In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[Q]: Context: Stat6 signaling is active in cancer cells and IL-4-induced Stat6 activities or Stat6 activational phenotypes vary among cancer cells. This study aimed at investigating possible mechanism(s) involved in the formation of varying Stat6 activities/phenotypes.', "Stat6 regulatory genes, SOCS-1 and SHP-1, were examined for mRNA expression using RT-PCR, and their promoter DNA methylation was assayed by methylation-specific PCR in Stat6-phenotyped colon cancer cell lines. DNA methylation was then verified by sequencing. RT-PCR assay and Western blotting were used to detect the expression of SOCS-1 and SHP-1 after demethylation using 5-aza-2'-deoxycytidine.", "Compared with Stat6(null) Caco-2 cells, Stat6(high) HT-29 cells showed decreased constitutive expression of SOCS-1 and SHP-1, which correlated with DNA hypermethylation in these genes' promoters. Interestingly, demethylation in HT-29 cells recovered the constitutive expression of SOCS-1 and SHP-1.\Question: Does dNA methylation regulate constitutive expression of Stat6 regulatory genes SOCS-1 and SHP-1 in colon cancer cells?
[A]: These findings suggest that DNA methylation controls the constitutive expression of negative Stat6 regulatory genes, which may affect Stat6 activities.

[Q]: Context: Recent studies have implicated central nicotinic cholinergic receptor systems in the reinforcing properties of alcohol. In laboratory animals, mecamylamine, a central nicotinic receptor antagonist, reduces the consumption of and preference for alcohol. This study investigated the effect of mecamylamine on the subjective responses to alcohol in humans. It was hypothesized that mecamylamine (7.5 and 15 mg) would attenuate the stimulant-like subjective effects of alcohol (0.8 g/kg) and decrease the self-reported desire to consume additional alcohol beverages.', 'Fourteen male and 13 female nonsmokers participated in 6 laboratory sessions. During each session, subjects received, in randomized order under double-blinded conditions, a capsule containing mecamylamine (7.5 or 15 mg) or placebo followed by a beverage containing alcohol (0.8 g/kg) or placebo. Physiologic and subjective-effect measures were taken at 30-min intervals for 2 hr after beverage consumption.', 'Mecamylamine attenuated the stimulant and euphoric effects of alcohol and reduced the self-reported desire to consume additional alcohol beverages. This effect was most pronounced in men, even though women exhibited greater physiologic reactions to mecamylamine.\Question: Does mecamylamine attenuate the subjective stimulant-like effects of alcohol in social drinkers?
[A]: These findings suggest that nicotinic cholinergic receptors are involved in mediating some of the stimulant-like effects of alcohol.

[Q]: Context: Although highly controversial, directto-consumer (DTC) television advertising for prescription drugs is an established practice in the US health care industry. While the US Food and Drug Administration is currently reexamining its regulatory stance, little evidence exists regarding the impact of DTC advertising on patient health outcomes.', 'The objective of this research was to study the relationship between heavy television promotion of 3 major hydroxymethylglutaryl coenzyme A reductase inhibitors ("statins") and the frequency with which patients are able to attain low-density lipoprotein cholesterol (LDL-C) blood-level goals after treatment with any statin.', 'We used logistic regression to determine achievement of LDL-C goals at 6 months after statin treatment, using electronic medical record extract data from patients from geographically dispersed primary care practices in the United States. We identified LDL-C blood levels as being at or less than goal, as defined by risk-adjusted guidelines published by the National Heart, Lung, and Blood Institute from the Adult Treatment Panel III (ATP III) data. A total of 50,741 patients, identified from 88 practices, were diagnosed with hyperlipidemia and had begun therapy with any statin medication during the 1998-2004 time period. In addition, total dollars spent each month on television advertising at the national and local levels for atorvastatin, pravastatin, and simvastatin were obtained. DTC advertising data were merged by local media market where the physician practice was located and by the month in which the patient was first prescribed a statin. The models were run for all patients who initiated therapy, and also on a subsample of patients who continued to receive prescriptions for the drugs for at least 6 months. Logistic regressions were used to predict the likelihood that each patient attained the ATP III LDL-C blood-level goals as a function of DTC advertising and other factors.', 'High levels of national DTC advertising when therapy was initiated were found to increase the likelihood that patients attained LDL-C goals at 6 months by 6% (P < 0.001)-although the effect was concentrated among patients with the least-restrictive ATP III LDL-C goals (<or=160 mg/dL). This result was found in both the entire set of patients as well as the restricted sample of patients who maintained therapy for at least 6 months.\Question: Do effects of direct-to-consumer advertising of hydroxymethylglutaryl coenzyme a reductase inhibitors on attainment of LDL-C goals?
[A]:
The results of this study suggest that higher levels of DTC television advertising of statin treatment were significantly associated with improvements in the likelihood of attaining cholesterol-management goals for at least some patients. While this paper does not address the impact of DTC advertising on the costs of care or on unnecessary switching between statin treatments, the results do suggest that DTC advertising can have beneficial effects, which should be a factor when additional restrictions on DTC advertising are considered. This result-that DTC ad vertising might have beneficial effects-should be weighed against existing studies that have found that patients' suggestions (conceptually which could be induced by DTC advertising) may be associated with overprescribing (eg, in the case of the use of antidepressants for adjustment disorder).
