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 the methionine-choline deficient dietary model of steatohepatitis exhibit insulin resistance?
Answer: GTT, ITT and QUICKI confirmed the absence of insulin resistance in the MCD fed mice. This model causes fibrosing steatohepatitis and may help delineate the non-insulin resistant mechanisms involved in human steatohepatitis.
answer:
no
