Utp14a, also known as U three protein 14a, is an essential component of a large ribonucleoprotein complex. It is involved in ribosome biogenesis, as it activates the RNA helicase DHX37 to facilitate maturation of the small ribosomal subunit [4]. Moreover, it is associated with multiple cellular regulatory pathways and has significant biological importance in processes such as cell proliferation, angiogenesis, and tumorigenesis. Genetic models can be valuable for studying its functions in vivo.

In obesity-induced cardiac injury, Utp14a was identified as a hub gene. Obesity-related pathological changes in the heart, like increased collagen fibers and decreased microvessel proliferation, may be modulated by Utp14a along with other genes, potentially affecting cardiac microcirculatory function [1]. In colorectal cancer, knockdown of hUTP14a (human Utp14a) impairs tube formation and migration of endothelial cells, indicating its role in promoting angiogenesis by upregulating PDGFA expression [2]. In esophageal squamous cell carcinoma, knockdown of Utp14A suppresses cell migration and proliferation, suggesting it promotes tumor proliferation and metastasis via the PERK/eIF2a/GRP78 signalling pathway [3].

In conclusion, Utp14a plays crucial roles in ribosome biogenesis, angiogenesis, and tumor-related processes. Model-based research, especially loss-of-function experiments in relevant disease models such as obesity-induced cardiac injury, colorectal cancer, and esophageal squamous cell carcinoma, has revealed its significance in these biological functions and disease conditions. Understanding Utp14a provides insights into the underlying mechanisms of these diseases, potentially offering new strategies for treatment.
