Zc3hav1l-flox Mouse

Zc3hav1l, whose functions are still being elucidated, has been associated with various biological implications. In pigs, it may be involved in the regulation of porcine leanness as a nonsense mutation in Zc3hav1l on SSC18 has a direct effect on lean meat percentage [2]. In humans, from RNA-seq data of normal human mammary epithelial cells, an interchromosomal RNA fusion between ZC3HAV1L and CHMP1A was computationally detected and experimentally confirmed in multiple human cells and tissues, with three variants of the chimeric RNA detected, suggesting complex splicing likely via trans-splicing [1]. Also, in colon cancer, Zc3hav1l is part of a risk score system consisting of eight immune-related genes constructed to predict the prognosis of colon cancer patients [3].

Although no gene knockout (KO) or conditional knockout (CKO) mouse models are mentioned in the provided references, these findings indicate Zc3hav1l could potentially play a role in processes related to porcine leanness, human cell splicing, and colon cancer prognosis.

In summary, Zc3hav1l seems to be involved in multiple biological processes such as porcine leanness regulation, human cell RNA splicing, and in predicting colon cancer prognosis. While KO/CKO mouse models were not detailed in the given references, future studies using such models could further clarify its role in these and potentially other disease-related or biological processes.
