Gene expression of inflammatory markers and growth factors in placenta in relation to maternal obesity and foetal and postnatal growth
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Maternal obesity is a growing health problem, that contributes to obstetrical complications in pregnancy, as well as neonatal morbidity and mortality. The placenta serves for gas and nutrient exchange between the mother and the foetus, and obesity may influence and modify placental growth and function. The aims of this thesis were to investigate associations between maternal obesity without associated morbidity and gene expression of inflammatory markers and growth factors in the placenta, as well as offspring birth weight and postnatal growth. Study I and III were designed as matched case-control studies including 32 obese women with an early pregnancy body mass index (BMI) ≥ 35.0 kg/m2, study II was an experimental study examining twelve placentas of normal weight women, and study IV was a cohort study including 109 obese women with a BMI ≥ 34.5 kg/m2. In studies I-IV analyses of gene expression were performed and in study III additionally cord blood concentrations were determined. No difference was found in the occurrence of placental gene expression of inflammatory markers or growth factors between obese and normal weight women, nor did the sampling site in placentas of normal weight women influence gene expression of these markers, except for leptin gene (LEP) and insulin receptor gene (INSR) expression. Ghrelin gene (GHRL) and LEP expression, as well as cord blood ghrelin and adiponectin levels, was not altered in maternal obesity, and a negatively U-shaped relationship between LEP expression and infant birth weight (BW) z-scores was observed in the placentas of obese women.In conclusion, no statistically significant difference in gene expressions of inflammatory markers and growth factors in the placenta between severely obese and normal weight women was found. These results are in contrast with earlier studies and could be due to the fact that we examined mainly healthy obese women. The correlations we found between gene expression of leptin in the placenta and the birth weight of the infants warrants further studies.

- Double-blind placebo-controlled intervention using glutamic acid decarboxylase (GAD)-alum, vitamin D and Ibuprofen in recent onset Type I diabetes (T1D).64 patients (T1D since <4months, age 10-17.99, fasting sC-peptide ≥0.12nmol/l, GADA-positive) were randomized intoDay(D) 1-90 400mg/day Ibuprofen, D1-450 vitamin D 2000IU/day, D15, 45 sc. 20μg GAD-alum; as A but placebo instead of Ibuprofen; as B but 40μg GAD-alum D15, 45; placebo.Treatment was safe and tolerable. No C-peptide preservation was observed. We observed a linear correlation of baseline C-peptide, HbA1c and insulin/per kilogram/24h with change in C-peptide AUC at 15months (r=-0.776, p<0.0001).Ibuprofen, vitamin D + GAD-alum did not preserve C-peptide. Treatment efficacy was influenced by baseline clinical and immunological factors and vitamin D concentration. Clinical Trial Registration: NCT01785108 (ClinicalTrials.gov).

- Prostate cancer (PC) is a common cancer among men, and preventive strategies are warranted. Benzoxazinoids (BXs) in rye have shown potential against PC in vitro but human studies are lacking. The aim was to establish a quantitative method for analysis of BXs and investigate their plasma levels after a whole grain/bran rye vs refined wheat intervention, as well as exploring their association with PSA, in men with PC. A quantitative method for analysis of 22 BXs, including novel metabolites identified by mass spectrometry and NMR, was established, and applied to plasma samples from a randomized crossover study where patients with indolent PC (n = 17) consumed 485 g whole grain rye/rye bran or fiber supplemented refined wheat daily for 6 wk. Most BXs were significantly higher in plasma after rye (0.3–19.4 nmol/L in plasma) vs. refined wheat (0.05–2.9 nmol/L) intake. HBOA-glc, 2-HHPAA, HBOA-glcA, 2-HPAA-glcA were inversely correlated to PSA in plasma (p < 0.04). To conclude, BXs in plasma, including metabolites not previously analyzed, were quantified. BX metabolites were significantly higher after rye vs refined wheat consumption. Four BX-related metabolites were inversely associated with PSA, which merits further investigation.

- Background & aims: Rye consumption has shown beneficial effects on prostate cancer tumors, as indicated by slower initial tumor growth in animal models and lowering of prostate-specific antigen (PSA) in humans. This study evaluated the effects of whole grain/bran rye consumption on low-grade inflammation and endothelial function biomarkers in men with prostate cancer. Methods: Seventeen men with untreated, low-grade prostate cancer consumed 485 g rye whole grain and bran products (RP) per day or refined wheat products with added cellulose (WP) in a randomized crossover design. Fasting blood samples were taken before and after 2, 4, and 6 weeks of treatment. Results: Concentrations of tumor nuclear factor-receptor 2 (TNF-R2), e-selectin, and endostatin were significantly lower after consumption of the RP diet compared with WP (p < 0.05). Cathepsin S concentration was positively correlated to TNF-R2 and endostatin concentrations across all occasions. Strong correlations were consistently found between intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) and between interleukin-6 (IL-6) and interleukin-1 receptor antagonist (IL-1RA). No effect of intervention was found in 92 inflammation-related protein biomarkers measured in a proximity extension assay. Conclusions: RP diet lowered TNF-R2, e-selectin, and endostatin, compared with WP in men with prostate cancer. These effects were accompanied by a reduction in PSA.

- Norrlandsmodellen gör Umeå till modell för framtidens samhällsbyggnad. I Umeå. I Norrland.I ett Sverige som ska visa vägen mot tillgänglighet och demokrati i vår tid. I en värld som behöver läka ihop centrum och periferi, stad och landsbygd, konsumtion och återbruk.Medborgarna har redan engagerats. Och med dem i centrum öppnar sig en unik möjlighet att utveckla ett framtidens Umeå.De gamla europavägarna ger plats för framtiden att gradvis växa fram. Staden kan sys ihop och stadsdelarna får bättre kontakt med varandra.En hållbar livsmiljö, kunskapsstaden och kulturstaden Umeå får en jordmån att växa in de krav som ställs idag: smarta klimatlösningar, zero waste och ökad lokal demokrati samt självförsörjning.Allt börjar i medborgarna. Och fortsätter i samverkan. Välkommen till NORRLANDSMODELLEN.
