Scleractinian coral morphogenesis : searching for stem cells and precursors of the skeletogenic calicodermis

Metamorphosis is a crucial step in the life cycle of a scleractinian coral: The swimming coral larva, the planula, settles, and metamorphoses into a sessile calcifying primary polyp, which subsequently grows into an adult colony. Importantly, morphogenesis ...

Reconciliation of classification systems defining molecular subtypes of colorectal cancer

Douglas Hanahan, Anguraj Sadanandam, Xin Wang

Recently we published two independent studies describing novel gene expression-based classifications of colorectal cancer (CRC). Notably, each study stratified CRC into a different number of subtypes: one reported 3 subtypes, whereas the second highlighted ...

The in situ light microenvironment of corals

Michael Kühl

We used a novel diver-operated microsensor system to collect in situ spectrally resolved light fields on corals with a micrometer spatial resolution. The light microenvironment differed between polyp and coenosarc tissues with scalar irradiance (400-700 nm ...

A colorectal cancer classification system that associates cellular phenotype and responses to therapy

Douglas Hanahan, Krisztian Homicsko, Anguraj Sadanandam, Stephan Wullschleger

Colorectal cancer (CRC) is a major cause of cancer mortality. Whereas some patients respond well to therapy, others do not, and thus more precise, individualized treatment strategies are needed. To that end, we analyzed gene expression profiles from 1,290 ...

β-catenin represses expression of the tumour suppressor 15-prostaglandin dehydrogenase in the normal intestinal epithelium and colorectal tumour cells

Jörg Hülsken, Paloma Ordonez Moran

BACKGROUND: Cyclooxygenase-2 (COX-2) overexpression in colorectal cancer increases levels of its pro-tumorigenic product prostaglandin E2 (PGE(2)). The recently identified colorectal tumour suppressor 15-prostaglandin dehydrogenase (15-PGDH) catalyses pros ...

The Intestinal Nuclear Receptor Signature With Epithelial Localization Patterns and Expression Modulation in Tumors

Johan Auwerx, Kristina Schoonjans

BACKGROUND & AIMS: The WNT-adenomatous polyposis coli system controls cell fate in the intestinal epithelium, where compartment-specific genes tightly regulate proliferation, migration, and differentiation. Nuclear receptors are transcription factors funct ...

Abnormal fear conditioning and amygdala processing in an animal model of autism

Maria del Carmen Sandi Perez, Henry Markram, Deborah La Mendola, Kamila Markram, Tania Rinaldi

A core feature of autism spectrum disorders is the impairment in social interactions. Among other brain regions, a deficit in amygdala processing has been suggested to underlie this impairment, but whether the amygdala is processing fear abnormally in auti ...

Notch/gamma-secretase inhibition turns proliferative cells in intestinal crypts and adenomas into goblet cells

Freddy Radtke

The self-renewing epithelium of the small intestine is ordered into stem/progenitor crypt compartments and differentiated villus compartments. Recent evidence indicates that the Wnt cascade is the dominant force in controlling cell fate along the crypt-vil ...
