However, differential expression of LINC02615 wasnot significantly related to HER2 and PR expressionas well as stage, grade and size of the tumor (P=0.439,P=0.083, P=0.078, P=0.08 and P=0.252 respectively).Moreover, difference of LINC02615 expressionwas not significantly associated with family historyof breast cancer, income, marital age, age at firstpregnancy, breastfeeding history and birth control pillsas well as dietary factors including fat, red meat anddairy intakes (P=0.273, P=0.209, P=0.473, P=0.448,P=0.067, P=0.338, P=0.621, P=0.387 and P=0.121,respectively). This evidence concerns the gene PGR and breast cancer.
