Cpne7, also known as Copine7, is a gene with significant roles in various biological processes. It is involved in supporting periodontal attachment and alignment, and plays a part in the maintenance and homeostasis of odontoblasts, promoting their differentiation from progenitor cells [1,2]. It may also be associated with the amyloidogenic pathway in Alzheimer's disease by regulating ADAM10 translation [4]. Genetic models, such as KO/CKO mouse models, are valuable for studying its functions.

In Cpne7-null dental pulp, cellular senescence in odontoblasts is accelerated due to oxidative stress and DNA damage accumulation, impairing odontoblast survival and leading to aberrant dentin formation [1]. In contrast, Cpne7-overexpressing transgenic mice show a healthy dentin-pulp complex and the ability to regenerate physiologic dentin in artificial defects [1]. In colorectal cancer, Cpne7 is highly expressed and promotes cancer cell proliferation and metastasis. Knockdown of Cpne7 inhibits these processes, highlighting its oncogenic role [3,5,6].

In conclusion, Cpne7 is essential for maintaining the function of odontoblasts and periodontal tissues, and its dysregulation is associated with colorectal cancer. Gene knockout mouse models have been crucial in revealing its role in age-related dental diseases and colorectal cancer, providing insights into potential therapeutic targets for these conditions.
