PROBLEM: To assess the relationship between congenital uterine malformations and blood pressure in pregnancy.', 'Twenty-four-hour automated ambulatory blood pressure monitoring (readings every 30 min) was performed in 16 normotensive, nonproteinuric, primigravidae with congenital uterine malformations (5 uterus septus, 9 uterus bicornis, 2 uterine didelphys) between 20 and 30 weeks. From the 24-hr blood pressure report, we calculated 24-hr mean, daytime and nighttime means. The results were compared with 16 primigravidae, matched for age and gestation, who were and remained normotensive throughout pregnancy, and tested for statistics with t-test; significance assessed at p < 0.001.', 'Although they were within the normotensive range, all blood pressure measurements considered were significantly higher in pregnant women with congenital uterine malformations, compared to normal pregnant women. Namely, 24-hr, daytime, and nighttime systolic (mean +/- SD) were 121.1 +/- 8.4, 124.4 +/- 8.8, 114.0 +/- 7.7 mmHg, respectively, in women with uterine malformations and 108.0 +/- 7.4, 109.2 +/- 7.3, 102.1 +/- 8.5 mmHg, respectively, in normal pregnant women. Twenty-four-hour diastolic, daytime, and nighttime diastolic (mean +/- SD) 74.1 +/- 10.2, 77.1 +/- 10.6, 68.1 +/- 9.2 mmHg, in women with uterine malformations and 64.1 +/- 5.7, 66.0 +/- 5.7, 58.2 +/- 6.3 mmHg, in normal pregnant women (all differences p < 0.001). Fifteen of the fetuses from women with congenital uterine malformations showed intrauterine growth retardation. No differences were found 6 months after delivery.

SOLUTION: Are congenital uterine malformations associated to increased blood pressure in pregnancy?

PROBLEM: To examine the expression of Twist1 in cervical cancer and to explore its biological function in the progression of cervical cancer.\u2029', 'The expressions of Twist1 in 32 cervical cancers and matched normal tissues were examined by immunohistochemistry (IHC). Cell invasive ability and the expression of invasion-related genes were determined in RNAi-based Twist1-silencing HeLa cells. The relationship between Twist1 and microRNA-33a (miR-33a) in cervical cancer was studied by Pearson correlation analysis, and the roles of miR-33a in regulation of Twist1 and cell invasiveness were studied.\u2029', 'The positive expression rate of Twist1 was 75.0% (24/32) and 21.9% (7/32) in the cervical cancer and the matched normal tissues, respectively, with significant difference between them (P<0.05). Twist1 shRNA significantly decreased the invasiveness of HeLa cells (P<0.05). Compared with the matched normal tissues, the expression of miR-33a was increased in the cervical cancer tissues, which was negatively correlated with Twist1 (r=-0.661, P<0.05). Overexpression of miR-33a could significantly suppress Twist1 expression as well as cell invasiveness (P<0.05).\u2029

SOLUTION: Does [ MicroRNA-33a regulate the invasion of cervical cancer cells via targeting Twist1 ]?

PROBLEM: We investigated parent-of-origin and allele-specific expression effects on obesity and hepatic gene expression in reciprocal crosses between the Berlin Fat Mouse Inbred line (BFMI) and C57Bl/6NCrl (B6N).', 'We found that F1-males with a BFMI mother developed 1.8 times more fat mass on a high fat diet at 10 weeks than F1-males of a BFMI father. The phenotype was detectable from six weeks on and was preserved after cross-fostering. RNA-seq data of liver provided evidence for higher biosynthesis and elongation of fatty acids (p\u2009=\u20090.00635) in obese male offspring of a BFMI mother versus lean offspring of a BFMI father. Furthermore, fatty acid degradation (p\u2009=\u20090.00198) and the peroxisome pathway were impaired (p\u2009=\u20090.00094). The circadian rhythm was affected as well (p\u2009=\u20090.00087). Among the highest up-regulated protein coding genes in obese males were Acot4 (1.82 fold, p\u2009=\u20090.022), Cyp4a10 (1.35 fold, p\u2009=\u20090.026) and Cyp4a14 (1.32 fold, p\u2009=\u20090.012), which hydroxylize fatty acids and which are known to be increased in liver steatosis. Obese males showed lower expression of the genetically imprinted and paternally expressed 3 (Peg3) gene (0.31 fold, p\u2009=\u20090.046) and higher expression of the androgen receptor (Ar) gene (2.38 fold, p\u2009=\u20090.068). Allelic imbalance was found for expression of ATP-binding cassette transporter gene Abca8b. Several of the differentially expressed genes contain estrogen response elements.

SOLUTION:
Does the direction of cross affect [ corrected ] obesity after puberty in male but not female offspring?
