Abstract We studied the effect of serum folate-binding protein (FBP) on folate radioassays and the relationship of the serum level of unsaturated FBP to the serum folate level in various clinical states. Our modification of a heat-extracted radioassay was compared to a whole serum radioassay. Our results confirmed the existence of elevated serum levels of unsaturated FBP in some normal subjects, in some women taking oral contraceptives, and in most patients with uremia. Elevated levels of unsaturated FBP will produce falsely low results in folate radioassay unless the FBP has been destroyed by heat, as was done in the modified radioassay here presented. In normal and uremic subjects, serum folate and unsaturated FBP levels tended to correlate, whereas in patients taking large doses of folic acid the level of unsaturated FBP fell as the level of serum folate rose.

Translational efficiency of a minor group of mRNAs is regulated by serum levels in 3T6 fibroblasts. Included within this group is the poly(A)-binding protein (PABP) mRNA. We analyzed the distribution of PABP mRNA in polysome profiles and found a large percentage of this mRNA to be translationally repressed in both actively growing (~ 60%) and resting cells (~ 70%). Elevated serum levels induced a distinct bimodal distribution of this mRNA between actively translated and repressed fractions. Similarly, treatment of cells with low doses of cycloheximide also generated a partial shift of repressed PABP mRNA into the actively translated fraction. In an attempt to characterize the factors which regulate PABP mRNA translation we have identified the proteins which bind to this mRNA in vitro. Sequences within the 5′ untranslated region were found to be sufficient for binding of all proteins to this mRNA. We suggest that this region and the proteins associated with it may be essential for translation control of PABP mRNA.Key words: translation, mRNP, poly(A) binding protein.

Abstract Background Galectin-3 binding protein (GAL-3BP) is one of the major fucosylated glycoprotein family members, and is implicated in nonalcoholic fatty liver disease, lipid dysfunctions and coronary artery disease recently. Here we analyzed the serum concentrations of GAL-3BP in postmenopausal women, to evaluate the association of circulating GAL-3BP and insulin resistance in female after menopause. Method We evaluated serum levels of Gal-3BP in sixty-two non-diabetic women in menopausal status for at least one year. The clinical features, biochemistry profiles and homeostasis model assessment of insulin resistance (HOMA-IR) were obtained routinely. Results Gal-3BP levels increased in women with higher HOMA-IR values and was positively correlated to HOMA-IR. It was also an independent risk factors for HOMA-IR and showed the most influence on HOMA-IR comparing to FPG, TG, age and BMI. The cut-off value of serum Gal-3BP level was 2234.3150 ng/ml with the area under the ROC curve (AUC) 0.68 (HOMA-IR 1.5), 0.81 (HOMA-IR 2.0) and 0.93 (HOMA-IR 2.5). Conclusions Serum levels of Gal-3BP is associated with impaired insulin sensitivity in non-diabetic menopausal women.

Abstract Objectives There is no reliable and valid biomarker to identify Irritable bowel syndrome (IBS) and its subtypes. The aim of this study is to explore potential serum biomarkers that may be associated with IBS subtypes, particularly in the vitamin D pathway. Methods The study population comprised 75 IBS patients and 79 controls. Patients divided into IBS subtypes. Routine biochemical parameters, 25-OH-vitamin D, vitamin D binding protein (VDBP) and vitamin D receptor (VDR) serum levels were compared between IBS subtypes and controls. Factors related to IBS subtypes were examined by multivariate logistic regression analysis. Results Vitamin D levels were lower; VDBP and VDR were higher in all IBS patients than in controls (p<0.001; 0.047 and 0.029, respectively). According to logistic regression analysis, VDBP was a disease-related parameter as much as vitamin D in all IBS subtypes. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were higher especially in diarrhea-dominant IBS (IBS-D) (p=0.041; 0.046) and vitamin B12 were significantly lower in constipation-dominant IBS (IBS-C) (p=0.001). Conclusions Increased VDBP levels were associated with all IBS subtypes. Patients, especially in IBS-D, had higher serum levels of VDBP, CRP and ESR. Vitamin B12 deficiency, which we consider as a result of the disease, was more common in IBS-C.
