Tcim, whose full name is not explicitly given in the provided references, is one of the genes whose expression appears to mediate the association between the MIND diet and dementia [1]. The MIND diet is related to a specific brain transcriptomic profile, and Tcim might be involved in the underlying molecular mechanisms linking this diet to cognitive health.

No information regarding KO/CKO mouse models or other loss-of-function experiments on Tcim was found in the provided references.

In conclusion, Tcim potentially plays a role in the relationship between the MIND diet and cognitive health, specifically in relation to dementia. Although the exact mechanism remains unclear due to lack of information from gene-knockout models, its identification as a mediating gene in this context provides a starting point for further research into understanding the molecular basis of how diet impacts dementia risk.
