DAB2 and cancer: The ectopic expressions of Dab2 were observed in several human malignant cancer cell lines: Data pooled from eight studies in this meta-analysis showed that the ectopic expression of Dab2 were observed in 17 human malignant cancer cell lines, including: A549, LTE, H1299, SH-SY5Y, HT1080, et al. Dab2 was un-detectable in MCF7, T47D, ZR-75-1, Du145, et al.14,16,17,22,24-27 There was no significant difference between weak positive and absent expression of Dab2 in human cancer cells (OR = 1.04, 95% CI: 0.66 - 1.65, P = 0.85; I2 = 39.9%, P heterogeneity = 0.11) (Fig. 2B).
