The lncRNA, Malat1, controls the expression of genes involved in nuclear processes and synaptogenesis (Bernard et al., 2010), while the expression of the lncRNA PCAT-1 causes a homologous recombination deficiency and the suppression of the tumor suppressor BRCA2, which has been linked to cancer (Prensner et al., 2014). This evidence concerns the gene PCAT1 and cancer.
