The relationship of CCL4, BCL2A1, and NFKBIA genes with premature aging in women of Yin deficiency constitution.

BACKGROUND

Traditional Chinese Medicine (TCM) defined constitution as a health statue or physical fitness that determines individual susceptibility to diseases. Yin deficiency constitution (YinDC) is a type of constitution closely related to aging. Previous studies found that the characteristic genes of YinDC are part of the inflammatory aging signaling pathways (e.g., NF-kappa B). Therefore, the aim of the study was to further reveal the dysregulation of genes associated with inflammatory aging in YinDC women.

METHODS

This study adopted the industrial standard of constitutional judgment, and screened YinDC (n = 30) and Balanced constitution (BC) (n = 30) from women between the ages of 35 to 49, a range categorized as the degenerating period by TCM. Five genes CCL4, BCL2A1, NFKBIA, TAK1, and IL-8 were analyzed by qRT-PCR.

RESULTS

Logistical regression revealed the correlation between body constitution and the expression of the five genes: the expression of NFKBIA and CCL4 mRNA was significantly up-regulated, whereas the expression of BCL2A1 mRNA was significantly down-regulated in YinDC (P < 0.05). Age or weight, when included in the model, did not affected the correlations.

CONCLUSION

Increased mRNA expression of CCL4 and NFKBIA and decreased mRNA expression of BCL2A1 may be the molecular basis of premature aging of YinDC women. These results provide a mechanistic basis for early conditioning of YinDC, anti-aging, and the prevention of aging-related diseases.
