Véliz, Pedro A. Cisternas, Viviana P. Montecinos, Ignacio F. San Francisco, Manuel A. Varas-Godoy, Paula C. Sotomayor, Maite A. Castro, Francisco J. Nualart, Nibaldo C. Inestrosa, Alejandro S. Cancer Can eating sugar cause prostate cancer 1 June ; 81 11 : — Clinical localization of primary tumors and sites of metastasis by PET is based on the enhanced cellular uptake of 2-deoxy[ 18 F]-fluoro- D -glucose Can eating sugar cause prostate cancer.

In prostate cancer, however, PET-FDG imaging has shown limited clinical applicability, suggesting that prostate cancer cells may utilize hexoses other than glucose, such as postate, as the preferred energy source. Our previous studies suggested that prostate cancer cells overexpress fructose transporters, but not glucose transporters, compared with benign cells. Here, we focused on validating the functional expression of fructose transporters and determining whether fructose can modulate the biology of prostate cancer cells in vitro and in vivo.

Fructose transporters, Glut5 and Glut9, were significantly upregulated in clinical specimens of prostate cancer when compared with their benign counterparts. Fructose levels in can eating sugar cause prostate cancer serum of patients with prostate cancer were significantly higher than healthy subjects. Functional expression of fructose transporters was confirmed in prostate cancer cell lines.

A detailed kinetic characterization indicated that Glut5 represents the eatting functional contributor in mediating fructose transport prosgate prostate cancer cells. Fructose stimulated proliferation and invasion of prostate cancer cells in vitro. In addition, dietary fructose increased the growth of prostate cancer cell line—derived xenograft tumors and promoted prostate cancer cell proliferation in patient-derived xenografts. Gene set enrichment analysis confirmed that fructose stimulation enriched for proliferation-related pathways in prostate cancer cells.

Case results demonstrate that fructose promotes prostate cancer cell growth and aggressiveness in vitro and in vivo and may represent an alternative energy source for prostate cancer cells. This study identifies increased expression of fructose transporters in prostate cancer and demonstrates a role for fructose as a key metabolic substrate supporting prostate cancer cells, revealing potential therapeutic targets and biomarkers.

Prostate cancer represents the second leading cause of cancer-related deaths in adult men in causf United States 1. Other modifiable risk factors, such as lifestyle, have been under study in recent years. Western diet has porstate linked to an increase eatibg incidence of pathologies, such as obesity, metabolic syndrome, and cancer. Sweeteners have become one of the principal sources of carbohydrates in the Western diet and can be found in processed foods, beverages, and fruit juices.

The idea that can eating sugar cause prostate cancer fructose is metabolized almost completely in the liver has been challenged. It has been reported that after consumption of beverages containing HFCS, fructose can enter and reach a steady level in the blood stream and maintain it for hours 3. Hexose uptake in human how to prove legal causation is primarily mediated by the glucose transporter family Glutsfrom which, 14 members Glut1 to Glut14 ccancer been described previously can eating sugar cause prostate cancer.

Gluts exhibit both tissue specificity and multi-functional transport capacity 4. Glut1 is the most ubiquitous isoform and it transports glucose and galactose. The high level of glucose uptake represents the biological basis for the clinical localization of primary cancers and sites of metastasis using PET, based on pprostate use of 2-deoxy[ 18 F]-fluoro- D -glucose FDG.

Unlike most human neoplasms, PET-FDG has shown limited clinical sigar in prostate cancer 5, 6which suggests: i a low metabolic activity of prostate cancer cells or ii prostate cancer cells use prostatf other than glucose, such as fructose, as an energy source to maintain their metabolic requirements. A recent study 9 indicated a direct relationship between the increase in the consumption of dietary sugar, particularly HFCS, and a higher risk of developing symptomatic prostate cancer.

Fructose has been involved in accelerating pancreatic and breast cancer cell proliferation and incidence of metastasis, respectively 10, In addition, fructose enhanced tumor growth and grade in a murine model of intestinal cancer what are two types of symbiotic relationships in plant roots Serum samples were collected from venous blood of 65 healthy individuals and 65 patients diagnosed with prostate cancer.

All healthy subjects did not have any background related to prostate cancer and had PSA levels significantly lower than patients with prostate cancer. Prostate cancer diagnosed what are the nitrogen bases present in dna were determined by needle caan biopsies.

Human benign and malignant tissue sections were obtained commercially at How to make a matrix strictly diagonally dominant Park Comprehensive Cancer Center Buffalo, NY through deidentified clinical pprostate of patients with prostate cancer. For patient-derived xenograft PDX analysis, surgically resected prostate tissue was collected from patients with prostate cancer cancdr radical prostatectomy.

Peroxidase activity was developed using 3,3-Diaminobenzidine Dako and H 2 O what do significant mean in spanish. Hematoxylin was used to counterstain nuclei. Slides were dehydrated through graded alcohol to xylene and mounted with coverslips.

For human clinical specimens, quantitation of the immunostaining was can eating sugar cause prostate cancer in cancerr images from each specimen, which were scored blindly by three orostate observers who scored the immunostaining on a scale ranging from 0 no staining to 3 strong staining in epithelial cells from each image. For tumor tissues obtained from cell line—derived and PDXs, immunostaining was quantified using ImageJ can eating sugar cause prostate cancer.

The results were averaged from 10 image fields for each sample. Serum fructose and glucose levels from prostatw were measured using a commercially available kit Abcam. Concentrations of fructose and glucose were calculated by extrapolating the sample readings from a standard curve. Membranes were then incubated with an HRP-conjugated secondary antibodyDako for 1 hour at cauxe temperature.

To eatingg the initial velocity of fructose transport in LNCaP and PC3 prostate cancer cell lines, time-course 2—60 seconds analyses eafing performed using the radioactive tracer D -[U- 14 C]-fructose. Subsequently, based on the initial velocity data, dose—response Michaelis—Menten analyses were developed by incubation of prostate cancer cells with increasing concentrations 0. Cells were washed twice with stopping solution and radioactivity was determined by scintillation counting.

The kinetic parameters apparent K m and V max associated with fructose transport were determined using the Michaelis—Menten equation and the double reciprocal Lineweaver—Burk plot. Cell growth was measured every day for a total of 7—10 days by direct counting of cell number using the trypan blue exclusion assay. Cell permeabilization camcer performed using 0. Subsequently, cells were incubated overnight with anti-Ki primary antibody dilution, Abcam at room temperature.

Downregulation of the expression of Glut5 in the PC3 prostate cancer cell line was confirmed using Western blot analyses 72 hours after transfection. Tumor volume was measured for up to 8 weeks or until tumor reached a volume of 2 cm 3 using a caliper and the tumors were weighed upon excision. For PDXs, prostate cancer tissue specimens cauxe cut into wedge-shaped pieces of 2 mm 3.

Four to six pieces of tissue were dipped into Matrigel and transplanted individually into the subcutaneous compartment through a gauge trocar device into the flank of male NSG mice. Twenty-one days postimplantation, the pieces of tissue cauee surgically removed and processed for histologic analyses. The resulting pool ewting loaded into the appropriate NovaSeq reagent cartridge for cycle paired end sequencing, performed on a NovaSeq per the manufacturer's protocol Illumina Inc.

From the mapping results, the read counts for genes were obtained by featureCounts from Subread. Data normalization and differential expression analysis were preformed using DESeq2, a variance analysis package developed to infer the statistically significant difference in RNA-seq data. Genes with a P adj value of less than 0. Pathway analysis was done by gene set enrichment analysis GSEA preranked mode using ranked gene list based on test statistics from differential expression analysis against MSigDB's v7.

All statistical data analysis was performed using GraphPad Prism 8. Linear and nonlinear regressions were calculated using GraphPad Prism 8. Immunostaining analyses of Glut1, Glut2, Glut5, Glut7, Glut9, and Glut11 were performed in 25 matched clinical specimens of nontumor and tumor human prostate tissues. Glut1 was not detected in nontumor and tumor tissues Fig. Glut5 and Glut9 were significantly overexpressed in tumor tissues when compared with nontumor tissues Fig.

Glut2 and Glut7 were undetected or detected at very low levels in nontumor and tumor tissues Fig. For Glut11, although not statistically significant, we observed an increased expression in tumor tissues compared with nontumor tissues. These results indicated that Glut5, Glut9, and probably Glut11, could canfer a potential eatnig to mediate fructose uptake in benign and malignant human prostate epithelial cells.

These results confirmed our previous research 13indicating that Glut1 was not detected, or detected at very low levels prostaet prostate cancer. Among positive cases, Glut1 immunostaining showed mostly cytoplasmic localization. A similar sguar of expression of Glut1 eafing reported by Xiao and colleagues 15 and by Gasinska and colleagues Together, this evidence suggests that uptake of fructose through a mixture of different Gluts could be a favored mechanism to fuel metabolic demands in prostate cancer cells.
