Fam114a1, Family with Sequence Similarity 114 Member A1, is a gene with diverse functions. It is involved in regulating angiotensin II signaling, which is related to cardiac pathological remodeling [1]. Additionally, it may play a role in the development of cells like melanocytes, nerve cells, and those originating from the neural crest of the embryonic ectoderm [2].

In mouse models, homozygous KO of Fam114a1 reduces cardiomyocyte hypertrophy, inflammation, and cardiac fibrosis, while restoring cardiac function in angiotensin II-induced and MI-induced heart failure mouse models [1]. In melanocytes, inhibition of Fam114a1 increases proliferation, migration, and melanin synthesis proteins, and decreases apoptosis [2]. In hepatocellular carcinoma cells, suppression of Fam114a1 reduces cell proliferation and migration, promotes apoptosis, arrests the cell cycle, and inhibits epithelial-mesenchymal transition by modulating AKT1 [3].

In conclusion, Fam114a1 is a key regulator in multiple biological processes. Its knockout in mouse models has provided insights into its role in cardiac pathological remodeling, melanocyte function, and hepatocellular carcinoma development. These findings suggest that Fam114a1 could be a potential therapeutic target for related diseases [1,2,3].
