Input: Consider Input: Chromatin immunoprecipitation assays have contributed greatly to our understanding of the role of histone modifications in gene regulation. However, they do not permit analysis with single-cell resolution, thus confounding analyses of heterogeneous cell populations. Here we present a method that permits visualization of histone modifications of single genomic loci with single-cell resolution in formaldehyde-fixed paraffin-embedded tissue sections based on combined use of in situ hybridization and proximity ligation assays. We show that dimethylation of lysine 4 of histone H3 (H3K4me2) at the MYH11 locus is restricted to the smooth muscle cell (SMC) lineage in human and mouse tissue sections and that the mark persists even in phenotypically modulated SMC in atherosclerotic lesions that show no detectable expression of SMC marker genes. This methodology has promise for broad applications in the study of epigenetic mechanisms in complex multicellular tissues in development and disease.

Input: Consider Input: Oncogene-induced senescence (OIS) is crucial for tumour suppression. Senescent cells implement a complex pro-inflammatory response termed the senescence-associated secretory phenotype (SASP). The SASP reinforces senescence, activates immune surveillance and paradoxically also has pro-tumorigenic properties. Here, we present evidence that the SASP can also induce paracrine senescence in normal cells both in culture and in human and mouse models of OIS in vivo. Coupling quantitative proteomics with small-molecule screens, we identified multiple SASP components mediating paracrine senescence, including TGF- family ligands, VEGF, CCL2 and CCL20. Amongst them, TGF- ligands play a major role by regulating p15(INK4b) and p21(CIP1). Expression of the SASP is controlled by inflammasome-mediated IL-1 signalling. The inflammasome and IL-1 signalling are activated in senescent cells and IL-1 expression can reproduce SASP activation, resulting in senescence. Our results demonstrate that the SASP can cause paracrine senescence and impact on tumour suppression and senescence in vivo.

Output: A complex secretory program orchestrated by the inflammasome controls paracrine senescence

Input: Consider Input: Previous studies with undergraduates have provided support for the reliability and oblique three-factor structure of a new scale, the Pain Catastrophizing Scale (PCS). We examined the reliability and validity of the PCS in adult community and pain outpatient samples. The PCS showed a high internal consistency in both groups. Using data from the community sample, confirmatory factor analyses showed that the PCS taps a single construct characterized by three related dimensions. Gender differences were obtained on the PCS total score in the community and the outpatient samples. The analyses also showed significant differences between the community and the outpatient samples on the PCS total and subscales. Overall, the results showed strong evidence of criterion-related, concurrent, and discriminant validity for the PCS in the community sample. Limitations of the present study are discussed.
