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.

Context: Linitis plastica-type gastric carcinoma remains a disease with poor prognosis despite an aggressive surgical approach. Although a prominent pattern of disease failure is peritoneal carcinomatosis, some patients experience rapid disease progression without signs of the peritoneal disease.', 'Clinicopathologic data from 178 patients with linitis plastica-type gastric cancer operated on between 1991 and 2000 were analyzed. Survival stratified by curability of surgery, pN stage, and patterns of failure were evaluated by using the Kaplan-Meier method, and chi(2) test was used to evaluate correlation between the number of metastatic lymph nodes in terms of pN categories and the incidence of various patterns of metastasis and recurrence. Cox regression hazard model was used to identify independent prognostic factors.', 'R0 resection was performed only among 82 patients (46% of those who underwent laparotomy). Node metastasis was frequent with only 22 patients classified as pN0. Peritoneal carcinomatosis was observed in 131 patients and was the commonest pattern of recurrence. Bone metastasis, found in 13 patients, was associated with poor outcome, and its incidence was significantly correlated with the number of metastatic nodes. pT4 status and pN3 status were identified as significant independent prognostic determinants.\Question: Is the number of metastatic lymph nodes a significant risk factor for bone metastasis and poor outcome after surgery for linitis plastica-type gastric carcinoma?
Treatment strategy for the linitis plastica should in general combine surgery with aggressive treatment directed toward peritoneal disease. However, patients with >16 metastatic nodes more often are associated with bone metastasis than those with modest nodal involvement and suffer from poor prognosis.

Context: An intact and fully functional multiprotein DNA replication complex (DNA synthesome) from human as well as from murine mammary carcinoma cells was first isolated and characterized in our laboratory. The human cell synthesome supports the in vitro origin-specific simian virus 40 (SV40) DNA replication reaction in the presence of the viral large T-antigen using a semiconservative mechanism and has been shown to contain all the proteins and enzymes required to support DNA synthesis. We are currently using the DNA synthesome as a unique model for analyzing the mechanism of action of anticancer drugs affecting DNA replication. The purpose of this study was to further investigate the mechanism of action of ara-C using the DNA synthesome isolated from the human breast cancer cell line MDA MB-468.', 'Synthesome-mediated SV40 DNA replication was performed in the presence of various concentrations of ara-CTP (the active metabolite of ara-C) and the types of daughter DNA molecules produced were analyzed lusing neutral and alkaline gel electrophoresis. We also examined the effect of ara-C on intact MDA MB-468 cell DNA synthesis and on cell proliferation. In addition, we studied the effect of ara-CTP on the activity of some of the synthesome target proteins (the DNA polymerases alpha and delta).', 'Full-length daughter DNA molecules were obtained in the presence of low concentrations of ara-CTP while at higher concentrations, there was an inhibition of full-length daughter DNA synthesis. The findings suggest that specifically the initiation phase of DNA synthesis was inhibited by ara-CTP since the production of the short Okazaki fragments was suppressed at all concentrations of the drug above 10 microM. In addition, it was found that the IC50 of ara-CTP for inhibition of synthesome-mediated in vitro DNA replication was comparable to that required to inhibit intact cell DNA synthesis. Further experimentation has shown that ara-CTP preferentially inhibits the activity of the synthesome-associated DNA polymerase alpha enzyme while the DNA polymerase delta seems to be resistant to the inhibitory effect of that drug.\Question: Does ara-C affect formation of cancer cell DNA synthesome replication intermediates?
Our results indicate that ara-C's action on DNA replication is mediated primarily through DNA polymerase alpha and suggest that this enzyme plays a key role in DNA synthetic initiation events. The results also provide definitive support for the use of the DNA synthesome as a unique and powerful model for analyzing the mechanism of action of anticancer drugs which directly affect DNA replication.

Context: ANGPTL8 (betatrophin) has been recently identified as a regulator of lipid metabolism through its interaction with ANGPTL3. A sequence variant in ANGPTL8 has been shown to associate with lower level of Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL). The objective of this study is to identify sequence variants in ANGPTL8 gene in Arabs and investigate their association with ANGPTL8 plasma level and clinical parameters.', 'A cross sectional study was designed to examine the level of ANGPTL8 in 283 non-diabetic Arabs, and to identify its sequence variants using Sanger sequencing and their association with various clinical parameters.', 'Using Sanger sequencing, we sequenced the full ANGPTL8 gene in 283 Arabs identifying two single nucleotide polymorphisms (SNPs) Rs.892066 and Rs.2278426 in the coding region. Our data shows for the first time that Arabs with the heterozygote form of (c.194C > T Rs.2278426) had higher level of Fasting Blood Glucose (FBG) compared to the CC homozygotes. LDL and HDL level in these subjects did not show significant difference between the two subgroups. Circulation level of ANGPTL8 did not vary between the two forms. No significant changes were observed between the various forms of Rs.892066 variant and FBG, LDL or HDL.\Question: Is aNGPTL8/Betatrophin R59W variant associated with higher glucose level in non-diabetic Arabs living in Kuwaits?
Our data shows for the first time that heterozygote form of ANGPTL8 Rs.2278426 variant was associated with higher FBG level in Arabs highlighting the importance of these variants in controlling the function of betatrophin.
