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: Hepatic expression of growth hormone (GH)-inducible genes serine protease inhibitor (Spi 2.1) and insulin-like growth factor (IGF)-I are inhibited by interleukin (IL)-1. The current study examines the role of the nuclear factor kappaB (NFkappaB) pathway and suppressor of cytokine signaling (SOCS)-3 expression as potential mechanisms for IL-1-mediated GH resistance.', 'CWSV-1 hepatocytes were cotransfected with Spi 2.1 or IGF-1 promoter luciferase constructs and empty pCMV4 vector or dominant negative inhibitor-kappaBalpha (IkappaBalpha)S/A construct. Cells were treated with or without IL-1 and then stimulated with or without recombinant human GH. Cell extracts were assayed for luciferase activity and protein, normalized and expressed as fold-induction. CWSV-1 cells transfected with pCMV4 or IkappaBalphaS/A were treated with or without IL-1 then SOCS-3 mRNA was measured. Finally, CWSV-1 cells were cotransfected with a SOCS-3 promoter construct with or without pCMV4 or IkappaBalphaS/A and then stimulated with or without IL-1 to investigate SOCS-3 promoter activity.', 'CWSV-1 cells cotransfected with pCMV4 demonstrated a three- to fivefold induction of Spi 2.1 or IGF-1 promoter activity after GH stimulation that was almost completely inhibited by IL-1. Cotransfection with IkappaBalphaS/A increased GH-inducible Spi 2.1 and IGF-1 promoter activity, but the inhibitory effects of IL-1 on both promoters were attenuated by cotransfection with IkappaBalphaS/A. IL-1 stimulated SOCS-3 mRNA expression and promoter activity. Cotransfection with IkappaBalphaS/A increased IL-1-inducible SOCS-3 promoter activity, but not SOCS-3 mRNA or protein.\Question: Does nuclear factor kappaB mediate the inhibitory effects of interleukin-1 on growth hormone-inducible gene expression?

A: Signaling via the NFkappaB pathway is responsible for the inhibitory effects of IL-1 on GH-inducible gene expression by a mechanism that does not seem to involve increased SOCS-3 expression.

Q: Context: The objective of the present study was to investigate the relationship between colorectal and prostate cancer.', 'All Victorian men who developed metachronous colorectal and prostate cancer with the first primary diagnosed between 1982 and 1993 were identified retrospectively from the Victorian Cancer Registry and were followed up to the end of 1995. Analyses were stratified by age group and years of follow up. The cause of death in those men who had prostate cancer following colorectal cancer was determined. The stage of colorectal cancer was compared between men with and without second primary prostate cancer and the grade of prostate cancer was compared with men who did not have a prior colorectal cancer.', 'Men who develop colorectal cancer are at increased risk of prostate cancer, with the greatest risk in men under the age of 65 (Relative risk approximately 2). Men with first primary colorectal cancer are more likely to develop prostate cancer than colorectal second primaries, and men who develop second primary prostate cancer are more likely to die of prostate cancer than colorectal cancer.\Question: Are men with colorectal cancer predisposed to prostate cancer?

A: Younger men diagnosed with colorectal cancer are at increased risk of prostate cancer. However, there is no direct evidence that screening for prostate cancer leads to a reduction in mortality. This should be considered when discussing long-term follow up.

Q: Context: The protein tyrosine kinase focal adhesion kinase (FAK) and Src in association with phosphorylation of the adapter protein paxillin are essential in tumor metastasis formation. Elevated levels of FAK, Src and paxillin may increase the metastatic potential of colorectal tumor cells. The aim of the current study was to examine the expression of FAK, Src, and paxillin using immunohistochemistry in the context of disease progression and to evaluate its clinical significance as a prognostic factor.', 'The relationship between FAK, Src and paxillin levels and colorectal cancer progression was evaluated by immunohistochemistry in 104 colorectal cancer specimens with clinical follow up. In addition, FAK, Src and paxillin expression levels were quantified in 68 colorectal tumors and corresponding liver metastases.', 'FAK and paxillin expression individually did not significantly impact time to recurrence (p=0.09, and p=0.89 respectively). Src expression was associated with tumor recurrence p=0.03. However, tumors that expressed both high FAK and Src levels had a significant shorter time to recurrence (p=0.004, hazard ratio: 2.98, 95% CI 1.14-6.31). FAK, Src and paxillin showed equivalent levels in corresponding liver metastases compared to the primary tumors (p=0.67, p=0.28 and p=0.34 respectively).\Question: Is combined expression of the non-receptor protein tyrosine kinases FAK and Src in primary colorectal cancer associated with tumor recurrence and metastasis formation?

A:
These findings show that high levels of FAK and Src combined were predictive for recurrence of colorectal cancer. In addition, expression of FAK, Src and paxillin in colorectal cancer were maintained in corresponding distant metastases.
