### Instruction:
Is human pregnane X receptor expressed in breast carcinomas , potential heterodimers formation between hPXR and RXR-alpha?
### Response:
|
Breast cancer cells can express both variants 1 and 2 of hPXR. Infiltrative carcinomas that recurred showed a nuclear location of both hPXR and RXR-alpha; therefore, the overexpression and the subcellular location changes of hPXR could be considered as a potential new prognostic indicator.

### Instruction:
Does altered fractalkine cleavage potentially promote local inflammation in NOD salivary gland?
### Response:
|
These data indicate that aberrant proteolytic activity in the NOD SMG results in increased fractalkine cleavage and generation of a unique fractalkine fragment. This specific cleavage may contribute to autoimmunity.
|
### Instruction:
Does secretory immunoglobulin a blunt gut-mediated priming of neutrophils in vitro?
### Response:
|
sIgA is the principal defense against potential pathogens at mucosal surfaces. Additional protective activity may be found in its ability to downregulate gut-mediated neutrophil priming. Although more work needs to be performed examining the role of sIgA in the pathogenesis of sepsis, this study shows that sIgA downregulates the measured determinants of neutrophil inflammatory potential.

### Instruction:
Are elevated serum levels of S-adenosylhomocysteine , but not homocysteine , associated with cardiovascular disease in stage 5 chronic kidney disease patients?
### Response:
|
Concentrations of serum SAH and SAM in CKD stage 5 patients are associated with renal function, but not with inflammation or PEW. Among the investigated sulfur amino acids, only SAH was independently associated with the presence of clinical signs of CVD. These findings suggest that while tHcy might be influenced by a number of confounding uremic factors, SAH levels may better reflect the putative increased cardiovascular risk of sulfur amino acid alterations in CKD patients.

Intracerebroventricular administration of NPY acutely induces insulin resistance of EGP via activation of sympathetic output to the liver.
|
### Instruction:
Is regular exercise in the elderly effective to preserve the speed of voluntary stepping under single-task condition but not under dual-task condition . A case-control study?
### Response:
|
Exercising regularly protects from physical functioning loss in older persons and against a decrease in voluntary step execution times during single-task but not during dual-task conditions. Lack of specificity (dual-task exercises) during the training may be the cause of insignificant differences in dual-task stepping performance. Thus, adding dual-task training may improve dual-task performance in the elderly.
|
### Instruction:
Does down-regulation of osteopontin suppress growth and metastasis of hepatocellular carcinoma via induction of apoptosis?
### Response:

Excess weight is more common than excessive alcohol consumption in the community and confers a greater risk of elevated aminotransaminase levels.
|
### Instruction:
Does xAF1 mRNA expression improve progression-free and overall survival for patients with advanced bladder cancer treated with neoadjuvant chemotherapy?
### Response:
|
This is one of the few studies to address the role of XAF1 in a clinical setting. The data presented here identify XAF1 as a novel predictive and prognostic factor in bladder cancer patients. Furthermore, our observations are in line with previous studies, which point towards XAF1 as a tumor-suppressor gene. Nonetheless, additional studies, both mechanistic and translational, are warranted and may help not only in corroborating the role of XAF1 as a prognostic marker, but also as a potential target for anticancer therapy.

### Instruction:
Do apolipoprotein E-/- mice have delayed skeletal muscle healing after hind limb ischemia-reperfusion?
### Response:
|
Although there was no difference between the injured muscle of Wt and ApoE(-/-) mice during the acute phase of reperfusion, ApoE(-/-) mice showed delay in skeletal muscle healing during the chronic phase of reperfusion. This lag in muscle regeneration was associated with lower levels of myogenin at 7DR and an increased level of MCP-1 at 14DR in the ApoE(-/-) mice. The delay in skeletal muscle healing in the ApoE(-/-) mice may have broader implications for poor tissue healing and functional recovery in elderly patients who have vascular risk factors such as hypercholesterolemia.
|

|
### Instruction:
Are colorectal cancer stem cells enriched in xenogeneic tumors following chemotherapy?
### Response:
|
CoCSC are enriched in colon tumors following chemotherapy and remain capable of rapidly regenerating tumors from which they originated. By focusing on the biology of CoCSC, major resistance mechanisms to specific chemotherapeutic agents can be attributed to specific genes, thereby suggesting avenues for improving cancer therapy.
|
### Instruction:
Does protein disulfide isomerase have no stimulatory chaperone effect on factor X activation by factor VIIa-soluble tissue factor?
### Response:
|
FX activation is insensitive to PDI per se and a phospholipid contaminant in the bovine PDI preparation acts stimulatory when sTF, but not lipidated TF, is the cofactor. Strong support is provided by the lacking effect of bovine PDI after removal or modification of the Gla domain in either FVIIa or FX as well as by the effects of annexin V and detergents and the decreased K(m) value.
|
### Instruction:
Is aymptomatic CMV viremia associated with increased levels of serum amyloid A in patients with advanced HIV-infection?
### Response:
|
Increased levels of SAA indicate sensitively an inflammatory response to active CMV infection. Use of a CMV-specific virological assay is required to confirm the specificity of a high SAA-level but may be limited to samples with high SAA-levels. Hence, screening for increased levels of SAA in patients with advanced HIV-infection may allow early identification of active CMV infection.
|

|
### Instruction:
Are endometrial receptivity and implantation affected by the presence of uterine intramural leiomyomas : a clinical and functional genomics analysis?
### Response:
|
This study provides evidence that intramural leiomyomas not affecting the endometrial cavity alters the expression pattern of some endometrial genes, but the genes involved in implantation are not affected. This is confirmed by leiomyomas having no effect on oocyte donation outcome when the size and number of leiomyomas are analyzed.
|
### Instruction:
Is ovarian morphology a marker of heritable biochemical traits in sisters with polycystic ovaries?
### Response:
|
These data provide further evidence for a genetic basis of PCOS. The high heritability of biochemical features in probands and affected sisters, despite wide variation in symptoms, shows that not only are these biochemical traits strongly influenced by genetic factors but also, importantly, that polycystic ovarian morphology is an index of inherited traits in families with PCOS.
|
### Instruction:

### Instruction:
Do complex molecular mechanisms cooperate to mediate histone deacetylase inhibitors anti-tumour activity in neuroblastoma cells?
### Response:
|
HDACi are therefore interesting new anti-tumour agents for targeting highly malignant tumours such as NB, as these agents display a strong toxicity toward aggressive NB cells and they may possibly reduce angiogenesis by decreasing VEGF production by NB cells.
|
### Instruction:
Does loss of the N-terminal domain of chlorophyllide a oxygenase induce photodamage during greening of Arabidopsis seedlings?
### Response:
|
The A domain of CAO regulates the level of CAO, and thus prevents the excess accumulation of chlorophyll b. This function of the A domain is especially important during the greening stage of etiolated seedlings. At this stage, the plants are vulnerable to photodamages which could be caused by excessive chlorophyll b accumulation. In addition, de-regulation of the CAO level affects monovinyl-protochlorophyllide biosynthesis in darkness by unknown mechanisms. In conclusion, the A domain of CAO is essential in the control of chlorophyll biosynthesis and in the survival of seedlings during de-etiolation especially under strong illumination.
|
### Instruction:

HPVs do not appear to play an aetiological role in cervical adenosarcomas. This suggests that a different histogenetic pathway for this rare tumour type must exist.

Is elevated Fas expression related to increased apoptosis of circulating CD8+ T cell in patients with gastric cancer?
### Response:
|
The data indicate that up-regulation of Fas expression in CD8+ T cells is related to increased apoptosis of circulating CD8+ T cells in patients with gastric cancer. Further investigations into the detailed mechanism of apoptosis induction in Fas-positive CD8+ T cells are urgently required.

### Instruction:
Is severe preeclampsia characterized by increased placental expression of galectin-1?
### Response:
|
(1) We report for the first time the placental expression and localization of galectin-1 mRNA and demonstrate that the protein is abundantly present in third trimester human placentas. (2) Placental galectin-1 expression is higher in severe PE than in normal pregnancy regardless of the presence of SGA. (3) However, it is not altered in SGA without PE. We propose that the increased placental expression of galectin-1 in patients with severe PE may represent a fetal response to an exaggerated systemic maternal inflammation; thus, galectin-1 may be implicated in maternal-fetal immune tolerance in humans.

### Instruction:
Is polycystic ovary syndrome associated with elevated plasma soluble CD40 ligand , a marker of coronary artery disease?
### Response:
|
Polycystic ovary syndrome is associated with elevated levels of sCD40L and homocysteine.

### Instruction:
Do peptidergic agonists of activity-dependent neurotrophic factor protect against prenatal alcohol-induced neural tube defects and serotonin neuron loss?
### Response:
|
These findings further support the potential usefulness of these peptides for therapeutic interventions in pregnancies at risk for alcohol-induced developmental deficits. Notably, the ascending 5-HT projections of the rostral raphe have profound effects in regulating forebrain development and function, and the descending 5-HT projections of the caudal raphe are critical for regulating respiration. Protection of the rostral 5-HT-system may help prevent structural and functional deficits linked to abnormal forebrain development, and protection of the caudal systems may also reduce the increased risk for sudden infant death syndrome associated with prenatal alcohol exposure.
