Rbm34, an RNA-binding motif (RBM) protein, is involved in various biological processes. Although its exact essential function and associated pathways are not fully elaborated in the given references, it has been shown to have implications in cancer-related processes [1,2,3,5,6,7].

In hepatocellular carcinoma (HCC), overexpression of Rbm34 promotes tumor progression, correlates with poor clinicopathological features and prognosis. Knockout of Rbm34 significantly inhibits cell proliferation, migration, and xenograft tumor growth, and sensitizes HCC cells to sorafenib treatment. It also reduces FGFR2 expression and affects PI3K-AKT pathway activation in HCC cells [1].

In osteosarcoma, Rbm34 expression affects survival metrics, and knockdown of Rbm34 impedes the migratory and invasive capabilities of osteosarcoma cells. It is also associated with clinical prognosis, immune infiltration, and immunotherapy across various cancer types [2].

In addition, Rbm34 has been identified in relation to lactation traits in cattle, with a premature stop variant in the Rbm34 gene being a candidate causal mutation for recessive impacts on milk yield traits [4].

In conclusion, Rbm34 plays a role in tumor progression, especially in hepatocellular carcinoma and osteosarcoma, as revealed through knockout-based research. Its implications in cancer prognosis, immune-related aspects, and in cattle lactation traits highlight its importance in different biological contexts.
