Single-cell transcriptome dynamics in stabilized pituitary gonadotrope cells [smartseq_pituitary]

ABSTRACT: Studying dynamic transcripts in single cells (SC) requires large numbers of timed samples. We report an easy to use protocol to stabilize RNA in intact SCs without perturbing transcriptional patterns, and demonstrate its applicability for SC transcriptome assays with cells and tissue. We identify a gene-specific hierarchical pattern of all-or-none transcript induction elicited by different concentrations of pulsatile hormone stimuli in pituitary gonadotropes.

Steroidogenic factor 1 regulates transcription of the inhibin B co-receptor in pituitary gonadotrope cells

Project description:The inhibins control reproduction by suppressing follicle-stimulating hormone synthesis by pituitary gonadotrope cells. The recently discovered inhibin B co-receptor mediating this inhibition, TGFBR3L, is selectively and highly expressed in gonadotropes in both mice and humans. We sought to characterize mechanisms controlling cell-specific Tgfbr3l/TGFBR3L transcription. We identified two steroidogenic factor 1 (SF-1) cis-elements in the proximal Tgfbr3l promoter in mice. Using single-nucleus ATAC-seq we find that gonadotrope-specific SF-1 (Nr5a1) knockout mice, which exhibit hypogonadotropic hypogonadism, display, contrary to controls, closed chromatin in the promoter region of theTgfbr3l gene in gonadotropes. These, and other, data collectively indicate that SF-1 directly regulates Tgfbr3l/TGFBR3L transcription, contributing to gonadotrope-specific expression of the gene.

Most adult gonadotrophs originate from postnatal pituitary stem cells during minipuberty.

Project description:In the first three weeks postnatally, the pituitary gland undergoes a period of rapid growth, due to both cell proliferation and endocrine cell size increase. SCs are initially the most proliferative, and lineage tracing experiments previously showed that neonatal SCs can give rise to all endocrine cell types. However, because the Cre drivers used for lineage tracing were relatively inefficient and relied on tamoxifen, a selective estrogen receptor modulator which perturbs normal physiology, we could not decipher SC contribution to organ growth. We have thus performed lineage tracing using a new, more efficient and physiologically neutral Sox2rtTA allele. When we traced early postnatal SCs using Sox2rtTA, we observed, similarly in both sexes, that most adult gonadotrophs derive from this neonatal SC population. These observations were confirmed and complemented by a single cell RNAseq dataset from postnatal day 3 (PND3) SOX9iresGFP XX and XY positive cells. From SOX9iresGFP cells, which comprise SCs and their immediate progeny, cell trajectories were inferred, and relevant gene regulatory networks predicted. Along with lineage tracing experiments, this dataset confirmed that SCs mostly differentiate into gonadotrophs postnatally. As animals develop, SC-derived gonadotrophs invade the gland, while the minor embryonic population remains confined ventrally. The discovery of a dual origin for gonadotrophs may help understand aspects of gonadotrophin regulation and mechanisms of diseases affecting puberty and fertility.

Transcriptome of the NR5A1 expressing pituitary gonadotropes

Project description:NR5A1 is expressed in the pituitary gonadotropes and regulates their functional differentiation. In this study, transcriptomes of the pituitary gonadotropes which are sorted from Ad4BP-BAC-EGFP mice were revealed in males and females.

Schwann cell plasticity regulates neuroblastic tumor cell differentiation - phosphoproteomics

Project description:The remarkable plasticity of Schwann cells (SCs) is essential for nerve regeneration but also contributes to neuropathies and cancer progression. It has not yet been investigated whether the adaptive potential of SCs is manifested in stromal, tumor associated SCs characteristically found within a benign subtype of neuroblastic tumors (NBTs). We here performed transcriptome profiling of human NBTs, rich and poor in SC stroma, as well as human injured nerves, rich in repair SCs, revealing that stromal SCs exhibit a repair SC characteristic gene expression signature. In turn, primary repair SCs had a pro-differentiating and anti-proliferative effect on NBT cell lines after direct and trans-well co-culture. Within the pool of secreted stromal/repair SC factors, we identified EGFL8, a matricellular protein with so far undescribed function, to induce neuronal differentiation of aggressive NBT cells. EGFL8 expression further correlated with favorable tumor stage and increased patient survival. Our findings suggest that stromal SCs exert nerve repair associated functions in the tumor-environment and underline the therapeutic value of SC-derived factors for aggressive, SC stroma-poor NBTs.
