Description
Resistance towards anti-angiogenic therapy (AAT) still represents a substantial clinical challenge. We report here that tumor-infiltrating mast cells (MC) are powerful mediators decreasing efficacy of AAT in mice and cancer patients. They act in a cell-extrinsic manner by secreting granzyme B, which liberates pro-angiogenic mediators from the extracellular matrix. In addition, MC also diminish efficacy of anti-angiogenic agents in a cell-autonomous way, which can be blocked by the mast cell degranulation inhibitor cromolyn. Our findings are relevant in humans because patients harboring higher numbers of MC in their tumors have an inferior outcome after anti-angiogenic treatment in the Gepar Quinto randomized Phase 3 clinical trial. Thus, MC-targeting might represent a novel promising approach to increase efficacy of AAT.

Description
The Loeys-Dietz syndrome (LDS) is an inherited connective tissue disorder caused by mutations in the transforming growth factor (TGF-) receptors TGFBR1 or TGFBR2. Most patients with LDS develop severe aortic aneurysms resulting in early need of surgical intervention. We investigated circulating outgrowth endothelial cells (OEC) from the peripheral blood of LDS to gain further insight into the pathophysiology of the disorder. We performed gene expression profiling using microarray analysis followed by quantitative PCR for verification of gene expression. OECs isolated from age- and sex-matched healthy donors served as reference control.

Description
Noroviruses have been widely recognized for their importance as causative agents of non-bacterial gastroenteritis. Mouse norovirus is the only representative of the norovirus genus, family Caliciviridae, able to grow in cell culture. The aim of this study is to describe the differences in the expression profiles of MNV-1 and mock-infected macrophages (RAW 264.7 cells), in order to better understand the response of the host cell to norovirus infection.
Publication Title
Apoptosis in murine norovirus-infected RAW264.7 cells is associated with downregulation of survivin.

Description
The cochlear duct is tonotopically organized, such that the basal cochlea responds more sensitively to high frequency sounds and the apical cochlea to low frequency sounds. In effort to understand how the tonotopic organization is established in mammals, we searched for genes that are differentially expressed along the tonotopic axis during neonatal development.
Publication Title
Developmental gene expression profiling along the tonotopic axis of the mouse cochlea.

Description
Biallelic mutations of the DNA annealing helicase SMARCAL1 (SWI/SNF-related matrix-associated actin-dependent regulator of chromatin, subfamily a-like 1) cause Schimke immuno-osseous dysplasia (SIOD, MIM 242900), an incompletely penetrant autosomal recessive disorder. Using human, Drosophila, and mouse models, we show that the proteins encoded by SMARCAL1 orthologues localize to transcriptionally active chromatin and modulate gene expression. We also show that similar to SIOD patients, deficiency of the SMARCAL1 orthologues alone is insufficient to cause disease in fruit flies and mice although such deficiency causes modest diffuse alterations in gene expression. Rather, disease manifests when SMARCAL1 deficiency interacts with genetic and environmental factors that further alter gene expression. We conclude that the SMARCAL1 annealing helicase buffers fluctuations in gene expression and that alterations in gene expression contribute to the penetrance of SIOD.

Overall design: The RNA sequencing libraries were constructed from the liver RNA of 3-4-month Smarcal1del/del and wt female mice (n=3/group) at 20°C and after 1 hour at 39.5°C. These libraries were sequenced using the whole transcriptome shotgun sequencing procedure.
