Serum samples from the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study were used in a nested case control study to identify the possible association between the serum level of epidermal growth factor receptor and p53 in respect to lung cancer. The proteins were assayed for by commercial immunoassays that showed uneven, often unacceptable, quality. For EGFR there was no relationship to lung cancer. Two physiological variables appeared to modify the serum level of EGFR, age by decreasing it annually by about 4 fmolml-1, and stroke by increasing it by 150 fmolml-1. For p53, myocardial infarction appeared to cause an increase in serum levels of this protein. While the serum levels of p53 were only moderately increased in lung cancer patients, particularly those with squamous cell carcinoma, the intriguing findings related to the high frequency of p53-positive patients among those belonging to the group of patients being treated by surgery and those belonging to clinical stages 1 and 2 as compared with higher clinical stages. An untested rationalization of these results was that patients with advanced lung cancer, stages 3 and higher, develop autoantibodies against the mutant p53 and thus mask the serum levels of the mutant p53 protein. 相似文献

The OVX1 tumor marker promises to complement CA125 for detection of early stage ovarian carcinoma. OVX1 has also been shown to be elevated in colon cancer patients. This study is designed to assess serum OVX1 levels in patients with specific stages of colon cancer, colon polyps or other GI disorders. Serum OVX1 and CEA were measured by radioimmunoassay or enzyme immunoassay for 206 patients at the time of colonoscopy or staging for colon carcinoma. In patients with stage I, II, III, or IV colon carcinoma, serum OVX1 was positive in 37%, 48%, 74% and 63%, respectively. Fifty-three percent of patients with colon polyps had elevated OVX1 levels, while OVX1 levels were positive in only 7% of healthy controls. If both OVX1 and CEA were considered, at least one of these markers was elevated in 36%, 60%, 79% or 89% of patients with stage I, II, III or IV colon carcinoma, respectively. The majority of patients with inflammatory bowel disease or diverticulosis also had elevated OVX1 levels. Both markers were positive in 27% of patients with colon carcinoma, and not in any patients with a normal colonoscopy or with a diagnosis of diverticulosis or hemorrhoids. In conclusion, serum OVX1 improves the sensitivity of CEA for detecting colon polyps and colon cancer; however, the use of OVX1 in this setting is hindered by its elevation in non-malignant colonic processes. 相似文献

Tumor markers known to date are not sensitive and specific enough to detect malignant tumors. Therefore, attempts to find new markers have led to sialic acid assays in cancer patients. Serum sialic acid, CEA and ESR have been determined in 33 patients with the cancer of the colon. All patients have been divided into four groups, according to TNM cancer staging. Serum sialic acid levels have been increased by 100% of patients in groups I and IV. The most significant correlation was noted between sialic acid levels and ESR. No significant relationship between serum sialic acid and CEA have been noted. No correlation of the colon cancer stage, according to TNM staging, and sialic acid and CEA levels in the peripheral blood has been observed. It seems, however, that serum sialic acid assay may be useful auxiliary technique in the detection and monitoring of patients with colon cancer. 相似文献

Since low selenium (Se) levels have been identified in some individuals with colon cancer, we evaluated Se levels as a potential marker for this malignancy in a kindred subject to hereditary nonpolyposis colorectal cancer, an autosomal dominant disease. Unaffected family members and spouses were selected randomly for testing. Serum Se levels were performed on dialyzed sera using the neutron activation technique. Hair Se assays were determined by a spectrofluorometric method. Family members were classified as having low, intermediate, or high risk for colon cancer based on family history. There was no correlation between serum and hair Se measurements. There was also no significant difference in hair or serum Se levels between any of the groups, suggesting that serum Se levels do not correlate with hereditary risk for colon cancer. Prospective studies are in progress to evaluate tissue Se levels and serial Se measurements in high risk patients to establish whether Se levels change with the development of colon cancer. 相似文献

Serum amyloid A (SAA) is an acute phase reactant, whose level in the blood is elevated in response to trauma, infection, inflammation, and neoplasia. Elevated levels of SAA in the serum of cancer patients were suggested to be of liver origin rather than a tumor cell product. The role of SAA in human malignancies has not been elucidated. We investigated the expression of SAA at various stages of human colon carcinoma progression. Nonradioactive in situ hybridization applied on paraffin tissue sections from 26 colon cancer patients revealed barely detected SAA mRNA expression in normal looking colonic epithelium. Expression was increased gradually as epithelial cells progressed through dysplasia to neoplasia. Deeply invading colon carcinoma cells showed the highest levels of SAA. Expression was also found in colon carcinoma metastases. Cells of lymphoid follicles of the intestinal wall, inflammatory cells, ganglion cells, and endothelial cells, also expressed SAA mRNA. Immunohistochemical staining revealed SAA protein expression that colocalized with SAA mRNA expression. RT-PCR analysis confirmed the expression of the SAA1 and SAA4 genes in colon carcinomas, expression that was barely detectable in normal colon tissues. These findings indicate local and differential expression of SAA in human colon cancer tissues and suggest its role in colonic tumorigenesis. 相似文献

There have been inconsistent reports on the relationship between iron status and coronary artery diseases (CAD), and little data on this relationship in non-Caucasian populations. We assessed dietary iron by questionnaire and measured serum iron and ferritin levels in 270 Saudi male subjects without established CAD, 130 of whom were angiogram negative. Serum lipid profile, glucose, high sensitivity-C reactive protein (hs-CRP), serum soluble intercellular adhesion molecules-1 (sICAM-1), and caeruloplasmin were measured in all subjects. The angiogram negative patients, had lower serum ferritin (p<0.05) and iron (p<0.0001) levels than the 140 subjects without reported cardiovascular diseases (CVD). Serum iron correlated with serum triglycerides (p<0.0001) and total cholesterol (p<0.05) levels for this latter group and the groups combined. Serum ferritin correlated with serum total cholesterol and low-density lipoprotein (LDL)-cholesterol in the combined group (p<0.05), and was correlated with blood glucose and serum LDL-cholesterol (p<0.05) in the subjects without reported CVD. After adjustment for confounding variables, serum iron levels remained a significant correlate with total calorie intake and serum triglycerides. Serum ferritin also correlated significantly with cholesterol intake and fasting serum total cholesterol. Dietary iron was significantly related to dietary cholesterol and fiber, age, smoking habits, and serum total cholesterol level. Hence, indices of iron status were related to several coronary risk factors in the Saudi population. 相似文献

Several human studies have shown an inverse relation between vitamin A intake (and serum concentrations of retinol and carotene) and cancer. Serum cholesterol concentrations have also been reported in inverse relation to cancer. In a study of 3102 people in Evans County, Georgia, who were followed for over 12-14 years to assess the incidence of cancer there was an inverse association between the risk of cancer and both serum retinol and serum cholesterol concentrations. The data also showed an unexpectedly strong correlation between serum retinol and total cholesterol concentrations. The inverse relationship with cancer was stronger with serum retinol than with cholesterol, which suggested that the association with cholesterol might be secondary. This suggestion may also explain the cholesterol-cancer association reported in several other cohort studies. Further studies of the relation between serum concentrations of cholesterol, retinol, and carotene and the incidence of cancer are needed. 相似文献

Type 2 diabetes mellitus is a complex metabolic disorder with adverse cardiovascular risk. The role of micronutrients has not yet been well clarified in this condition, especially in India.THE OBJECTIVES OF THIS STUDY WERE TO: (1) evaluate chromium status in Indian subjects with type 2 diabetes mellitus, (2) assess the effect of chromium picolinate (200 &mgr;g trivalent chromium twice daily) administration on glycaemic control and lipid profile in these subjects and (3) comment on the possible mechanism of any beneficial effect noted above.Fifty subjects were studied in a double blind, placebo-controlled, crossover fashion, with each treatment arm (chromium/placebo) lasting 12 weeks and 4 weeks' wash-off period in between. 50 healthy age- and sex-matched volunteers served as controls. Serum chromium level appeared to be higher in the general population in our country compared to western countries (36.5-59.5 nmol/L as compared to 2.3-40.3 nmol/L) However, the local diabetics were found to have a lower serum chromium level than the healthy controls (32.3 nmol/L against 44.7 nmol/L; p < 0.0001) and a mean increase of 3.5 nmol/L was noted after 12 weeks of chromium supplementation that was, expectedly, not seen in the placebo phase (p < 0.0001).Significant improvement in glycaemic control was noted in the chromium-treated group (DeltaFasting serum glucose = 0.44 mmol/L, p < 0.001; DeltaPost-prandial serum glucose = 1.97 mmol/L, p < 0.001; Deltaglycated hemoglobin = 0.01; p = 0.04, in comparison to placebo) This was accompanied by a significant greater fall in fasting serum insulin in the chromium-treated group, p < 0.05.The change in lipid parameters (total serum cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol and triglycerides) did not show significant difference between the chromium and placebo groups.Clinically significant hematological, renal or hepatic toxicity were excluded by routine hemogram, serum urea, creatinine, alanine amino transferase (ALT) and alkaline phosphatase estimations.In conclusion, chromium supplementation seems to improve glycaemic control in type 2 diabetic patients, which appears to be due to an increase in insulin action rather than stimulation of insulin secretion. 相似文献

BackgroundVitamin D deficiency is repeatedly reported in colorectal cancer (CRC). Since cholesterol and vitamin D share common precursor 7-dehydrocholesterol (7-DHC), it would be important to explore the associations of key vitamin D metabolites and serum lipid parameters in patients with high and low grade CRC. The aim of this study was to analyze relationships between serum 25(OH)D3, 24,25(OH)2D3 and 7-DHC levels and serum lipids in patients with CRC, and to evaluate their potential for prediction of risk for development of high grade CRC. MethodsWe recruited 82 patients CRC and 77 controls. 7-DHC, 25(OH)D3 and 24,25(OH)2D3 were quantified by LC-MS/MS methods. Results7-DHC, 25(OH)D3 and vitamin D metabolic ratio (VDMR) were significantly lower in CRC patients than in control group (P<0.001, P<0.010, P<0.050 and P<0.050, respectively). 25(OH)D3 levels were higher in patients with grade I CRC when compared to grade II (P<0.050). All vitamin D metabolites positively correlated with total cholesterol (TC) concentration in CRC patients. 25(OH)D3 was significant predictor of increased CRC risk (P<0.010). After adjustment for TC concentration, 25(OH)D3 lost its predictive abilities. However, 25(OH)D3 remained significant predictor of poorly differentiated type of cancer (P<0.050). ConclusionsWe found significant positive association between vitamin D status and serum total cholesterol. Although low 25(OH)D3 was found to be a significant risk factor for CRC development, the obtained results primarily suggest profound impact of cholesterol level on vitamin D status in CRC. However, our results suggest that low 25(OH)D3 might independently contribute to development of poorly differentiated tumor. 相似文献

ObjectiveTo investigate the changes of serum leptin, lipid levels, adiponectin, NO and TNF-α in patients withnon-traumatic ischemic necrosis of the femoral head of the femoral head and its meanings. MethodsA total of 80 patients with ischemic necrosis of the femoral head were selected from January 2015 to January 2016. And 30 healthy volunteers who took the same time were selected as the control group. Both subjects were given venous blood in the morning fasting. Serum leptin levels were measured by radioimmunoassay. Serum lipids, high and low density lipoprotein, cholesterol, triglyceride and apolipoprotein A1 were detected by automatic biochemical analyzer. Apolipoprotein B was measured by radioimmunoassay. The levels of serum adiponectin were measured by radioimmunoassay. The levels of NO and TNF-α in serum were measured by enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the control group, the levels of cholesterol, triglyceride level, middle and low density lipoprotein and apolipoprotein B were significantly increased in INFH serum; the levels of high density lipoprotein and apolipoprotein A1 were significantly decreased The contents of NO and TNF-α were significantly increased, the content of adiponectin was significantly decreased. There was significant difference between the two groups ( P < .05). ConclusionThe levels of serum cholesterol, triglyceride level, low density lipoprotein level, apolipoprotein B level, leptin, NO and TNF-α levels in serum of INHF patients were positively correlated with the condition of INHF patients, and high density lipoprotein levels, Apolipoprotein A1 levels and adiponectin levels were negatively correlated with INHF patients. 相似文献

BACKGROUND: Both interleukin-18 and nitric oxide are multifunctional molecules that are involved in the different steps of carcinogenesis. METHODS: In the present study, we measured serum interleukin-18 and nitric oxide activity in 51 bladder cancer patients with different tumor stage and grade, and in 8 healthy controls. Serum nitrite-nitrate levels were measured as an index of nitric oxide generation. RESULTS: Serum interleukin-18 levels were significantly higher in bladder cancer patients when compared to the control subjects (p > 0.05). Serum interleukin-18 levels were found to be higher in patients with Ta stage than patients with T1 and T2, T3, T4 stages and in patients with grade 1 tumors than patients with grade 2 and grade 3 tumors, but this was not statistically significant (p > 0.05). There was no significant difference in serum nitrite + nitrate levels between bladder cancer patients and control subjects. CONCLUSIONS: Elevated serum interleukin-18 levels in bladder carcinoma patients may be a result of host defence mechanism against the growth and progression of bladder cancer cells. 相似文献

Serum lathosterol concentration in rabbits was assessed as a possible indicator of whole-body cholesterol synthesis. In random-bred New Zealand White (NZW) rabbits fed a control diet or a diet containing either cholesterol, simvastatin, or cholestyramine, neither serum lathosterol concentration nor the serum lathosterol:total cholesterol ratio systematically corresponded with the anticipated rate of cholesterol synthesis. In control rabbits and those fed simvastatin or cholestyramine, whole-body cholesterol synthesis, which was calculated from the sterol balance, was correlated with serum lathosterol concentration when expressed relative to cholesterol in very low, intermediate, and low density lipoproteins (VLDL + IDL + LDL) (r = 0.61; n = 23; P = 0.002). The low correlation coefficient indicates that the predictive value of the lathosterol: (VLDL + IDL + LDL) cholesterol ratio is limited when applied to individual rabbits. Cholesterol and simvastatin feeding reduced the group mean serum lathosterol:(VLDL + IDL + LDL) cholesterol ratio, whereas cholestyramine in the diet raised the group mean ratio in the NZW rabbits. We conclude that the serum lathosterol:(VLDL + IDL + LDL) cholesterol ratio may be an indicator of group mean rates of whole-body cholesterol synthesis in rabbits but may not yield reliable information on individual rabbits. The lathosterol:(VLDL + IDL + LDL) cholesterol ratio predicted that in hyperresponsive inbred rabbits, showing an excessive hypercholesterolemia after cholesterol feeding, baseline whole-body cholesterol synthesis is lower than in hyporesponsive rabbits. Addition of cholesterol to the diet caused a reduction of predicted cholesterol synthesis in hypo- but not in hyper-responsive rabbits. 相似文献

Tamoxifen, the widely prescribed drug in the prevention and therapy of breast cancer, may cause side effects which may be
influenced by gender. The present study was undertaken to investigate the impact of gender on tamoxifen-induced toxic and
biochemical changes following oral administration of tamoxifen at high dose level of 20 mg/kg once daily for a 2-week period
in both male and female rats. The results showed marked increases in serum activities of alanine aminotransferase (ALT) and
aspartate aminotransferase (AST) in female rats. In contrast, treatment with tamoxifen in male animals significantly decreased
the activity of ALT, with a tendency for a decrease in serum AST levels. In female rats, a significant reduction in the serum
activity of acid phosphatase (ACP) was noted, compared with a non-significant decrease in males. Non-significant changes in
serum levels of alkaline phosphatase (ALP) were seen in both sexes. Tamoxifen lowered serum contents of total lipid and total
cholesterol in both male and female rats. Serum levels of triglycerides were reduced in female rats as compared to a non-significant
decrease in male animals. The serum albumin concentration was decreased in both male and female rats, while total protein
was decreased only in female animals. Tamoxifen markedly increased serum levels of creatinine in female rats, compared with
a non-significant rise in males. Total serum contents of calcium were similarly reduced in both males and females. This is
the first study which points to gender-related differences in tamoxifen-induced toxic and metabolic changes in rats. The results
indicated that females are more susceptible than males to tamoxifen toxicity, probably due to the ability of tamoxifen to
antagonize the action of estrogen in females. 相似文献
