S. Interestingly, the MAD2L1 and BUB1B transcripts were also increased in CC (Table S3) suggesting that the corresponding proteins could be increased and prevent activation of APC/C. However, part of the CDC20 protein could remain free to bind and activate APC/C, as has been shown in transfected cells expressing the E6/E7 proteins [55]. CDC20 has been found to be upregulated in lung, pancreatic, and gastric cancers [58], as well as in CC [40,59]. CDKN3 is a dual-specificity protein phosphatase of the Cdc14 phosphatase group that interacts with CDK1 (CDC2) and inhibits their activity [60,61]. CDKN3 and other Cdc14 phosphatases have not been well studied; however, they seem to be essential for antagonizing Cdk activity in late mitosis, allowing cells to exit mitosis in telophase. Regulation of cytokinesis may be the 1 conserved function of the Cdc14 phosphatases. Although overexpression of CDKN3 has been KS-176 site associated with inhibition of cell proliferation in colon cancer cell lines [62], it has also been found to be overexpressed in breast, prostate, and lung cancers [63?5]. In agreement with our data, CDKN3, along with other genes, has been found to be associated with lower survival of patients with lung adenocarcinomas [63]. This is the first report in which CDKN3 was associated with cervical cancer (Table S6). PRC1 is involved in cytokinesis and is essential for controlling the spatiotemporal formation of the midzone and successful cytokinesis [66,67]. It is required for kinesin-family member 14 (KIF14)Mitosis as Source of Biomarkers in Cervical Cancer[68] and polo-like kinase 1 (PLK1) [69] localization to the central spindle and midbody. The suppression of PRC1 blocks cell division. The transcription of PRC1 is repressed by p53 and is one of the routes by which p53 stops the cell cycle at the G2/M checkpoint [70]. Since the E6 oncoprotein of HPV16 induces degradation of p53 in proteasomes, it is likely that in cervical carcinomas PRC1 is being overexpressed via this mechanism. It has been reported to be associated with liver cancer [71] and CC [40,42]. NUSAP1 is a nucleolar-spindle-associated protein that plays a role in spindle Sermorelin chemical information microtubule organization. This gene has not been described as associated with CC, but has been found to be upregulated in breast and melanoma cancers [72]. SYCP2 is a major component of the synaptonemal complex. This complex promotes that double strand breaks (DSB) are repaired by the homologous recombination pathway in meiosis [73]. The high levels of SYCP2 expression in the CCs examined in this work suggests that DSB are very common in some CC samples and that SYCP2 could be involved in DSB repair by the stimulation of homologous recombination pathway. Interestingly, this gene has been found to be upregulated in CC [45,46] and oropharyngeal squamous cell carcinomas positive for HPV16, but not in HPVnegative carcinomas [74]. Cell cycle is the main process altered in CC and is top ranked in all CC papers where biological processes have been analyzed [46]. Similarly, in the present paper, when the gene dataset was analyzed using the DAVID tool at medium stringency, the cell cycle process was shown to be the most enriched and it ranked at the top of the list (Table S5). However, the fact that M-phase processes were the most enriched in our dataset when the analysis was done at high stringency, suggests that the M-phase is the main altered 1407003 cell-cycle phase in CC. These findings are consistent with the alterations in.S.
