T1 | 0-108 | Sentence | denotes | Cyclooxygenase-2 enzyme induces the expression of the α-2,3-sialyltransferase-3 (ST3Gal-I) in breast cancer. |
T2 | 109-172 | Sentence | denotes | Aberrant glycosylation is a common feature of malignant change. |
T3 | 173-390 | Sentence | denotes | Changes in mucin-type O-linked glycosylation in breast cancer can result in the expression of truncated core 1-based sialylated glycans rather than the core 2-based glycans observed in normal mammary epithelium cells. |
T4 | 391-540 | Sentence | denotes | This has been shown, in part, to be due to changes in the expression of glycosyltransferases, including the up-regulation of some sialyltransferases. |
T5 | 541-869 | Sentence | denotes | Using the breast cancer cell line T47D, we have shown that PGE2, one of the final products of the cyclooxygenase-2 (COX-2) pathway, can induce the mRNA expression of the sialyltransferase α-2,3-sialyltransferase-3 (ST3Gal-I), resulting in increased sialyltransferase activity, demonstrated by a reduction in PNA lectin staining. |
T6 | 870-1069 | Sentence | denotes | Induction of COX-2 in the MDA-MB-231 breast cancer cell line also results in the increased expression of ST3Gal-I, leading to increased sialylation of the substrate of ST3Gal-I, core 1 Galβ1,3GalNAc. |
T7 | 1070-1158 | Sentence | denotes | This effect on sialylation could be reversed by the selective COX-2 inhibitor celecoxib. |
T8 | 1159-1312 | Sentence | denotes | The use of siRNA to knock down COX-2 and overexpression of COX-2 in MDA-MD-231 cells confirmed the involvement of COX-2 in the up-regulation of ST3Gal-I. |
T9 | 1313-1458 | Sentence | denotes | Moreover, analysis of the expression of ST3Gal-I and COX-2 by 74 primary breast cancers showed a significant correlation between the two enzymes. |
T10 | 1459-1601 | Sentence | denotes | COX-2 expression has been associated with a number of tumors, including breast cancer, where its expression is associated with poor prognoses. |
T11 | 1602-1812 | Sentence | denotes | Thus, these results suggest the intriguing possibility that some of the malignant characteristics associated with COX-2 expression may be via the influence that COX-2 exerts on the glycosylation of tumor cells. |

T1 | 0-108 | Sentence | denotes | Cyclooxygenase-2 enzyme induces the expression of the α-2,3-sialyltransferase-3 (ST3Gal-I) in breast cancer. |
T2 | 109-172 | Sentence | denotes | Aberrant glycosylation is a common feature of malignant change. |
T3 | 173-390 | Sentence | denotes | Changes in mucin-type O-linked glycosylation in breast cancer can result in the expression of truncated core 1-based sialylated glycans rather than the core 2-based glycans observed in normal mammary epithelium cells. |
T4 | 391-540 | Sentence | denotes | This has been shown, in part, to be due to changes in the expression of glycosyltransferases, including the up-regulation of some sialyltransferases. |
T5 | 541-869 | Sentence | denotes | Using the breast cancer cell line T47D, we have shown that PGE2, one of the final products of the cyclooxygenase-2 (COX-2) pathway, can induce the mRNA expression of the sialyltransferase α-2,3-sialyltransferase-3 (ST3Gal-I), resulting in increased sialyltransferase activity, demonstrated by a reduction in PNA lectin staining. |
T6 | 870-1069 | Sentence | denotes | Induction of COX-2 in the MDA-MB-231 breast cancer cell line also results in the increased expression of ST3Gal-I, leading to increased sialylation of the substrate of ST3Gal-I, core 1 Galβ1,3GalNAc. |
T7 | 1070-1158 | Sentence | denotes | This effect on sialylation could be reversed by the selective COX-2 inhibitor celecoxib. |
T8 | 1159-1458 | Sentence | denotes | The use of siRNA to knock down COX-2 and overexpression of COX-2 in MDA-MD-231 cells confirmed the involvement of COX-2 in the up-regulation of ST3Gal-I. Moreover, analysis of the expression of ST3Gal-I and COX-2 by 74 primary breast cancers showed a significant correlation between the two enzymes. |
T9 | 1459-1601 | Sentence | denotes | COX-2 expression has been associated with a number of tumors, including breast cancer, where its expression is associated with poor prognoses. |
T10 | 1602-1812 | Sentence | denotes | Thus, these results suggest the intriguing possibility that some of the malignant characteristics associated with COX-2 expression may be via the influence that COX-2 exerts on the glycosylation of tumor cells. |
