Abstract
The pituitary tumor-transforming gene 1 (PTTG1) is an oncogene involved in chromosomal segregation, DNA repair, apoptosis, and metabolism. PTTG1 can be used for clinical diagnosis and treatment and is a potential target for oropharyngeal carcinoma. The proliferation and viability of Cal27 and FaDu cells were assessed using the CCK-8 assay. Real-time PCR and western blotting, respectively, were used to analyze the mRNA and protein expression levels of PTTG1 and IFIH1. The interaction between PTTG1 mRNA and the translational regulatory protein IFIH1 was analyzed using RNA pull-down, RNA immunoprecipitation, and luciferase reporter assays. PTTG1 protein was significantly overexpressed in oropharyngeal carcinoma, whereas PTTG1 mRNA was not. We hypothesized that a translation regulatory protein plays a post-transcriptional role in PTTG1. The IFIH1 protein specifically bound to the 42-52 nt region of PTTG1 mRNA, promoted the translation of PTTG1, and promoted the proliferation of oropharyngeal cancer cells. Administration of the PTTG1 inhibitor PHA-848125 and silencing of IFIH1 synergistically decreased the expression of PTTG1, inhibited the proliferation of oropharyngeal cancer cells, and indicated a good prognosis. We found that the IFIH1-PTTG1 axis could regulate the PHA-848125 response and functionally mediate inter-individual oropharyngeal cancer susceptibility and prognosis. This study aimed to confirm the upstream regulatory genes of PTTG1 and further investigate the specific interactions in this signaling pathway, which will provide a new approach for the treatment of oropharyngeal carcinoma.

Abstract
BACKGROUND Numerous studies have investigated the clinical significance of securin expression in solid cancers; however, the results have been inconsistent. Hence, we performed a meta-analysis of published studies to assess the clinical value of securin expression in patients with solid cancers. METHODS The Chinese National Knowledge Infrastructure, Web of Science, PubMed, and EMDASE databases were searched for eligible studies (from inception up to April 2021). Bioinformatics analysis based on The Cancer Genome Atlas dataset was also performed to evaluate the prognostic value of securin expression. RESULTS A total of 25 articles with 26 studies were included in the meta-analysis. The results of the meta-analysis implied that high securin expression was positively correlated with unfavorable overall survival (OS) (hazard ratio = 1.52, 95% CI, 1.33-1.73; P < .001) and lymph node metastasis (odd ratio = 2.96, 95% CI, 2.26-3.86; P < .001). Consistently, our bioinformatics analysis showed that increased securin expression was associated with worse OS and shorter disease-free survival in cancer patients. CONCLUSION Our study indicated that securin overexpression was positively associated with metastasis and inversely related to the prognosis of patients with solid cancers. However, additional high-quality studies should be conducted to validate these findings.

Abstract
BACKGROUND This study explored whether laryngeal carcinoma could be divided into different subtypes based on molecular differences using a molecular subtype-prediction model. METHODS We extracted data from the Cancer Genome Atlas and Gene Expression Omnibus databases and then performed unsupervised cluster analysis to identify discrete molecular subtypes of laryngeal carcinoma. Significance analysis of microarrays was performed to detect differentially expressed genes for each subtype, and gene set enrichment analysis and the GenCliP3 software were used to label gene functions and identify key pathways. RESULTS We categorized 126 patients into C1 and C2 molecular subtypes associated with pathologic grade. The C2 subtype appeared more aggressive, with a worse prognosis. The most significant enrichment pathway of the C2 subtype was the Hedgehog pathway, and GLI1 was a core gene. CONCLUSIONS Laryngeal carcinoma can be divided into two subtypes based on differences in molecular expression, which could identify key molecules associated with prognosis.

Abstract
Hepatocellular carcinoma (HCC) is the most frequent primary liver malignancy globally and the third leading cause of cancer-related death. Chemotherapy is one of the main methods in treating HCC, while recent studies have found that the resistance of HCC to chemotherapeutic drugs reduces the efficacy of the chemotherapy. Falcarindiol (FAD) is a cytotoxic and anti-inflammatory polyacetylenic oxylipin found in food plants of the carrot family (Apiaceae), while its role in HCC remains to be explored. Here, HCC cells (Huh7 and LM3) were treated with FAD at different doses. Cell proliferation was tested by the cell counting kit-8 (CCK-8) method and colony formation assay, while the apoptosis was monitored by flow cytometry. The profiles of apoptosis-related proteins (Bax, bcl2, and Caspase-3), DNA repair proteins (Rad51, BRCA1, and MDC1), and the signal transducer and activator of transcription 3 (STAT3)/Pituitary Tumor Transforming Gene 1 (PTTG1) were verified by western blot (WB) or quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The interaction between STAT3 and PTTG1 was verified by immunoprecipitation (IP). In addition, a xenograft tumor model was constructed in mice to explore the anti-tumor effects of FAD in vivo, and immunohistochemistry (IHC) was performed to count the number of Ki67-stained cells. As a result, FAD inhibited HCC cell proliferation and DNA repair, facilitated their apoptosis, and also enhanced cisplatin (DDP) chemosensitivity. The Combination Index (CI) evaluation showed that FAD and DDP had synergistic effects in repressing HCC cell proliferation. Besides, FAD dampened the STAT3/PTTG1 pathway expression. Further studies revealed that inhibiting STAT3 enhanced the inhibitive effect of FAD on HCC cells, whereas overexpressing PTTG1 attenuated the anti-tumor effect of FAD. Overall, our study illustrated that FAD is a potential anticancer drug and strengthens the chemosensitivity of HCC cells to DDP by inhibiting the STAT3/PTTG1 pathway.

Abstract
Background Pituitary tumor transforming genes (PTTG1, PTTG2, and PTTG3P) play key roles in the pathogenesis and development of human cancers. The studies show that overexpression of the PTTG genes is associated with tumor progression and migration. However, the function of the PTTG genes in the prognostic value of kidney renal clear cell carcinoma is rarely known by people. Methods The expression of PTTG family genes was analyzed by the ONCOMINE, Human Protein Atlas, GEPIA2, and UALCAN database. The relationship between PTTG family genes expression level and clinical indicators including prognostic data in kidney renal clear cell carcinoma was analyzed by GEPIA2, TCGA portal, and UALCAN. cBioPortal database was used to analyze the genetic mutations of differentially expressed PTTG family members. Similar genes of the PTTG family (90 in total) obtained from GEPIA2 and Metascape were used for GO enrichment to explore the interaction among similar genes. The online tools of Metascape and STRING were used for functional and pathway enrichment analysis. Results PTTG1, 2, and 3P mRNA and protein expression upregulated in kidney renal clear cell carcinoma kidney renal clear cell carcinoma patients compared with normal tissues. And higher expression level of PTTG family genes was associated with shorter overall survival (OS) and disease-free survival (DFS). Furthermore, overexpression of the PTTG family genes had been found correlated with individual cancer stages and pathological tumor grades. In addition, 18% of mutations in the PTTG family genes were associated with short-term survival in kidney renal clear cell carcinoma patients. Conclusions A single PTTG gene or PTTG family genes as a whole may be a potential prognostic biomarker for kidney renal clear cell carcinoma.

Abstract
Human T-cell lymphotropic virus type-1 (HTLV-1) is a pathogenic retrovirus that is associated with adult T-cell leukemia/lymphoma (ATL). Genetic instability is the hallmark of ATL. Cell cycle progression is needed for virus particle reproduction. HTLV-1 encoded Tax protein ultimately disrupts the mitotic spindle checkpoint, leading to incorrect chromosome segregation, resulting in aneuploidy. Cell cycle abnormalities have been described in T cells transfected with HTLV-1 virus in vitro, but not in HTLV-1 asymptomatic carriers. PTTG1 and HTLV-1 viral protein Tax exhibit a cooperative transforming activity. Overexpressed PTTG1 results in chromosome instability and aneuploidy, which has been suggested as a mechanism underlying PTTG1 transforming activity. Here we aimed to investigate cell cycle, DNA ploidy and PTTG1 mRNA expression in CD4+ and CD8+ T cells in healthy subjects (HS), HTLV-1 asymptomatic carriers and ATL patients. We have identified that HTLV-1 asymptomatic carriers have shown DNA aneuploidy and cell cycle arrest at cell cycle phase G0/G1 in CD4+ T cells. CD8+ T cells of HTLV-1 asymptomatic carriers also demonstrated DNA aneuploidy but without alteration in cell cycle. In ATL, CD4+ and CD8+ T cells present a higher number of cells in cell cycle S-phase and PTTG1 overexpression. These studies provide insight into malignant transformation of HTLV-1 asymptomatic carriers to ATL patients.
