8 Shocking Details Relating To CX-5461

(C) Begg's funnel plots to test ... Publication bias Egger's test and Begg's funnel plot were used for the analysis of publication bias. The funnel plots of the CSS/OS and RFS/PFS/DFS analyses were almost symmetrical, and all P-values from the Egger's test were >0.05 (Fig. 4C and D). Therefore, no significant publication selleck bias was observed in the present meta-analysis. Discussion The EMT is a well-established mechanism that includes intercellular contact disruption and enhanced cell motility (47). Additionally, a burgeoning body of evidence has clearly demonstrated the involvement of EMT in the invasion and migration of tumor cells (14,32,43). Intracellular and extracellular factors are known to be capable of promoting or inhibiting EMT progression. In particular, the miR-200 family has been proposed to suppress EMT by directly targeting the transcriptional repressors of E-cadherin, zinc finger E-box binding homeobox 1 (ZEB1) and zinc finger E-box binding homeobox 2 (ZEB2), thus inducing E-cadherin upregulation (48). Conversely, inhibition of the miR-200 family would induce mesenchymal-like spindle morphology, which promotes cancer metastasis. As the most representative microRNA among the miR-200 family, miR-200c fulfills important roles in EMT RNA Synthesis inhibitor inhibition and in MET promotion. For instance, Marchini et al (20) demonstrated that several downstream targets of miR-200c, including vascular endothelial growth factor A (VEGFA) and tubulin, beta 3 class III (TUBB3), were significantly upregulated in patients with ovarian cancer who relapsed (20). Leskel? et al (21) suggested an inverse correlation between miR-200c and TUBB3 expression in advanced ovarian cancer. Furthermore, a marked inverse correlation of the expression levels of miR-200c and the mRNA levels of VEGFA was demonstrated in two independent cohorts Dipivefrine of ccRCC and normal tissues (49). Thus, miR-200c has been considered a tumor suppressor. However, a potential oncogenic role of miR-200c in human malignancies has also been reported. Tuomarila et al (25) demonstrated that progesterone receptor (PR)-negative cases with local or distant recurrence had higher expression levels of miR-200c compared with those without recurrence, suggesting that a high expression level of miR-200c is an independent factor for predicting poor survival rates in PR-negative breast cancer. Tejero et al (30) reported that high expression levels of miR-200c were associated with shorter OS of patients with NSCLC due to MET and angiogenesis (30). In addition, Hamano et al (39) indicated that the miR-200c-induced chemoresistance of esophageal cancer was mediated by the Akt pathway, showing that miR-200c overexpression was significantly correlated with a shortened OS (39). In the present meta-analysis, a significant association of the expression of miR-200c with outcome was observed for pooled CSS/OS (Fig. 2A). However, there was heterogeneity in both groups of outcomes (P
