[Q]: Syndromic forms of osteosarcoma (OS) account for less than 10% of all recorded cases of this malignancy. An individual OS predisposition is also possible by the inheritance of low penetrance alleles of tumor susceptibility genes, usually without evidence of a syndromic condition. Genetic variants involved in such a non-syndromic form of tumor predisposition are difficult to identify, given the low incidence of osteosarcoma cases and the genetic heterogeneity of patients. We recently mapped a major OS susceptibility QTL to mouse chromosome 14 by comparing alpha-radiation induced osteosarcoma in mouse strains which differ in their tumor susceptibility.', 'Tumor-specific allelic losses in murine osteosacoma were mapped along chromosome 14 using microsatellite markers and SNP allelotyping. Candidate gene search in the mapped interval was refined using PosMed data mining and mRNA expression analysis in normal osteoblasts. A strain-specific promoter variant in Rb1 was tested for its influence on mRNA expression using reporter assay.', 'A common Rb1 allele derived from the BALB/cHeNhg strain was identified as the major determinant of radiation-induced OS risk at this locus. Increased OS-risk is linked with a hexanucleotide deletion in the promoter region which is predicted to change WT1 and SP1 transcription factor-binding sites. Both in-vitro reporter and in-vivo expression assays confirmed an approx. 1.5 fold reduced gene expression by this promoter variant. Concordantly, the 50% reduction in Rb1 expression in mice bearing a conditional hemizygous Rb1 deletion causes a significant rise of OS incidence following alpha-irradiation.

[Q]: Cullin1 is a scaffold protein of the ubiquitin E3 ligase Skp1/Cullin1/Rbx1/F-box protein complex which ubiquitinates a broad range of proteins participating in biochemical events like cell-cycle progression, signal transduction, and transcription. Cullin1 is involved in the progression of several cancers, such as melanoma, breast cancer, and gastric cancer.', "To investigate the role of Cullin1 in the development of non-small-cell lung cancer (NSCLC), we examined the expression of Cullin1 in 8-paired fresh NSCLC tissues. We then constructed immunohistochemistry (IHC) on 114 paraffin-embedded slices and evaluated the correlation between Cullin1 expression and clinicopathologic variables, as well as patients' overall survival.", "We found that Cullin1 was highly expressed in NSCLC tissues and significantly associated with NSCLC's histological differentiation (P=0.002), clinical stage (P=0.010) and Ki-67 (P=0.021). Furthermore, we showed a strong correlation between high Cullin1 expression and worse overall survival rates in NSCLC patients (P<0.001). Cox regression analysis revealed that Cullin1 expression was an independent prognostic factor to predict 5-year patient outcome in NSCLC cancer (P=0.033).

[Q]: Churg-Strauss syndrome (CSS) and hypereosinophilic syndrome (HES) overlap considerably in clinical presentation. A reliable means of distinguishing between these groups of patients is needed, especially in the setting of glucocorticoid therapy.', 'A retrospective chart review of 276 adult subjects referred for evaluation of eosinophilia > 1500/l was performed, and subjects with a documented secondary cause of eosinophilia or a PDGFR -positive myeloproliferative neoplasm were excluded. The remaining subjects were assessed for the presence of American College of Rheumatology (ACR) criteria. Laboratory and clinical parameters were compared between subjects with biopsy-proven vasculitis (CSS; n = 8), 4 ACR criteria (probable CSS; n = 21), HES with asthma and/or sinusitis without other CSS-defining criteria (HESwAS; n = 20), HES without asthma or sinusitis (HES; n = 18), and normal controls (n = 8). Serum biomarkers reported to be associated with CSS were measured using standard techniques.', 'There were no differences between the subjects with definite or probable CSS or HES with respect to age, gender, or maintenance steroid dose. Serum CCL17, IL-8, and eotaxin levels were significantly increased in eosinophilic subjects as compared to normal controls, but were similar between the eosinophilic groups. Serum CCL17 correlated with eosinophil count (P < 0.0001, r = 0.73), but not with prednisone dose.
