Amplification and overexpression of the SOX2 oncogene represent a hallmark of squamous cancers originating from diverse tissue types.

We identify a single enhancer e1 that predominantly drives SOX2 expression. Repression of e1 in SOX2 -high cells causes collapse of the surrounding enhancers, remarkable reduction in SOX2 expression, and a global transcriptional change reminiscent of SOX2 knockout. The e1 enhancer is driven by a combination of transcription factors including SOX2 itself and the AP-1 complex, which facilitates recruitment of the co-activator BRD4. Our study shows that squamous cancers selectively amplify a predominant enhancer to drive SOX2 overexpression, uncovering functional links among enhancer activation, chromatin looping, and lineage-specific copy number amplifications of oncogenes.

Lineage-specific oncogenes represent a class of genes that play important roles in the normal development of specific cell lineages, but drive tumorigenesis when dysregulated. SOX2 is also essential in maintaining the self-renewal ability of basal cells 7 , which have been reported as the cell of origin for squamous cancers, the most common type of solid tumors 8.

Squamous cancer can originate from diverse tissues such as lung lung squamous cell carcinoma; LUSC , cervix cervical squamous cell carcinoma; CESC , skin, esophagus esophageal squamous cell carcinoma; ESSC , and upper digestive tissues in the head and neck head and neck squamous cell carcinoma; HNSC.

Genomic analyses have revealed that the SOX2 gene is widely amplified and overexpressed in squamous cancers, nominating SOX2 as a lineage-specific oncogene 9 , 10 , 11 , 12 , 13 , 14 , 15 , Indeed, previous in vivo studies have shown that Sox2 overexpression, together with the inactivation of tumor suppressors such as Pten or Lkb1 , drives the formation of mouse lung squamous cancers 8 , 17 , In addition to squamous cancer, SOX2 amplification and overexpression have also been reported in glioma 19 , a common type of brain tumor that includes low-grade glioma LGG , glioblastoma GBM , and several other subtypes.

SOX2 overexpression in cancer cells has been largely attributed to copy number amplifications of the SOX2 gene itself 9 , 10 , 11 , 14 , 15 , 16 , However, our understanding of oncogene copy number amplifications is evolving. We and others have recently shown that noncoding enhancers outside oncogenes such as MYC , MYCN , AR , KLF5 , and EGFR are selectively amplified with or without their respective oncogenes 5 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , demonstrating novel mechanisms that transcriptionally activate oncogenes in diverse cancer types.

Therefore, we decided to revisit the SOX2 locus and its associated copy number changes. Here, we reveal distinct copy number profiles at the SOX2 locus between squamous cancers and gliomas, which corresponds to the distribution of lineage-specific potential regulatory elements.

Focusing on the noncoding region that is selectively co-amplified with SOX2 in squamous cancers, we discover a single predominant enhancer that is necessary and sufficient for SOX2 activation. Furthermore, we delineate its relationship with the surrounding enhancers, identify its associated transcription factors, reveal its vulnerability to bromodomain protein degradation, and illustrate its impact on 3D chromatin architecture. Our study reveals the functional link among enhancer activation, enhancer—promoter interactions, and lineage-specific copy number amplifications in cancer.

Squamous cancers are known to acquire arm-level or broad amplifications at the chromosome 3q arm where SOX2 resides TCGA squamous cancers and gliomas with SOX2 focal amplifications are associated with higher SOX2 expression, as compared to samples with non-focal amplifications or samples without amplifications Supplementary Fig.

Source data are provided as a Source Data file. We hypothesized that the distinct copy number profiles between these cancers may be attributed to lineage-specific distribution of regulatory elements. Therefore, we analyzed the assay of transposase accessible chromatin-sequencing ATAC-seq data from TCGA, which profiled genome-wide chromatin accessibility to identify potential regulatory elements in diverse types of human primary tumors These regions exhibit little chromatin accessibility in gliomas, suggestive of their squamous cancer-specific function Fig.

We then calculated cancer specificity Z -scores for each of the TCGA-annotated chromatin-accessible sites by comparing the ATAC-seq signal across all the profiled cancer types, which highlighted the unique spatial distribution of squamous cancer- and glioma-specific chromatin accessibility Fig.

Collectively, these data suggest that these two cancer types may selectively amplify lineage-specific regulatory elements together with the SOX2 oncogene Fig. We next sought to interrogate the relationship between the SOX2 gene and the potential regulatory elements. The human genome is organized into series of insulated neighborhoods or topologically associating domains demarcated by CCCTC-binding factor CTCF binding, which restrict promoter—enhancer interactions We found that the SOX2 promoter resides at the boundary of two adjacent insulated neighborhoods that were previously identified from CTCF chromatin interaction analysis with paired-end tag ChIA-PET sequencing analysis 35 , suggesting that the SOX2 promoter may have access to regulatory elements from both ends Fig.

The super-enhancer region shared by the listed SOX2 -high squamous cancer cell lines is highlighted. The color intensity corresponds to the number of PETs supporting each of the loops. Given the high frequency of SOX2 focal amplifications in squamous cancers, in addition to previous in vivo evidence demonstrating the oncogenic significance of SOX2 overexpression in squamous cancer 8 , 17 , 18 , we focused on characterizing the functional importance of the squamous cancer-specific chromatin-accessible regions co-amplified with SOX2.

We first aimed to assess their enhancer activity and physical interaction with the SOX2 gene promoter. We found that several of the squamous cancer-specific chromatin-accessible regions exhibit strong and consistent H3K27ac signals Fig.

In particular, three individual candidate enhancers, which we refer to as e1—e3, form a super-enhancer element chr,,—,, as defined by strong and condensed enrichment of H3K27ac signal across SOX2 -high squamous cancer cell lines Fig. Nearby candidate enhancers e4—e5 are also enriched with varying levels of H3K27ac in these cell lines Fig. Previous studies have identified a super-enhancer element that drives Sox2 expression in mouse ESC 41 , We applied LiftOver 43 to identify mouse genomic regions that are conserved to the human squamous cancer-specific enhancers including the e1—e3 super-enhancer.

Our findings suggest that this set of candidate enhancers is specific to SOX2 -high squamous cancer cells. The results consistently show that among the enhancers, the super-enhancer constituents e1—e3 have the strongest physical interaction with the SOX2 promoter region.

Taken together, these data support e1—e3 as likely functional enhancers of the SOX2 oncogene in squamous cancers. Focusing on the enhancers e1—e3 within the squamous cancer-specific super-enhancer as well as the adjacent enhancers e4—e5, we sought to interrogate their impact on SOX2 expression. In addition, repression of e1 resulted in clear reductions in the protein levels of SOX2, as revealed by immunoblotting, in all the six cell lines Fig.

Previous studies have shown that the proliferation of squamous cancer cells with SOX2 overexpression are dependent on the SOX2 gene 9 , We also transplanted the LK2 cells with and without e1 repression into flanks of nude mice, which showed that activity of the e1 enhancer is required for in vivo tumor growth Fig. The expression level of SOX2 was normalized to cells treated with sg-NC 1 that has no recognition site in the genome. P values are derived from two-sided t tests.

Two separate sgRNAs sg-e1 1 and sg-e1 2 were used to target the e1 enhancer in six squamous cancer cell lines. The immunoblotting experiment was repeated once independently with similar results. Cell numbers were counted 6 days post seeding and normalized to the sg-NC 1 control.

Error bar: standard error of the mean. The SOX2 gene encodes an SRY-box transcription factor that is involved in both transcriptional activation and repression We thereby reasoned that, in addition to reduced SOX2 expression, repression of e1 may also result in dysregulation of SOX2-associated gene expression programs. Genes activated by e1 are enriched in squamous cancer-related pathways such as MAPK signaling and Hedgehog signaling Supplementary Table 1.

Collectively, these results demonstrate the critical role of the e1 enhancer in SOX2 activation and SOX2-associated cellular and molecular phenotypes. We then went on to test if e1 and the surrounding enhancers directly regulate any other genes in addition to SOX2. Among them, the SOX2 promoter has the strongest interactions with these enhancer anchors.

Given the predominant role of the e1 enhancer in SOX2 regulation, we sought to examine structural variants targeting e1 in squamous cancers. Duplications in 12 of the cases contain both SOX2 and e1. Interestingly, four tumor samples harbor duplications of only the enhancer region without the SOX2 gene Supplementary Fig.

The presence of tandem duplications of just the enhancer region further highlights the importance of the e1 enhancer in squamous cancer. We next aimed to assess the functional link of e1 with the surrounding enhancers. Distal enhancers activate target gene expression by recruiting transcriptional coactivators such as the bromodomain protein BRD4 and the mediator complex that promote POL2 elongation Repression of e1 decreased recruitment of BRD4 at not only e1 but also e2—e7 Fig.

The results consistently show that the activity of e1 is required for BRD4 recruitment at the surrounding enhancers Fig. The expression level was normalized to the sgAAVS1 control. ChIP enrichment was normalized to DNA concentration of each sample measured by Qubit and then to sonicated genomic input. To address this, we performed a rescue experiment by using the doxycycline-inducible SOX2 expression system in KYSE cells with and without e1 repression. We found that ectopic expression of SOX2 only rescued These results demonstrate that the enhancers e2—e5, but not e6—e7, are directly dependent on e1 to varying levels, defining an e1—e5 enhancer cluster.

We next sought to identify transcription factors that may contribute to e1 activity. Motif analysis of the e1 enhancer chromatin-accessible region identified DNA sequences recognized by multiple transcription factor families Fig. The combinations of transcription factor motifs are different between these two tested cell lines, which is likely because that they represent two distinct types of squamous cancers.

Despite the subtype difference, the transcriptional regulatory activity of e1 in both of the cell lines is dependent on the motifs recognized by SOX2 SOX family motif and the AP1 complex Fig.

Combinatorial disruptions of the motifs also caused reductions of BRD4 binding at not only e1 but also e2—e5 enhancers Fig. Although some of the candidate functional motifs were also found in the e2—e5 enhancers, a full collection of the motifs was only observed at e1 Fig.

Given the strong binding of the coactivator BRD4 at the e1 enhancer, we reasoned that the activity of e1 and the associated SOX2 overexpression may be sensitive to BRD4 perturbation.

The expression level was normalized to the DMSO controls. The expression level was normalized to the DMSO control. We then sought to assess if BRD4 degradation affects the chromatin interaction between the e1 enhancer and the SOX2 promoter.

Surprisingly, despite the dramatic response of e1 activity and SOX2 expression to BRD4 degradation, no appreciable change was observed for the chromatin interaction between e1 and the SOX2 promoter Fig. We next aimed to investigate if activation of e1 is sufficient to drive SOX2 expression. Activation of e1 resulted in 8—fold increases of SOX2 expression averaged value of two separate sgRNAs across the tested cell lines, demonstrating that e1 is sufficient for SOX2 activation Fig.

As compared to e1, activation of e2—e8 elements have modest or minimal effects on SOX2 expression, again highlighting the predominant role of e1. Activation of e6—e8 that are next to LINC TSS resulted in 10—fold increases of LINC expression, which agrees with their roles as a promoter or promoter-proximal elements for this noncoding gene.

The expression level was normalized to the negative control sg-NC 1. We also observed increased chromatin interactions between SOX2 and other enhancers surrounding e1, suggestive of a reconstitution of the chromatin architecture at the SOX2 locus.

Taken together, we show that activation of e1 is sufficient to bridge the e1 enhancer to the SOX2 promoter, which results in transcriptional activation of the SOX2 oncogene in squamous cancer cells illustrated in Fig. We and others have previously shown that overexpression of oncogenes can be driven by copy number amplifications of distal enhancers 5 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , Here, we show that this phenomenon extends to lineage-specific enhancers in a cancer type-specific manner.

The phenomenon is likely caused by the unique chromatin architecture surrounding the SOX2 gene: 1 glioma- and squamous cancer-specific enhancers are distributed in two adjacent insulated neighborhoods demarcated by CTCF binding; 2 SOX2 resides right at the boundary of the two neighborhoods so that it has access to both.

A recent study showed that copy number amplifications of oncogenes including SOX2 may occur as different forms of structural events such as linear tandem duplications, chromosomal rearrangements, or extrachromosomal circular DNA We reveal that SOX2 and distal enhancers that are looped to the SOX2 promoter are often co-amplified in squamous cancers, suggesting a common transcriptional regulatory mechanism that may be shared by different structural forms of SOX2 amplifications.

Lineage-specific oncogenes are known to be driven by condensed clusters of enhancer elements, namely super-enhancers or stretch enhancers 55 , 56 , 57 , yet the hierarchical structures for most of these enhancer clusters remain largely unknown.

For volt gate openers, a volt transformer will be needed not included. If playback doesn't begin shortly, try restarting your device. As you will see below, not every type of cell site is mounted to a cell tower. The widespread use of cell phones in recent decades has led to a large increase in the number of cell phone towers also known as base stations being placed in communities. Potential and current applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, and 3D television. Higher frequency reuse leads to smaller cells that may cause intra-cell interference or higher noise figures due to reduced power levels. The range will be up to feet. To avoid performance issues none of these values should be in, or dip into the red. An amplifier boosts the signal being received by the outside Many people seem to not worry about living or working in close proximity to cell towers and antennas. This means it will take 5G a long time to reach rural areas.
