<p>The vertebrate SIX genes are homologs of the Drosophila 'sine oculis' (so) gene, which is expressed primarily in the developing visual system of the fly. Members of the SIX gene family encode proteins that are characterized by a divergent DNA-binding homeodomain and an upstream SIX domain, which may be involved both in determining DNA-binding specificity and in mediating protein-protein interactions.

It appeared that studies of several cancer cell lines suggested that SIX1 may be overexpressed in multiple types of tumors.

(2003)</a> demonstrated that the Eya family has a protein phosphatase function, and that its enzymatic activity is required for regulating genes encoding growth control and signaling molecules, modulating precursor cell proliferation. The phosphatase function of Eya switches the function of Six1-Dach (<a href="/entry/603803">603803</a>) from repression to activation, causing transcriptional activation through recruitment of coactivators. The gene-specific recruitment of a coactivator with intrinsic phosphatase activity provides a molecular mechanism for activation of specific gene targets, including those regulating precursor cell proliferation and survival in mammalian organogenesis. Eya1 +/- Six1 +/- double heterozygous mice had a defect in kidney development, which was not observed in single heterozygotes for either gene deletion, suggesting that Six1 and Eya1 act in the same genetic pathway. Notably, there was a complete absence of all hypaxial muscle in Six1 -/- Eya1 -/- double knockout mice and severe reduction of epaxial muscle, a phenotype resembling that seen in mice homozygous for deletion of Myog and in double knockouts for MyoD/Myf5 (<a href="/entry/159990">159990</a>) and Pax3/Myf5. Interestingly, although mutation of Six1 or Eya1 has minimal or no effect on pituitary development, mice with both genes deleted have a pituitary that is approximately 5- to 10-fold smaller by volume than the wildtype gland. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=14628042" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p><p><a href="#1" class="mim-tip-reference" title="Bosman, E.

<p>The vertebrate SIX genes are homologs of the Drosophila 'sine oculis' (so) gene, which is expressed primarily in the developing visual system of the fly. Members of the SIX gene family encode proteins that are characterized by a divergent DNA-binding homeodomain and an upstream SIX domain, which may be involved both in determining DNA-binding specificity and in mediating protein-protein interactions. Genes in the SIX family have been shown to play roles in vertebrate and insect development or have been implicated in maintenance of the differentiated state of tissues (summary by Boucher et al., 2000). </p>

<strong>Cloning and Expression</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Boucher et al. (1996) cloned and sequenced a human SIX1 cDNA and showed by Northern blotting that it is expressed in adult skeletal muscle. The cDNA sequence and predicted protein sequence of the human and mouse genes are highly homologous, with 98% similarity over the entire predicted amino acid sequence. During mouse limb development at embryonic day 11.5, Six1 and Six2 are expressed distally over the posterior and anterior limb regions, respectively. However, by E14.5, expression of Six1 and Six2 is detected flanking the phalanges in domains corresponding to the anterior-posterior and dorsoventral axes, respectively. Six1 is also weakly expressed in skeletal muscles of the head and body during late development. </p><p>Ford et al. (1998) cloned the human SIX1 homeobox gene from late S phase mammary carcinoma cells and demonstrated that overexpression of SIX1 leads to an abrogation of the DNA damage-induced G2 cell cycle checkpoint. In addition, they found that overexpression of SIX1 occurs in a large percentage of mammary carcinomas and correlates strongly with metastatic breast disease. It appeared that studies of several cancer cell lines suggested that SIX1 may be overexpressed in multiple types of tumors. Thus, the studies linked SIX1 to the cell cycle as well as to tumor progression and provided further evidence that 'master regulators' involved in development may contribute to tumorigenicity. </p>

<strong>Gene Function</strong>
</span>

</div>
<span class="mim-text-font">
<p>Ridgeway and Skerjanc (2001) induced myogenesis in a mouse pluripotent stem cell line. Myogenesis was associated with increased expression of Pax3 (606597), followed by expression of the transcription factor Six1, its cofactor Eya2 (601654), and the transcription factor Mox1 (600147), prior to the induction of MyoD (159970) and myogenin (Myog; 159980) expression. </p><p>Yu et al. (2004) established highly and poorly metastatic rhabdomyosarcoma cell lines derived from a transgenic mouse model overexpressing Hgf/Sf (142409) and deficient for Ink4a/Arf (600160), in which skeletal muscle tumors reminiscent of those in embryonic rhabdomyosarcoma (268210) arise with very high penetrance and short latency (Sharp et al., 2002). Yu et al. (2004) then used cDNA microarray analysis of these cell lines to identify a set of genes whose expression was significantly different between highly and poorly metastatic cells. Subsequent in vivo functional studies revealed that ezrin, encoded by Vil2 (123900), and Six1 have essential roles in determining the metastatic fate of rhabdomyosarcoma cells. VIL2 and SIX1 expression was enhanced in human rhabdomyosarcoma tissue, significantly correlating with clinical stage. </p><p>Buller et al. (2001) analyzed the functional importance of Eya (EYA1; 601653) domain missense mutations with respect to protein complex formation and cellular localization. Previously described point mutations did not alter protein localization; however, 3 mutations (glu330 to lys, 601653.0009; ser454 to pro, 601653.0012; and leu472 to arg, 601653.0013) disrupted interactions between Eya and Six1 in both yeast and mammalian cells. Binding to Six2 (604994) was not impeded. </p><p>Grifone et al. (2004) found that among the Six and Eya gene products expressed in mouse skeletal muscle, Six1 and Eya1 accumulated preferentially in the nuclei of fast-twitch muscles. Forced coexpression of Six1 and Eya1 in the slow-twitch soleus muscle induced a transition to a fast-twitch fiber type, with activation of fast-twitch fiber-specific genes and a switch toward glycolytic metabolism. </p><p>SALL1 (602218) is a transcription factor that has a critical role in kidney development. Using gel retardation assays, reporter gene assays, and mutation analysis, Chai et al. (2006) showed that SIX1 directly bound the SALL1 promoter and induced SALL1 expression in a dose-dependent manner. </p><p>McCoy et al. (2009) found that misexpression of human SIX1 in adult mouse mammary gland epithelium induced tumors of multiple histologic subtypes in a dose-dependent manner. Most SIX1-induced tumors underwent an epithelial-to-mesenchymal transition (EMT) and expressed multiple targets of activated Wnt (see 164820) signaling, including cyclin D1 (CCND1; 168461). SIX1 promoted a stem/progenitor cell phenotype in mouse mammary gland and in SIX1-dependent mammary tumors. Coexpression of SIX1 and cyclin D1 was detected in several human breast cancers and was predictive of poor prognosis. </p><p>Independently, Micalizzi et al. (2009) showed that SIX1 overexpression in human and mouse mammary epithelial cells induced EMT and metastasis, both of which were dependent on the ability of SIX1 to activate TGF-beta (TGFB1; 190180) signaling. Breast cancer patients whose tumors overexpressed SIX1 had a shortened time to relapse and metastasis and an overall decrease in survival. Similarly, overexpression of SIX1 correlated with adverse outcomes in a number of other cancers, including brain, cervical, prostate, colon, kidney, and liver. Micalizzi et al. (2009) concluded that SIX1, acting through TGF-beta signaling and EMT, is a powerful and global promoter of cancer metastasis. </p><p>Delgado-Olguin et al. (2012) found that conditional deletion of Ezh2 (601573) in mouse anterior heart field resulted in right cardiac hypertrophy and fibrosis after birth. Gene expression profiling of Ezh2-knockout hearts revealed derepression of Six1, with concomitant activation of Six1-dependent skeletal muscle-specific genes. Overexpression of Six1 in cultured neonatal mouse cardiomyocytes resulted in hypertrophy comparable to that induced by the hypertrophic agonist endothelin-1 (EDN1; 131240). Knockdown of Six1 in Ezh2-knockout hearts completely rescued the cardiac phenotype. </p><p>Liu et al. (2019) showed that the SIX homolog family transcription factors SIX1 and SIX2 (604994) are integral components of the noncanonical NF-kappa-B (see 164011) signaling cascade. The developmentally silenced SIX proteins were reactivated in differentiated macrophages by NIK (604655)-mediated suppression of the ubiquitin proteasome pathway. Consequently, SIX1 and SIX2 targeted a subset of inflammatory gene promoters and directly inhibited the trans-activation function of the transcription factors RELA (164014) and RELB (604758) in a negative feedback circuit. In support of a physiologically pivotal role for SIX proteins in host immunity, a human SIX1 transgene suppressed inflammation and promoted the recovery of mice from endotoxic shock. In addition, SIX1 and SIX2 protected RAS (see 190070)/P53 (191170)-driven non-small-cell lung carcinomas from inflammatory cell death induced by small molecule activators of the noncanonical NF-kappa-B pathway. </p>

<p>Branchiootorenal syndrome (see 113650) is an autosomal dominant disorder characterized by hearing loss, branchial cleft fistulas or cysts, and renal dysplasia. Branchiootic syndrome (see 602588) is a related disorder without renal anomalies. Ruf et al. (2003) mapped a locus for the BOR/BO syndrome (BOS3; 608389) to chromosome 14q23. By direct sequencing of SIX1 exons, they identified 2 different mutations in the SIX1 gene in 3 kindreds with BOS3: tyr129 to cys (Y129C; 601205.0001) and arg110 to trp (R110W; 601205.0002). Both mutations are crucial for EYA1-SIX1 interaction, and the Y129C mutation, which is within the homeodomain region, is essential for specific SIX1-DNA binding. In a member of a fourth family, previously reported by Salam et al. (2000) with DFNA23 (605192), Ruf et al. (2004) identified a 3-bp deletion in the SIX1 gene (601205.0003). In addition to deafness, the patient had a solitary left hypodysplastic kidney with vesicoureteral reflux and progressive renal failure, suggesting that this family may have BOR/BO syndrome. </p><p>In 7 affected individuals from a large 5-generation Danish family with branchiootic syndrome, Sanggaard et al. (2007) identified heterozygosity for a missense mutation in the SIX1 gene (601205.0004). </p><p>By direct sequencing of the SIX1 gene in an affected member of a Tunisian family with autosomal dominant hearing impairment and preauricular pits mapping to chromosome 14q23, Mosrati et al. (2011) identified a heterozygous missense mutation (E125K; 601205.0005) that segregated with the phenotype in family. </p>

<strong>Animal Model</strong>

<span class="mim-text-font">
<p>Li et al. (2003) reported that Six1 is required for the development of murine kidney, muscle, and inner ear and that it exhibits synergistic genetic interactions with Eya factors. Li et al. (2003) demonstrated that the Eya family has a protein phosphatase function, and that its enzymatic activity is required for regulating genes encoding growth control and signaling molecules, modulating precursor cell proliferation. The phosphatase function of Eya switches the function of Six1-Dach (603803) from repression to activation, causing transcriptional activation through recruitment of coactivators. The gene-specific recruitment of a coactivator with intrinsic phosphatase activity provides a molecular mechanism for activation of specific gene targets, including those regulating precursor cell proliferation and survival in mammalian organogenesis. Eya1 +/- Six1 +/- double heterozygous mice had a defect in kidney development, which was not observed in single heterozygotes for either gene deletion, suggesting that Six1 and Eya1 act in the same genetic pathway. Notably, there was a complete absence of all hypaxial muscle in Six1 -/- Eya1 -/- double knockout mice and severe reduction of epaxial muscle, a phenotype resembling that seen in mice homozygous for deletion of Myog and in double knockouts for MyoD/Myf5 (159990) and Pax3/Myf5. Interestingly, although mutation of Six1 or Eya1 has minimal or no effect on pituitary development, mice with both genes deleted have a pituitary that is approximately 5- to 10-fold smaller by volume than the wildtype gland. </p><p>Bosman et al. (2009) reported 'catweasel' (cwe), an N-ethyl-N-nitrosourea-induced mutation that caused mild headbobbing in heterozygous cwe/+ mice. These mice lacked the eminentium cruciatum in the posterior crista and had extra inner hair cells in the organ of Corti. Bosman et al. (2009) identified cwe as a 411A-G transition in exon 1 of the Six1 gene, resulting in a glu135-to-gly (E135G) substitution of a highly conserved residue in the N-terminal part of the Six1 homeobox domain. The mutation did not alter Six1 expression, but it was predicted to destabilize binding of Six1 to DNA. Bosman et al. (2009) observed that the cwe/+ phenotype was less severe than the Six1 +/- phenotype. Homozygous cwe/cwe mice had a more severe phenotype than cwe/+ mice that resembled branchiootorenal syndrome, with extreme headshaking and circling behavior. Cwe/cwe animals appeared normal in most behavior tests, but they were deaf and lacked contact righting response and Preyer reflex. They also had severe vestibular abnormalities and defects in the inner and middle ear, lacked most sensory hair cells, and showed renal defects. Cwe/cwe embryos showed defects in sensory patch development as early as embryonic day 10.5. Bmp4 (112262), Jag1 (601920), and Sox2 (184429) expression was largely absent at early stages of sensory development, and NeuroD (see 601724) expression was reduced in developing vestibuloacoustic ganglion. Bosman et al. (2009) noted that htu/+ mice with a mutation in the Jag1 gene show a phenotype similar to cwe/+ mice. Experiments with cwe/+, htu/+, and double-heterozygous cwe/+ htu/+ mice suggested that Six1 acts upstream of Jag1 in the Notch signaling pathway. </p>

<p>In 7 affected individuals from a large 5-generation Danish family with branchiootic syndrome-3 (BOS3; 608389), Sanggaard et al. (2007) identified heterozygosity for a 364T-A transversion in exon 1 of the SIX1 gene, resulting in a trp122-to-arg (W122R) substitution at a conserved residue. The mutation was not found in unaffected family members or in 140 control chromosomes. </p>

<p>By direct sequencing of the SIX1 gene in an affected member of a Tunisian family with autosomal dominant hearing impairment and preauricular pits mapping to 14q23, Mosrati et al. (2011) identified a heterozygous c.373G-A transition, predicted to result in a glu125-to-lys (E125K) substitution at a conserved residue. Segregation of the variant with the phenotype was confirmed by PCR restriction fragment length polymorphism. The glu125 residue is located in the N-terminal arm and is likely to affect DNA binding. </p>
