Question: Insulin resistance and hyperglycaemia are common in severe sepsis. Mitochondrial uncoupling protein 2 (UCP2) plays a role in insulin release and sensitivity.', 'To determine if a common, functional polymorphism in the UCP2 gene promoter region (the -866 G/A polymorphism) contributes to the risk of hyperglycaemia in severe sepsis.', 'In the prospective group 120 non-diabetic patients who were carriers of the G allele had significantly higher maximum blood glucose recordings than non-carriers (mean (SD) AA 8.5 (2.2) mmol/l; GA 8.5 (2.4) mmol/l; GG 10.1 (3.1) mmol/l; p = 0.0042) and required significantly more insulin to maintain target blood glucose (p = 0.0007). In the retrospective study 103 non-diabetic patients showed a similar relationship between maximum glucose and UCP genotype (AA 6.8 (2.3) mmol/l; GA 7.8 (2.2) mmol/l; GG 9.2 (2.9) mmol/l; p = 0.0078).

Question: It has been suggested that genes related to Amerindian ancestry account for the high prevalence of gallstone disease (GD) observed in Mexican-Americans. The HLA-B39 is an allele found in higher frequency in Amerindians whereas HLA-B15 is rarely found. The aim of this study was to test the hypothesis that gallstone susceptibility genes are more prevalent in Mexicans with recent Amerindian ancestry.', 'We carried out a prospective case-controlled study. Subjects were divided into those who had stones visible on gallbladder ultrasound (cases), and those whose ultrasounds were negative for gallstones (controls). Body mass index (BMI) was calculated, and serum lipids and lipoprotein, and glucose levels were measured. Class I HLA (HLA-B) typing was performed by PCR amplification of genomic DNA.', 'Of the 1,101 subjects, 146 were classified as subjects with GD (cases) and 955 as subjects without GD (controls). Mean age of the cases was 53.5 +/- 12.5 yr versus 44.78 +/- 12.0 yr for the controls, p= 0.001. A family history of GD was observed in 48% of the cases versus 28.4% of the controls, p= 0.001. HLA-B39 was more frequently increased in GD subjects (0.162), compared with controls (0.063), p= 0.008. The odds ratio of having HLA-B39 was 2.8 and 95% (CI 95%= 1.3-6.3) for GD; HLA-B15 was more frequently increased in controls than in cases.

Question: The molecular basis to overcome therapeutic resistance to treat glioblastoma remains unclear. The anti-apoptotic b cell lymphoma 2 (BCL2) gene is associated with treatment resistance, and is transactivated by the paired box transcription factor 8 (PAX8). In earlier studies, we demonstrated that increased PAX8 expression in glioma cell lines was associated with the expression of telomerase. In this current study, we more extensively explored a role for PAX8 in gliomagenesis.', 'PAX8 expression was measured in 156 gliomas including telomerase-negative tumours, those with the alternative lengthening of telomeres (ALT) mechanism or with a non-defined telomere maintenance mechanism (NDTMM), using immunohistochemistry and quantitative PCR. We also tested the affect of PAX8 knockdown using siRNA in cell lines on cell survival and BCL2 expression.', 'Seventy-two percent of glioblastomas were PAX8-positive (80% telomerase, 73% NDTMM, and 44% ALT). The majority of the low-grade gliomas and normal brain cells were PAX8-negative. The suppression of PAX8 was associated with a reduction in both cell growth and BCL2, suggesting that a reduction in PAX8 expression would sensitise tumours to cell death.
