organ placements. In one, reproductive organs form apically, terminating grow...
In 3 trials, the effects of dietary supplementation with phytase (PHY) and 25-hydroxycholecalciferol (25-D3) on the digestive and reproductive organ characteristics of commercial layers that were inoculated prelay (12 wk of age) or at the onset of lay (22 wk of age) with F-strain Mycoplasma gallisepticum (FMG) were assessed at 58 wk of age. Experimental layer diets that included a basal control...
Female reproductive organs are mainly regulated by estrogen and progesterone. Specifically, the uterus, vagina and mammary gland show organ-specific mitosis and morphological changes during proliferative events, such as estrous cycle, gestation and lactation. The mechanism underlying these organ-specific estrogen-dependent events is still unknown. We examined, therefore, global gene expression ...
Polycystic ovary syndrome (PCOS) is a complex, but relatively common endocrine disorder associated with chronic anovulation, hyperandrogenism, and micro-polycystic ovaries. In addition to reduced fertility, people PCOS have higher risk of obesity, insulin resistance, metabolic disease, all comorbidities that are mitochondrial dysfunction. This review summarizes human animal data report dysfunct...
The evolution of morphological characters is mediated by the evolution of developmental genes. Evolutionary changes can either affect cis-regulatory elements, leading to differences in their temporal and spatial regulation, or affect the coding region. Although there is ample evidence for the importance of cis-regulatory evolution, it has only recently been shown that transcription factors do n...
