Comparison of gene expression between SDR and HHR mammary glands tissue

To examine whether factors responsible for early involution of HHR mammary gland are different from those involved in physiologic involution of the SDR tissue, gene expression profiles of HHR tissue at lactation day 1 and SDR tissue at involution day 1 were evaluated by microarray analysis为探究调控HHR乳腺早期退化的相关因子与SDR组织生理性退化的调控因子是否存在差异，本研究通过微阵列分析（microarray analysis），对泌乳第1天的HHR组织与退化第1天的SDR组织的基因表达谱（gene expression profiles）进行了评估。
