Detailed Document
Overview of Gene Research
MiR-690 is a microRNA that has been implicated in multiple biological processes. It is involved in regulating insulin sensitivity, with a potential role in metabolic disease [1,2,3]. It also appears to play a part in the etiology of non-alcoholic steatohepatitis (NASH) [2].
In functional studies, miR-690 in M2-polarized macrophages is highly expressed in exosomes and improves insulin sensitivity in obese mice by targeting Nadk, which modulates macrophage inflammation and insulin signaling [1]. In NASH, Kupffer cells produce miR-690 and its deficiency promotes NASH pathogenesis. Administration of an miR-690 mimic robustly inhibits NASH features [2].
In conclusion, miR-690 is crucial in maintaining normal metabolic homeostasis, especially in relation to insulin sensitivity and NASH. The gene knockout (KO) or conditional knockout (CKO) mouse models used in these studies have been instrumental in revealing its role in these disease-related biological processes, offering potential therapeutic avenues for metabolic diseases like NASH and those associated with insulin resistance.
