Androgenetic alopecia (AGA) stands as the most prevalent form of hair loss, affecting the hair follicles (HFs). Aging emerges as a prominent contributor in this condition. In this study, our aim is to elucidate the expression patterns of candidate genes-SIRT3, SIRT7, NFATC1, and PDL-1-known to exhibit differential expression levels during HF aging, and to underscore the role of aging in AGA.
Mesenchymal stem cells (MSCs) were isolated from the vertex and occipital regions of six men affected by AGA. The aim was to assess the expression levels of SIRT3, SIRT7, NFATC1, and PDL-1 genes. RNA extraction was performed followed by cDNA synthesis, and gene expression levels were quantified using real-time PCR. To validate the experimental findings, two different RNA-seq datasets relevant to the study were analyzed using R software.
In the present study, experimental tests revealed that the expression levels of SIRT3 and SIRT7, known to decrease during HF aging, were diminished in AGA-affected samples as well. Conversely, the mean value of NFATC1 and PDL-1 expression level, which are known to increase during HF aging, were found to be elevated in AGA-affected samples. Moreover, bioinformatic analyses provide additional support for the role of SIRT3, SIRT7 and NFATC1in AGA pathogenesis.
While SIRT3 and SIRT7 may play critical roles in AGA development, further research is needed to elucidate the significance of NFATC1 and PDL-1 in this context and to explore their potential as therapeutic targets for AGA treatment.
雄激素性脱发(AGA)是最常见的脱发形式,影响毛囊(HFs)。衰老在此种情况下是一个突出的诱因。本研究旨在阐明候选基因-SIRT3、SIRT7、NFATC1 和 PDL-1 的表达模式,这些基因在 HF 衰老过程中表现出差异表达水平,并强调衰老在 AGA 中的作用。
从 6 名患有 AGA 的男性的头顶和枕部区域分离间充质干细胞(MSCs)。目的是评估 SIRT3、SIRT7、NFATC1 和 PDL-1 基因的表达水平。进行 RNA 提取,随后进行 cDNA 合成,并使用实时 PCR 定量基因表达水平。为了验证实验结果,使用 R 软件分析了与研究相关的两个不同的 RNA-seq 数据集。
在本研究中,实验测试表明,已知在 HF 衰老过程中减少的 SIRT3 和 SIRT7 的表达水平在 AGA 受影响的样本中也降低了。相反,已知在 HF 衰老过程中增加的 NFATC1 和 PDL-1 的表达水平的平均值在 AGA 受影响的样本中升高。此外,生物信息学分析为 SIRT3、SIRT7 和 NFATC1 在 AGA 发病机制中的作用提供了额外的支持。
虽然 SIRT3 和 SIRT7 可能在 AGA 的发展中发挥关键作用,但需要进一步研究来阐明 NFATC1 和 PDL-1 在这方面的意义,并探索它们作为 AGA 治疗的潜在治疗靶点的可能性。
