Longevity genes and senescence-related signaling proteins are crucial targets in aging research, which aims to enhance the healthy period and quality of life. Identifying these target proteins remains challenging because of the need for precise categorization and validation methods. Our multifaceted approach combined bioinformatics with transcriptomic data to identify collagen as a key element associated with the lifespan of the model organism, . By analyzing transcriptomic data from long-lived mutants that involved mechanisms such as antioxidation, dietary restriction, and genetic background, we identified collagen as a common longevity-associated gene. We validated these findings by confirming that collagen peptides positively affect lifespan, thereby strengthening the validity of the target. Further verification through healthspan factors in and functional assays in skin fibroblasts provided additional evidence of the role of collagen in organismal aging. Specifically, our study revealed that collagen type VII is a significant target protein for mitigating age-related decline. By validating these findings across different aging models and cell-based studies, we present compelling evidence for the anti-aging effects of collagen type VII, highlighting its potential as a target for promoting healthy aging. This study proposes that collagen not only serves as an indicative marker of organismal longevity across various senescence-related signaling pathways, but also offers a mechanistic understanding of skin degeneration. Consequently, collagen is an effective target for interventions aimed at mitigating skin aging. This study underscores the potential of collagen type VII (bonding collagen T7) as a therapeutic target for enhancing skin health and overall longevity.
长寿基因和衰老相关信号蛋白是衰老研究中的关键靶点,衰老研究旨在延长健康期并提高生活质量。由于需要精确的分类和验证方法,识别这些靶蛋白仍然具有挑战性。我们的多方面方法将生物信息学与转录组数据相结合,以确定胶原蛋白是与模式生物寿命相关的关键元素。通过分析来自涉及抗氧化、饮食限制和遗传背景等机制的长寿突变体的转录组数据,我们确定胶原蛋白是一种常见的与长寿相关的基因。我们通过证实胶原蛋白肽对寿命有积极影响来验证这些发现,从而加强了靶点的有效性。通过对健康跨度因素的进一步验证以及在皮肤成纤维细胞中的功能测定,为胶原蛋白在机体衰老中的作用提供了额外证据。具体而言,我们的研究表明VII型胶原蛋白是减轻与年龄相关衰退的重要靶蛋白。通过在不同衰老模型和基于细胞的研究中验证这些发现,我们为VII型胶原蛋白的抗衰老作用提供了令人信服的证据,突出了其作为促进健康衰老靶点的潜力。这项研究提出,胶原蛋白不仅是各种衰老相关信号通路中机体长寿的指示性标志物,还提供了对皮肤退化的机制性理解。因此,胶原蛋白是旨在减轻皮肤衰老的干预措施的有效靶点。这项研究强调了VII型胶原蛋白(结合胶原蛋白T7)作为增强皮肤健康和整体寿命的治疗靶点的潜力。
