Question: Question: Does increased expression of prostasin contribute to early-onset severe preeclampsia through inhibiting trophoblast invasion?
Answer: These findings suggest that prostasin may suppress the invasion process in preeclampsia by attenuating MMP2 and MMP9 secretion.

Answer: yes


Question: Question: Is lubricin a product of megakaryocyte stimulating factor gene expression by human synovial fibroblasts?
Answer: Lubricin is secreted by synovial fibroblasts via expression of the MSF gene. Lubricin is constructed of MSF exons 6 through 9 but the presence of other exons cannot be excluded. Lubricin/MSF is the only lubricating component in the final lubricating fraction of human synovial fluid.

Answer: yes


Question: Question: Does whole-genome bisulfite sequencing of multiple individuals reveal complementary roles of promoter and gene body methylation in transcriptional regulation?
Answer: Our results suggest that DNA methylation outside promoters also plays critical roles in gene regulation. Future studies on gene regulatory mechanisms and disease-associated differential methylation should pay more attention to DNA methylation at gene bodies and other non-promoter regions.

Answer:
yes
