Given a passage with a context and an answer, 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.

Q: Context: The authors previously described the complete regression of established neuroblastoma (NB) by the adoptive transfer of syngeneic interleukin-12 transduced dendritic cells (DC) from naive mice. However, some malignancies, like NB, abrogate DC immunostimulation. The authors hypothesize that IL-12 transduction of DC from NB-bearing mice will have the same antitumor properties.', 'A/J mice (n = 32) with established NB received peritumoral injection of 1 x 10(6) DC (DC, IL-12 DC, day 7 IL-12 DC or day 14 IL-12 DC) on day 7. Tumor growth, phenotype, and ability to induce NK and T cell activity were measured.', 'Vaccination with naive admIL-12 DC resulted in 100% tumor regression and prolonged survival. Transduced DC induced only partial responses in 75% (day 7) and 25% (day 14) of animals. No differences in phenotype or effector cell activation were noted between admIL-12DC in tumor-bearing or naive mice.
Answer: IL-12 DC from tumor-bearing animals have a decreased ability to induce antitumor activity against established murine NB. This decreased capacity appears to be related to the duration of exposure to tumor because day 14 transduced DC had less of an effect than day 7 DC, despite similar phenotypes and ability to activate immune effector cells.

Q: Context: We utilized whole-genome mapping of promoters that are activated by DNA hypomethylation in hepatocellular carcinoma (HCC) clinical samples to shortlist novel targets for anticancer therapeutics. We provide a proof of principle of this approach by testing six genes short-listed in our screen for their essential role in cancer growth and invasiveness.', 'We used siRNA- or shRNA-mediated depletion to determine whether inhibition of these genes would reduce human tumor xenograft growth in mice as well as cell viability, anchorage-independent growth, invasive capacities, and state of activity of nodal signaling pathways in liver, breast, and bladder cancer cell lines.', 'Depletion of EXOSC4, RNMT, SENP6, WBSCR22, RASAL2, and NENF effectively and specifically inhibits cancer cell growth and cell invasive capacities in different types of cancer, but, remarkably, there is no effect on normal cell growth, suggesting a ubiquitous causal role for these genes in driving cancer growth and metastasis. Depletion of RASAL2 and NENF in vitro reduces their growth as explants in vivo in mice. RASAL2 and NENF depletion interferes with AKT, WNT, and MAPK signaling pathways as well as regulation of epigenetic proteins that were previously demonstrated to drive cancer growth and metastasis.
Answer: Our results prove that genes that are hypomethylated and induced in tumors are candidate targets for anticancer therapeutics in multiple cancer cell types. Because these genes are particularly activated in cancer, they constitute a group of targets for specific pharmacologic inhibitors of cancer and cancer metastasis.

Q: Context: Fatigue is likely to be an important limiting factor in adolescents with spastic cerebral palsy (CP).', 'To determine the effects of walking-induced fatigue on postural control adjustments in adolescents with unilateral CP and their typically developing (TD) peers.', 'Ten adolescents with CP (14.2 ± 1.7 yr) and 10 age-, weight- and height-matched TD adolescents (14.1 ± 1.9 yr) walked for 15 min on a treadmill at their preferred walking speed. Before and after this task, voluntary strength capacity of knee extensors (MVC) and postural control were evaluated in 3 conditions: eyes open (EO), eyes closed (EC) and with dual cognitive task (EODT).', 'After walking, MVC decreased significantly in CP (-11%, P<0.05) but not in TD. The CoP area was only significantly increased in CP (90%, 34% and 60% for EO, EC and EODT conditions, respectively). The CoP length was significantly increased in the EO condition in CP and TD (20% and 21%) and was significantly increased in the EODT condition by 18% in CP only.
Answer: Unlike TD adolescents, treadmill walking for 15 min at their preferred speed lead to significant knee extensor strength losses and impairments in postural control in adolescents with unilateral spastic CP.
