Niharika, Ureka L, Roy A, Patra SK. Dissecting SOX2 expression and function reveals an association with multiple signaling pathways during embryonic development and in cancer progression. Biochim Biophys Acta Rev Cancer 2024; 1879:189136. [PMID: 38880162 DOI: 10.1016/j.bbcan.2024.189136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 06/03/2024] [Accepted: 06/10/2024] [Indexed: 06/18/2024]
Abstract
SRY (Sex Determining Region) box 2 (SOX2) is an essential transcription factor that plays crucial roles in activating genes involved in pre- and post-embryonic development, adult tissue homeostasis, and lineage specifications. SOX2 maintains the self-renewal property of stem cells and is involved in the generation of induced pluripotency stem cells. SOX2 protein contains a particular high-mobility group domain that enables SOX2 to achieve the capacity to participate in a broad variety of functions. The information about the involvement of SOX2 with gene regulatory elements, signaling networks, and microRNA is gradually emerging, and the higher expression of SOX2 is functionally relevant to various cancer types. SOX2 facilitates the oncogenic phenotype via cellular proliferation and enhancement of invasive tumor properties. Evidence are accumulating in favor of three dimensional (higher order) folding of chromatin and epigenetic control of the SOX2 gene by chromatin modifications, which implies that the expression level of SOX2 can be modulated by epigenetic regulatory mechanisms, specifically, via DNA methylation and histone H3 modification. In view of this, and to focus further insights into the roles SOX2 plays in physiological functions, involvement of SOX2 during development, precisely, the advances of our knowledge in pre- and post-embryonic development, and interactions of SOX2 in this scenario with various signaling pathways in tumor development and cancer progression, its potential as a therapeutic target against many cancers are summarized and discussed in this article.

Abstract
NF-Y is a Transcription Factor (TF) targeting the CCAAT box regulatory element. It consists of the NF-YB/NF-YC heterodimer, each containing an Histone Fold Domain (HFD), and the sequence-specific subunit NF-YA. NF-YA expression is associated with cell proliferation and absent in some post-mitotic cells. The review summarizes recent findings impacting on cancer development. The logic of the NF-Y regulome points to pro-growth, oncogenic genes in the cell-cycle, metabolism and transcriptional regulation routes. NF-YA is involved in growth/differentiation decisions upon cell-cycle re-entry after mitosis and it is widely overexpressed in tumors, the HFD subunits in some tumor types or subtypes. Overexpression of NF-Y -mostly NF-YA- is oncogenic and decreases sensitivity to anti-neoplastic drugs. The specific roles of NF-YA and NF-YC isoforms generated by alternative splicing -AS- are discussed, including the prognostic value of their levels, although the specific molecular mechanisms of activity are still to be deciphered.

Abstract
SOX2 is a transcription factor involved in multiple stages of embryonic development. In related reports, SOX2 was found to be abnormally expressed in tumor tissues and correlated with clinical features such as TNM staging, tumor grade, and prognosis in patients with various cancer types. In most cancer types, SOX2 is a tumor-promoting factor that regulates tumor progression and metastasis primarily by maintaining the stemness of cancer cells. In addition, SOX2 also regulates the proliferation, apoptosis, invasion, migration, ferroptosis and drug resistance of cancer cells. However, SOX2 acts as a tumor suppressor in some cases in certain cancer types, such as gastric and lung cancer. These key regulatory functions of SOX2 involve complex regulatory networks, including protein-protein and protein-nucleic acid interactions through signaling pathways and noncoding RNA interactions, modulating SOX2 expression may be a potential therapeutic strategy for clinical cancer patients. Therefore, we sorted out the phenotypes related to SOX2 in cancer, hoping to provide a basis for further clinical translation.

Abstract
BACKGROUND Nuclear Transcription Factor Y Subunit Alpha (NFYA), together with NFYB and NFYC, form a sequence-specific heterotrimeric nuclear transcription factor (NFY), but their functional role in hepatocellular carcinoma (HCC) is still unclear. In this study, we explored the association between the NFY subunit genes and the survival of primary hepatocellular carcinoma (HCC) patients in The Cancer Genome Atlas (TCGA). The transcript-specific effect on HCC cell growth was studied. MATERIAL AND METHODS RNA-seq data from the Genotype-Tissue Expression Project (GTEx) and TCGA were analyzed in combination. In vitro cellular and molecular studies were conducted using SK-Hep-1 and Hep3B cells. Pearson's correlation coefficients were calculated to assess correlations. Welch's unpaired t test and one-way ANOVA with post hoc Tukey's multiple comparisons were performed. Kaplan-Meier (K-M) survival curves were assessed by conducting log-rank (Mantel-Cox) test. RESULTS NFYA was the only prognosis-related gene. Among the 2 splicing transcripts of NFYA, the long isoform (NFYAv1, NM_002505.5) but not the short-form (NFYAv2, NM_021705.4) was significantly associated with worse progression-free survival (PFS) (high [n=179] vs low [n=179], HR: 1.657, 95% CI: 1.228-2.235, P<0.001) and disease-specific survival (DSS) (high [n=175] vs low [n=175], HR: 1.986, 95% CI: 1.269-3.108, P<0.001) in HCC patients. GO/KEGG analysis in TCGA confirmed that NFYAv1 and NFYAv2 co-expressed (|Pearson's r|≥0.6) genes in primary HCC patients were enriched in quite different GO/KEGG terms. NFYAv1 knockdown significantly decreased cell viability and increased G0/G1 cell cycle arrest. The shRNA only targeting NFYAv1 had a significantly stronger growth-inhibiting effect than the shRNA targeting both NFYAv1 and NFYAv2. CONCLUSIONS This study showed that NFYAv1 is a tumor-promoting transcript associated with poor prognosis of HCC.

Abstract
Cervical cancer is a leading women cancer globally with respect to both incidence and mortality. Its increased risk has been linked with HPV infection and genetic variations like single nucleotide polymorphisms (SNPs). Although, studies have been published which evaluates the effect of SNPs in a few candidate genes, however the role of number of regulatory SNPs (rSNPs) in cervical cancer is not available. As literature evidence has shown that non-coding rSNPs are related with increasing cervical cancer risk, we undertook this study to prioritize the important rSNPs and elucidate their role. A search was conducted in PubMed up to December 2020, which led to the identification of 263 articles and 969 SNPs in the non-coding region. These 969 SNPs were analysed through rSNPBase and RegulomeDB, leading to identification of 105 rSNPs. Afterwards, a regulatory module was constructed using protein-protein interaction data and a hub of highly interacting 23 target genes (corresponding to 34 rSNPs) was identified using MCODE. To further understand the mechanism of action of the 34 rSNPs, their transcription factor information with respect to cervical cancer was retrieved. To evaluate the pooled effect of these prioritized polymorphisms in cervical cancer patients, a meta-analysis was performed on 10,537 cases and 11,252 controls from 30 studies corresponding to 8 rSNPs. It led to identification of polymorphisms in IL6 (rs2069837), TGFB1 (rs1800469), TLR9 (rs187084) and MMP7 (rs11568818) which are significantly (p < 0.05) associated with increased cervical cancer risk at the population level. Overall, the study demonstrates that rSNPs targeting immune and inflammatory genes (IL1B, IL6, IL10, IL18, TGFB1, CCR5, CD40, TLR9, and MMP7) are associated with cervical cancer.

Abstract
Objectives Cervical cancer ranks as the fourth most common neoplasia in women worldwide in which epigenetic alterations play an important role. Several studies have reported pro-oncogenic role of the histone variant H2A.Z in different types of cancer; however, the role of H2A.Z in cervical cancer remains poorly studied. This study aimed to determine the potential role of H2A.Z in cervical cancer through a bioinformatic approach. Materials and Methods H2A.Z expression was analyzed in The Human Protein Atlas, The Cancer Genome Atlas, and Gene Expression Omnibus datasets. The promoter regions of H2AZ1 and H2AZ2 genes were downloaded from Expasy, and the prediction of transcription factor binding motifs was performed using CONSITE, Alibaba, and ALGGEN. ChIP-seq and RNA-seq data from HeLa-S3 cells were downloaded from ENCODE. The discovery motif was investigated using MEME-ChIP. The functional annotation was examined in Enrich. Results The expression of H2A.Z is elevated in cervical cancer. Interestingly, DNA methylation, copy number, and transcription factors AP2α and ELK1 are involved in H2A.Z overexpression. Additionally, H2A.Z is enriched on promoter and enhancer regions of genes involved in pathways associated with cancer development. In these regions, H2A.Z enables the recruitment of transcription factors such as NRF1, NFYA, and RNA Pol II. Finally, H2A.Z allows the expression of genes associated with proliferation in patients with cervical cancer. Conclusion Our findings suggest that H2A.Z overexpression and its presence in promoters and enhancers could be regulating the transcription of genes involved in cervical carcinogenesis.

Abstract
Cervical cancer is the fourth common gynecologic cancer and is considered as second leading cause of death among women. Various strategies are applied in treatment of cervical cancer including radiotherapy, chemotherapy and surgery. However, cervical cancer cells demonstrate aggressive behavior in advanced phases, requiring novel strategies in their elimination. On the other hand, SOX proteins are transcription factors capable of regulating different molecular pathways and their expression varies during embryogenesis, disease development and carcinogenesis. In the present review, our aim is to reveal role of SOX transcription factors in cervical cancer. SOX transcription factors play like a double-edged sword in cancer. For instance, SOX9 possesses both tumor-suppressor and tumor-promoting role in cervical cancer. Therefore, exact role of each SOX members in cervical cancer has been discussed to direct further experiments for revealing other functions. SOX proteins can regulate proliferation and metastasis of cervical cancer cells. Furthermore, response of cervical cancer cells to chemotherapy and radiotherapy is tightly regulated by SOX transcription factors. Different downstream targets of SOX proteins such as Wnt signaling, EMT and Hedgehog have been identified. Besides, upstream mediators such as microRNAs, lncRNAs and circRNAs can regulate SOX expression in cervical cancer. In addition to pre-clinical studies, role of SOX transcription factors as prognostic and diagnostic tools in cervical cancer has been shown.

Abstract
Cancer stem cells (CSCs) are tumor cells that share functional characteristics with normal and embryonic stem cells. CSCs have increased tumor-initiating capacity and metastatic potential and lower sensitivity to chemo- and radiotherapy, with important roles in tumor progression and the response to therapy. Thus, a current goal of cancer research is to eliminate CSCs, necessitating an adequate phenotypic and functional characterization of CSCs. Strategies have been developed to identify, enrich, and track CSCs, many of which distinguish CSCs by evaluating the expression of surface markers, the initiation of specific signaling pathways, and the activation of master transcription factors that control stemness in normal cells. We review and discuss the use of reporter gene systems for identifying CSCs. Reporters that are under the control of aldehyde dehydrogenase 1A1, CD133, Notch, Nanog homeobox, Sex-determining region Y-box 2, and POU class 5 homeobox can be used to identify CSCs in many tumor types, track cells in real time, and screen for drugs. Thus, reporter gene systems, in combination with in vitro and in vivo functional assays, can assess changes in the CSCs pool. We present relevant examples of these systems in the evaluation of experimental CSCs-targeting therapeutics, demonstrating their value in CSCs research.

Abstract
Portal vein tumor thrombus (PVTT) is one of the most serious forms of hepatocellular carcinoma (HCC) vessel metastasis and has a poor survival rate. However, the molecular mechanism of PVTT has not yet been elucidated. In this study, the molecular mechanism of AXL expressed in tumor-derived endothelial cells (TECs) in vessel metastasis was investigated. High AXL expression was observed in TECs, but not in the tumor cells of HCC patients with PVTT and this was associated with poor overall survival (OS) and disease-free survival (DFS). AXL overexpression was positively associated with CD 31 expression both in vitro and in vivo. AXL promoted the cell proliferation, tube formation, and migration of both TECs and normal endothelial cells (NECs). High expression of AXL in TECs promoted the cell migration, but not the proliferation of HCC cells. Further studies demonstrated that AXL promoted cell migration and tube formation through activation of the PI3K/AKT/SOX2/DKK-1 axis. AXL overexpression in HUVECs promoted tumor growth and liver or vessel metastasis of HCC in xenograft nude mice, which could be counteracted by treatment with R428, an AXL inhibitor. R428 reduced tumor growth and CD 31 expression in HCC in PDX xenograft nude mice. Therefore, AXL over-expression in TECs promotes vessel metastasis of HCC, which indicates that AXL in TECs could be a potential therapeutic target in HCC patients with PVTT.

Abstract
BACKGROUND/AIM Sex determining region Y (SRY)-box 2 (SOX2) is a transcription factor essential for the maintenance of proliferation and self-renewal of cancer stem cells and is associated with breast cancer initiation. Regulation of cancer stem cell plasticity by SOX2 requires both positive and negative SOX2 transcription factors, but the negative regulator is still largely unknown. MATERIALS AND METHODS SOX2 promoter-binding proteins were identified by liquid chromatography-mass spectrometry/mass spectrometry, luciferase assay, and chromatin immunoprecipitation. The effects of one such transcription factor on SOX2 expression was investigated by knockdown and overexpression experiments. RESULTS Non-POU domain-containing octamer-binding protein (NONO) (also known as 54-kDa nuclear RNA-binding protein, P54NRB) was identified as a SOX2 promoter-binding protein and a negative regulator of SOX2 expression. Its activity was controlled by its coiled-coil domain and the C-terminal domain. CONCLUSION These results suggest that NONO acts as a key regulator of SOX2 transcription through the repression of SOX2 promoter activity in breast cancer cells.

Transcription factor NFYA promotes G1/S cell cycle transition and cell proliferation by transactivating cyclin D1 and CDK4 in clear cell renal cell carcinoma. Am J Cancer Res 2020; 10:2446-2463. [PMID: 32905496 PMCID: PMC7471361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Accepted: 07/10/2020] [Indexed: 06/11/2023] Open
Abstract
NFYA (nuclear transcription factor Y, subunit A) is a CCAAT-binding transcription factor. Accumulating evidence suggests that NFYA plays an important role in breast, ovarian, lung and gastric cancer. However, the role of NFYA in clear cell renal cell carcinoma (ccRCC) remains unclear. In this study, it was discovered that the expression of NFYA is elevated in tissues of ccRCC patient and high NFYA expression is linked to poor overall survival in ccRCC patient. Inhibition of G1/S cell cycle transition and decreased cell proliferation were observed upon NFYA knockdown in ccRCC cells. Moreover, further investigation revealed that NFYA binds directly to the promoter region of both CDK4 and cyclin D1 (CCND1) thus transactivating their expression, resulting in RB phosphorylation and the activation of subsequent E2F pathway activation. Taken together, these findings imply the oncogenic role of NFYA in ccRCC progression and its potential as a target for ccRCC therapy.

Abstract
Background The purpose of this study was to explore the effects of the Na+/K+ ATPase inhibitor ouabain in regulating osteosarcoma (OS) cell stemness. Material/Methods Western blot, qPCR, sphere-forming analysis, DNA methylation analysis, and Ca2+ concentration detection were performed to evaluate the stem-like traits of cells and ouabain-induced effects and related mechanisms on OS cell stemness. Cell viability assessment was performed to evaluate the effect of ouabain on OS cell chemosensitivity. Results Ouabain reduced the ALDH1 activity, the expression of critical stemness regulators, sphere size and number, and migration, invasion, and adhesion ability, but had little effects on cell viability. Additionally, the intracellular Ca2+ concentration and methylation level of the critical stemness regulators were higher in OS cells than in spheres formed by OS cells. Mechanistic studies revealed that ouabain leads to DNA methylation of stemness markers through increasing intracellular Ca2+ concentration. Notably, inhibition of Ca2+ channel or DNA methylation rescued the inhibition of ouabain on OS cell stemness. Additionally, ouabain enhances cisplatin sensitivity of OS cells, which is involved in Ca2+ channel and DNA methylation. Conclusions This work provides a potential compound for treating OS patients, especially OS patients with chemoresistance.
