Abstract

Mammalian physiology is governed by a complex circadian timing system that involves interacting positive and negative transcriptional feedback loops. A key role in this feedback loop was attributed to the PAS domain helix-loop-helix protein CLOCK, on the basis of a dominant-negative mutation in this transcription factor. However, recent experiments by Reppert and coworkers with Clock knockout mice suggest that CLOCK is dispensable for rhythmic gene expression and behavior, presumably because other proteins can substitute for CLOCK in these animals.

Antitumor activity of ALK1 in pancreatic carcinoma cells.

In this study, the authors investigated the expression of activin receptor-like kinase 1 (ALK1) in pancreatic carcinoma and evaluated its potential role as a tumor suppressor in vitro and in vivo. Endogenous ALK1 expression was demonstrated by immunohistochemistry in both pancreatic tumor tissue and peritumoral normal tissue from 6 patients and by RT-PCR in 8/12 established pancreatic cancer cell lines. Ectopic expression of a constitutively active (ca) ALK1 mutant in TGF-beta sensitive PANC-1 and COLO-357 cells augmented transcriptional activation of a Smad2/3 responsive reporter, and slowed down basal growth in vitro. Both effects were further enhanced by TGF-beta/ALK5 stimulation, suggesting largely independent nuclear Smad signaling by both type I receptors. Upon orthotopic transplantation of PANC-1-caALK1 into immunodeficient mice, tumor size was strongly reduced and was associated with a lower microvessel density in the PANC-1-caALK1-derived tumors. In vitro, this mutant efficiently blocked TGF-beta-induced epithelial-to-mesenchymal transdifferentiation and suppressed TGF-beta/ALK5-mediated activation of the p38 MAPK pathway. Mechanistically, caALK1 silenced MyD118, an immediate TGF-beta target gene whose protein product, GADD45beta, couples Smad signaling to p38 activation. These results show that ALK1 activation in pancreatic tumor cells is antioncogenic by inducing ALK5-independent growth inhibition and by blocking TGF-beta/ALK5-mediated epithelial-to-mesenchymal transdifferentiation and, possibly, invasion and metastatic progression.

Postnatal induction of transforming growth factor beta signaling in fibroblasts of mice recapitulates clinical, histologic, and biochemical features of scleroderma.

OBJECTIVE: Increased signaling by transforming growth factor beta (TGFbeta) has been implicated in systemic sclerosis (SSc; scleroderma), a complex disorder of connective tissues characterized by excessive accumulation of collagen and other extracellular matrix components in systemic organs. To directly assess the effect of sustained TGFbeta signaling in SSc, we established a novel mouse model in which the TGFbeta signaling pathway is activated in fibroblasts postnatally. METHODS: The mice we used (termed TBR1(CA); Cre-ER mice) harbor both the DNA for an inducible constitutively active TGFbeta receptor I (TGFbetaRI) mutation, which has been targeted to the ROSA locus, and a Cre-ER transgene that is driven by a fibroblast-specific promoter. Administration of 4-hydroxytamoxifen 2 weeks after birth activates the expression of constitutively active TGFbetaRI. RESULTS: These mice recapitulated clinical, histologic, and biochemical features of human SSc, showing pronounced and generalized fibrosis of the dermis, thinner epidermis, loss of hair follicles, and fibrotic thickening of small blood vessel walls in the lung and kidney. Primary skin fibroblasts from these mice showed elevated expression of downstream TGFbeta targets, reproducing the hallmark biochemical phenotype of explanted SSc dermal fibroblasts. The mouse fibroblasts also showed elevated basal expression of the TGFbeta-regulated promoters plasminogen activator inhibitor 1 and 3TP, increased Smad2/3 phosphorylation, and enhanced myofibroblast differentiation. CONCLUSION: Constitutive activation of TGFbeta signaling in fibroblastic cells of mice after birth caused a marked fibrotic phenotype characteristic of SSc. These mice should be excellent models with which to test therapies aimed at correcting excessive TGFbeta signaling in human scleroderma.

BMP type I receptor ALK2 is essential for proper patterning at late gastrulation during mouse embryogenesis.

Bone morphogenetic proteins (BMPs) have multiple functions during vertebrate development. Previously, it was shown that BMP type I receptor ALK2 (also known as ACVRI, ActRI, or ActRIA) was important for normal mouse gastrulation by deleting exon 4 or exon 5 of Alk2. Recently, flanking exon 7 by loxP sites generated a conditional allele for Alk2. To assess whether the deletion of exon 7 causes functional null of ALK2, and does not produce a dominant negative form or a partially functional form of ALK2, we performed a comparative analysis between Alk2 homozygous mutant embryos with an exon 5 deletion (Alk2(Delta5/Delta5)) and embryos with an exon 7 deletion (Alk2(Delta7/Delta7)). Both Alk2(Delta5/Delta5) and Alk2(Delta7/Delta7) mutants showed identical morphological gastrulation defects. Histological examinations and molecular marker analyses revealed identical abnormal gastrulation phenotypes in Alk2(Delta5/Delta5) and Alk2(Delta7/Delta7) mutants. Although Fgf8 was expressed in the primitive streak of Alk2(Delta5/Delta5) and Alk2(Delta7/Delta7) mutants, Brachyury, Wnt3a, and Tbx6 were dramatically downregulated in Alk2(Delta5/Delta5) and Alk2(Delta7/Delta7) mutants. These results indicate that deletion of exon 7 for Alk2 leads to a functionally null mutation in vivo, and Alk2 is crucial for sustaining the proper gastrulation events in early mouse embryogenesis.
