Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Question: In rats, oral oleoyl-estrone (OE) decreases food intake and body lipid content. The aim of this study was to determine whether OE treatment affects the energy metabolism of pregnant rats and eventually, of their pups; i.e. changes in normal growth patterns and the onset of obesity after weaning.', 'Pregnant Wistar rats were treated with daily intragastric gavages of OE in 0.2 ml sunflower oil from days 11 to 21 of pregnancy (i.e. 10 nmol oleoyl-estrone/g/day). Control animals received only the vehicle. Plasma and hormone metabolites were determined together with variations in cellularity of adipose tissue.', "Treatment decreased food intake and lowered weight gain during late pregnancy, mainly because of reduced adipose tissue accumulation in different sites. OE-treated pregnant rats' metabolic pattern after delivery was similar to that of controls. Neonates from OE-treated rats weighed the same as those from controls. They also maintained the same growth rate up to weaning, but pups from OE-treated rats slowed their growth rate afterwards, despite only limited differences in metabolite concentrations.

Answer: Does treatment of pregnant rats with oleoyl-estrone slow down pup fat deposition after weaning?


Question: The brain-derived neurotrophic factor (BDNF) gene is a candidate gene in therapeutic responses to antidepressants. The aim of the study was to determine the effects of BDNF allelic variability on responses to escitalopram treatment at 3\xa0weeks after treatment initiation and at a 6-week endpoint.', 'We included 187 Caucasian subjects with depression; 153 completed the 6-week study. Clinical evaluation was performed using the Montgomery and Asberg Depression Rating Scale (MADRS) before and after 3-6 weeks of treatment.', 'After 3\xa0weeks of treatment, we saw significantly better treatment responses in the Met carriers and greater antidepressant resistance among the Val/Val homozygotes. Relative to Val/Val homozygous (59.78\xa0%), a significantly greater proportion of subjects Met-carriers (77.94\xa0%) responded to escitalopram treatment (χ (2)\u2009=\u20095.88, p\u2009=\u20090.015). After 6\xa0weeks, we found the same pattern of results but this effect did not reach statistical significance (χ (2)\u2009=\u20092.07, p\u2009=\u20090.15).

Answer: Is the BDNF Val ( 66 ) Met polymorphism associated with escitalopram response in depressed patients?


Question: Notch signaling is indicated as novel therapeutic targets to prevent recurrence of breast cancer. LncRNAs were identified as downstream target of Notch pathway. However, the exact mechanisms involved in Notch signaling, lncRNAs and breast cancer remain to be explained.', 'This original research aimed to determine the prognostic implications of Notch-1 for breast cancer, and explain mechanisms involved in regulation of lnRNA GAS5 by Notch-1, and identify the function of this mechanism on breast cancer.', 'Thirty breast cancer patients were included from The First Affiliated Hospital of Anhui Medical University (China) since January 2006 in this study. The mRNA level by RT-PCR and protein level of Notch-1 by western blot in tumor tissues and adjacent normal tissues were evaluated and 5-year survival analysis was applied to examine the significance of Notch-1. The levels of ten reported lncRNAs were determined by RT-PCR, and subsequently linear analysis was applied to analyze the relationship between these four unique lncRNAs and protein level of Notch-1, which identified the most relevant lncRNA GAS5 with Notch-1 in breast cancer. Subsequently, Notch1-siRNA was applied to influence the expression of Notch-1 in T47D, then the level of RSA5 was measured by RT-PCR, and CCK-8 assay was applied to measure the proliferation of T47D cells.', 'High level of Notch-1 provided a poor prognosis in breast cancer. Interference of Notch-1 significantly suppressed proliferation of T47D cell (P < 0.05), and significantly increased the level of GAS5.

Answer:
Does notch-1 promote breast cancer cells proliferation by regulating LncRNA GAS5?
