- To investigate the expression levels of CXCL10 and CXCR3 in tumors from breast cancer patients randomized to adjuvant tamoxifen treatment or no endocrine treatment, in order to further study the connection to prognosis and prediction of tamoxifen treatment outcome. Immunohistochemistry on tissue microarrays from 912 breast cancer patients randomized to tamoxifen or no endocrine treatment. CXCR3 status was found to be a prognostic tool in predicting distant recurrence, as well as reduced breast cancer-specific survival. In patients with estrogen receptor (ER)-positive tumors, tumors with strong CXCL10 levels had improved effect of tamoxifen treatment in terms of local recurrence-free survival [risk ratio (RR) 0.46 (95 % CI 0.25-0.85, P = 0.01)] compared with patients with tumors expressing weak CXCL10 expression. Further, patients with ER-positive tumors with strong CXCR3 expression had an improved effect of tamoxifen in terms of breast cancer-specific survival [RR 0.34 (95 % CI 0.19-0.62, P less than 0.001)] compared with the group with weak CXCR3 levels [RR 1.33 (95 % CI 0.38-4.79, P = 0.65)]. We show here for the first time that CXCL10 and CXCR3 expression are both predictors of favorable outcome in patients treated with tamoxifen.

- A survey was conducted to investigate investment style and drivers of socially responsible investment (SRI) among institutional investors. Respondents were 60 professionals working as SRI or non-SRI investors in 19 different Swedish banks, pension funds, or mutual fund companies. The results showed that non-SRI investors perceived market regulations to be a strong driver of SRI, while SRI investors perceived others’ behavior to be a strong driver. No differences were found between SRI and non-SRI investors with respect to short-term versus long-term or active versus passive investment styles.

Should pension funds´ fiduciary duty be extended to include social, ethical and environmental concerns? A study of beneficiaries´preferences

- Many fund managers, lawyers and academics assume that pension funds' legal responsibility to manage assets in the best interests of their beneficiaries (their fiduciary duty) rules out including social, ethical and environmental concerns in investments. A counter-argument is that beneficiaries' best interests can be interpreted more broadly to also encompass such concerns. We seek to contribute to resolving this controversy by measuring preferences for social responsible investment (SRI) among beneficiaries of pension funds. The data from a survey questionnaire answered by 1119 future beneficiaries of the Swedish pension system show that beneficiaries on average prefer their pension funds to go beyond financial concerns and engage in SRI. Analysing the determinants of the preferences, we find support for a model including both financial motives (beliefs about financial risk and returns) and values-based motives (self-transcendent value priorities). Our results give unique insights into the psychological drivers of beneficiaries' preferences that are highly pertinent to present attempts at rethinking the aims of pension investments.

Predictive relevance of HOXB13 protein expression for tamoxifen benefit in breast cancer
- 2010
-
Ingår i: Breast Cancer Research. - : Springer Science and Business Media LLC. - 1465-5411 .- 1465-542X. ; 12:4

Tidskriftsartikel (refereegranskat)abstract
- ABSTRACT: INTRODUCTION: The HOXB13:IL17BR index has been identified to predict clinical outcome in the setting of adjuvant tamoxifen monotherapy of breast cancer. Further studies have shown that HOXB13 in particular can indicate benefit of prolonged tamoxifen treatment. Patients with high-expressing tumors did not benefit from prolonged treatment, suggesting that HOXB13 might be involved in tamoxifen resistance. No studies have been made regarding the HOXB13 protein levels in breast cancer. The aim of our study was to investigate whether tamoxifen benefit can be correlated to different levels of HOXB13 protein expression. METHODS: We used immunohistochemistry to analyze protein levels of HOXB13 in tumor samples from 912 postmenopausal node-negative breast cancer patients randomized to adjuvant tamoxifen therapy or no endocrine treatment. RESULTS: Tamoxifen-treated patients with estrogen receptor-positive tumors expressing none or low levels of HOXB13 had a clear benefit from tamoxifen in terms of longer distant recurrence-free survival (DRFS) (hazard ratio = 0.38, 95% confidence interval = 0.23 to 0.60, P = 0.000048). However, for patients with a high or intermediate HOXB13 tumor expression, tamoxifen did not prolong the DRFS compared with the untreated patients (hazard ratio = 0.88, 95% confidence interval = 0.47 to 1.65, P = 0.69). Interaction between HOXB13 expression and benefit from tamoxifen was statistically significant for DRFS (P = 0.035). No prognostic value could be ascribed to HOXB13 among systemically untreated patients. CONCLUSIONS: A high HOXB13 expression was associated with decreased benefit from tamoxifen, which indicates that HOXB13 protein level may be used as a predictive marker for tamoxifen treatment.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: 17β-hydroxysteroid dehydrogenases (17βHSDs) are important enzymes regulating the pool of bioactive steroids in the breast. The current study was undertaken in order to evaluate implications of 17βHSD14 in breast cancer, measuring 17βHSD14 protein expression in breast tumours.Methods: An antibody targeting the 17βHSD14 antigen was generated and validated using HSD17B14-transfected cells and a peptide-neutralising assay. Tissue microarrays with tumours from 912 post-menopausal women diagnosed with lymph node-negative breast cancer, and randomised to adjuvant tamoxifen or no endocrine treatment, were analysed for 17βHSD14 protein expression with immunohistochemistry.Results: Results were obtained from 847 tumours. Patients with oestrogen positive tumours with high 17βHSD14 expression had fewer local recurrences when treated with tamoxifen (HR 0.38; 95% C.I. 0.19–0.77, p = 0.007) compared to patients with lower tumoural 17βHSD14 expression, for whom tamoxifen did not reduce the number of local recurrences (HR 1.19; 95% C.I. 0.54–2.59; p = 0.66). No prognostic importance of 17βHSD14 was seen for systemically untreated patients.Conclusions: Using a highly specific validated antibody for immunohistochemical analysis of a large number of breast tumours, we have shown that tumoural expression levels of 17βHSD14 can predict the outcome of adjuvant tamoxifen treatment in terms of local recurrence-free survival in patients with lymph node-negative ER+ breast cancer. The results need be verified to confirm any clinical relevance.

Leptin predicts independently a first-ever STEMI in men, data from a large prospective nested case-referent study
- 2013

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Purpose: The adipocyte derived hormone leptin could be a mediator between obesity and increased risk for cardiovascular disease (CVD), asleptin has been linked to the atherosclerotic process. We hypothesised that leptin predicted independently a myocardial infarction (MI).Methods: A prospective nested case-referent study was set up within the framework of the Northern Sweden MONitoring of Trends and Determinants in CArdiovascular Diseases (MONICA) project, the Västerbotten Intervention Program (VIP), and the Mammary Screening Program (MSP). Subjects (n=564, 40% women) with a first-ever acute MI that had participated in one of these surveys prior to the MI were selected. Age, sex, survey and location matched referents (n=1082, 40% women) were selected within the surveys. Leptin was measured instored plasma. Conditional logistic regression was used to determine the risk for MI. Type of MI (STEMI and NSTEMI) was classified according to Minnesota codes.Results: The time period between survey and event was 3.9 years (interquartile range 3.6), and 51% of the cases had STEMI, 29% had NSTEMI, and 21% were unclassified. Male and female cases had higher levels of leptin (5.0 vs. 4.1 ng/mL, p<0.001 and 15.4 vs. 14.0 ng/mL, p=0.03), compared to referents. High leptin levels predicted MIindependently in men (OR 2.17 [1.32-3.54], ptrend<0.001), but not inwomen (OR 1.10 [0.55-2.18], ptrend=0.05). The risk related to leptin inmen was seen for STEMI in particular.Conclusions: High leptin predicts first–ever fatal and non–fatal MI, notably with a gender and MI-type difference. Leptin may affect theatherosclerotic process differentially in men and women and may promote plaque rupture and thrombus formation in larger coronary vessels.

- Background: High intakes of saturated fat have been associated with cardiovascular disease, and milk fat is rich in saturated fat. Objective: The objective of this study was to investigate the association between the serum milk fat biomarkers pentadecanoic acid (15:0), heptadecanoic acid (17:0), and their sum (15:0+17:0) and a first myocardial infarction (MI). Design: The study design was a prospective case-control study nested within a large population- based cohort in Sweden. Included in the study were 444 cases (307 men) and 556 controls (308 men) matched on sex, age, date of examination, and geographic region. Clinical, anthropometric, biomarker fatty acid, physical activity, and dietary data were collected. The odds of a first MI were investigated by using conditional logistic regression. Results: In women, proportions of milk fat biomarkers in plasma phospholipids were significantly higher (P < 0.05) in controls than in cases and were, in general, negatively, albeit weakly, correlated with risk factors for metabolic syndrome. The crude standardized odds ratios of becoming an MI case were 0.74 (95% CI: 0.58, 0.94) in women and 0.91 (95% CI: 0.77, 1.1) in men. After multivariable adjustment for confounders, the inverse association remained in both sexes and was significant in women. In agreement with biomarker data, quartiles of reported intake of cheese (men and women) and fermented milk products (men) were inversely related to a first MI (P for trend < 0.05 for all). Conclusions: Milk fat biomarkers were associated with a lower risk of developing a first MI, especially in women. This was partly confirmed in analysis of fermented milk and cheese intake. Components of metabolic syndrome were observed as potential intermediates for the risk relations. Am J Clin Nutr 2010; 92:194-202.
