A miR-375/YAP axis regulates neuroendocrine differentiation and tumorigenesis in lung carcinoid cells

Iacovos Michael, Mohammad Sadegh Saghafinia

Lung carcinoids are variably aggressive and mechanistically understudied neuroendocrine neoplasms (NENs). Here, we identified and elucidated the function of a miR-375/yes-associated protein (YAP) axis in lung carcinoid (H727) cells. miR-375 and YAP are res ...

A Machine-Generated View of the Role of Blood Glucose Levels in the Severity of COVID-19

Henry Markram, Daniel Keller, Jay Coggan, Mohameth François Sy, Cyrille Pierre Henri Favreau, Anna-Kristin Kaufmann, Emmanuelle Logette, Francesco Casalegno, Samuel Claude Kerrien, Enrico Scantamburlo, Charlotte Lorin, Marine Laure Bertschy, Pierre-Alexandre Fonta, Jan Krepl, Emilie Delattre, Caitlin Claire Monney, Stanislav Schmidt

SARS-CoV-2 started spreading toward the end of 2019 causing COVID-19, a disease that reached pandemic proportions among the human population within months. The reasons for the spectrum of differences in the severity of the disease across the population, an ...

Expression of Prox1 in Medullary Thyroid Carcinoma Is Associated with Chromogranin A and Calcitonin Expression and with Ki67 Proliferative Index, but Not with Prognosis

Medullary thyroid carcinoma (MTC) has been shown to express Prospero homeobox protein 1 (Prox1), a transcription factor whose expression is altered in a variety of human cancers. We conducted a retrospective study on a series of 32 patients with MTC to tes ...

Enhancers of notch signaling and their use in the treatment of cancers and malignancies medicable by upregulation of notch

Jieping Zhu, Viktoria Reinmüller

The present invention relates to the use for enhancing Notch signaling in an individual, of a compound showing the general formula (I) and/or a pharmaceutically acceptable salt or ester thereof, for the treatment of a disease selected from the group of der ...

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 ...

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 ...

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 ...

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

Mutations in Bicaudal C1 (BICC1), an RNA binding protein involved in translational regulation, have been associated with cystic kidney disease both in humans and in mice. Since kidney cysts associate with pancreatic defects in several human syndromes, we i ...

The Receptor TGR5 Mediates the Prokinetic Actions of Intestinal Bile Acids and Is Required for Normal Defecation in Mice

Kristina Schoonjans

BACKGROUND & AIMS: Abnormal delivery of bile acids (BAs) to the colon as a result of disease or therapy causes constipation or diarrhea by unknown mechanisms. The G protein-coupled BA receptor TGR5 (or GPBAR1) is expressed by enteric neurons and endocrine ...

Planar Cell Polarity Controls Pancreatic Beta Cell Differentiation and Glucose Homeostasis

Anne Grapin-Botton, Cédric Cortijo

Planar cell polarity (PCP) refers to the collective orientation of cells within the epithelial plane. We show that progenitor cells forming the ducts of the embryonic pancreas express PCP proteins and exhibit an active PCP pathway. Planar polarity proteins ...

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 ...

Neurogenin3 Initiates Stepwise Delamination of Differentiating Endocrine Cells During Pancreas Development

Anne Grapin-Botton, Yung Hae Kim, Keiichi Katsumoto

During development, pancreatic endocrine cells are specified within the pancreatic epithelium. They subsequently delaminate out of the epithelium and cluster in the mesenchyme to form the islets of Langerhans. Neurogenin3 (Ngn3) is a transcription factor r ...

Definition of in Vitro Microenvironments to Characterize and Control Pancreatic Progenitor Expansion and Differentiation

Chiara Greggio

The pancreas plays a central role in metabolism. The exocrine pancreas, composed of ductal and acinar cells, secretes and delivers digestive enzymes into the duodenum where they contribute to food digestion. The endocrine pancreas, constituted by the islet ...

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 ...

Two distinct mechanisms target GAD67 to vesicular pathways and presynaptic clusters

Steinunn Baekkeskov Hanahan

T he inhibitory neurotransmitter gamma-amino butyric acid (GABA) is synthesized by two isoforms of the enzyme glutamic acid decarboxylase (GAD): GAD65 and GAD67. Whereas GAD67 is constitutively active and produces >90% of GABA in the central nervous system ...

Wnt Signaling in Pancreas Development and Cancer

Marine Marie Kraus

During early somite stages of development, the broad endoderm-derived foregut and hindgut territories become further subdivided along the antero-posterior axis into organs. One of these organs is the pancreas which serves two major physiological functions: ...

Fetal cells for intervertebral disc regeneration

Degeneration of the intervertebral disc (IVD) is thought to be one main factor in the development of back pain. It is not a symptom by itself but can lead to painful pathological conditions. Current treatments aim at relieving pain by conservative care, me ...

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 ...

Temporal control of neurogenin3 activity in pancreas progenitors reveals competence windows for the generation of different endocrine cell types

Friedrich Beermann, Anne Grapin-Botton

All pancreatic endocrine cells, producing glucagon, insulin, somatostatin, or PP, differentiate from Pdx1+ progenitors that transiently express Neurogenin3. To understand whether the competence of pancreatic progenitors changes over time, we generated tran ...

Pancreas development and cancer - Wnt/beta-catenin at issue

Anne Grapin-Botton

beta-catenin and Adenomatous poliposis coli (APC) have been implicated in non-ductal pancreatic cancers. As for many other organs, several recent publications show that beta-catenin and more largely the Wnt pathway appear to function at the level of pancre ...
