Several years ago the Aldaz laboratory discovered a putative tumor suppressor gene (WWOX) affected in breast and many other cancers. This gene spans the second most common chromosomal fragile site, FRA16D and as consequence is frequently affected by genomic abnormalities and chromosomal rearrangements. A mouse conditional KO model has been developed for better understanding the role of WWOX in cancer. Interestingly, the WWOX locus was also shown to be a target in familial dyslipidemias and metabolic syndrome related conditions. Indeed, we recently demonstrated that WWOX modulates HDL metabolism and lipoprotein gene expression. In other recent collaborative studies it has been confirmed that WWOX is found mutated in a new form of autosomal recessive cerebellar ataxia with epilepsy and mental retardation. In summary, multiple approaches are being pursued at Dr. Aldaz's lab to understand the role of WWOX not only in cancer but also in other important human pathological conditions.
