The adipokine NimrodB5 regulates peripheral hematopoiesis in Drosophila

Bruno Lemaitre, Jean Philippe Boquete, Jan Paul Dudzic, Elodie Julie Virginie Ramond, Bianca Marie Petrignani

In animals, growth is regulated by the complex interplay between paracrine and endocrine signals. When food is scarce, tissues compete for nutrients, leading to critical resource allocation and prioritization. Little is known about how the immune system ma ...

Pancreatic α- and β-Cellular Clocks Have Distinct Molecular Properties and Impact on Islet Hormone Secretion and Gene Expression

Michaël Unser, Daniel Sage, Frédéric Bruno Martin Gachon, Cédric Gobet

A critical role of circadian oscillators in orchestrating insulin secretion and islet gene transcription has been demonstrated recently. However, these studies focused on whole islets and did not explore the interplay between α-cell and β-cell clocks. We p ...

A Preclinical Model for ERα-Positive Breast Cancer Points to the Epithelial Microenvironment as Determinant of Luminal Phenotype and Hormone Response

Cathrin Brisken, Georgios Sflomos, Ayyakkannu Ayyanan, Valentina Scabia, Rachel Marcone, Laura Battista, Valérian Charles Robert Dormoy

Seventy-five percent of breast cancers are estrogen receptor α positive (ER(+)). Research on these tumors is hampered by lack of adequate in vivo models; cell line xenografts require non-physiological hormone supplements, and patient-derived xenografts (PD ...

Cell Cycle-Dependent Differentiation Dynamics Balances Growth and Endocrine Differentiation in the Pancreas

Anne Grapin-Botton, Yung Hae Kim

Organogenesis relies on the spatiotemporal balancing of differentiation and proliferation driven by an expanding pool of progenitor cells. In the mouse pancreas, lineage tracing at the population level has shown that the expanding pancreas progenitors can ...

Intra- and interspecific social challenges modulate the levels of an androgen precursor in a seasonally territorial tropical damselfish

Studies on different vertebrate groups have provided evidence that androgen levels in males increase after competitive social interactions during the breeding season, as postulated by the Challenge Hypothesis. However, social modulation of androgen levels ...

REST represses a subset of the pancreatic endocrine differentiation program

Anne Grapin-Botton, Yung Hae Kim

To contribute to devise successful beta-cell differentiation strategies for the cure of Type 1 diabetes we sought to uncover barriers that restrict endocrine fate acquisition by studying the role of the transcriptional repressor REST in the developing panc ...

Identification of the Link Between the Hypothalamo-Pituitary Axis and the Testicular Orphan Nuclear Receptor NR0B2 in Adult Male Mice

Kristina Schoonjans

The small heterodimer partner (SHP, nuclear receptor subfamily 0, group B, member 2; NR0B2) is an atypical nuclear receptor known mainly for its role in bile acid homeostasis in the enterohepatic tract. We previously showed that NR0B2 controls testicular f ...

Bicaudal C1 promotes pancreatic NEUROG3+ endocrine progenitor differentiation and ductal morphogenesis

Jacques Rougemont, Daniel Constam, Anne Grapin-Botton, Joan Goulley, Yung Hae Kim

In human, mutations in bicaudal C1 (BICC1), an RNA binding protein, have been identified in patients with kidney dysplasia. Deletion of Bicc1 in mouse leads to left-right asymmetry randomization and renal cysts. Here, we show that BICC1 is also expressed i ...

The Digestive Tract of Drosophila melanogaster

Bruno Lemaitre

The digestive tract plays a central role in the digestion and absorption of nutrients. Far from being a passive tube, it provides the first line of defense against pathogens and maintains energy homeostasis by exchanging neuronal and endocrine signals with ...

A Notch-dependent molecular circuitry initiates pancreatic endocrine and ductal cell differentiation

Anne Grapin-Botton

In the pancreas, Notch signaling is thought to prevent cell differentiation, thereby maintaining progenitors in an undifferentiated state. Here, we show that Notch renders progenitors competent to differentiate into ductal and endocrine cells by inducing a ...

Detection of neuronal activity and metabolism in a model of dehydration-induced anorexia in rats at 14.1T using manganese-enhanced MRI and 1H MRS

Rolf Gruetter, Nathalie Just

In this study, hypothalamic activation was performed by dehydration-induced anorexia (DIA) and overnight food suppression (OFS) in female rats. The assessment of the hypothalamic response to these challenges by manganese-enhanced MRI showed increased neuro ...

Role of Neurogenin3 in migration of pancreatic endocrine cells during development

The pancreas is one of the major organs of the digestive tract. Its endocrine function, mainly regulating glucose blood level, is achieved by endocrine cells. These cells are organized in clusters, the so-called islets of Langerhans. During development, th ...

Conditional ablation of Notch signaling in pancreatic development

Freddy Radtke

The role of the Notch signaling members Notch1, Notch2 and Rbpj in exocrine pancreatic development is not well defined. We therefore analyzed conditional pancreas-specific Rbpj and combined Notch1/Notch2 knockout mice using Ptf1a(+/Cre(ex1)) mice crossed w ...
