Correlation analysis between serum FOXP1 and CDK2 levels and the occurrence of osteoporosis in perimenopausal women / 中华内分泌外科杂志

ABSTRACT

Objective:To investigate the correlation between serum forkhead box protein P1 (FOXP1) and cyclin-dependent kinase2 (CDK2) and bone mineral density in perimenopausal women with osteoporosis (OP) .Methods:A total of 80 perimenopausal women treated in our hospital from Feb. 2021 to Aug. 2022 were selected as study objects. Among them, 38 were in the OP group and 42 were in the control group. The expression levels of FOXP1 and CDK2 in serum were detected by ELISA. BMD expression levels of lumbar spine (L1-L4) and femoral neck were measured by DEXA BMD analyzer. The correlation between serum FOXP1 and CDK2 and bone mineral density in perimenopausal women with osteoporosis was analyzed by Pearson method.Results:Compared with the control group, the contents of FOXP1 and CDK2 in serum of the control group were (42.94±3.37) pg/ml and (102.46±12.247) pg/ml, respectively. Serum FOXP1 and CDK2 contents in OP group were (25.91±4.38) pg/ml and (60.59±10.777) pg/ml, respectively. Compared with the control group, serum FOXP1 and CDK2 expression levels and bone mineral density of lumbar spine (L1-L4) and femoral neck in OP group were significantly decreased. The BMD of lumbar spine (L1-L4) and femoral neck of women in the control group were 0.68±0.28 and 0.43±0.99, respectively. BMD of lumbar spine (L1-L4) and femoral neck of women in the OP group were 0.40±0.10 and 0.21±0.15, respectively. Bone mineral density decreased in the lumbar spine (L1-L4) and femoral neck in the OP group. The differences were statistically significant ( P<0.05). In addition, the correlation analysis results showed that the expression level of FOXP1 in serum was positively correlated with bone mineral density of lumbar spine (L1-L4) and femoral neck ( r=0.546, 0.245, P<0.05), and the expression level of CDK2 was positively correlated with bone mineral density of lumbar spine (L1-L4) ( r=0.600, P<0.05) . Conclusions:In perimenopausal women with osteoporosis, the expression of FOXP1 and CDK2 in serum was significantly decreased, and there was a correlation with bone mineral density. It is suggested that FOXP1 and CDK2 may be used as biological indicators and clinical predictors of osteoporosis in perimenopausal women.
