Q: Context: Recent evidence has indicated that members of natural jasmonates, a family of plant stress hormones, exhibit anticancer activity. The current study was undertaken to investigate the effects of jasmonates on the in vitro growth of human neuroblastomas, one of the most common solid tumors in children.', 'Cellular proliferation was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide colorimetry and colony formation assay. Apoptosis was detected by Hoechst 33258 staining and flow cytometry. Western blotting was applied to assay gene expression.', 'The administration of natural jasmonates, methyl jasmonate, cis-jasmone, and jasmonic acid to cultured neuroblastoma cell line SH-SY5Y, resulted in a decrease of cell proliferation in a doseand time-dependent manner. However, the in vitro growth of cultured human embryonic kidney (HEK) cell line HEK 293 was not affected by jasmonates. The cell cycles of jasmonate-treated SH-SY5Y cells were arrested at the G2/M phase. The incubation of SH-SY5Y cells with jasmonates resulted in characteristic changes of apoptosis. The anticancer activities of natural jasmonates on SH-SY5Y cells are as follows: methyl jasmonate>cis-jasmone>jasmonic acid. In addition, the expressions of proliferating cell nuclear antigen and N-myc were downregulated by methyl jasmonate. Moreover, methyl jasmonate decreased the expression of the Xlinked inhibitor of apoptosis protein and survivin, critical members of inhibitors of the apoptosis protein family, in SH-SY5Y cells.
Answer: Jasmonates suppress the growth of human neuroblastoma cell line SH-SY5Y via inhibiting cell proliferation and inducing apoptosis, which lays the groundwork for further investigation into the anticancer activities and its mechanisms of natural jasmonates on human neuroblastomas.

Q: Context: DNA methylation is an important biological form of epigenetic modification, playing key roles in plant development and environmental responses.', 'In this study, we examined single-base resolution methylomes of Populus under control and drought stress conditions using high-throughput bisulfite sequencing for the first time. Our data showed methylation levels of methylated cytosines, upstream 2 kp, downstream 2kb, and repeatitive sequences significantly increased after drought treatment in Populus. Interestingly, methylation in 100 bp upstream of the transcriptional start site (TSS) repressed gene expression, while methylations in 100-2000 bp upstream of TSS and within the gene body were positively associated with gene expression. Integrated with the transcriptomic data, we found that all cis-splicing genes were non-methylated, suggesting that DNA methylation may not associate with cis-splicing. However, our results showed that 80% of trans-splicing genes were methylated. Moreover, we found 1156 transcription factors (TFs) with reduced methylation and expression levels and 690 TFs with increased methylation and expression levels after drought treatment. These TFs may play important roles in Populus drought stress responses through the changes of DNA methylation.
Answer: These findings may provide valuable new insight into our understanding of the interaction between gene expression and methylation of drought responses in Populus.

A: Do single-base-resolution methylomes of Populus trichocarpa reveal the association between DNA methylation and drought stress?

Q: Context: The interleukin (IL)-23/IL-17 axis plays an important role in various inflammatory conditions but its function in acute pancreatitis (AP) is not well understood. The present study investigated the relationship between serum levels of IL-23, IL-17, and C-reactive protein (CRP) in patients and the severity of AP.', 'Eighty-five patients with AP were categorized into mild group, moderately severe group, and severe group according to the revised Atlanta classification, 2012. Serum levels of IL-23 and IL-17 were measured by enzyme-linked immunosorbent assay in patients 48 hours after admission. The CRP levels of patients were also measured on admission and 48 hours after admission.', 'The serum levels of CRP of patients on admission and 48 hours after admission and levels of IL-23 and IL-17 of patients 48 hours after admission increased alone with the severity of AP, respectively (P < 0.01). The serum levels of IL-23 and IL-17 in the patients were correlated with CRP levels (r = 0.234, r = 0.552, P < 0.001, respectively).
Answer: The serum levels of IL-17, IL-23, and CRP are correlated with the severity of AP and represent valuable prognostic factors in the assessment of disease severity of patients with AP.

A:
Do increased interleukin-23/17 axis and C-reactive protein are associated with severity of acute pancreatitis in patients?
