Project description:The organs of female animals can be dramatically enlarged and metabolically remodelled by reproduction. The cellular changes and genetic programmes that initiate and sustain these transformations remain largely uncharacterised. It is also unclear whether the mechanisms that drive reproductive growth are shared between organs, or with other environmental triggers of adult organ growth. We have tackled these questions in mouse mothers, whose intestines provide a striking and genetically tractable example of reproductive organ resizing. We find that intestinal remodelling during reproduction is anticipatory of reproductive needs and distinct from diet-induced intestinal resizing.

Project description:The organs of many female animals grow and are metabolically remodelled by reproduction; this process has been historically overlooked. Using the intestine of mouse mothers, a striking and genetically tractable example of reproductive organ resizing, we find that reproductive intestinal remodelling is anticipatory and distinct from diet- or microbiota-induced intestinal resizing. Reproductive remodelling involves partially irreversible elongation of the intestine and fully reversible growth of its epithelium, which ensues from an expansion of the isthmus progenitors, increased progenitor proliferation and accelerated migration of differentiated cells. Through spatiotemporal analysis of gene expression, we identify induction of the SGLT3a transporter in a subset of enterocytes as one of the earliest reproductive hallmarks within the intestinal epithelium. Electrophysiological and genetic interrogations in vivo and in organoids indicate that SGLT3a does not sustain broad digestive functions or enterocyte health. Instead, SGLT3a detects protons and sodium to extrinsically support the expansion of adjacent Fgfbp1-positive isthmus progenitors and gut epithelial growth during reproduction. Our findings reveal unanticipated molecular, cell and organ specificity to physiological organ remodelling, raising the possibility that organ- and state-specific growth programmes could be leveraged to improve pregnancy outcomes or prevent maladaptive consequences of such growth.

Project description:Post-developmental organ resizing improves organismal fitness under constantly changing nutrient environments. Although stem cell abundance is a fundamental determinant of adaptive resizing, our understanding of its underlying mechanisms remains primarily limited to the regulation of stem cell division. Here, we demonstrate that nutrient fluctuation induces dedifferentiation in the Drosophila adult midgut to drive adaptive intestinal growth. From lineage tracing and single-cell RNA sequencing, we identify a subpopulation of enteroendocrine (EE) cells that convert into functional intestinal stem cells (ISCs) in response to dietary glucose and amino acids by activating the JAK-STAT pathway. Genetic ablation of EE-derived ISCs severely impairs ISC expansion and midgut growth despite the retention of resident ISCs, and in silico modeling further indicates that EE dedifferentiation enables an efficient increase in the midgut cell number while maintaining epithelial cell composition. Our findings identify a physiologically induced dedifferentiation that ensures ISC expansion during adaptive organ growth in concert with nutrient conditions.

Project description:Estrogen induce organ-specific cell proliferation and development in female reproductive organs, though the reproductive differentiation, sex maturation, implantation and lactation. However, the mechanism of organ-specific estrogen responsive genes is unknown. Thus, we examined early estrogen responsive genes in mouse uterus, vagina and mammary gland. Keywords: organ specificity

Project description:Gene expression throughout the reproductive process in rice (Oryza sativa) beginning with primordia development through pollination/fertilization to zygote formation was analyzed. We analyzed 25 stages/organs of rice reproductive development including early microsporogenesis stages with 57,381 probe sets, and identified around 26,000 expressed probe sets in each stage. Fine dissection of 25 reproductive stages/organs combined with detailed microarray profiling revealed dramatic, coordinated and finely tuned changes in gene expression. Decrease of expressed genes in the pollen maturation process was observed in a similar way with Arabidopsis and maize. An almost equal number of ab initio predicted genes and cloned genes appeared or disappeared coordinated with developmental stage progression. A large number of organ-/stage-specific genes were identified; notably 2,593 probe sets for developing anther, including 932 probe sets corresponding to ab initio predicted genes. Analysis of cell cycle-related genes revealed that several CDKs, cyclins and components of SCF E3 ubiquitin ligase complexes were expressed specifically in reproductive organs. Cell wall biosynthesis or degradation protein genes and transcription factor genes expressed specifically in reproductive stages were also newly identified. Rice genes homologous to reproduction-related genes in other plants showed expression profiles both consistent and inconsistent with their predicted functions. The rice reproductive expression atlas is likely to be the deepest and most comprehensive dataset available, indispensable for unraveling functions of many specific genes in plant reproductive processes that have not yet been thoroughly analyzed. Keywords: developmental stage comparison, tissue comparison Regenerating calli on agar plate, young leaves and roots grown in a green house, shoots grown in growth chamber were collected as references of reproductive samples. Three or four biological replicates at each stage were analyzed with Affymetrix Rice Genome Array, and total number of samples in this series is 25.
